Simulated movement over terrain

摘要

A method for simulating the movement of a vehicle over a terrain is disclosed. The terrain is divided up into polygonal areas (in this case triangles) each associated with a graphical image or scene. The data for the whole terrain is stored in a database (106) of the individual mosaic s or tiles of the terrain. The method predicts the future position of the vehicle based upon its current position (108) and velocity (110) and selects likely cells from which the next scene frame will need to be generated. The image data corresponding to these predicted scenes is then passed to a processor (104). The method is applied to a video game driving simulator in the example given, to provide an animated graphical display. The advantage is that the use of a predictive position speeds up the process of providing images for display.
