The ray intersection kernel handles only spheres, both as bounding
volume and as leaf intersection primitive.
You could add a second kernel to handle bounding boxes as bounding
volume and as leafs. You could include a transformation matrix in each
node in order to relax the constrain of having the axis aligned boxes.
