Hi all I am using "3D boolean operations on nef polyhedra".I have a model with
Vertexs,Indexs and Texture coordinates. I intersect the model and a sphere,
and I could have some Vertexs and Indexs as result by using
"Nef_Polyhedron". The problem is how can i get the Texture coordinates after the
The texture is something you added yourself to the vertices, there is no
way Nef_polyhedron can guess how to set it automatically for new
vertices.

However, you could add a default value when the texture is not set, that
way you can detect vertices created by the intersection. Then you can
set the texture coordinates by hand to those vertices.

intersection on the model.
My English is not good Thanks very much!
