摘要
网格简化是计算机图形学中一个传统的研究课题,它对网格的存储和传输处理以及实时绘制都有着重要的意义。在视觉感知理论的指导下,提出一种新型的渐进网格简化算法,在简化过程中尽量保持视觉敏感的区域。依据半边折叠的能量函数来有效控制几何误差。实验表明,此算法不但可以生成一系列感知逼真的细节等级模型,而且具有很好的时间复杂性。
Mesh simplification is a classical research subject in computer graphics and is an very important significance for mesh storage, transmission process and real time render. In accordance with human vision theory, a new progressive mesh simplification algorithm was proposed. In the process of simplification, this algorithm keeps the most vision sensitive area. According to the energy function of half-edge collapse, this algorithm can effectively reduce geometry error. Experiment proves that this algorithm can generate a series of LOD (level of detail) model with perceptible fidelity and low time complexity.
