Generation of textures and geometric pseudo-urban models with the aid of IFS

Résumé

This paper explains our attempt to capture inner coherence of urban shapes and morphologies, by fractal analysis of 2D_ textures (top view + height) of real and synthetic city maps. The basic ideas lean on autosimilarity detection, fractal coding of regions, and processing with Iterated Function Systems (IFS). We introduce a genetic-like approach, allowing interpolation, alteration and fusion of different urban models, and leading to global or local synthesis of new shapes. Finally, a 3D reconstruction tool has been developed for converting textures to volumes in VRML, simplified enough for real time wanderings, and enhanced by some automatically generated garbage dump and decorated elements. Programs and graphic interface are developed with C++ and QT libraries
