Incorporating legal rules on procedural house generation

The increasing demand for larger and more complex virtual models arising from different areas (e.g. design of virtual cities, video games and computer animated movies) creates the need for efficient computer algorithms able to generate them automatically. This paper presents a method for automatic generation of traversable houses, using architectural legal rules and an L-system to generate a list of interior rooms. The method is established with a framework specifically conceived to generate 2D floor plans and 3D models which allow the generation of multiple houses and interactive navigation.
