Mesa is a 3-D graphics library with an API which is very similar to that
|
|
of `OpenGL <https://www.opengl.org/>`_ [1]_.
|
|
To the extent that Mesa utilizes the OpenGL command syntax or state
|
|
machine, it is being used with authorization from `Silicon Graphics,
|
|
Inc. <https://www.sgi.com/>`__\ (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 implementation of OpenGL should contact a
|
|
licensed vendor.
|
|
|
|
Please do not refer to the library as *MesaGL* (for legal reasons). It's
|
|
just *Mesa* or *The Mesa 3-D graphics library*.
