摘要

法向网格是受微分几何启发的一种新的基本曲面描述。法线网格是一种多分辨率网格，其中每个级别都可以写入从粗版本的法线偏移量。因此，网格可以存储为每个顶点一个浮点数。我们提出了一种用法向半规则网格任意逼近任意曲面的算法。法线网格在许多应用中都很有用，比如压缩、过滤、渲染、纹理和建模。

Normal meshes

Normal meshes are new fundamental surface descriptions inspired by differential geometry. A normal mesh is a multiresolution mesh where each level can be written as a normal offset from a coarser version. Hence the mesh can be stored with a single float per vertex. We present an algorithm to approximate any surface arbitrarily closely with a normal semi-regular mesh. Normal meshes can be useful in numerous applications such as compression, filtering, rendering, texturing, and modeling.
