I took some time to create a diagram that attempts to give a high level explanation of the Graph Nodes used in NVIDIA OptiX. I was fairly confused by the different nodes and their purposes when first programming in OptiX. So I’ve created this diagram with the goal of hopefully helping new OptiX programmers understand what the different nodes do.
If anyone has a suggestion or correction, please let me know, and I will make the change.
All information in these diagrams come from the NVIDIA OptiX 5.0 Programming Guide.
