From f7eb54a12f65deb46a52e4d15a6e537f49f3287b Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Fri, 19 Aug 2005 00:48:25 +0000 Subject: Enable ARB_texture_compression. The code has been in place for a long time, but, for whatever reason, the extension wasn't enabled. Add some comments to i810ChooseTextureFormat. There's some strangeness with i810 texture formats. --- src/mesa/drivers/dri/i810/i810context.c | 2 ++ src/mesa/drivers/dri/i810/i810tex.c | 12 ++++++++++++ 2 files changed, 14 insertions(+) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i810/i810context.c b/src/mesa/drivers/dri/i810/i810context.c index 8389321924..47c41c5db2 100644 --- a/src/mesa/drivers/dri/i810/i810context.c +++ b/src/mesa/drivers/dri/i810/i810context.c @@ -63,6 +63,7 @@ SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. #include "utils.h" #define need_GL_ARB_multisample +#define need_GL_ARB_texture_compression #include "extension_helper.h" #ifndef I810_DEBUG @@ -122,6 +123,7 @@ const struct dri_extension card_extensions[] = { { "GL_ARB_multisample", GL_ARB_multisample_functions }, { "GL_ARB_multitexture", NULL }, + { "GL_ARB_texture_compression", GL_ARB_texture_compression_functions }, { "GL_ARB_texture_env_add", NULL }, { "GL_ARB_texture_mirrored_repeat", NULL }, { "GL_EXT_stencil_wrap", NULL }, diff --git a/src/mesa/drivers/dri/i810/i810tex.c b/src/mesa/drivers/dri/i810/i810tex.c index 34a299ae74..0aba8e8aa5 100644 --- a/src/mesa/drivers/dri/i810/i810tex.c +++ b/src/mesa/drivers/dri/i810/i810tex.c @@ -434,6 +434,14 @@ static void i810DeleteTexture( GLcontext *ctx, struct gl_texture_object *tObj ) _mesa_delete_texture_object(ctx, tObj); } +/** + * Choose a Mesa texture format to match the requested format. + * + * \todo + * Determine why \c _mesa_texformat_al88 doesn't work right for + * \c GL_LUMINANCE_ALPHA textures.
