Procedural Modeling Technology in Urban Design

Procedural modeling is one of the widespread uses in the field of computer graphics technology, even in urban design. According to the object of urban design, procedural modeling technology can be summarized in several methods: procedural modeling of cities, interactive procedural street modeling, automatically generating large urban environments based on the footprint data of buildings, cellular automata and software agents, shape grammars. In this paper, it will study on the main idea and content of each technology, in order to discover the new developing direction of procedural modeling design methods in the field of urban design.
