AI总结:

本文基于Young-Laplace方程和力平衡原理,推导出三角表面网格顶点的平均曲率法向量近似表达式,并证明其与文献中离散拉普拉斯-贝尔特里算子方法等价,为计算平均曲率法向量提供了新方法,可扩展至非三角和异质网格结构。

摘要:

在本文中,我们从Young-Laplace方程和力平衡原理出发,推导出三角表面网格顶点的平均曲率法向量近似表达式。然后我们证明了基于物理推导的近似表达式与文献中离散拉普拉斯-贝尔特里算子方法是等价的。本文不仅提供了计算平均曲率法向量的另一种表达式,还可以进一步扩展到其他网格结构,包括非三角和异质网格。

英文摘要:

In this note, we derive an approximation for the mean curvature normal vector on vertices of triangulated surface meshes from the Young-Laplace equation and the force balance principle. We then demonstrate that the approximation expression from our physics-based derivation is equivalent to the discrete Laplace-Beltrami operator approach in the literature. This work, in addition to providing an alternative expression to calculate the mean curvature normal vector, can be further extended to other mesh structures, including non-triangular and heterogeneous meshes.
