![]() This algorithm will add more detail to the mesh. This time distribute points by going to Filter > Re-meshing-simplification and reconstruction > Use sub-division algorithm called LS3 loop. Between 2 vertices - to connect vertices across multiple faces. Between many selected vertex pairs (you can connect multiple faces at once). Open MeshLab and load in the mesh: File Import Mesh Select your mesh To clean up your mesh, apply tools in Edit or Filters. Mesh -> Vertices -> Connect (menu) JKey (shortcut) While the knife can be used for this purpose too, for quick cuts this is faster. Now approximate more normals using the point cloud to add more detail. Though many 3D modeling software include such features, MeshLab has a more extensive and fleshed-out mesh decimation pipeline allowing for more control over mesh cleaning. Turn on the Light found within the tool bar and also turn on Smoothing which is next to the light button. Make the numbers bigger if the point cloud is big. Now go to Filters > Point Set > Surface Reconstruction: Poisson, set parameters, 12 for Octree Depth and 7 for Solver Divide, these numbers can be changed depending on the scale of the original point cloud mesh. obj file, which can be open with MeshLab. ![]() This will create an even sampling distribution of the cloud points, and will give a general surface to work with. meshsplit : split a mesh by inserting new vertices defined on mesh edges. Now create a subset of the point cloud, go to Filters > Sampling > Poisson -Disk sampling, change the Number of Samples to 5000 and check the box for Base Mesh Subsampling. Turn on layers from the top menu bar View -> Open Layer Dialog. Change the camera to -1000 so that the sampling program knows that the cloud point data was taken from a large distance, this would give it a better idea where the normals should go. Recompute normals using Filter > Point Set -> Compute normals for point sets, change number to 16 for the number of neighbors and also check the box for Flip Normals.
