savage texture compression - good news

[Mark Cass]

guys,   finally have some good news. uploading DXT1, DXT3, and DXT5 compressed textures is working. i still need to implement compressed sub textures and test very small textures.   the issue was the tile size. i wrote an iterator into the driver to test all possible tile sizes and found the one that worked. well, actually two that worked. DXT1 has a different tile format than DXT3 and DXT5 which share the same format.   my next question involves extensions. should the GL_ARB_texture_compression and GL_EXT_texture_compression_s3tc extensions be enabled? the only reason i ask is that i think the complete description of the extension includes the ability for the driver to compress the textures. as was mentioned previously, adding this ability to the driver could result in legal problems as s3tc is intellectual property of S3/VIA inc.   mark
