Fast modeling of vernacular houses of South-east China

The modeling of large-scale vernacular houses in South-east China is a challenging work. In this paper, we implement an urban modeling system, using a production-based recursion grammar system to generate all the vernacular houses and the arrangement of the urban district. This grammar system is found on the basic elements of the vernacular houses' components, such as windows, gates, walls, roofs etc, which is regarded as a term in productions. Furthermore, to avoid the disadvantage (hard to control) of the grammar system and to ensure the coherent architecture styles of ancient vemacular houses, we also design a verifying system, which can check out those invalid house combination and regenerate them.
