[Dri-devel] Who is working on Texture Compression (other than me?)

[Bill W. <bil...@gr...>]

Who is working on texture compression in Mesa?  I have an implementation
of the ARB extension (mostly done by Brian Paul) and an implementation of
the GL_3DFX_texture_compression_FXT1 extension.  These are in the 
tdfx-2-1-branch
branch of the DRI tree.

If someone else is working on this, and depends on the implementation, please
let me know.  For something I am working on, the driver interface needs to
change.  In particular, there is a routine which calculates the specific
texture compression format given a generic one.  For example, given
GL_COMPRESSED_RGB_ARB, the routine might return GL_COMPRESSED_RGB_FXT1_3DFX.
This routine needs to have more parameters to support some more compressed
texture formats.

Please let me know if you are working in this area, and I can give you
more details.  They are generally pretty harmless, and I think they are
backward compatible, though I have not tested for this.
