[JAVA3D] Strange waves in my cubes

[Patrick van Bergen]

Hai there,

I am building an application that contains a number of rounded cubes. When
these cubes overlap eachother I get these strange 'waving' effects, that can
best be explained by looking at the attached picture. I say waving because
triangular waves go through the sides of the cube when I zoom in and out of
the objects.

I tried changing some of the renderingattributes of the appearance without
much effect.

Has anyone seen such an effect before? I am not doing anything special here.
