This program tests the basic lighting channel controls using one light positioned at the viewpoint and directed down the Z-axis. Three identical models are rendered, each rotating about a different axis. You can select any of the GXDraw* procedural models, change ambient and material register colors, and turn smooth shading on and off.
This test uses only the GX_COLOR0 channel.
