Hi Kelvin,
Here is the test case for the Specular Color bug. Just move around the boxes to highlight the lateral aligned faces, and you will see the lighting difference.
OS: Win2k
Graphic card: nVidia GeForce2 MX
Java: java version "1.4.1_02" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06) Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
J3D properties: {j3d.specification.vendor=Sun Microsystems, Inc., j3d.specification.version=1.3, j3d.version=1.3.1-beta1, j3d.vendor=Sun Microsystems, Inc., j3d.renderer=OpenGL}
Cheers,
This is a bug in J3D, there is still cases it fail to detect non-uniform scale and force OGL to do a normalized. This only happen if OpenGL support rescale normal extensions.
Bug 4839757 is submitted for this.
Thanks for your test program.
