Michael,
I could not find anything in the new features that might explain what I am
seeing?
The nearest that I could find is at:
http://developer.java.sun.com/developer/earlyAccess/java3D/java3d-bugs.html
Under Core Bugs (j3d and vecmath) it lists the following 2 known bugs:
bounds used in getInfluencing{lights, fog, alternateappearance} is incorrect
Collision does implicit conversions of bounds types
I dont know what these mean? but what I am seeing seems wider than these
imply?
Martin
