Disney Animation also posts its papers online: http://www.disneyanimation.com/library/list.html

I can't find similar pages for PDI/Dreamworks or Blue Sky.

If this stuff interests you, check out the SIGGRAPH 2011 papers: http://kesen.realtimerendering.com/sig2011.html

Ptex is awesome! Any chance Disney's hair tools will get open sourced?
