Jan 5, 2021 · 拉普拉斯平滑（Laplacian Smooth）： 最基础的平滑，其他的平滑都是在拉普拉斯的基础上改进的。 最为基础的拉普拉斯平滑算法的实现，简单的拉普拉斯平滑算法的原理是将每个顶点都移动到相邻顶点的平均位置，即采用所谓伞状算子。 1. cpp, where I can see that it is calling to method vcg::tri::Smooth::VertexCoordLaplacianHC() Beta is 0. 初始化Mesh的邻接点结构集 2. The following features have been implemented in this assignment: Laplacian mesh editing (Umbrella and Cotangent weights; Color interpolation; Smoothing and . The latter method of weighting attempts to correct for the uneven resolution of the mesh. the meshlab smoothing filters has exactly the behavior you described: - Laplacian Smoothing, HC smoothing, Two step smoothing all of them, neither change the topology of the mesh nor add/remove vertices or triangles, they only move the coords of the vertices of the mesh.
