hoknamahn Posted August 14, 2007 Share Posted August 14, 2007 Hey guys, Any ideas how to trace geometry from point P along the normal N using HDK? Are there some functions to do it? Quote Link to comment Share on other sites More sharing options...
edward Posted August 14, 2007 Share Posted August 14, 2007 Are you trying to do ray marching or some sort of ray intersection? You question doesn't really make sense without more context. Quote Link to comment Share on other sites More sharing options...

You question doesn't really make sense without more context. Okay. I want to calculate a distance between current point of geometry and intersection of ray projected from this point along the normal with geometry (same as we can do with Ray SOP/Point Intersection Distance) I see a bunch of GU_Ray* Edited August 15, 2007 by hoknamahn Quote Link to comment Share on other sites More sharing options...
