What I'm trying to do is much simpler than rendering a 3D object.. All I'm trying to do is display a 3D line drawing or wireframe on the screen. I don't need it to dynamically rotate or anything, and it doesn't need to show any surfaces, textures, lighting, reflections, or shadows, just give a representation of the XYZ points and lines connecting 2 pair of XYZ coordinates on the screen. The purpose of this is to show a 3D representation of a CNC tool path including the Z movements.
