Hi,

does anybody would be willing to share a piece of code that has been used
successfully to set the viewing frustum in a CAVE-like system from an
head-tracker.
As a verification, we displayed a model of the cave (a cube done with 12
cylinders)
in the cave itself and we move the tracker around. As the tracker moves, the
projection
of the cave on the walls should stay the same since the projection of the
walls of the
cave on themselves are the walls themselves. However, the cylinder
representing the
cave are moving all around the place, in a way that suggest that the frustum
is not
changed but still have the same field of view.

Any body could give some insight on this problem?

thanks

Yohan
