- Mesa 4.0 release notes
-
- October 18, 2001
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 3.3) designate new developmental releases.
-Even numbered versions (such as 3.4) designate stable releases.
-
-Mesa version 4.0 signifies two things:
-
- 1. 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
