ConformanceNist.Lights.DirectionalLight.test_red_on_blue
public class test_red_on_blue extends Object

This test addresses the ability of a browser to apply a colored (red) light on an object of a different color (blue). Four simple geometries are defined in the local coordinate system and the emissive and diffuse color are both set to 0 0 1. A DirectionalLight is also defined and a red color is associated with it. This light illuminates the objects making them look black. The dot product of the light and object color produce a black appearing object.
