I create a truncated plane in my code:
Handle(Geom_Plane) geomPlane = makePlane.Value();
TopoDS_Shape aPlaneShape = BRepBuilderAPI_MakeFace(geomPlane,
0, width, 0, height );
After all view transformation (move, zoom, rotate) I want to get coordinate of visible area on my truncated plane (projection of my plane on the screen plane). I think this area can be defined by four 3D points.
Please, help me!
Thanks in advance, Damir
