ENVIRONMENTAL VISUALISATION

1. TOOLS

2. APPLICATIONS

Environmental Visualisation describes my current research interests and has four major components:

• Using interactive visual display of planning data and options to assist design and decision processes
• Generation of realistic visual imagery for communication of options to the public
• Research into public perceptions and choices using virtual environments
• Use of visualisation tools to predict the effect of environmental changes on peoples attitudes and behaviour

Generation of realistic imagery

• static
• animated
• interactive
• multisensory

There are several areas of theory which should be understood before embarking on projects in visualisation. These include: colour and colour generation, , 3D data representation and transformation, visible surface identification , lighting models, and texture mapping.

Recent studies on the validity of computer simulated environments have also considered the effect of sound simulation on the sense of realism generated.

More recently I have been working with tools for interactive simulation. These have more promise as effective virtual environments since they allow the user to explore as they might in the real world.

Behaviour in virtual environments

Most recently I have been doing experiments design to provide rapid visual interpretation for use in environmental behaviour modelling - e.g. autonomous agents.
