The present invention is related to rendering computer animated video and/or images generally, and to efficiently intersecting rays with an object scene while shading complex object representations. The present invention, generally, includes creating a plurality of representations for the object. After creating the plurality of representations, a plurality of primary positions are established on one of the representations. Shading positions on one or more other representations included in the plurality of representations are then established by reference to the primary positions. These shading positions correspond to the plurality of primary positions and each of these representations has a coarser resolution than the representation with the primary positions. Shading values for the shading positions are the computed and applied to the plurality of primary positions.
