Short name for C for Graphics.

Cg is a high-level shading language created by NVIDIA for programming vertex and fragment shaders.

See [1] or [2] for more information.

Note: The Cg Toolkit is no longer under active development or support.

Tcl3D provides a wrapper of the Cg library (Version 2.2.006). It also has some demonstration programs [3] using Cg.
