Abstract
This paper describes the use of computer graphics modelling and
rendering techniques for the construction of a virtual environment
corresponding to a real scene of crime. The aim of the project,
conducted in collaboration with the ComputerExaminations Unit of the
Greater Manchester Police, was to evaluate the utility of virtual
environments for scene of crime analysis, briefing and training.
We present an illustrated case study of the construction of a virtual
environment, intended to match a real-life scene as closely as
possible. We describe and evaluate the combination of several
approaches including: the use of the the Manchester Scene Description
Language for constructing complex geometrical models; the application
of a high-quality radiosity algorithm with several novel features
based on human perceptual considerations; texture extraction from
forensic photography; and experiments with interactive walkthroughs
and large-screen stereoscopic display of the virtual environment.
