Rendering in this case does nothing more than searching for intersection
in a certain raster like the method i suggested. The problems are the
same, if the intersection is too small in relation to the render
resolution or the object is not visible in the render camera, the result
will be wrong.  Furthermore scanning the whole camera angle is much less
efficient than scanning only the intersection of the bounding boxes.
