| 7 | Mesa is a 3-D graphics library with an API which is very similar to that
|
|---|
| 8 | of `OpenGL <https://www.opengl.org/>`_ [1]_.
|
|---|
| 9 | To the extent that Mesa utilizes the OpenGL command syntax or state
|
|---|
| 10 | machine, it is being used with authorization from `Silicon Graphics,
|
|---|
| 11 | Inc. <https://www.sgi.com/>`__\ (SGI). However, the author does not
|
|---|
| 12 | possess an OpenGL license from SGI, and makes no claim that Mesa is in
|
|---|
| 13 | any way a compatible replacement for OpenGL or associated with SGI.
|
|---|
| 14 | Those who want a licensed implementation of OpenGL should contact a
|
|---|
| 15 | licensed vendor.
|
|---|
| 16 |
|
|---|
| 17 | Please do not refer to the library as *MesaGL* (for legal reasons). It's
|
|---|
| 18 | just *Mesa* or *The Mesa 3-D graphics library*.

| 27 | copyrights and licenses apply to different components. For example, the
|

| 28 | GLX client code uses the SGI Free Software License B, and some of the
|

| 29 | Mesa device drivers are copyrighted by their authors. See below for a
