<H1>Introduction</H1>

<p>
|

Mesa is a 3-D graphics library with an API which is very similar to
|
||||
that of <a href="http://www.opengl.org/" target="_parent">OpenGL</a>.*
|
||||
To the extent that Mesa utilizes the OpenGL command syntax or state
|
||||
machine, it is being used with authorization from <a
|
||||
href="http://www.sgi.com/" target="_parent">Silicon Graphics,
|
||||
Inc.</a>(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.
|
||||
Mesa is an open-source implementation of the
|
||||
<a href="http://www.opengl.org/" target="_parent">OpenGL</a> specification -
|
||||
a system for rendering interactive 3D graphics.

reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
|

library</em>. <br>
|
||||
A variety of device drivers allows Mesa to be used in many different
|
||||
environments ranging from software emulation to complete hardware acceleration
|
||||
for modern GPUs.

The new Shading Language compiler branch has been merged into the git

master branch. This is a step toward hardware support for the OpenGL
|

2.0 Shading Language and will be included in the next Mesa release.
