Given a 3D point Pt and a face aFace, I'd like to check whether Pt lies inside aFace. I have tried to use the BRepClass_FaceClassifier, but it seems that it doesn't work well since it always return a state "1". Could anyone give me some hints?
Actually, the problem serves for another problem that is to determine whether an angle on a face is convex or not. Any suggestions?
Thanks a lot.
