| Fast Event-Driven Refinement of Dynamic Levels of Detail (2003) | |||||||||||||||||
Abstract | |||||||||||||||||
| Dynamic levels of detail allow fine grained selection of actually rendered geometry suitable for the current viewing parameters. Therefore, the visual quality of interactive 3D applications is usually higher than the quality achieved by traditional static level of detail approaches. On the other hand, this fine grained representation requires more CPU time for runtime refinement of the displayed mesh. We report on an event-driven refinement method that decreases the selection time significantly. Our approach exploits coherence between successive frames explicitly to reduce the number of tests necessary for node refinements. For large virtual environments we observed, that our method performs best when the actually displayed mesh is very complex. In these cases our approach is several times faster than the primal methods for dynamic level of detail refinement. | |||||||||||||||||
