'''OpenGL extension EXT.texture3D
Overview (from the spec)
This extension defines 3-dimensional texture mapping. In order to
define a 3D texture image conveniently, this extension also defines the
in-memory formats for 3D images, and adds pixel storage modes to support
them.
One important application of 3D textures is rendering volumes of image
data.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/EXT/texture3D.txt
