Detailed Description

The gmGraphics module provides nodes primarily for graphics rendering pipeline definition and handling.

A Window creates a graphics context and makes it current before any subsequent calls. The Window calls a View to produce graphics. A View may call other views recursively, or make one or more calls to one or more renderers to produce this graphics. It is the renderer that actually renders the scene, while the view determines frame buffers and frustum settings to use, based on the current Viewpoint.
