Chris,
The precision of the Z-buffer is dependent upon the graphics card /
driver not Java 3D. For a typical video card we assume 16 bits of
Z-Buffer and the recommendation of Sun for a 3000 ratio.
Note: the values that you set for front and back clip are NOT the actual
positions where the clipping will occur. These values are scaled based
on other factors of your view platform.
