Thanks for your reply, Sergey. I will try it.
BTW, sometimes, I want to detect the intersection between the camera frustum
and the terrain. So,is there any way to detect the intersection between a
bounding sphere(or box) and the terrain in OSG?
Cheers

Hi
there is no collision detection in osg. You can use intersectors in osgUtil and
trace rays from camera downwards to check distance from ground, or use some
physics engine to get proper collision detection.
Cheers.
