Automatically generating roof models from building footprints

Abstract

Modelling Large Urban Environments using traditional modelling techniques would prove too time consuming a\nprocess. Consequently a method is required for generating large urban environments quickly without requiring a\nlabour intensive process or expensive data. Some approaches to resolve this problem have been undertaken\nthrough the use of procedural modelling or statistics. However the test subject is usually a dense urban\nenvironment where the primary buildings are of the skyscraper style. This paper presents the initial design and\nimplementation towards a method for modelling a large environment based on building footprint information. It\nshows the use of the straight skeleton method with modifications to allow several different roof styles to be\ngenerated.
