Portals and Mirrors: Simple, Fast Evaluation of Potentially Visible Sets

We describe an approach for determining potentially visible sets in dynamic architectural models. Our scheme divides the models into cells and portals, computing a conservative estimate of which cells are visible at render time. The technique is simple to implement and can be easily integrated into existing systems, providing increased interactive performance on large architectural models.
