This paper describes the application of procedural modeling methods to automatically derive 3D models of high visual quality for a highly detailed and quick visualization of complex
city models. We discuss the applicability of a procedural modeling pipeline of shape grammars in urban planning to derive meaningful 3D city models. Therefore we analyze CGA shape, a novel
shape grammar for the procedural modeling of CG architecture, for its usage in architectural planning processes. Our system gives rise to three exciting applications in the field of city
modeling and city visualization enabling a quick decision making and iterative design workflow: modeling of master plans, evaluation of built environments and planning of urban open spaces.
It is capable to produce building shells with high visual quality and geometric detail. Context sensitive shape rules allow the user to specify interactions between the entities of the
hierarchical shape descriptions. Selected examples demonstrate solutions to previously noted challenges.
