摘要

摘要: 针对逆向工程中的三角网格重构问题,提出了一种保持尖锐特征的半规则三角网格模型细分曲面重构算法,以充分利用细分曲面的多分辨特性.首先经提取尖锐特征和删除最大独立点集得到基网格,然后利用插值Loop细分和最近点法向投影法不断调整半规则网格得到重采样网格,最后运用渐进插值(PI,Progressive Interpolation)算法生成半规则细分曲面.实例表明,重构后获得的细分曲面连接性好,可以直接进行细分小波分析.

Abstract: Focusing on mesh reconstruction problem of reverse engineering, a subdivision surface reconstruction method to reproduce a semi-regular triangular mesh while preserving the sharp feature was proposed, which can make full use of the multiresolution analysis of subdivision surface. Firstly, the base mesh was created by removing maximally the independent set of vertices after the pretreatment. Then by employing the nearest point method on the normal direction projection and considering the Loop subdivision limited position mask, iterative vertices modifications were utilized to adapt the semi-regular mesh to fit the subdivision surface. Finally, experimental results were given to illustrate the effectiveness and efficiency of the proposed method.
