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. Meshlabs real work is done by Meshlab filters, which are DLLs or shared objects written to comply with a documented standard interface. Now approximate more normals using the point cloud to add more detail. 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.

This will create an even sampling distribution of the cloud points, and will give a general surface to work with. Instructor For this weeks tip, Im going to be showing you how to reduce the file size of an imported mesh model using MeshLab. Next, choose the second mesh and click on Point Based Glueing. This will affix the mesh to a set location and allows the other meshes to be aligned to it. Click on the first mesh file in the menu and choose Glue Mesh Here. 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. This tool is used to reposition the separate meshes in relation to each other. 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.
