I have a problem with pointsprite and Collision detection.
I'm building a pointSprite in the same way as in sample osgpointsprite (
osg::Geode with a Pointsprites stateset).
I'd like to pick my object with an associated pointsprite stateset like
in the osg-Picking example. I can not pick it !
Pointsprites are just points to the intersection algorithm and so suffer
the same problem as picking lines i.e. they have no size. You have to
use a swept sphere or something like it to pick a volume instead of a
infinitely thin line.
There was a thread on the mailing list a while ago that might help you
along.
