Silicon Graphics, as licensor of the OpenGL(R) trademark, does not

permit non-licensed use of the OpenGL trademark, nor does it permit

non-licensed use of the OpenGL conformance tests. Silicon Graphics

provides a source code sample implementation of OpenGL, but only to

companies and organizations which agree to the terms and conditions of

an OpenGL license.

Silicon Graphics does give permission to others to create and distribute

their own implementations of the OpenGL API, provided they do not

state nor imply they have the right to use the OpenGL(R) trademark to

name their product, nor make claims to conformance based upon the ARB

controlled OpenGL conformance tests. Silicon Graphics agrees to allow

others to copy the OpenGL header files, as much as is necessary, for

the creation of other implementations.

Silicon Graphics is in no way associated nor endorsing these

other graphics libraries. Silicon Graphics does not make any

claims or guarantees as to the quality, performance, nor

completeness of an unlicensed library.
