If you weren’t already aware, it will probably come as no surprise to hear that the pioneering computer-animation studio Pixar built its early workflow on Silicon Graphics SGI workstations. These were beefy Unix machines that, as the name implied, were developed for graphical work. When the age of the RISC workstation came to a close, many Unix users were pushed onto Windows NT — but not at Pixar. At Pixar, they learned to love the penquin.
It comes down to hardware rather than software. You know the story: PCs got faster and cheaper with different vendors competing for a giant market, while the world of RISC workstations couldn’t keep its lead. Pixar would have been happy staying on Unix workstations, even SGIs if that had been a practical option — but with every project increasing the load on the render farms, it wasn’t. Yet Pixar’s entire workflow was predicated on a Unix environment. They had written a couple million lines of code for their internal use, and really didn’t want to port it over to Windows, even after a mistaken rm command nearly cost the world Toy Story 2.
The path of least resistance would be to port to something more similar to IRIS’s Unix environment, something POSIX compliant. That path led Linux, and by 2001, the port was done. By 2003, a new render farm using Xenon processors brought the whole studio to Linux and x86, which has since become an industry standard.
We’re left with only two questions: one, why didn’t more industries — like the CAD/CAM world — that were also reliant on Unix Workstations follow Pixar and Hollywood onto Linux, and two, why did Pixar go with Linux instead of some variety of BSD? [Crierlon] doesn’t address either question, but we’re betting some of you might have an idea. Let us know in the comments if you have the inside scoop; inquiring minds want to know!
