* mesa: Make _mesa_get_compressed_formats match the texture compression specsIan Romanick2011-07-251-27/+90
| | | | | | | | | | | The implementation deviated slightly from the GL_EXT_texture_sRGB spec and from other implementations. A giant comment block was added to justify the somewhat odd behavior of this function. In addition, the interface had unnecessary cruft. The 'all' parameter was false at all callers, so it has been removed. Reviewed-by: Brian Paul <[email protected]>
* mesa: Add utility function to get base format from a GL compressed formatIan Romanick2011-07-251-0/+88

* mesa: add ATI_texture_compression_3dcMarek Olšák2011-03-081-0/+1
| | | | | | | LUMINANCE_ALPHA_LATC2 = LUMINANCE_ALPHA_3DC, so this is easy. Note that there is no specification for 3DC, just a few white papers from ATI.
* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-0/+18
| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.
* mesa: Add RGTC texture store/fetch support.Dave Airlie2011-02-281-0/+20
| | | | | | | | | This adds support for the RGTC unsigned and signed texture storage and fetch methods. the code is a port of the DXT5 alpha compression code. Signed-off-by: Dave Airlie <[email protected]>

* mesa: Include mtypes.h in files that use gl_context struct.Vinson Lee2011-01-051-0/+1
| | | | | | Directly include mtypes.h if a file uses a gl_context struct. This allows future removal of headers that are not strictly necessary but indirectly include mtypes.h for a file.

| | | | | | | | | | _mesa_compressed_row_stride() can go away soon. _mesa_compressed_image_address() can be generalized and moved to formats.c

| | | | | | | | | | | | | | | | | | | | | | add some more srgb texture formats, including compressed ones various fixes relating to srgb formats issues: _mesa_get_teximage is completely broken for srgb textures, both for non-compressed ones (swizzling) and compressed ones (shouldn't do standard-to-linear conversion) texelFetch function may be broken for little or big endian (or both...)

| | | | | | | all formats or just those without restrictions/limitations should be returned. We want all when validating the internalFormat parameter to glCompressedTexImage2D but only want unrestricted formats when handling the GL_COMPRESSED_TEXTURE_FORMATS query.
* More updates for texture compression.Brian Paul2006-05-081-0/+47
| | | | | | Added _mesa_compressed_texture_size_glenum() for validating the imageSize parameter to glCompressedTex[Sub]Image1/2/3() which does _not_ call ctx->Driver.CompressedTextureSize() - since that could return a padded size.
* Fix a number of texture compression issues.Brian Paul2006-05-081-40/+30
| | | | | | | | Pass the MESA_FORMAT_* token to the _mesa_compressed_row_stride(), _mesa_compressed_texture_size() and _mesa_compressed_image_address() functions since we want to use the driver-chosen format, not the user's internalFormat hint. Consolidate code related to choosing the texture format in texstoree.c
