Member Function Documentation

ChAABB chrono::ChCollisionModelBullet::GetBoundingBox ( ) const

overridevirtual

Returns the axis aligned bounding box (AABB) of the collision model.

Note that SyncPosition() should be invoked before calling this.

bool chrono::ChCollisionModelBullet::SetSphereRadius	(	double	coll_radius,
		double	out_envelope
	)

If the collision shape is a sphere, resize it and return true (if no sphere is found in this collision shape, return false).

It can also change the outward envelope; the inward margin is automatically the radius of the sphere.
