Abstract:

Virtual building modeling became an increasingly urgent need for computer graphics, simulation, games, films and virtual reality. However, this is an exhaustive task and requires much more time and effort. There are many researches, which state this problem, but most of them concentrate on grammar-based generation. Grammar-based generation researches require more time to learn and are not suitable for non-qualified users. Our paper presents a new framework to generate automatic and extensive 3D solid building models procedurally relying on a set of methods called modules; these modules are offset, ellipse, Lsystem, smoother, polygon reduction, polygon division, transformation, and extrusion. Our building model can be created either automatically or semi-automatically. Each building model consists of some or all of our modules, these modules are specified either by an automatic model generator or by users to create a special model (using the wizard or writing an xml file). Model modules declare how the building footprints, floors and geometries will be generated. Our framework generates different building models using the same modules with different parameters’ values, while the modules remain small and simple, which means less time to learn and enables non-technical users to create wonderful solid building models. Our framework can generate trivial and non-trivial buildings’ types according to certain rules.
