WebFarthest point sampling is a greedy algorithm that samples from a point cloud data iteratively. It starts from a random single sample of point. In each iteration, it samples from the rest points that is the farthest from the set of sampled points. class dgl.geometry.farthest_point_sampler [source] WebDec 1, 2014 · Conversion from a mesh to a point cloud is not similar to jamming the mesh's vertices into a point cloud! Mesh is a sparse representation of a point cloud. Therefore, to convert a mesh to a point cloud, you need to sample points on the surface of the mesh. PCL has a utility for doing that called pcl_mesh_sampling. The source code is located here.
