Open GL Interview Question:

What is Silicon Graphics policy on "free"
implementations of APIs which resemble the OpenGL API?

Submitted by: Administrator

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.
