After having read your answer i tried to move the camera away from the
objects, and I think that it was too close of the objects, because now
every object is drawned. Thanks Slime.

In fact I have an other problem, I can't get the up and right vector at a
good size, so that the view is the same as my opengl application. Does
someone would have an hint to solve that problem ?

Thanks
Bye
