3D designers and architects often face the problem to create virtual environments with a large number of individual buildings and other objects. We have developed different techniques to facilitate this task, by allowing the designer to specify abstract descriptions of the desired geometry, such as shape grammars or graph-based descriptions. These can then be employed to interactively create a large variety of buildings and objects that conform to the description, but still display individual features. We actively research methods to facilitate the design process using visual interaction metaphors and more intuitive modeling paradigms, e.g., layer-based design of facades, or interactive floorplan design.
