- Mesa 3.1 release notes
-
- PLEASE READ!!!!
-
-
-New copyright
--------------
-
-Mesa 3.1 will be distributed under an XFree86-style copyright instead
-of the GNU LGPL.
-
-
-New directories
----------------
-
-All documentation files are now in the docs/ directory.
-All shell scripts are now in the bin/ directory.
-
-
-New library names
------------------
-
-Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
-and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
-
-Now, the main library is named libGL.so (or libGL.a) and the GLU library
-is named libGLU.so (or libGLU.a).
-
-The change allows Mesa to be more easily substituted for OpenGL.
-Specifically, the linker/loader on some Unix-like systems won't
-allow libMesaGL.so to be used instead of libGL.so if the application
-was linked with the former.
-
-Warning: if you have another OpenGL implementation installed on your
-system (i.e. you have another OpenGL libGL.so) you'll have to be
-carefull about which library (OpenGL or Mesa) you link against. Be
-aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
-variable.
-
-
-New library versioning
-----------------------
-
-Previously, the Mesa GL library was named libMesaGL.so.3.0
-To better support Linux/OpenGL standards, the Mesa GL library is now
-named libGL.so.1.2.030100 This indicates version 1.2 of the OpenGL spec
-and Mesa implementation 3.1.0
-
-In the long term this will allow better interoperability with other
-OpenGL implementations, especially on Linux. In the short term,
-OpenGL apps may have to be relinked to use the new library naming.
-
-
-
-New makefiles
--------------
-
-The old Makefiles found in the various directories have been renamed
-to Makefile.X11 in order to prevent filename collisions with autoconfig-
-generated Makefiles.
-
-The top-level Makefile simply includes Makefile.X11
-If your top-level Makefile get's overwritten/destroyed you can restore
-it by copying Makefile.X11 to Makefile
-
-
-New extensions
---------------
-
-GL_EXT_stencil_wrap
- Implements two new stencil operations: GL_INCR_WRAP_EXT and
- GL_DECR_WRAP_EXT which allow stencil increment and decrement
- without clamping.
-
-GL_INGR_blend_func_separate
- Allows specification of blend factors for RGB and Alpha independently.
- (INGR = Intergraph)
-
-GL_ARB_multitexture
- Multiple simultaneous textures. (ARB = Architecture Review Board)
-
-GL_NV_texgen_reflection
- nVidia texgen extension for better reflection mapping.
-
-GL_PGI_misc_hints
- Assorted transformation hints.
-
-GL_EXT_compiled_vertex_array
- Compiled vertex arrays.
-
-GL_EXT_clip_volume_hint
- Allows one to disable clip volume (frustum) testing.
-
-
-
-Extensions removed
-------------------
-
-GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
-
-
-
-Config file
------------
-
-By default, /etc/mesa.conf will be read when Mesa starts. This
-file controls default hints, enable/disable of extensions, and
-more. See the CONFIG file for documentation.
-
-
-
-Optimizations
--------------
-
-Keith Whitwell has contributed significant optimizations to Mesa's
-vertex transformation code. Basically, the whole transformation
-stage of Mesa has been rewritten.
-
-It's impossible to give a speedup factor. You'll just have to
-try your app and see how it performs.
-
-
-
-Device Driver changes
----------------------
-
-A bunch of new device driver functions have been added. See src/dd.h
-Keith Harrison contributed many of them. I've been planning on adding
-a bunch of functions like these to make writing hardware drivers easier.
-More such function will probably be added in the near future.
-
-
-
-Miscellaneous
--------------
-
-util/glstate.c has some handy functions for debugging. Basically, it
-offers a simple function for printing GL state variables. It's not
-finished yet. There's a LOT more GLenum records to be added (see the
-code). Anyone want to help?
