Indeed. It’s not a hard project, algorithmically speaking, but nobody has yet put forth a quality proposal to work this area. > So, according to the description there, BoT has a raytracing routine that, > when finds an "in" point for a ray, due to extremely thin surface, assigns > the "out" point as the "in" point + the implicit thickness added to each > coordinate of "in" point and I would have to implement the same methodology > for NURBS surfaces now. > > To analyze the problems that I would face in implementing the plate mode > raytracing for NURBS, I would have to understand exactly how raytracing NURBS > works.

But you don’t really need to understand it. You need to understand what plate-mode means — and more specifically you need to understand BRL-CAD’s existing plate-mode implementation for triangle meshes. If you understand that, you’ll know exactly what is needed for NURBS plate mode, even without understanding NURBS ray tracing. This requires a lot of reading of code and playing with sample geometry.
