Re: papervision camera formula (was: screen space to 3D space...)

We've got:

Camera3D : default camera with a target
FreeCamera3D : default camera with no target
=> those two use 'focus' and 'zoom'.
These two values are somewhat arbitrary : you need to find out
yourself whicg settings suits best.

Then we got:

FrustumCamera3D : a camera which us created using a FOV and a viewport.
FOV is as in any 3D camera: so a FOV of 60 _is_ 60, NOT 30.

Agree that documentation could be better :-)
