Hi,
Yes, the computeHomePosition calculates a position and set's it. In my case i'm
not able to change the camera positon at all because it is fixed.
I'm able to change the orientation and the fov (by the frustum).
bs = bounding sphere
You have the range (cam pos - bs center) and the bs radius, so atan
would give half the fov needed to fit the bs. You'll have to adjust
horiz/vert fov depending on your window aspect.

Perhaps the osgShadow::MinimalShadowMap class does this kind of frustum calculation to minimize the fov of the camera that collects the shadowmap?
Thank you!
Cheers,
Johannes
