Hi Ahmed, The OSG does not have a inbuilt collision detection system.
There is support for doing intersection using the osgUtil::IntersectionVisitor coupled with osgUtil::*Intersector implementation. The PolytopeIntersection is probably the closest to what you require. You'd need to create a polytope around your first object and then visit the scene graph using the IntersectionVisitor to find all the intersections. Robert.
