12 Mesa is an open-source implementation of the OpenGL specification.
13 OpenGL is a programming library for writing interactive 3D applications.

17 Mesa 9.x supports the OpenGL 3.1 specification.
22 Yes. Specifically, Mesa serves as the OpenGL core for the open-source
38 Hardware-accelerated OpenGL implementations are available for most
44 -  Mesa is quite portable and allows OpenGL to be used on systems that
45    have no other OpenGL solution.
48 -  A software implementation of OpenGL is useful for experimentation,
66 -  The GLX wire protocol is not supported and there's no OpenGL
69 -  The OpenGL library, ``libGL.so``, contains everything (the
72 Alternately, Mesa acts as the core for a number of OpenGL hardware
90 1.6 Are there other open-source implementations of OpenGL?
93 Yes, SGI's `OpenGL Sample Implementation
95 is available. The SI was written during the time that OpenGL was
100 implementation of OpenGL ES for mobile devices.
103 is a subset of OpenGL for PalmOS devices. The website is gone, but the
107 `TinyGL <http://bellard.org/TinyGL/>`__ is a subset of OpenGL.
109 `SoftGL <https://sourceforge.net/projects/softgl/>`__ is an OpenGL
113 OpenGL implementation (it's layered upon OpenGL), but it does export the
114 OpenGL API. It allows tiled rendering, sort-last rendering, etc.
117 is an OpenGL subset library for TI graphing calculators.
119 There may be other open OpenGL implementations, but Mesa is the most
134 You're application is written in IRIS GL, not OpenGL. IRIS GL was the
135 predecessor to OpenGL and is a different thing (almost) entirely. Mesa's
