|
|
|
|
<p>
|
|
This is a brief summary of Mesa's directory tree and what's contained in
|
|
each directory.
|
|
</p>

<ul>
|
|
<li><b>docs</b> - Documentation
|

<li><b>docs</b> - EGL documentation
|
|
<li><b>drivers</b> - EGL drivers
|
|
<li><b>main</b> - main EGL library implementation. This is where all

the EGL API functions are implemented, like eglCreateContext().

</ul>
|
|
<li><b>glsl</b> - the GLSL compiler
|
|
<li><b>mapi</b> - Mesa APIs
|
|
<li><b>glapi</b> - OpenGL API dispatch layer. This is where all the
|
|
GL entrypoints like glClear, glBegin, etc. are generated, as well as

|
|
directory may be moved to src/mesa/drivers/gallium at some point.
|
|

|
|
lines, triangles, bitmaps, images, etc. in software.

|
<li><b>vbo</b> - Vertex Buffer Object code. All drawing with
|
|
glBegin/glEnd, glDrawArrays, display lists, etc. goes through this
|
|
module. The results is a well-defined set of vertex arrays which
|
|
are passed to the device driver (or tnl module) for rendering.
|

Intended for use by drivers for hardware that does not have
|
|
vertex shaders.
|
