Mesa3D, Utilities, The Mesa 3-D Graphics Library This directory contains Mesa 3.4.1 for OpenVMS "Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL.* To the extent that Mesa utilizes the OpenGL command syntax or state machine, it is being used with authorization from Silicon Graphics, Inc(SGI). However, the author does not possess an OpenGL license from SGI, and makes no claim that Mesa is in any way a compatible replacement for OpenGL or associated with SGI. Those who want a licensed implementaion of OpenGL should contact a licensed vendor. While Mesa is not a licensed OpenGL implementation, it is currently being tested with the OpenGL conformance tests. For the current conformance status see the CONFORM file included in the Mesa distribution. Despite these technical/legal terms, you may find Mesa to be a valid alternative to OpenGL. Most applications written for OpenGL can use Mesa instead without changing the source code. Please do not refer to the library as MesaGL (for legal reasons). It's just Mesa or The Mesa 3-D graphics library. * OpenGL is a trademark of Silicon Graphics Incorporated."
