摘要
网格简化是曲面重构和多细节层次构造中的一个重要步骤，本文提出了一个基于局部能量评估的网格简化算法，能够大量地删除密集网格的三角形面片．为了加速算法的执行还提出了一种简单有效的采样方法．算法自动化程度高，能有效地支持多细节层次模型的建立．
Mesh simplification is an important stage in the surface reconstruction andthe generation of multiple LOD(level of detail) models. In this paper, the authors presenta tnesh simplification algorithm based on energy evaluation which can effectively reducethe number of triangles in a dense mesh. This algorithm is able to decimate the mesh whilewell keeping the original topological type of the mesh, and to evaluate the error of meshfitness according to the energy value, To accelerate the algorithm, a simple effective sam-pling method is employed. In addition, this algorithm is highly autornatic to support theconstruction of the LOD models.
