【摘要】 采用面积夹角加权的三角网格模型顶点法矢及三角片质心权值对Taubin的三角网格模型离散曲率计算方法进行了改进,在此基础上提出了一种新的三角网格模型优化调整方法。用该方法调整三角网格模型,在模型上曲率变化较平缓的平坦区域及曲率变化较剧烈的特征区域都能取得较好的调整效果。更多还原

【Abstract】 Based on the improvement of Taubin’s discrete curvature estimation method of triangular mesh by the adoption of area and angle weighted triangle vertex normal vector calculation formula and triangle centroid weights, a novel algorithm for triangular mesh regularization is presented. By this algorithm, good results can be achieved both in the flat regions with equable curvature changes and the feature regions with steep curvature changes of the regularized triangular meshes.更多还原
