Description
-----------

This program generates some geometry and a rocky looking texture. The geometry
distance field is generated with OpenCL and then is turned into a mesh using
the marching tetrahedrons algorithm on the CPU. The texture is generated with
OpenCL as well. The source is written in a subset of C++11 (gcc 4.6.1).

This was really just an excuse to do something with OpenCL.

I used most of the classic noise function in shaders/noise.glsl. See

Vera.ttf is included in the source. See LICENSE-vera.txt.

Sean Barrett made this public domain, and it's really handy. It's used
here mostly as-is with some minor edits to get rid of warnings.
