In Rhinocommon I can use this funtion : Intersection.MeshRay Method (Mesh, Ray3d,Int32), find the faces which intersect with the Ray, but I search the Rhino c++ sdk along time, I was not found the funtion like it, how cant I solve it?
ON_RayShooter class. See opennurbs_plus.h for it’s declaration.
I have see it, in ON_RayShooter class, just have the funtion abaut surface.
So I must change the mesh to surface first?
Let me know if this sample code helps.
