I was wondering if I might have a few signposts here; what methods
in the extension of MouseBehavior3D would need to be implemented? Or
would I need to create a new version of MouseHelper?

On a different note, is it possible to have "pick-like" things happen on
a hover, rather than on a "click"? (Such as popping up information on the
point you are over)

Thanks, Donna
