Abstract
Abstract A method of generating dynamically altering images which are capable of simulating fluid effects in real-time on a static scene. The method includes the steps of loading a plurality of graphical components, and repeatedly applying each of these graphical components to a texture map in a sequence of toroidally incremented locations at a predetermined repetition rate to create a texture map overlay for each of a plurality of scene frames. Each of these toroidally incremented locations are determined by a non-linear combination of a linear offset vector and the location of the last graphical component that has been applied. Then, each of the plurality of scene frames are transmitted to a visual projection device at a predetermined frame rate in order to display the dynamically altering images.
