OptiX Advanced Samples
This is a set of advanced samples for the NVIDIA OptiX Ray Tracing Engine. They assume some previous experience with OptiX and physically based rendering, unlike the basic tutorial-style samples in the SDK directory of the OptiX 4.0 distribution. They also use some different libraries than the SDK samples; GLFW and imgui in place of GLUT, for example. This means you cannot generally copy one of the advanced samples directly into the SDK, and vice versa.
Please navigate into the optixIntroduction sub-folder for specific documentation of the new tutorial examples contained inside that.
Technical support is available on NVIDIA's Developer Zone, or you can create a git issue.
