Eric Haines sent me the following URL for a PIII-optimized vector math library called OpenML: http://people.we.mediaone.net/seanpalmer/openlib.html Perhaps someone could use it as a guide for implementing PIII optimizations. At SIGGRAPH I picked up AMD's 3.0 SDK CD-ROM which contains docs, sample code and utilities for AMD cpu optimizations, including the new Athlon CPU. This info might also be available from AMD's web site. Anyway, maybe someone could make use of this info for Mesa optimizations. -Brian _______________________________________________ Mesa-dev maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-dev
