我们提出了一种方法,用于设计光滑的表面上的交叉领域,自动对齐到底层几何形状的尖锐特征。我们的方法引入了一类新的能量的基础上表示的交叉领域的球谐基础。我们提供了理论分析,这些能量在光滑的设置,表明他们惩罚偏离表面折痕,而以其他方式促进本质上光滑的领域。我们证明了我们的方法的适用性,四网格,包括一个广泛的基准比较我们的领域,其他自动生成功能对齐的交叉领域的三角形网格的方法。
We present a method for designing smooth cross fields on surfaces that automatically align to sharp features of an underlying geometry. Our approach introduces a novel class of energies based on a representation of cross fields in the spherical harmonic basis. We provide theoretical analysis of these energies in the smooth setting, showing that they penalize deviations from surface creases while otherwise promoting intrinsically smooth fields. We demonstrate the applicability of our method to quad meshing and include an extensive benchmark comparing our fields to other automatic approaches for generating feature-aligned cross fields on triangle meshes.
