Hello, I am working on a mesh generation algorithm based on BRL-CAD. As geometry interface I intend to use the ray-tracing functionality. From any point in space I would like to shoot a ray in a given direction and get the first intersection with the surface of the volume. The original point could be inside or outside of the volume. Unfortunately rt_shootray will also return intersections with internal shapes which have been used to create the volume (boolean tree). Is there a way to specify that I do not want this? Or do I have to shoot another ray in the same direction and check if it re-enters with zero distance?
