It may turn out to be more complicated in practice. For general-purpose antialiasing, the 3D world abandoned area-sampling for point-sampling six or seven years ago. Area-sampling turned out to be less-suitable for high performance hardware implementation, and caused problems for both multipass methods and depth buffering. The filtering issues, though real, were considered less important (as seen from the fact that multisampling hardware stuck with box filtering for several generations). As Alvy Ray Smith says, "a pixel is not a little square." Allen _______________________________________________ Render mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/render
