Our work aims at defining a complete system for defining efficient representations dedicated to architectural environments. We are interested in modeling, rendering and lighting simulations. Therefore, we propose a topological model including semantics, geometry, photometry and radiometry descriptions. We have defined a hierarchical approach for modeling with multi-partitions. Our lighting simulation system handles very large building, either with radiosity or photon shooting, on a single processor or with a parallel system.
