A general purpose, easy-to-use graphical visualisation tool has been developed to facilitate the display of experiment data. It supports simultaneous or selective rendering of surfuces, graphs and animated traces in a virtual 30 environment. It can accept as many as 100,000 objectsfor animated replay, and allows for interactive control of viewing position, lighting and other display parameters. The viewer is thus well suited to scoping expeviment results, visually debugging data processing algorithms, andpresenting conzplex data. Its principal application is in the visualisation of surfaces and graphs in the entropy analysis of medical and industrial related time-series.
