Executive Summary

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. The 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. The building model can be created either automatically or semi-automatically.
