摘要
三角网格曲面的参数化是纹理映射、重新网格化和曲面拟合过程中的重要环节,因此在实践中采用的参数化方法合适与否至关重要。本文着重介绍了三种代表性参数化方法,对这三种方法作了详细的分析和比较,给出了各算法的特点、运行时间、纹理映射效果和映射前后三角片的变形大小,对参数化方法的实际应用有一定的指导作用。
Parameterization of surface triangulation is essential for operations such as texture mapping, remeshing and surface fitting. It's very important for finding a better parameterization in practice. In this paper,three typical methods are introduced and tested on triangular meshes, and then the characteristics of the three methods,are analyzed and compared by runtime, texture mapping and distortion. It's very helpful for application of parameterization.
