This paper briefly describes the software application OmniVista written for the Apple Macintosh Platform. OmniVista is essentially an isovist generating application, which uses the 2d plan of a building or urban environment as input data, and then can be used in one of three modal ways. Firstly, point isovists can be generated by 'clicking' onto any location in the environment. Secondly, all navigable space can be flood-filled with points, which may then beused to generate a field of isovists. Finally, a path of points can be used to examine how isovist properties vary along the path - the results of this can either be output as numerical data, or exported as a series of pictures, which may be combined to form an animation of the varying isovists along the route. This paper will examine all three modes of use in turn,starting from the simplest (point) to the more complex (the path). A description and equation for all isovist measures used in the application will also be given as an appendix to the paper.
