FWIW, my resistors were shaded with a crude Blinn-Phong pixel shader. (Simplified by having the viewer and light at infinity). (I think!) That was basically what fell out of me doing bump mapping, albeit very inefficiently. I probably ought to use the vertex shader to compute the texture space basis vectors rather than CPU. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
