| Popis: | Computer generated graphical scenes benefit greatly from the inclusion of accurately rendered shadows. Shadows contribute to the realism of a scene, and also provide important information relating to the relative position of objects within a scene. However, shadow generation imposes a significant penalty in terms of the time required to render a scene, especially as the complexity of the scene and the number of polygons needed increases. For this reason, real-time scene generation would benefit from the use of a heuristical approach to the determination of shadow areas. In this paper, we introduce a number of heuristics that may be employed to facilitate real-time animation of objects with shadows at acceptable frame rates. We also present an application designed to investigate the feasibility of rendering shadows at varying levels of detail. |
