本文提出了一种在各种用户需求下生成高度规则的三角形网格的新颖算法。首先在输入网格上计算三个标量场。然后,使用它们的等值线彼此的交点来构建高度规则的网格结果。该算法利用N-对称方向场来引导边缘方向。尺寸控制是通过在表面上使用密度函数来实现的。所有用户需求都被纳入标量场的能量优化框架中,然后使用生成的标量场的等值线来构建满足所有需求的高质量结果。实验结果表明,该方法能够成功处理各种用户需求和复杂形状。
This paper presents a novel algorithm for generating a highly regular triangle mesh under various user requirements. Three scalar fields are first computed on the input mesh. Then, the intersections of their isocontours with one another are used to construct the highly regular mesh result. The proposed algorithm uses theN-symmetry direction field to guide the edge orientation. Size control is achieved by using a density function on the surface. All user requirements are incorporated into an energy optimization framework of the scalar fields, and then the isocontours of the generated scalar fields are used to construct a high quality result that satisfies all requirements. The experimental results show that the proposed method can successfully handle various user requirements and complex shapes.
