Simulation
from the imaginary to the real
For centuries humans have used various tools and methods of simulation and visualisation for training, testing, modelling and making predictions. Simulation is the imitation or representation of events and processes; visualisation uses graphic representation of data to enhance our understanding of and thinking about the world.
Computers are a very powerful new tool in these fields. So compelling are the experiences and images which they can provide that the distinction between the real and the virtual is sometimes lost. But, just as ‘the map is not the territory’, our choice of visualisation can constrain our understanding.
Why use computers to simulate
The ultimate in make believe
The ability of computers to receive multiple signals, process mathematical data, present images and sounds and control external devices makes them ideal simulators for purposes such as training. Computers can combine mechanical, functional and aerodynamic data to create a replica of the workings and operations of an aircraft. This craft can then ‘fly' in a virtual world that can be based on some part of the real world. Today's flight simulators are perhaps the most advanced virtual reality systems in existence.

The transparent plastic woman was used as a training aid to show how the body worked. Computers that now allow us to fly through the body or conduct surgery have replaced the need for such devices. Powerhouse Museum collection.
The WEDGE Technology today allows
us to see and interact with images
that appear to be three-dimensional
and to exist in space. These images
can represent enormous amounts of information that would otherwise be difficult or impossible to comprehend. Click image to launch exhibition panorama - requires Quicktime
