What support for OpenGL does {Open,Net,Free}BSD or Linux provide?
The X Windows implementation, XFree86 4.0, includes support for OpenGL using Mesa or the OpenGL Sample Implementation. XFree86 is released under the XFree86 license. http://www.xfree86.org/ SGI has released the OpenGL Sample Implementation as open source. It can be built as an X server GLX implementation. It has been released under SGI Free Software License B. http://oss.sgi.com/projects/ogl-sample/ The Mesa 3D Graphics Library is an OpenGL clone that runs on many platforms, including MS-DOS, Win32, *BSD and Linux. On PC UNIX platforms Mesa can be built to use GGI, X Windows, and as an X server GLX implementation. Mesa is hardware accelerated for a number of 3D graphics accelerators. Mesa 3.1 and later was released under an XFree86-style license. Versions prior to 3.1 were released under GPL. http://mesa3d.sourceforge.net/ Utah-GLX is a hardware accelerated GLX implementation for the Matrox MGA-G200 and G-400, ATI 3D RAGE PRO, Intel i810, NVIDIA RIVA, and S3 ViRGE.
