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
|
|
|
|

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:

The XFree86/DRI drivers have not yet been updated to use Mesa 4.0 as of
|
|
|
|
|
September 2001, but that should happen eventually.
