That one is pretty interesting in that he shows how to use vertex shaders. I also found this one which has a (OS/X only unfortunately) nice demo program: http://arek.bdmonkeys.net/bugs/invariance/TexAA.html I think he is mistaken about using this for triangles, but the ability to do round line caps and joins looks clever, and the use of a mipmap texture rather than a shader too. -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
