FPGA is clocked at 90 MHz and is 3-5 times faster in raytracing then a Pentium4 CPU with 30 times more MHz.

I am really not surprised at the performance as most anytime you build code into hardware, it is significantly faster. For instance, I used to have a Radius 4 DSP Photoshop accelerator card in my old 68030 based Mac IIci I bought in 1990 that would run Photoshop filters significantly faster than even my much later PowerPC based PowerMac 8500 purchased in 1996 with faster hard drives and more memory.

The same sorts of benefits can be seen in vector math for optimizations that have been built into the G4 and G5 chips with Altivec [] .

So, the question is: Can these guys get ATI or nVidia to buy their chip?

As an FPGA, no. NVIDIA et al would find it to expensive. But if they can roll their Verilog/VHDL code into an ASIC without to much trouble, it might be cost effective enough to catch the gamer and CAD markets. And as a side benefit, an ASIC should potentially run even faster thus giving even more amazing performance. In fact, without knowing what these guys are up to, I'd bet that is in their business plan.

TLLOTS (827806) | more than 9 years ago | (#11940534)

It's doubtful that people from ATi or nVidia would have anything more than a casual interest in such a chip. More than anything with the way GPU's have been heading, this device would be more of a backwards step than a forwards one. GPU's these days are far more flexible than they used to be, and there's every indication that trend will only continue, allowing developers to do what they want with the hardware, rather than being told what they can do with it and having no real choice either way.

So to sum up, don't expect to see vastly specialised GPU's for raytraycing hitting the market, at least not for the mainstream buyer. It's more likely that we'll see GPU's become more generalised to the point where raytracing can implemented on software. Will they be as fast as a purpose built chip like this? No, more than likely they won't. Will developers be able to do a whole lot more with them? Most definitely, and though that will come at a significant performance penalty for the moment, I think it's the right trade off to make as we should see far more creative uses of hardware put into practice, such as work being done already to use GPU's for something other than Graphics Processing.

mrgreen4242 (759594) | more than 9 years ago | (#11940630)

I think there may be a market here. Say, for example, that the next generation of Unreal or Doom engine is designed around something like this. The SOFTWARE vendor could potentially, assuming they could get the cost down far enough, offer some sort of PCI or even better USB2/FW hardware accelerator bundled WITH the game.

Think of it like this... Unreal 4 or whatever the next next gen will be decides to partner up with these guys. They develop an engine that runs at 60fps with amazing graphics, etc. You can buy the USB3 or FW1600 or whatever add-on needed for the game for, say, $50, or a bundle for $75 that has the addon and the game. The development cycle would be much easier as there is only one type of hardware to worry about, and the consumer would win as they could get the new hottness game without having to drop $300 on a new new video card.

It could also serve as an amazingly effective copy protection scheme. Can't very well play the game without the required accelerator.

Seems possible to me.

Do you know what an FPGA is? (5, Interesting)

fireboy1919 (257783) | more than 9 years ago | (#11940683)

You're to be describing this as if it's some kind of custom hardware with many limitations.

This could not be further from the truth. FPGAs are more flexible than any of their counterparts. FPGA stands for "field programmable gate array," and are basically a matrix of memory elements (at the very least latches) connected to gates that configured to be a particular type of gate via a ROM or something similar.

It's kind of like a chip emulator written in hardware. You may be wondering why we don't use these all the time. First, they're a lot more expensive, bigger, and more power consuming than their one-chip cousins. Second (as if that isn't really enough), they're usually 2-5 times slower than the same logic on a custom chip.

So the big question is why should we use them? What improvements can they give that normal chips can't?

The big gain is when you want to optimize the hardware for a specific application and be able to change it. These were used in high end digital video cards to be able to handle whatever kind of signal is actually output by whatever kind of camera you've got (I can only assume this is still the case, but I stopped keeping track about 2000).

I don't know if the people who wrote this thing take advantage of this idea within their design, but it's a possibility.

Re:Hardware encoding (4, Interesting)

moosesocks (264553) | more than 9 years ago | (#11940627)

unlikely. the current generation of 3d cards are all polygon-pushers. Direct3D/OpenGL are all about polygons. virtually all raytracing is done by the CPU.

Of course, raytracing produces beautiful results compared to the other methods of 3d graphics, but it is MUCH more expensive in terms of CPU cycles on today's CPUs and non-existant on graphics chips -- the first gfx chips were polygon-based because drawing polygons is indeed easier than raytracing even with specialized hardware. of course, specialized hardware definitely helps polygons as well. my 300mhz/whatever TNT2 can render a scene as fast as the fastest pentiums today can using software rendering.

all of the big renderfarms rely exclusively on the CPU to do their animations. this could change all that. I for one look forward to seeing the potential this has.

Re:Hardware encoding (2, Insightful)

Anonymous Coward | more than 9 years ago | (#11940689)

Ray tracing and the current OpenGL/Direct3D way of rendering images are completely different. With OpenGL the rendering system renders a polygon to the frame/z buffer and can pretty much forget about its existance from that point on, meaning reduced memory overheads. Raytracing on the other hand requires every object in the scene to be accessible to render any pixel, each pixel "ray" needs to be tested against all objects in the scene to see which one it hits. This also causes problems moving from the current way programs send polygons to OpenGL to the way required for Raytracers, as I said earlier OpenGL can render and forget, whereas a raytracer can't.

Once those problems have somehow been solved (I don't like the thought of storing 100+million triangles+textures+material info in a video cards memory) then raytracing provides some nice benefits, like parallel rendering - each pixel can be rendered completely independant of any other pixel. Running at 1024x768 could possibly make use of 1024x768 raytracing chips running in parallel! The actual process of raytracing is fairly simple and very elegant (zero overdraw and reflections that can be implemented in a couple of lines of code on a suitable raytracing design), which to me means it is a better solution than all the hacks required to make OpenGL style rendering work. I'm not saying OpenGL is bad, in fact its amazing what can be done with current rendering techniques, but those techniques have come about largely as ways around the problems created by a sub-optimal process which was designed as a way to get around having to keep everything in memory.

Algorithms that are dependant on monte carlo sampling would benefit. This includes ambient occlusion, path tracing, and even subsurface scattering (both single and multiple scattering).

Re:How, Exactly? (2, Interesting)

The boojum (70419) | more than 9 years ago | (#11940757)

How about non-tesselated geometry? You can have high detail curved surfaces without turning everything into a dense polygon mesh. That in turn lowers the memory and rendering requirements so you can apply those resources to proper detail instead.

Or how about global illumination lighting effects? Truely emissive surfaces and area lights? As a hobbyist map maker, I would kill to have an engine that supported these; imagine being able to just tag the sky as an emmisive surface and have the entire level lit up and shadowed accordingly without having to painstakingly add bounce lights everywhere and tune them till they looked correct.

Another good argument that I've heard is based on the complexity of the algorithms. GPU style rendering is inherently order O(n) on the number of items in the scene. While ray-tracing has a high constant factor, a good ray tracing acceleration structure makes the problem O(log n) -- as the scene grows the time to ray trace gets closer to the time to GPU render it. Admittely you can do much the same with the GPU: there's a lot of stuff like BSP trees and bounding volume heirarchies and frustrum culling that you can do to speed it up, but then you're already applying ray-tracing techniques anyway, and now you're really talking about something that's more of a hybrid with the CPU just doing the ray-tracing part.

Re:oh yeah (4, Interesting)

forkazoo (138186) | more than 9 years ago | (#11940655)

It's not amazing at all. When nVidia started making 3D accelerators, OpenGL was a mature, common API. Direct X was gaining traction. DCC and game programmers were familiar with the immediate mode API's, and were making programs that used them.

By making a card that rendered in immediate mode, nVidia had, ya know, a market. If they created a raytracing card, they would have needed to invent a new API to run it. They would have been the only ones with a card that used the API. Because they would have had a very small installed base, nobody would have written programs to take advantage of the API. Other companies have made raytracing accelerators. This isn't new. Most of them have not done incredibly well because there is so little actual use for the product.

Think of it this way... How many programs have you seen written for the 3DFX glide API? So, if you are one of the people who still has a glide card, but it was designed so that it couldn't do OpenGL becuase it used completely different technology, how useful would it be to you?

Personally, I'd love a card like that, if it was well supported by Lightwave, and had a vibrant developer community, and multiple vendors making cards for the raytracing API, and I was sure it wouldn't disappear soon.

Anonymous Coward | more than 9 years ago | (#11940524)

I was seated out in the garden, behind the kitchen in or favourite
place, which was a long table and chairs that had an umbrella covering
the lot. You know the type, where the umbrella goes through the middle
of the table. The sun in summer is always pretty bad here, so even
sitting in the back yard mid-morning is a touch too warm at times.

The ladies this morning were a bit slow off the mark, but that was
nothing new. My wife tended to fall out of bed maybe around nine on
weekends, and Arundhuti was worse, often getting up around lunchtime.
Around 11 I was surprised to see both ladies, my wife and Arundhuti,
coming out of the kitchen and across the grass dressed in those
wrap-around sarongs that tie up just over the breasts. Both had picked
rather red or orange colours which looked rather bright and nice in the
back yard. I complimented them on their attire as they sat to join me.

We sat for a while, drinking some water or lemonade, and just talked
about university, our upcoming holiday interstate. My wife got up and
excused herself, saying that she needed to go to the toilet for a
while. We said the usual comments about having fun and not falling in,
and waved her off.

"Damn", Arundhuti said.

I chuckled. "Why?"

"Because I needed to go just now too." She brightened. "You
wouldn't mind if I went here, would you? She gave me one of those
pretty smiles that don't permit a guy to say other than OK.

"Sure, why not. Knock yourself out! I'll keep an eye out for the
boss's return!"

"Thanks", she said. With that, she turned her chair side on to the
table, and leaned back in the chair. Then she just pulled the cloth of
the sarong from under her backside, so that it bunched up in the small
of her back. What was revealed to the sun and morning air was her
naked pussy!. She pulled her feet up onto the chair so that she was
looking between her knees. Looking at me a little uncertainly, with a
wry grin, she peered between her legs, visibly relaxed and with a
glance towards the kitchen window, , put her hands on either side of
her pussy and pulled the lips apart to expose her inner parts to the
air. I was transfixed with fascination as I watched her. She started
to pee, a small dribble to start with and then, as she relaxed more,
released a stream of pee that arced into the air about her head height,
and landed around a metre or so beyond her butt. I was rather
impressed. Not only did she spill none on her chair, but also the
stream of pee in the air caught the sunshine rather well and to my mind
was rather beautiful. I must confess that I also liked the display of
her puckered anus, rather cute as well.

Arundhuti had smiled the whole way through. Her pleasure in the
release of her pee was obvious. She sat back in her chair, restored
her clothing, and gave me a huge smile.

"That was so cool, " she enthused. "I've always wanted to do

Arundhuti was relaxed and drinking at the table again when her mother
returned. I had to hide a hardon from both the eroticism of
Arundhuti's act, as well as just the sheer beauty of her pussy and
asshole in the sun! We enjoyed the rest of the morning outside.

After lunch my wife had to go to the hairdresser. I said I would
shower and read a book while she was gone. Arundhuti had already
scooted to the quiet of her room. As the car left the driveway, I
heard Arundhuti's door open, and her pixie like face poke out, long
hair swinging beside it.

"Is she gone?", she asked.

"Yeah, sure, why?" I replied in confusion, the shower temporarily

"I'll show you!", she replied. Arundhuti exited her room,
dressed as before.

She padded on bare feet on the tiles of the hallway. I followed
curious out to the kitchen, and back out to the yard.

"I could see that you liked what I did before." she announced. I
want to try something else.

"OK, " I said, as we were on the grass, "what would you like to

First off, lets get nude. Mum's gone, and she's the only one who
bothers with clothes here"

"Fine by me!", I announced. I stripped off my t-shirt and shorts,
then my knickers, leaving my semi-erect penis free to the air. I loved
the feeling of the air on my dick and balls. It felt so relaxed and

Arundhuti was even faster. She reached to her shoulder, and undid the
tie there, and her sarong fell away, leaving her uniformly brown body
to the air. Her genuine smile showed she loved the feeling as much as
I did. This was the first time I had seen her during the day in
natural light, and she seemed so right there, just nude on the grass,
her pert breasts a little erect in a slightly cool breeze. The same
breeze made the wisp of her pubic hair wave and as it caught my
attention, I hardened to a full erection. She was a beautiful sight!

Arundhuti walked up to me, looked me in the eyes, and as we stood
before each other, grasped my penis in her hand. She just held it
unmoving for a moment, and I could feel my pulse under her hand. Then
she started to move the skin up and down in a manner I was familiar
with in my own time. Apparently satisfied after a moment, she got down
on her knees in the cool grass of the afternoon, and wrapped her lips
around the red, circumcised head, and began to suck on it slowly. I
must confess that my penis going in and out of her mouth was not a
sight I expected to see when I first met the girls some years ago, but
I was beginning to feel that her mother had been repressing a free
spirit that I could easily relate to. I closed my eyes slightly,
enjoying every powerful moment of it. I started wondering that, should
I come, whether she would swallow it all. It was a needless thought,
as she removed her lips with a parting kiss, and stood up. She took my
hand and, with a cheeky grin, took me over to her mother's yoga mat
in the corner of the yard.

She walked ahead and, as she got to the mat, kneeled down on it, and
looked cheekily over her shoulder. On her hands and knees, I could see
her pussy, now puffed up and excited, and that beautiful ass hole above
it. Not one to be slow, I kneeled behind her, and taking my penis in
my hand, slid myself into her so very slowly. I reached the end of my
length, my balls slapping her slightly, and just rested and enjoyed the

I didn't get much chance to enjoy the moment, as Arundhuti began to
move back and forth on her haunches, sliding back on my pole. I put my
hands on her hips, and joined in the motion. My goodness this girl was
tight! I could feel every bump in her vagina on the side of my penis.
I could swear that the tip of my penis was hitting her cervix. I wet
my forefinger, and started to rub my finger against her ass hole. I
received from her a growl of appreciation. I looked to her, and saw
her head was down, covered in hair, just enjoying the moment. Thus
emboldened, I pushed my index finger against the tight opening and
managed to enter her hole up to the first knuckle. I was now plugging
both her holes. We were both so very horny, and I guess we didn't
last too long. I could see that Arundhuti was quickening her pace, and
starting to shake her head slowly from side to side. I too began to do
the same. Being a gentleman, I like to let my partner come first, but
this looked like a close race. Arundhuti pushed back hard against me,
then did so again a couple more times. Then she just stiffened, her
head raised.

I took my cue, and pushed my penis in once, twice more. On the third
thrust I could contain myself no longer. I felt my balls pull
themselves up, and the head of my dick get slightly larger. I spat the
first amount of come into her, and she wriggled a little in
acknowledgment. I pulled out most of my length, then thrust myself in
again, pulsing come as I did so. I was glad I was on my knees, because
my legs would be very wobbly at this moment if I was standing! I
looked down and watched myself go into her once more, her red lips
clear in the afternoon sun. I stayed inside her, feeling the last of
my come go inside. Arundhuti after a moment rolled forward onto the
mat, disengaging me in the process. I looked wryly down at my penis,
now shrunken, red, sticky, and no doubt tired, but I was glad it was up
to the job, especially at my age!

Arundhuti lay back on the mat nude, her nude body taking in the sun's
rays, lying there as if she were on a beach, one leg outstretched, and
her eyes closed to the sun. I could see a light sheen of sweat on her
body. I could not but help also seeing our fluids dribbling out from
between her legs. I'd definitely have to clean that off the mat

Her eyes still closed, Arundhuti said, "Back in India, I was told
that I should behave in a conservative manner, that I should act in a
way that 'good' girls do. I always wanted to just be me. When I
went to the States I found some friends, good people, and basically
normal people. They were the sort of people who were comfortable with
themselves, like I wanted to be. Were were studying our brains out at
College, but these guys were relaxed. I saw them living nude at home
for example, but not displaying themselves. They were just more
relaxed that way. No one made a big deal of it. I gave it a try. I
had some friends over one morning, came out of my room to make coffee
naked, and nobody made any big deal of it. It was so cool!"

"What about sex, " I asked as we got up and began to just wander
around the back yard.

"Nothing really", she said, with a shy grin. "My friends I
accidentally caught at home when I went to visit having sex, basically
all over the place. The needed sex like they needed coffee. No
hang-ups, no big deal. It was done with affection, like friends, but
they just screwed when they needed to. Getting rid of stress like that
helped their grades. Mum, Dad, and just about my whole family was
ringing me up, seeing if I was okay, stuff like that. They meant well,
but it sent me nuts. II found that, if I asked nicely, a flatmate
would just fuck me when we both needed it, get rid of some stress, and
we'd get back to our studies. It was so cool, and no strings
attached. Everyone was so relaxed."

"That's great," I said, feeling a lot closer to Arundhuti as I
understood her better. "Yes, I find it more relaxing to just be
myself, and just say how I feel, and do away with conventional
nonsense. By the way, do you mind if I pee, or shall I go inside?"

"Go right ahead, do it here, please!" Arundhuti replied. " I
actually find this rather fun. I find it kind of stupid that everyone
hides an act that everyone does, you know?"

"Yeah, I know exactly". I walked to the side of the garden, and
being nude already, had little need to muck about with fasteners and
the like. Having just cum, I was in an appropriate floppy state.
Trying to pee with an erection is a real nuisance! I held my penis in
two fingers, as I'd done so, thousands of times before. I felt
Arundhuti's hand come round from behind and duplicate my grip.

"Would you mind it if I held it? I've always wanted to see what
it's like to be able to pint and spray!"

"Go right ahead," I said, rather amused. I watched her as she
moved to my side, fascinated by her simple interest. I obligated her
by relaxing so as to let the pee flow out. On command a heavy stream
of pee began. Arundhuti watched fascinated as it came out, and then
remembered she was in charge. She waved my penis around at first
hesitantly, then with more confidence. Up and down, side to side she
sprayed, getting the fence from time to time.. As my bladder emptied,
the stream began to slow. She looked rather disappointed to see it

"I give it two shakes, right?"

"That's it", I replied. "More than that and you're ... er ..
masturbating me!"

Her laugh tinkled. "Not just now," she promised. "I have to do
something too."

"By all means, go ahead", I invited.

She pointed at some disturbed ground where I had been doing some
gardening. "Do you mind ....?"

Divining her intent, I waved my hand at her in invitation. She
wandered over, scraped out a small hole with the heel of her foot, and
squatted down over it. To be roughly at eye level with her, I sat down
about two metres in front of her and crossed my legs.

As friends, we are able to chat easily. The last couple of days had
added a pleasant aspect to our friendship, and I felt more relaxed with
her, knowing she shared my liberal view of sex and nudity. We talked
about all sorts of things as we sat on the lawn. What I found
intriguing to me was that I completely forgot that I was sitting in
front of her, both of us nude. We were simply two friends chatting in
the back yard. As we talked Arundhuti let out a slow flow of pee, not
all of it in the hole she dug, but that was OK. I watched her pee, and
found that it seemed perfectly normal and natural to me. It seemed
more "normal" I guess for a woman to just be comfortable with a
friend, be accepted for herself nude, without covering herself in
facades. Peeing, being a natural function just seemed right. I find
that hiding the fact that we do so is absurd. She just peed a
beautiful yellow stream as readily as drinking coffee. I watched the
stream of pee slow and then turn to a dribble. I found it interesting
that we didn't acknowledge that she did so, nor feel a need to. We
continued to talk about university studies, and I began to talk about
mine. As I talked, Arundhuti gave me a grin. I wondered why for a
moment, until I noticed he strain her chest muscles a little, and from
between her legs, I could see her begin to shit. I didn't mind as
I'm equally pragmatic about pooping as peeing. In fact, I found it
rather trusting of her, to be so relaxed with me. Thus done, she
brushed some dirt over the poop as if she were simply sweeping the
ground for crumbs. She cleaned herself with some nearby grass, and
continued, not having missed a beat.

As for me, whilst I was comfortable with her peeing and pooping, she
had at all times been squatting in front of me, her bum near the ground
in that manner that has one's knees around shoulder height and the
groin showing between the legs. I could see her beautiful pussy, her
brown skin surrounding such lovely pink pussy lips. No doubt Arundhuti
was oblivious to it, but I was starting to feel familiar stirring in my
own groin! My glance was drawn to her pussy from time to time, as will
any man's no matter how pragmatic he may be about nudity.

I guess my interest in her pussy, and my evident hardon was giving me
away. Arundhuti stood up, stretched a bit, then suddenly pushed me
over out of my crosslegged position, and as I feel back, sat in my lap.
Rather quickly she put my penis inside her, and before I knew it, was
humping me already!.

"One last one before mum gets back?", she laughed.
I could do nothing but acquiesce.

Tale Of Two Hashish Eaters --much better. (-1, Offtopic)

Anonymous Coward | more than 9 years ago | (#11940779)


From 1001 Arabian Nights

There was once, my lord and crown upon my head, a man in a certain city, who was a fisherman by trade and a hashish-eater by occupation. When he had earned his daily wage, he would spend a little of it on food and the rest on a sufficiency of that hilarious herb. He took his hashish three times a day: once in the morning on an empty stomach, once at noon, and once at sundown. Thus he was never lacking in extravagent gaity. Yet he worked hard enough at his fishing, though sometimes in a very extravagent fashion.

On a certain evening, for instance, when he had taken a larger dose of his favorite drug than usual, he lit a tallow candle and sat in front of it, asking himself eager questions and answering with obliging wit. After some hours of this delight, he became aware of the cool silence of the night about him and the clear light of a full moon abouve his head, and exclaimed affably to himself: "Dear friend, the silent streets and the cool of the moon invite us to a walk. Let us go forth, while all the world is in bed and none may mar our solitary exaltation." Speaking in this way to himself, the fisherman left his house and began to walk towards the river; but, as he went, he saw the light of the full moon lying in the roadway and took it to be the water of the river. "My dear old friend the fisherman," he said, "get your line and take the best of the fishing, while your rivals are indoors." So he ran back and fetched his hook and line, and cast into the glittering patch of moonlight on the road.

Soon an enormous dog, tempted by the smell of the bait, swallowed the hook greedily and then, feeling the barb, made desperate efforts to get loose. The fisherman struggled for some time against this enormous fish, but at last he was pulled over and rolled into the moonlight. Even then he would not let go his line, but held on grimly, uttering frightened cries. "Help, help, good Mussulmans!" he shouted. "Help me to secure this mighty fish, for he is dragging me into the deeps! Help, help, good friends, for I am drowning!" The guards of that quarter ran up at the noise and began laughing at the fisherman's antics; but when he yelled: "Allah curse you, O sons of bitches! Is it a time to laugh when I am drowning?" they grew angry and, after giving him a sound beating, dragged him into the presence of the kadi.

At this point Shahrazad saw the approach of morning and discreetly fell silent.


Allah had willed that the kadi should also be addicted to the use of hashish; recognizing that the prisoner was under that jocund influence, he rated the guards soundly and dismissed them. Then he handed over the fisherman to his slaves that they might give him a bed for calm sleep. After a pleasant night and a day given up to the consumption of excellent food, the fisherman was called to the kadi in the evening and received by him like a brother. His host supped with him; and then the two sat opposite the lighted candles and each swallowed enough hashish to destroy a hundred-year-old elephant. When the drug exalted their natural dispositions, they undressed completely and began to dance about, singing and committing a thousand extravagances.

Now it happened that the Sultan and his wazir were walking through the city, disguised as merchants, and heard a strange noise rising from the kadi's house. They entered through the unlatched door and found two naked men, who stopped dancing at their entrance and welcomed them without the least embarrassment. The Sultan sat down to watch his venerable kadi dance again; but when he saw that the other man had a dark and lively zabb, so long that the eye might not carry to the end of it, he whispered in his wazir's startled ear: "As Allah lives, our kadi is not as well hung as his guest!" "What are you whispering about?" cried the fisherman. "I am the Sultan of this city and I order you to watch my dance respectfully, otherwise I will have your head cut off. I am the Sultan, this is my wazir; I hold the whole world like a fish in the palm of my right hand." The Sultan and his wazir realized that they were in the presence of two hashish-eaters, and the wazir, to amuse his master, addressed the fisherman, saying: "How long have you been Sultan, dear master, and can you tell me what has happened to your predecessor?" "I deposed the fellow," answered the fisherman. "I said: 'Go Away!' and he went away."

"Did he not protest?" asked the wazir.

"Not at all," replied the fisherman. "He was delighted to be relased from the burden of kingship. He abdicated with such good grace that I keep him by me as a servant. He is an excellent dancer. When he pines for his throne, I tell him stories. Now I want to piss." So saying, he lifted up his interminable tool and, walking over to the Sultan, seemed to be about to discharge upon him.

"I also want to piss," exclaimed the kadi, and took up the same threatening position in front of the wazir. The two victims shouted with laughter and fled from that house, crying over their shoulders: "God's curse on all hashish-eaters!"

Next morning, that the jest might be complete, the Sultan called the kadi and his guest before him. "O discreet pillar of our law," he said, "I have called you to me because I wish to learn the most convenient manner of pissing. Should one squat and carefully lift the robe, as religion prescribes? Should one stand up, as is the unclean habit of unbelievers? Or should one undress completely and piss against one's friends, as is the custom of two hashish-eaters of my acquaintance?"

Knowing that the Sultan used to walk about the city in disguise, the kadi realized in a flash the identity of his last night's visitors, and fell on his knees, crying: "My lord, my lord, the hashish spake in these indelicacies, not I!"

But the fisherman, who by his careful daily taking of the drug was always under its effect, called somewhat sharply: "And what of it? You are in your palace this morning, we were in our palace last night."

"O sweetest noise in all our kingdom," answered the delighted King, "as we are both Sultans of this city, I think you had better henceforth stay with me in my palace. If you can tell stories, I trust that you will at once sweeten our hearing with a chosen one."

"I will do so gladly, as soon as you have pardoned my wazir," replied the fisherman; so the Sultan bade the kadi rise and sent him back forgiven to his duties.

350m polygons is god damned amazing. I'm sure the kids at Havok will find good ways to implement this, and I'm sure Abit, Biostar, etc will too. I wonder how long it will take for them to make a PCI card you can put in as a graphics-card-booster... or maybe even USB? This technology is extremely exciting. It would definitely lessen the load off of g-cards, and drastically improve the framerate.

I'm no ray-tracing expert, but I think it depends on the approach you take. You can either send out rays from all your lights, and see which ones get to you, or you can send out rays from the screen, and see what light they emanate from. The latter you could have any number of lights, whereas the former you have the same light-limiting problems we have now.

You can't "boost" an existing 3d card with this. It's using an entirely different rendering method, one which happens to have a logarithimic performance curve - i.e. as you add more polys latency flattens out to a constant maximum.

So while it's a bit choppy especially with lighting enabled, you can basically make as complex a scene as you like(within the limits of memory!), and future generations of hardware will only serve to improve that framerate.

Making a 3d engine should be a hell of a lot simpler in ray-tracing too.

Performance (5, Insightful)

MatthewNewberg (519685) | more than 9 years ago | (#11940540)

On the Ray Traced Quake 3 Website it says that runs faster with more computers (about 20 fps@36 GHz in 512x512 with 4xFSAA)

Assuming that is correct,a normal chip can render Ray Traced Quake 3 like graphics at 2 to 3 fps on a 4GHZ machine which means the Ray Tracing Chip could do it at 6 to 9 fps. This might be real-time for alot of research, but when it comes to games anything less then 15 fps is a joke. I'll be interested when they can hit 30 fps, with more graphics complexity then Quake 3.

Re:Performance (2, Informative)

Anonymous Coward | more than 9 years ago | (#11940622)

Dude, way to miss the point entirely. First of all, this is a prototype, not a production model. Second, according to TFA [] , "Nvidia's GeForce 5900FX has 50-times more floating point power and on average more than 100-times more memory bandwidth than required by the prototype." In other words, imagine what this baby can do when backed up by today's graphics technology.

It seems like raytracing would be ridiculously easy to run in parallel. If they're only 90 mhz chips, they probably don't take much power anyways. They should slap 8 of them on a board.

Re:Performance (1)

dj42 (765300) | more than 9 years ago | (#11940781)

Well... it's not quite that easy. It's one thing to make one 90mhz chip. It's a different story to create a system around 8 of them==with hardware and software==to run in parallel. Maybe there is a reason Intel never made an 8x90mhz setup?

Research not meant to be immediately practical (2, Insightful)

Goonie (8651) | more than 9 years ago | (#11940682)

Look, if it was production-ready, it wouldn't be research.

While it's certainly not enough to start playing games, it's a heck of a lot closer than I thought was possible. And there's a lot of tweaking that could be done to speed the process up with present technology. An FPGA [] is the integrated circuit equivalent of a stack of lego. It makes it possible to build custom hardware without forking out for a custom chip; they are however much slower than such a custom-built. I expect if Nvidia decided to make their next-generation chip a raytracer they could get your 30fps. They won't do that for a while yet though - 512x512 is a long way off the resolution gamers currently play in.

But this is interesting, even though it's not practical yet, because it puts the idea on the table that, in the not too distant future, real-time raytracing might well be a possibility. From here, the big graphics-chip makers can start seriously thinking about it, and, maybe about 5 years from now the first hardware raytracers will begin to appear in 3D graphics cards.

Anonymous Coward | more than 9 years ago | (#11940569)

Hopefully, this will help FPGAs to get some much-needed exposure. Their potential is obvious to me, as I think it must be to anyone who's been shown some of what they can do. (For example, this wiki article [] mentions that current FPGAs can achieve speedups of 100-1000 times over RISC CPUs in many applications.)

Every time I hear about the latest beast of a GPU from ATI or NVidia, I can't help thinking what a waste all those transistors are for anything other than gaming, and maybe a couple other applications. We should be putting those resources into an array of runtime-programmable FPGAs! Your computer could reconfigure itself at the hardware level for specific tasks -- one moment a dedicated game console, the next a scientific workstation, etc.

Lest I get too breathless here, does anyone care to inject some reality into this? Are there technological reasons why FPGAs haven't burst into the mainstream yet, or is it something else? Have I misunderstood their potential entirely?


norkakn (102380) | more than 9 years ago | (#11940646)

It takes a while to reconfigure them and there is a relatively small number of rewrite cycles. A lot of algorithms suck on them as well (anything that doesn't reduce cleanly to a few levels of sum of products)

They suck for general purpose work and are more expensive than ASICs for large run chips.

On the other hand, for demoing hardware, low run hardware, or slow but hardware dependent tasks (audio cards, DSP, things that can be done in parallel well), they ROCK

so, they are cool, but they won't replace ASICs

Re:FINALLY (1, Interesting)

PxM (855264) | more than 9 years ago | (#11940663)

They're still Not Good Enough. FPGAs are faster than running software on a normal CPU, but they're still not as fast as running on pure hardware. While modern GPUs are programmable, they're still dependent on extreme hardware which is basically tons of simple circuits doing the same few operations. FPGAs are used when the system has to be more flexible than just 1) get vertex 2) transform 3) paint. Places like ATI do use FPGA systems when they are designing the hardware since it has faster turnaround time from design->test->debug than real hardware. However, these FPGA implementations of GPUs tend to be 1-2 orders of magnitude slower than the final hardware.

xtal (49134) | more than 9 years ago | (#11940666)

Unfortunately the price is an order of magnitude (or two.. or three) too high for FPGAs to really be a consumer tech. The issue I think is an ASIC costs so little in volume, rather than spend all the money on an FPGA design that might be obsoleted next year anyway - a vendor is more likely to commit a design to silicon and then sell that.

There's also the speed issue - I've spent DAYS of CPU time to get a design syntheized from VHDL for a moderately complicated IC built up from available cores.

Factor in optimizing floorplans and the like, and you're talking about serious time commitments to optimize the hardware.

It works; I've been paid to do it in the past; but it's not something I can see in the consumer market for the time being.

An exciting hybrid is intersting though, putting silicon CPU cores on the same die with an FPGA. They've been around for awhile, and I haven't done any FPGA projects in ~18 months - but I haven't seen any real movement outside of areas where FPGAs are already popular.

See Open Cores [] (no, not sores.. :-) ) if you're interested in this - there is open source hardware out there, some really good designs at that.

Re:FINALLY (2, Informative)

captain igor (657633) | more than 9 years ago | (#11940667)

I'm actually on a reconfigurable computing project, which focuses on this, the simple fact is that right now we don't have good methods for generating HDL for a given task, as well as lacking the necessary tools to properly swap tasks into/out of an fpga while maintaining a reasonable communication speed to them. It's being worked on, but it will take time to develop the tools, and even longer before software makers start using them.

Look for a company known as "Quantum" and you'll see all kinds of unimaginable rendering farms. Quantum was using dedicated Pentium III Voodoo2 systems for the ray-tracing hardware on the "Metal" line. Remind you, these are near-commodity hardware with four Obsidian2 graphics adaptors each with four or six 3Dfx Voodoo2 chips on them; count the Voodoo2 and it is up near 16; and the render graphics beautifully! It's the 200SBi graphics adaptors, IIRC. And people still pay no less than US750 for these Pentium III voodoo2 systems and all the realy are paying for is a sticker with cadillac-length customized Voodoo2 hardware. The Government of the District of Columbia (aka U.S. Goverment) currently is moving all Quantum's attention. The FPGA is what will save Homebrew computing and we are all greatful for these FPGA overlords; given that the FPGA design is much more efficient than Quantum systems, and they are mostly free as in speech!

brandido (612020) | more than 9 years ago | (#11940720)

Working with FPGAs, I was quite curious to find out what kind of FPGA they are using - both Xilinx and Altera have some advanced hard functions (such as Multiply Accumulate functions, Block RAM, etc) that seem like they could have a huge impact on the abilities of this board. Unfortunately, after browsing through the links, I had no luck in finding any information about what FPGA they are using. Was anyone able to find this out? Even looking at the pictures of the board, it only shows the bottom side of the board, so it is impossible to see the chip markings!

raytracing with 350 million polygons? (2, Interesting)

Speare (84249) | more than 9 years ago | (#11940730)

Are you sure the Boeing thing was raytracing 350 million polygons? Or just traditional raster pipeline rendering?

See, the reason I ask is, you generally get away from raytracing polygons and raytrace against the actual nurbs or other mathematical surface definitions. That's the point. You don't feed it to simple scan-and-fill raster pipelines.

Wow it rendered the entire Boeing company?! Far out.

Then vs Than (-1, Offtopic)

... 3-5 times faster in raytracing then a Pentium4 CPU...

No, you should have used "than" here. Here are some examples of the proper usage(s) of then and than:

  • I am smarter THAN you.
  • Back THEN, Star Wars was cool.
  • Bunnies are cuter THAN staplers.
  • If you like it so much, why don't you marry it THEN?

Generally, if you think THAN=comparisson, you're okay. Really, it may seem petty, but glaring grammatical errors like this are an immediate turn-off. I read stuff like this and immediately assume the author is a nitwit and don't bother reading further.

Wake me up when they introduce a 3D Radiosity Chip.

Anti-Planet (5, Interesting)

Anti-Planet Screenshots [] . Anti-Planet is a FPS rendered entirely using ray tracing. It requires an SSE compatible processor (PIII and above. AMD only recently implemented SSE in their processors). This has been out long before Doom 3 and runs on systems Doom 3 couldn't possibly run on and the graphics tricks it does are just now being put into raster graphics based games.

That, along with Wolf 5k [] inspired me to start working with software rendering. I think ray tracing will eventually be the way real time graphics are rendered in order to keep upping the bar for realism.

Real Time Software Rendering []

I'm working on tutorials covering software rendering topics. The tutorials start by deobfuscating and fully documenting Wolf5K, cover some basic ray tracing and are now going through raster graphics since the concepts used for raster graphics apply for ray tracing as well. I'll be returning to do more advanced ray tracing stuff later. The tutorials also cover an enhanced version of Wolf5K [] written in C++ that is true color and has no texture size limitations.
