Hi Boris,
my point is that I don't want to translate the object to the origine because my
objects kann have 500.000 triangles or more( and that will cost me too much
time). Until now I have translated my objects to the origine and it works fine(
and that is done with the A Matrix you suggest I should use). What I was
thinking about is(I don't know if this is possible) to translate the coordinate
origin to the center of the boundingbox und rotate my objects(using the
MouseRoate behavior).
