This paper presents a topology-based representation dedicated to complex indoor scenes. It accounts for memory management and performances during modeling, visualization and lighting simulation. We propose to enlarge a topological model (called generalized maps) with multi-partition and hierarchy. Multi-partition allows the user to group objects together according to semantics. Hierarchy provides a coarse-to-fine description of the environment. The topological model we propose has been used for devising a modeler prototype and generating efficient data structure in the context of visualization, global illumination and 1GHz wave propagation simulation. We presently handle buildings composed of up to one billion triangles.
