Abstract in different language: In this paper, we present an interactive declarative modelling approach devoted to the design of urban layout. Declarative modelling palliates the weaknesses of imperative techniques. The scene model is described by means of properties without knowing explicitly its geometrical model. From a scene description a set of solutions fitting the properties is obtained. In our approach, the designer describes the urban layout with a description language in an hierarchical and incremental way. The scene description is translated in a constraint graph which is instanciated to compute one solution or a few solutions using a constraint propagation algorithm and a scene generation model. From the scene generation model providing a particular solution, a geometric model (2D map) is extracted. A 3D model of the urban environment can be generated for urban simulations or virtual reality applications.
