Webquality of simplified mesh also plays much importance. In this paper, we present a novel GPU-based mesh simplification algorithm, which takes both the speed and mesh quality into ac-count. The method runs entirely on GPU and collapses multiple edges in parallel. Data transfer between CPU and GPU is minimized. WebIterative Edge Contraction. Several algorithms have been published that simplify models by iteratively contracting edges (see Figure 1). The essential difference between these algorithms lies in how they choose an edge to contract. Some notable examples of such algorithms are those of Hoppe [4, 3], Ronfard and Rossignac [7], and Gu´eziec [2].

WebComputing a coherent mesh layout is reduced to a combinatorial optimization problem. We designed and implemented an out-of-core multilevel minimization algorithm and tested its performance on unstructured meshes composed of tens to hundreds of millions of triangles. Our layouts can significantly reduce the number of cache misses. Webresolution mesh simplification algorithms refine or simplify meshes globally based on the distance to the view point and projected area on the screen. They are called continuous LOD [3, 4]. Continuous LOD allows a geometric model to be efficiently delivered over a network in a progressive manner. Compared to
