Hi, I have read about the issue of implementing the S3TC Extension in Mesa: http://dri.freedesktop.org/wiki/S3TC/
As I understood, the problem is, that encoding and decoding S3TC in software is covered by patents, while passing S3TC compressed data to the GPU is still ok. AS NOW: If "force_s3tc_enable" is enabled in Mesa3D, uploading a S3TC encoded texture works if format==internalFormat is true. If format!=internalFormat is true, it would fail (as i know). SO MY PROPOSAL: If 'format' is one of the S3TC types, and format!=internalFormat is true, then set internalFormat:=format. Else, if 'internalFormat' is one of the S3TC types, but the 'format' isn't, set internalFormat:=format (or any other format, Mesa3D can encode). _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
