I havn't looked at the code yet. Just a comment after working with the savage driver: I was under the impression that Mesa does all clipping. If a primitive is clipped it will call the driver's clipped polygon callback function to render it. The savage driver has a savageClippedPoly function which is hooked up as tnl->Driver.Render.ClippedPolygon in savage savageChooseRenderState. See savagetris.c. I could imagine that the cle266 driver just didn't specify a polygon function so it falls back to software. > > Alan > Felix ------------ __\|/__ ___ ___ ------------------------- Felix ___\_e -_/___/ __\___/ __\_____ You can do anything, Kühling (_____\Ä/____/ /_____/ /________) just not everything [EMAIL PROTECTED] \___/ \___/ U at the same time. ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
