Linux goes to Hollywood
j2brown writes: " Yahoo! News has this little article about IBM taking Linux to Hollywood. " It's not a very in-depth article, but it is interesting that Big Blue is saying that Hollywood will be moving their rendering stuffs to Linux in the next 12 to 18 months. Wonder how SGI feels about that.
I am not sure exactly what you are refuting. I know that PRman is used for almost all CG in films with BMRT and Mental Ray filling in a few gaps here and there. Not all studios are working for film however.
I never said that PRman was new to linux.
Maya, SI, 3DS, LW, and Houdini are the serious 3D programs out there. They are the complete, commercial, 3D packages used for production work 95% of the time. Cinema 4D might be there too someday. Axis, being shown at siggraph was done entirely with 3DS. All of Blizzard's animation is done with 3DS. Those five programs are what people buy when they are in a production environment. I realize that there are many side programs that have special uses.
You are refuting statements that I have not made, so please, get a clue.

Um, changing to Linux for rendering in 12-18 months?? What rock has IBM been under? Visual Effects house have been using Linux rendering already for the past 12-18 months. Final Fantasy was rendered on a 1200 CPU Linux render farm (see the recent Ars Technica article can't be bothered to find a link).
7 4 ), sure other hollywood houses have them as well.
Lord of the Rings has at least several hundred CPU linux render farm of SGI 1200 boxes(see here: http://www.theonering.net/perl/newsview/8/9889828
SGI doesn't care because they sell a lot of rack mount linux intel render servers. The real next wave of adoption of Linux in visual effects is as 3d and compositing workstations. Maya, Shake, Rayz, Houdini all run fine on Linux with the right 3d card. The only reason Linux boxes don't dominate in Visual Effects is that high bandwidth playback eg playing 2k images in realtime of a disk array is not really possible under Linux. That's why they still have a ton of SGI octanes kicking around.
This is a pretty big issue so I feel I should run down some of the more important points.
First, yes, SGI offered Linux systems a long time ago and to my knowledge they have done very poorly. They were however for workstations and not rendering, as IBM's newest offerings seem to be. IBM is probably going into workstations too, but that isn't what the article is about. Many big companies with Big Money (TM) have invested a whole ass ton in SGI clusters over the years, from Onyx computers for compositing and play back, to Octanes for creation, to Origin's for processing job queues.
Everyone is switching to Linux. PC's are so cheap and close to what SGI has to offer that it stands out as a clear solution. Pentium 4's and Athalon 4's are including more features suitable to rendering. SIMD instructions are great stuff for all the vector math that goes on behind the scenes. Linux costs nothing so when you have 1000 computers in your render farm you aren't paying $200,000 in licenses every few years. It is stable so that also helps everything, especially rendering. When a frame takes 8 hours to render, you don't want to worry about the OS crashing 6 hours through. You have 1000 computers and if they don't all work smoothly you are fucked. Lastly, Linux is unix, and that's important for an industry coming off of other unix platforms, mainly Irix.
Software for Linux is Good Stuff (TM) in the graphics world. As far as rendering goes, you have the mighty PRman, Mental Ray, Blue Moon Rendering Tools, Jig, Entropy, and many other renderers. That's good enough for just about any studio. On the software front, you have the magic four (or five, depending on how you look at it) of Maya 4 , Softimage XSI 2.0, 3D Studio 4, Lightwave 6.5, and Houdini. Maya and Houdini run on Linux right now and can be purchased for a small (huge) fee. Lightwave is the most ported 3D application that I know of and runs on Amiga (earlier versions), Windows NT, Sun OS, Solaris, Mac OS, Mac OS X, and Irix. It shouldn't be a huge deal to port to Linux. 3D Studio is another story. It has a deep history of being rooted in WinNT, and didn't even run on NT for Alpha when Alphas were all the rage so only time will tell. Also compositing software like Shake is making its way as well.
Last on the list is custom software. Pacific Data Images (Antz, Shrek) has written lots of software for Linux and ported lots from Irix as well. Linux is unix of course and that means that all the custom software that no one wanted to port from Irix to NT is now being ported to Linux with ease, and that's a huge deal.
There aren't too many Free solutions in there, I realize, but Linux can't be everything to everyone and remain completely Free. I am sure there is a lot of GIMP action going on there but not many programs in the Free world are powerful enough to help out the big studios.
I hope that clears some stuff up!

Radiance comes immediately to mind for open source. Not-so-open source programs like Blender and BMRT are also good.
SGI was the first major company to offer Linux with their systems. Also, I heard from a co-worker that SGI is working on an Itanium-based cluster (64x64)... probably for a redering farm. I don't have any URLs for this, however.
I think if IBM plans to "penetrate" the rendering market, they will have to compete with SGI still. Not because of the O/S (since they will both run Linux), but the fact that SGI has always had superior I/O and bus speeds compared to most other machines. The first x86-based SGI machines used Intel Xeon processors, but they redesigned the I/O. They were able to get a 50% performance increase from the system by tweaking the I/O.
Already Alias|Wavefront has ported Maya (their flagship 3D software and the most commonly used package for movie animation) to Linux. The Pixar Renderman rendering engine is already ported to Linux. Basically, everything a studio would need is already ported to Linux. Softimage also has ported their software to Linux as well.
In other words, IBM is *way* behind the curve on this... Linux is already an integral part of 3D animation, and with the release of Maya 4 and it's Linux port, this trend is definately going to continue. Using off-the-shelf, inexpensive hardware for both workstations and render farms makes a lot of sense, and Linux is perfect as an extensible UNIX-based OS for animation purposes.
