<p>
<a class="link" href="GritsOpenGL.html" title="GritsOpenGL"><span class="type">GritsOpenGL</span></a> is the core rendering engine used by grits. Theoretically other
renderers could be writte, but they have not been. GritsOpenGL uses the ROAM
algorithm for updating surface mesh the planet. The only thing GritsOpenGL
can actually render on it's own is a wireframe of a sphere.
</p>
<p>
GritsOpenGL requires (at least) OpenGL 2.0.
