ABSTRACT:
A method of displaying an object in a real-time simulation using silhouette load mangement techniques, whereby a minimal number of polygons is used in the display process. Two-dimensional silhouettes are created by taking snapshots of three-dimensional models at various angles of view. These silhouettes are stored in texture memory. The appropriate silhouette is selected for display depending upon the angle from which that object is viewed. As the angle of view changes, a different silhouette is selected for display. Once a threshold, such as the angle of rotation or the distance from the viewer, has been reached, the three-dimensional model is substituted for the silhouette for display.
