Each texture format must implement this function. The -function is totally responsible for converting the user's texture -image into the specific format. A few helper functions makes this -relatively simple. - -Overall, the code is much simpler, cleaner and easier to work with -now. Adding new texture formats is straight-forward and there's no -longer any distinction between "hardware" and "software" formats. - -Finally, the code for compressed texture images has been reorganized -as well. - -Removed files: - texutil.c - texutil.h - texutil_tmp.h - -New files: - texcompress_s3tc.c - texcompress_fxt1.c - - - -Driver / context changes ------------------------- - -The _mesa_create_context() and _mesa_initialize_context() function -parameters have changed. They now take a pointer to a struct -dd_function_table. Drivers can initialize this table by calling -_mesa_init_driver_functions(). Drivers should then plug in the special -functions they implement. In particular, the ctx->Driver.NewTextureObject -pointer _must_ be set so that the default texture objects created in -_mesa_create/initialize_context() are correctly built. - -The _mesa_init_driver_functions() function allows a lot of redundant code -to be removed from the device drivers (such as initializing -ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to -the dd_function_table can be done with less hassle since the pointer can -be initialized in _mesa_init_driver_functions() rather than in _all_ the -drivers. - - -Device Drivers --------------- - -Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5 -depending on the device driver's capabilities. For example, if the -driver enables all the ARB extensions which are part of OpenGL 1.5 -then glGetString(GL_VERSION) will return "1.5". Otherwise, it'll -return "1.4" or the next lower version that implements all required -functionality. - -A number of Mesa's software drivers haven't been actively maintained for -some time. We rely on volunteers to maintain many of the drivers. -Here's the current status of all included drivers: - -Driver Status ----------------------- --------------------- -XMesa (Xlib) implements OpenGL 1.5 -OSMesa (off-screen) implements OpenGL 1.5 -Glide (3dfx Voodoo1/2) implements OpenGL 1.3 -SVGA implements OpenGL 1.3 -Wind River UGL implements OpenGL 1.3 -Windows/Win32 implements OpenGL 1.5 -DJGPP implements OpenGL 1.5 -GGI implements OpenGL 1.3 -BeOS implements OpenGL 1.5 -Allegro needs updating -D3D needs updating - - - -Other Changes -------------- - -See the VERSIONS file for more details about bug fixes, etc. in Mesa 6.1. - - ----------------------------------------------------------------------- -$Id: RELNOTES-6.1,v 1.1.1.4 2004/08/28 04:27:00 kem Exp $ |
