Lucas Digital Releases OpenEXR Format

frankie writes "Although George Lucas may have gone over to the dark side, at least some of his staff prefer Freedom and light. ILM has released OpenEXR, a graphics file format and related utilities, under a BSD-style license. Among other things, it supports the same 16 bit format used by Nvidia CG and the Geforce FX. OpenEXR runs on Linux, Jaguar, and Irix; other platforms are likely to work with a little help from the community."

Now I can render... (4, Funny)

Jar Jar in my own home! Thanks Lucasfilm!

Rendering a movie of Gollum choking Jar-Jar to death, I'd pay to see that.

Didn't you mean to say "rend" rather than "render"?

No, he means render. As in: "This horse will soon be rendered into glue."

Of course, why simply tear him in half when you can finally make something useful out of him. Can we then use the glue to seal Anakin's mouth shut? Yippee!

Re:Now I can render... (1)

uberdave (526529) | more than 11 years ago | (#5138801)

I found the scene where Jar-Jar was beating the snot out of one of the battle droids to be quite hilarious. Not to mention the scene of the Jawa Sandcrawler holding its own in the pod race. (FYI: These are on the supplemental DVD, not in the movie.)

Re:Now I can render... (1)

aborchers (471342) | more than 11 years ago | (#5138908)

Honestly, I never had the big problem w/ Jar Jar that so many /.ers did. I just couldn't resist the joke.

But I stand by my desire expressed down-thread to glue Anakin's mouth shut...

SCO Group Hires Boies After All
Posted by timothy on Wednesday January 22, @01:57PM
from the mendacity-mendacity-mendacity dept.
pitr256 writes "So it seems the SCO Group has decided to hire infamous Anti-Microsoft lawyer David Boies after all. This comes upon reversal of the SCO Group statement according to Chief Executive Darl McBride of having not engaged Mr. Boies to take legal action against our fellow Linux vendors. Now, CNet News is reporting that not only is SCO Group investigating the Linux vendors but that it is also going to investigate Windows, Mac OS X, and the BSD derivatives. So if your technology can't win on price and performance, break out the lawyers and sue everyone. Does anyone else see this as the end of SCO (Caldera) like I do? I certainly will never use anything from them ever again."

Interviews: Ask a LinuxWorld Exhibitor
Posted by Roblimo on Wednesday January 22, @11:15AM
from the your-representative-at-the-show dept.
Most Slashdot readers aren't coming to the LinuxWorld Conference and Expo in New York this week. If you're not coming, but you have a question you'd like to ask one of the exhibitors, please post it here. I promise to ask 10 of the highest-moderated exhibitor questions on your behalf, and I'll do my best to ask more than 10, time permitting. If you have a question for anyone who is holding a conference session or tutorial Thursday or Friday, please feel free to post it, too. I will try to ask speakers at least a few questions, but that's chancier than getting hold of exhibitors (who are in booths where they're easy to find), so no promises. One question per post, please. Hopefully, I'll have time to type up the answers over the weekend and post them Monday or Tuesday.

Microsoft Loses Showdown in Houston

from the shut-up-jerry-carter dept.
An anonymous reader writes "It seems the city of Houston has decided against using Microsoft software. It really is amazing how much it costs to use (and maintain) software. I can't help but wonder if this will become a trend." Turns out they decided on the relativly unknown SimDesk suite, which has nothing to do with The Sims, sadly. Many, many posts about this. In additional news seldo writes "There's an interesting interview on News.Com with Peter Houston. He discusses Microsoft's changing attitude in competing with Linux -- no longer calling it a "cancer" but instead promoting the advantages of Windows."

And I would doubt he played any role whatsoever in the decision.

But its great that now we can all remaster his original films and add our own awkward, out-of-place looking robots, aliens and spaceships.

Re:ILM isn't Lucas (5, Informative)

dhess (65762) | more than 11 years ago | (#5138342)

Actually, he did, since this is the first time that ILM or any other Lucas Digital company has released source code for free.

It was a group of developers who first floated the idea, but ultimately it was George's call whether or not to do it, and he gave the OK, which is pretty cool, I think.

Lucas controls all (2, Interesting)

McSpew (316871) | more than 11 years ago | (#5138862)

I saw a rare interview/profile of Lucas just before AOTC was released, and they pointed out that Lucas is intimately involved in the important decisions for all of his businesses (and he has lots of them). While he might allow small decisions to be made by subordinates, Lucas pretty much nearly micromanages his empire. Can't argue with his management style because it's clearly worked for him. Come to think of it, I wonder if the folks at Pixar would have preferred to stay with Lucas vs. going to work for Steve "Reality Distortion Field" Jobs.

Amsterdam Vallon (639622) | more than 11 years ago | (#5138317)

Nice, it's wonderful to see that Lucas and his company have read up on, understood, and embraced the Open Source market. For those who don't remember, they pretty much set the gold standard in the movie industry, and we still live with the benefits today. But while this sounds like a good idea at first for us geeks, I have to wonder about some of the choices made in the design of this new format.

Linux is specifically written for the desktop market these days anyway, which is why Lucasfilm probably decided to go cross-platform on us.

It's a good idea, don't get me wrong. But, I'd like to see them take a more sensible approach in the future and consider which platform dominates home users and not which feels best in their hearts.

Their hearts will heal with more money, not with little to no business from Linux users, all of whom tend to spend less than $10 a year on computer software.

jj_johny (626460) | more than 11 years ago | (#5138320)

Get it folks. They designed a format and have some tools but have decided that they want to tap into the great pool of OSS talent. Who says this is not a dark side ploy?

If all goes as planned all the great OSS software will be written to output this format in no time.

BFaucet (635036) | more than 11 years ago | (#5138480)

Who cares?

This means everyone (including you, me, and yes ILM) can benefit from this.

The thing I'd be suspisious (sp?) of is them releasing this format so everyone will start using it, then releasing their tools (for gobs of cash) that'll be better than most other software using the format.

Re:So they would like you to write tools for them (5, Insightful)

JanneM (7445) | more than 11 years ago | (#5138519)

Um, to me that sounds like a good plan for everyone. It's one of the points of open source that while you release your stuff, you can make money on your own extensive knowledge of said stuff. After all, since the format and basic tools are open you do not need to use their (hypothetical) proprietary versions if you do not want to.

Re:So they would like you to write tools for them (1)

kevlar (13509) | more than 11 years ago | (#5138985)

Re:So they would like you to write tools for them (1)

Dr_Marvin_Monroe (550052) | more than 11 years ago | (#5138778)

Yeah,

I'm not sure where the problem is either...I'm alright with "open" all the way to the graphic card mfg's format.

If that means the card makers will produce something that levels the playing field on drivers for all OS's, count me in. I would also be suspicious of "special tools"....but that could only happen if the spec. for the drivers is not really "open."

Perhaps I don't really understand the problem though...how is getting the OS community to write/enhance/extend/propagate a format that would be great for all of us a problem?

Re:So they would like you to write tools for them (5, Funny)

fritter (27792) | more than 11 years ago | (#5138504)

If all goes as planned all the great OSS software will be written to output this format in no time.

Actually, if all goes as planned in six and a half years there will be great OSS software at Milestone 15 able to render a sphere in only ten hours.

Re:So they would like you to write tools for them (2, Interesting)

womprat (154589) | more than 11 years ago | (#5138520)

So? They create a format which open source tools can use. We get a standard format and all the tools. And they also get the free tools.

Geez I didn't realize Dale Gribble frequented Slashdot.

There's a very simple reason why Lucas would release this format to the world: So it'll get included in other commercial packages. If Gimp, FilmGimp, and eventually Photoshop start supporting this format, then it's a win for everybody. This "They're doing it for greed!" paranoia is ignorant. Of course they're doing it for their benefit, they're paying for it by making it benefit everybody else. Damn them!

That's a bummer. Lightwave loves HDRI imagery.

Out of curiosity, has anybody used HDRI images for textures? I'm curious if the floating point data makes a difference. I could see it being particularly useful for the diffuse and lumination channels. What about color?

I'm sure somebody will port it to Windows in time. The libraries themselves are pretty vanilla code, so it should be easy to port. We don't really use Windows for effects work here so it hasn't been a priority for us.

"Out of curiosity, has anybody used HDRI images for textures? I'm curious if the floating point data makes a difference. I could see it being particularly useful for the diffuse and lumination channels. What about color?"

Okay, somebody modded me down as 'Off-Topic'. I'm just going to assume he/she/but probably he didn't understand what I was talking about here.

OpenEXR is a format for High Dynamic Range Imagery. What this essentially means is that instead of describing a pixel by having 3 channels @ 8-bits per channel (which has a maximum value of 255), you get a floating point 16-bit value per channel which is a measure of intensity. The result? Instead of having just color data there, you have color data & intensity data. The sky's blue, right? If you take a 24-bit picture of the sky, you get blue pixels. Is that enough data? No. Try looking up at the sky without squinting your eyes. Can't do it, can ya? The sky is *very* bright. With the HDRI format, you can store that luminosity as well as the color. That's why they use it for global illumination. You're capturing light sources, intensities, and color at the same time.

Thing is though, a floating point format has uses in other areas of 3D such as texture mapping. It means you can create/capture textures that deal in intensity as well (just like real life), thus you get a much more realistic response from lights in the scene.

I have no idea if I'm making any sense here or not, but the main point I'm trying to make here is that I am nowhere near off-topic. That's the reaason this format is interesting. It's not another .PNG or .JPG format, it's a more accurate way of storing information about light, and us people that work in 3D have a lot to be excited about. Since it's just recently become involved in the major 3D Apps out there, the capabilities of it are still in their infancy and I'm curious what people have discovered about it.

They just openly defined the file format, not the tools to create graphics.

This is a nice thing for them to do since they did have to put time and money to come up with this format standard. However, it's not that much of a charitible contribution to the software community. They had to come up with this format anyway, so why not release it to everyone?

qwijibrumm (559350) | more than 11 years ago | (#5138573)

From the site:
ILM has released OpenEXR as free software. The OpenEXR software distribution includes:
* IlmImf, a library that reads and writes OpenEXR images.
* Half, a C++ class for manipulating half values as if they were a built-in C++ datatype.
* Imath, a math library with support for matrices, 2d- and 3d-transformations, solvers for linear/quadratic/cubic equations, and more.
* exrdisplay, a sample application for viewing OpenEXR images on a display at various exposure settings.
The OpenEXR software distribution is now licensed under the modified BSD license, available here.
I would call the software they released under a BSD type license "tools to create graphics." Your milage may vary.

Re:Ummm. Wrong. (0)

Anonymous Coward | more than 11 years ago | (#5138823)

Mixed bag. The OpenEXR stuff listed is really just sample code, of the sort that generally goes along with any publically specified format. "Half" and "Imath" either provide support that's specifically useful for OpenEXR, or they were just tossed in (more likely the former). It's akin to the JPEG or MP3 reference code.

It's nice that they used the BSD licence, but it's not really that big a story. Hopefully they don't retain patents relevant to the format (a la MP3).

This is, hands down, the worst exploitation of labor and intelligence I may ever see.

Lucasfilm needs to write a lot of code and make some serious software in the very near future, so they make what they're tricking us into thinking is a grand gesture. What many of you don't realize, and what I didn't at first realize, is that this is a blatant ploy at extorting labor out of us by creating Open Source filters and conversion utilities which will then, upon completion and after some testing, be renamed as Lucasfilm software programs and then used to help George Lucas buy a few more houses and make a few more crappy movies.

It's bad enough that Lucas has taken a back seat to Spielberg in terms of film earnings and film quality, but now that he's using his own fans for free labor, I don't think I'll bother lining his pockets with more cash after a disrespectful act such as this.

I know that this is supposed to be some sort of goofy pro-Linux anti-MS troll, but I dont get it.. It's just incoherent. Are you saying that coders who use Windows are just too stupid to do it?

Anyways, if you'd RTFA, you'd notice that it simply doesnt compile natively under windows, but should be easily enough compiled against cygwin.

It's more than likely just a handful of ioctl() based disk routines that need to be translated to make it a C shared lib, and a tad of restructuring/jumptable management to make it a COM object or library style DLL.

Really not a big deal at all. Being a hotshot Linux hacker yourself, you'd already know that.

Before you spend a half-hour downloading any packages, please note that shared libraries aren't supported yet for Mac OS X version 10.2.

Well, to rephrase this, you can build them, but Lucasfilm have't gotten them to link due to undefined symbols and are probably
doing something wrong in the Makefile system.

The test suite will automatically try to link shared libraries if you've built them, so 'make check' will fail. To run the confidence tests, tell configure not to build shared libraries ("./configure --enable-shared=no").

NanoGator (522640) | more than 11 years ago | (#5138473)

Hey dudes,

I was just curious if anybody out there uses HDR imagery (like the OpenEXR format) for anything besides global illumination?

I've been fiddling with the .HDR format (similar to OpenEXR, I imagine) in Lightwave's various texture channels and have gotten interesting results. (Especially the diffuse channel.) It strikes me that you could lose the diffuse channel all together in favor of a floating point color channel. In english, that means that you have one texture that responds properly to light, as opposed to having to assign the color of the surface in one channel and it's light reflectance in a seperate one.

That's seriously cool, but I'm in my infancy here with regards to these floating point formats. I'm just curious, who's using HDR in ways besides global lighting? It seems like there's a whole new door opening here.

Don't hold back, tell us what you really think.

This might come as a shock to some, but the entire world isn't the same as you. They have different needs and different desires. In this case, ILM has a need for an image format which allows for high dynamic range and lossy compression. PNG doesn't supply that. TIFF doesn't supply that. JPG doesn't supply that. So they invented their own, and released it for all to use.

They really don't care very much about whether your browser supports it (although a nice plugin would be a cool idea, and golly, it is possible because they were kind enough to release the source). They are busy making movies. If you aren't making movies or interested in high dynamic range photography, you probably don't care. But then, they never said you had to care, did they?

the only thing I see this library even offers is the 'capability to store' HDR' (High Definition Rendering) information, which offers better lighting techniques and edge detection.. *free* code to do the exact same thing is available at ATI, nVidia, SIGGRAPH, Usenet, any number of graphic books, etc.

It doesn't look like it's tiled (4, Informative)

exp(pi*sqrt(163)) (613870) | more than 11 years ago | (#5138775)

Movie making required heavy duty image processing. Often thousands of layers need to be processed together with very complex operations. In order to do this at film res you need to break the image up into tiles. A package like Apple's shake works with 128x128 or 256x256 tiles I can't remember exactly. For maximum efficiency the image files need to be stored as tiles too. So popular file formats used such as Kodak's DPX/Cineon or TIFF support tiling. Without tiling you end up with major cache thrashing as the entire image needs to be read in any time a single tile gets dropped from the cache. (I'm talking about the application cache - not the CPU or memory cache.) Even if you do low quality work at low res (eg. ILM do much of their work at hi def resolution) you can still suffer from this.

It's not a show-stopper but tiling really ought to be there. This format doesn't really add much to already existing formats and subtracts something important.
