Class test_direffect_specularsim

java.lang.Object
ConformanceNist.Lights.DirectionalLight.test_direffect_specularsim
public class test_direffect_specularsim extends Object

This test addresses the effect of the light direction on the specular color of a simple geometry. One simple geometry (Sphere) is drawn in the local coordinate system and a DirectionalLight is also defined with intensity 1 and color white. The test starts by clicking on the text above the geometry. The direction of the light is changed as the test progresses and the specular color of the objects should be brighter at those areas where the light shines directly over the object. The geometry is originally defined with a diffuseColor of 1 0 0 and a specularColor of 0 1 0. The direction values used are 0 0 1,1 0 0, 0 0 -1,-1 0 0.
