Hi. For example, i have TopoDS_Shape and i have my own 3D engine on OpenGL. I need pure faces data, to put it into the VertexBuffer on GPU and draw it via OpenGl. (i don't use cascade viewer) I need:
1. Triangles collection of 3D model
2. 3 vertices data per each triangle (each triangle have 3 points :-) ) in absolute world coords
3. Normal vector to face for each vertex
4. good, if i will have UVs coords too :-)
So, guys, how to get pure vertices data?
