Might the caching be fed back into non-OpenGL versions in a way that several of the HID variants could benefit from it? > I'm not sure how any of these different approaches stand with the > possibility of anti-aliased geometry, but I find it absence less of a > visual problem than in gschem.

I think you just need glEnable(GL_POLYGON_SMOOTH); However, glHint(GL_POLYGON_SMOOTH_HINT, [GL_FASTEST, GL_NICEST, or GL_DONT_CARE]); may also be helpful. And there may be some driver override in effect. At least, I think I've seen that in the Windows control panels, so I don't know if that means there would be also Xorg settings to override software choices in this area. _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
