A stabilization of the 3.5 development release - 2. Implementation of the OpenGL 1.3 specification - - -Note that the Mesa major version number is incremented with the OpenGL -minor version number: - - Mesa 1.x == OpenGL 1.0 - Mesa 2.x == OpenGL 1.1 - Mesa 3.x == OpenGL 1.2 - Mesa 4.x == OpenGL 1.3 - - - -New Features ------------- - -Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as -extensions. These extensions were simply promoted to standard features: - - GL_ARB_multisample - GL_ARB_multitexture - GL_ARB_texture_border_clamp - GL_ARB_texture_compression - GL_ARB_texture_cube_map - GL_ARB_texture_env_add - GL_ARB_texture_env_combine - GL_ARB_texture_env_dot3 - GL_ARB_transpose_matrix - -In Mesa 4.0 the functions defined by these extensions are now available -without the "ARB" suffix. For example, glLoadTransposeMatrixf() is now -a standard API function. The new functions in OpenGL 1.3 and Mesa 4.0 are: - - glActiveTexture - glClientActiveTexture - glCompressedTexImage1D - glCompressedTexImage2D - glCompressedTexImage3D - glCompressedTexSubImage1D - glCompressedTexSubImage2D - glCompressedTexSubImage3D - glGetCompressedTexImage - glLoadTransposeMatrixd - glLoadTransposeMatrixf - glMultiTexCoord1d - glMultiTexCoord1dv - glMultiTexCoord1f - glMultiTexCoord1fv - glMultiTexCoord1i - glMultiTexCoord1iv - glMultiTexCoord1s - glMultiTexCoord1sv - glMultiTexCoord2d - glMultiTexCoord2dv - glMultiTexCoord2f - glMultiTexCoord2fv - glMultiTexCoord2i - glMultiTexCoord2iv - glMultiTexCoord2s - glMultiTexCoord2sv - glMultiTexCoord3d - glMultiTexCoord3dv - glMultiTexCoord3f - glMultiTexCoord3fv - glMultiTexCoord3i - glMultiTexCoord3iv - glMultiTexCoord3s - glMultiTexCoord3sv - glMultiTexCoord4d - glMultiTexCoord4dv - glMultiTexCoord4f - glMultiTexCoord4fv - glMultiTexCoord4i - glMultiTexCoord4iv - glMultiTexCoord4s - glMultiTexCoord4sv - glMultTransposeMatrixd - glMultTransposeMatrixf - glSampleCoverage - glSamplePass - - -GLX 1.4 is the companion to OpenGL 1.3. The only new features in GLX 1.4 -are support for multisampling and the GLX_ARB_get_proc_address extension. -glXGetProcAddress() is the only new function in GLX 1.4. - - - -Multisample and Texture Compression ------------------------------------ - -The OpenGL 1.3 specification allows the multisample and texture compression -features to essentially be no-ops. For example, if you query for multisample -support you'll find none, but the API functions work. - -Similarly, texture compression is not implemented by any of the software -drivers but you can specify a generic compressed texture format (like -GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted. - - - -Device Drivers --------------- - -Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the -device driver. If the driver enables all the ARB extensions which are part -of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise, -it'll return "1.2". - -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 1.3 -OSMesa (off-screen) implements OpenGL 1.3 -FX (3dfx Voodoo1/2) implements OpenGL 1.3 -SVGA implements OpenGL 1.3 -Wind River UGL implements OpenGL 1.3 -Windows/Win32 implements OpenGL 1.3 -GGI needs updating -DOS/DJGPP needs updating -BeOS needs updating -Allegro needs updating -D3D needs updating -DOS needs updating - -Special thanks go to Karl Schultz for updating the Windows driver. - -The XFree86/DRI drivers have not yet been updated to use Mesa 4.0 as of -September 2001, but that should happen eventually. - - - -Other Changes -------------- - -See the VERSIONS file for more details about bug fixes, etc. in Mesa 4.0. - - ----------------------------------------------------------------------- -$Id: RELNOTES-4.0,v 1.1.1.4 2004/08/12 23:43:27 anholt Exp $ |
