View-Dependent Topology Simplification

摘要: We propose a technique for performing view-dependent sim­plifications level-of-detail-based renderings of complex models. Our method is based on exploiting frame-to-frame coherence and tolerant various commonly found degeneracies in real-life polygonal The algorithm proceeds by preprocessing the input dataset into binary tree vertex collapses. This used at run time to generate triangles display. Dependencies avoid mesh foldovers manifold regions object are stored an implicit fashion. obviates need any extra storage dependency pointers suggests potential application external memory prefetching algo­rithms. also distance metric that can be unify geometry genus simplifications with parameters such as viewpoint, view-frustum, local illumination.
