It does this by choosing a random first point and then choosing the point farthest away from the current point.

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.
