OptiX is a software development kit for achieving optimal ray tracing performance on the GPU. It provides a simple and flexible framework for accelerating ray tracing algorithms much like rasterization APIs such as OpenGL.
OptiX has been in active development since 2008 and has been successfully deployed in both commercial applications such as Adobe After Effects and Ansys as well as in-house development in applications ranging from film rendering to scientific visualization (including Gordon Bell Award finalists), defense applications, audio synthesis, and computing lightmaps for games.

Pixar’s Real-Time Previewer (RTP) is an internal tool based on OptiX. This tool enables lighting design and look development much faster than prior tools. It uses a full global illumination renderer with progressive refinement while the artist makes changes.
Visual Molecular Dynamics (VMD) is a molecular visualization program for displaying, animating, and analyzing large biomolecular systems using 3-D graphics and built-in scripting. VMD’s preferred rendering mode for both viewport and final render is OptiX, with full VCA support available. The OptiX path renders the highest visual quality and even has a frame rate five times higher than OpenGL on massive datasets.
