-Mesa is an open-source implementation of the -OpenGL specification - +The Mesa project began as an open-source implementation of the +OpenGL specification - a system for rendering interactive 3D graphics.
-A variety of device drivers allows Mesa to be used in many different -environments ranging from software emulation to complete hardware acceleration -for modern GPUs. +Over the years the project has grown to implement more graphics APIs, +including +OpenGL ES (versions 1, 2, 3), +OpenCL, +OpenMAX, +VDPAU, +VA API, +XvMC and +Vulkan. +

+Version 9.x features
++Version 9.x of Mesa implements the OpenGL 3.1 API. +While the driver for Intel Sandy Bridge and Ivy Bridge is the only +driver to support OpenGL 3.1, many developers across the open-source +community contributed features required for OpenGL 3.1. The primary +features added since the Mesa 8.0 release are +GL_ARB_texture_buffer_object and GL_ARB_uniform_buffer_object. +
++Version 9.0 of Mesa also included the first release of the Clover state +tracker for OpenCL. +
+ + +Version 8.x features
++Version 8.x of Mesa implements the OpenGL 3.0 API. +The developers at Intel deserve a lot of credit for implementing most +of the OpenGL 3.0 features in core Mesa, the GLSL compiler as well as +the i965 driver. +
