Hmmm... looks like a Z-Buffering problem, if I zoom out a lot and then
rotate I can see odd effects but at the default zoom it looks fine. From
what Alessandro says about the commenting the clip set out it appears
you are setting the front/back clip ranges too far away for your cards
Z-Buffer.
su.getViewer().getView().setFrontClipPolicy(View.VIRTUAL_EYE);
su.getViewer().getView().setBackClipPolicy(View.VIRTUAL_EYE);
su.getViewer().getView().setBackClipDistance(400);
su.getViewer().getView().setFrontClipDistance(400.0/600.0);
This is what I do in my little project, the front clip should always be
within a certain ratio to the back clip,
ie
backclip = x
frontclip = x/600.0
I'm not sure where the 600 comes from but I remember it being used as a
good example (I think it's in relation to using the default 16bit Z
Buffer).
Alternatively you should be able to get better range if your card
supports a 24/32bit Z Buffer, check the driver settings.
Have fun,
Jason.
