带尖锐特征的Loop细分曲面拟合系统

Fitting System Using Loop Subdivision Surfaces with Sharp Features

实现了一个基于带尖锐特征的Loop细分曲面的三角网格拟合系统,其基本原理来自文献[15],但在系统设计层面对原算法作了相当大的补充和完善.整个系统框架包括尖锐特征提取、保持尖锐特征的三角网格简化、保持尖锐特征的网格平滑和拓扑优化、基于最近点策略的重采样和线性拟合系统求解.所得到的拟合曲面质量较原来的结果有了显著提高.

A fitting system is developed to fit triangular meshes using Loop subdivision surfaces with sharp features. The system is based on a method described in reference [15], but it substantially enhances and consummates the original algorithm for practical implementation. The entire framework includes sharp feature extraction, mesh simplification, mesh smoothing, topological optimization, resampling and solution of the fitting system. Experiments demonstrate that the presented system can considerably improve the quality of the fitting surfaces.
