In looking at the docs, I realized that the mach64 seems not to support mipmapping on the secondary texture, as there is only one register for a secondary texture offset, as opposed to the 11 for the primary texture. It seems as the though the second "texture unit" isn't really a fully fledged texture pipeline as it is in other cards (Rage 128 has 2 separate tex_cntl regs and a full set of offsets for the second texture unit).
And lending credence to the assertion that mipmapping is broken in hardware on mach64, I compiled the mipmap Mesa demo in Windows and the ATI driver doesn't support mipmapping either, you just get a yellow triangle. -- Leif Delgass http://www.retinalburn.net _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
