What's the best way to implement screen selection (e.g. a rectangular region) of shapes? I have a path and a vector, defining the area selected and the view Z direction, and I want to determine if a given solid, face, edge, or vertex falls into this region.
Creating a solid from the path and vector and then doing BRepAlgoAPI_Common seems a bit heavyweight but has the advantage that it could be used with perspective transforms also.
Triangulate the shape and then check for polygonal prism / triangle intersections?
