The Mesa 3D Graphics Library 18.3.4 / 19.0 RC6 Description:
Mesa Mesa can be used in a wide range of environments, grazing from complete hardware acceleration for modern graphics processing units to traditional software emulation, based on a plethora of device drivers. The project provides OpenGL support to Linux and UNIX platforms on top of an existing X.Org (X11 Window System) display server, and ties into other open source projects, including the Direct Rendering Infrastructure (DRI). Because of legal reasons, users shouldn’t refer to the Mesa library as MesaGL. It's just Mesa or the Mesa 3D graphics library. By default, it’s supported on Linux and FreeBSD operating systems, as well as other Unices. Mesa was initially created in August 1993 by Brian E. Paul, a computer programmer awarded with the Free Software Award by the Free Software Foundation (FSF). He’s still maintaining the project, which is now hosted by freedesktop.org.
