test_direffect_diffusesim.x3d

(.x3d scene, pretty-print source, statistics, info & logs, X3DOM Player)

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