Darn, I see it now. Okay, would you mind telling me if the following assumption is incorrect: The ClipAndMask is used to check for the special case where we guarantee that all triangles will be discarded because of clipping. It simply allows us to short-circuit out of the pipeline in this case. I can get away without setting this and (on average) it shouldn't have an impact on rendering or performance. - -jOrGe W. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAki0FvcACgkQ72r0i/n44hOv7ACdEDJNgZ40IGoLyWm6UCNsd3nF aZsAn25lajC6ctBcnF1Ei3hDlZ0p9t1B =D36M -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mesa3d-dev mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
