test_direffect_diffusecom.x3d

This test addresses the effect of the light direction on the diffuse color of a complex geometry. One ElevationGrid 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 increased as the test progresses and the diffuse color brightness of the object should also increase at those points where the light shines directly on them. The direction values used are: 1 0 0,0 0 -1,-1 0 0 0 0 1. The geometry is originally defined with a diffuseColor of 0 0 1.
