Hello! I have a problem with distortion my gluSphere during an animation. I don't now how to precisely describe this, so I uploaded short video: click. When I turn a lighting off there is no more distortion when a ball comes within lines.
A lighting is based on one positional light with constant attenuation and the light model ambient. The program is created in Java (jogl 1.1.1.a).
What's the problem ?
