I believe my problem is that I move the "camera" by changing the
ViewPlatform's transformation matrix. The camera can be moved that way,
but the ViewPlatform may not know that the transformation matrix is being
modified and so whatever bounding volume it uses to cull out geometry is
still in it's original position at (0,0, ...). This is all just guessing
here, at the risk of sounding ignorant. The way I obtain the matrix is
simpleU.getViewingPlatform().getViewPlatformTransform().
Is there a better way to move the camera around so that it follows a ship
(i.e. a TriangleArray stuck in a Shape3D stuck in a BranchGroup)?
