WebMay 8, 2016 · This is a special scene-graph node that utilizes a user specified program to select which child a ray should traverse and which not. #include rtDeclareVariable (unsigned int, timestep, , ); RT_PROGRAM void animation_selector () { rtIntersectChild (timestep); } This is a simple version of such a selection program. WebProper creation of Optix 7.1 TLAS Instance Acceleration Structure. I am trying to figure out how to build a TLAS properly. Using the samples that came with OptiX 7.1 and Ingo Wald's Optix 7 samples, started with a triangle (just the BLAS that holds the geometry) and it works fine (moved the triangle sample of the SDK to Wald's example framework).
