use:
BoundingSphere bs = new BoundingSphere(Node.getBounds()) ;
but maybe it's more efficient to use:
Bounds b = Node.getBounds() ;
BoundingSphere bs ;
if(b instanceof BoundingSphere)
bs = (BoundingSphere)b ;
else
bs = new BoundingSphere(b) ;
The average should be better because if the bounds you get are already a
sphere you avoid memory allocation.
