Ironically Renderman has had global illumination and ray tracing for over ten years. Having said that, what renderman is and what pixar animation do/use are rather orthogonal. For example pixar made heavy use of Subsurface scattering in the incredibles. Something that was at the time rather time intensive. The title is a bit misleading as they've been using raytracing for years 1 [1]http://graphics.pixar.com/library/RayTracingCars/paper.pdf http://graphics.pixar.com/library/RayTracingCars/paper.pdf
