As point clouds typically are very large and data heavy some of the steps here are about reducing complexity. This operation can be extremely u Dec 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. Tutorial on how to use Meshlab to create meshes from point clouds. Therefore, to convert a mesh to a point cloud, you need to sample points on the surface of the mesh. Using your example I have found the reason for your troubles. xyz -o output_file. p_plane (centroid here) + p. ply" file format in Meshlab. Before importing make sure you do some pre-processing / cleaning on point cloud so as to ease the process of meshing. The window below .
