I don't know enough of your app to understand what "looks wrong" to you.. In
the second screenshot there are empty bands in the middle of the box.. is
that what you are referring to? If that happened during a rotation I would
suspect the normals were wrong.

It could be I am not sure, I was just wondering about clipping how it
could create such an effect, like in the attached screenshot. Why can I
see the above box and some boxes underneath but sometimes not the boxes in
beetween?
I think I am not resetting the clipping planes, when I am rotating, can
this cause the problem?
The values of the clipping plane in the screenshot are:
front 0.026723915100097657 back 66.80978775024414 ratio 2500.0
