Hi Luc,
I think the appropriate way to do this would be to extend the
CenterMode enum to something like:
enum CenterMode
{
USE_BOUNDING_SPHERE_CENTER,
USER_DEFINED_CENTER,
UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED
};
The actual enum name is a bit of awkward here as it really should be
BoundingVolumeMode or something similar as it's not just the center
that is being updated.
Thoughts?
Robert.
