My question is:
Is there a way to retrieve the coordinates of a vertex after translations or rotation?
Example: x = 10, y = 10, z = -2
After a calls to glRotate(45,0,1,1) how can I know the actual status of x, y and z?
In older versions of OpenGL: feedback mode (glRenderMode(GL_FEEDBACK)).

If you're only doing this for a small number of vertices (rather than entire meshes), you're probably better off just performing your own matrix arithmetic in the application.
