Building an Orthonormal Basis, Revisited Tom Duff, James Burgess, Per Christensen, Christophe Hery, Andrew Kensler, Max Liani, Ryusuke Villemin March 2017 Frisvad [2012b] describes a widely-used computational method for augmenting a given single unit vector with two other vectors to produce an orthonormal frame in three dimensions, a useful operation for any physically based renderer. The implementation has a precision problem: as the z component of the input vector approaches -1, floating point cancellation causes ... more Paper (PDF) |

RenderMan XPU: A Hybrid CPU+GPU Renderer for Interactive and Final-Frame Rendering Per Christensen, Julian Fong, Charlie Kilpatrick, Francisco Gonzalez, Srinath Ravichandran, Akshay Shah, Ethan Jaszewski, Stephen Friedman, James Burgess, Trina M. Roy, Tom Nettleship, Meghana Seshadri, Susan Salituro June 2025 RenderMan XPU is a rewrite of Pixar's RenderMan renderer, designed to run on both CPUs and GPUs. Like its predecessor, it is a progressive path tracer, suitable for both interactive previews and high-quality final-frame rendering, but it utilizes modern hardware and software techniques to run significantly faster.
