摘要
在以往的网格简化算法中,大多是采用空间几何距离作为简化准则.几何距离能很好地控制简化后的网格与原始网格之间的误差,但在保持形状特征上相对较弱.本文提出的网格简化算法是根据网格顶点的曲率,采用边折叠的方式来减少低频区域的网格顶点密度.由于曲率能很好地刻画网格形状,故本文的算法能较好地保持原始网格的形状特征.
Most of the simplification algorithms use a distance metric as simplification criteria. The distance metric is good to measure geometric errors between original mesh and the result, but it is not good for preserving the shape of the original model. This paper proposes a mesh simplification algorithm based on vertex's curvature, which use edge collapse method to reduce the density of low-curvature region of meshes. As the curvature is useful to enhance the shape description, the shape of the model can be preserved well after our simplification process.
