I think so. You have much more vertexes than first person shooters in a
modeler. Rendering the wireframe of the chess2.pov example takes half a
second on my TNT 2 and a 433 celeron with a perspective camera.
And the perspective camera uses only simple transformations.
I think calling trigonometrical functions for each vertex would be far too
slow (didn't tested it yet)
