The Pixar online library is a really great resource.

They have some pretty cool papers on there, but the few landmark papers that Pixar published were all published in the 80s.

Here is a better source for papers (SIGGRAPH, Eurographics and EGSR have the best papers on rendering):

The Hyperion renderer was made by Disney, not Pixar by the way. Pixar only uses their own RenderMan renderer. Disney uses a mix of Hyperion and RenderMan, as Hyperion is not useable for test renders, as it can take up to 15 minutes until a pixel will appear on the screen, as they trace millions of rays at the same time.

"Disney uses a mix of Hyperion and RenderMan, as Hyperion is not useable for test renders, as it can take up to 15 minutes until a pixel will appear on the screen, as they trace millions of rays at the same time."

None of the things you claim in this sentence are true. Disney does not use PRman at all anymore.

Sorry, I guess what I meant was that Hyperion is perfectly capable of being used in test renders. The amount of time before you see any resolved pixels is of course dependent on the size of your scene, the desired resolution, etc. It could take 15 minutes before a pixel shows up, but that's not a standard case for production test renders in an artist's daily work.
