MeshLab is an open source program for editing 3D triangle mesh files in various formats. It is used in 3D scanning and virtual reality applications.

MeshLab is a open source desktop program for editing 3-D triangle mesh files in various formats used in 3-D scanning and virtual reality. It was originally developed as a didactical experiment at the University of Pisa and is actively maintained at the Visual Computing Lab of the Italian National Research Council.

Windows, Linux, and Mac OS X versions are available at the MeshLab official site.

Its capabilities include importing and exporting 3-D triangular mesh files in various formats, mesh visualization, and mesh editing functions such as cleaning, painting, remeshing, selecting and deleting parts of the mesh, and colorization.

How to trim or orient the extra data Meshlab creates around a point cloud

I'm creating a point cloud by 3d scanning an arched guitar back, and am converting it in MeshLab to .stl to import into VCarve CAD. The first time I used a .25" grid which turned out to be too coarse, but otherwise the .stl file worked well. The…

Is it possible to script the MeshLab align function with point based gluing?

I need to make the ability to combine three meshes / point clouds easy to do in a graphical user interface. In MeshLab the "Align" function works perfectly using "Point Based Gluing" for combining the three meshes. But I can't find any script for…

Meshlab: mesh semplification with fixed patch size

All, I'm using meshlab to simplify the overall mesh of a given .STL model. Usually I make use of the embedded QECD algorithm. Nonetheless I'm not able to reduce the mesh imposing an upper-bound limit for faces dimension, that shouldn't exceed a…

2022.02 won't load 2D meshes, .ply format

I have some 2D triangle meshes in .ply format that both Blender and MS 3D Paint will open. But Meshlab (2022.02) will not. It gives the error message "No vertex field found". I would guess that means it wants 3D meshes only. Or could it be…

Blender add-on "3D Print Toolbox" and MeshLab

Blender software has a nice mesh analysis add-on called ”3D Print Toolbox". It is making us give it a second look for our 3D printing workflow. On the other hand, MeshLab is very nice to have mesh repair tools. I see the errors in the Blender, and…

Scale along normals

I'm trying to 'inflate' a mesh. I see that basically what I'm looking for is performed in Blender by scaling everything along the normals. Would there be a way to do this precisely (setting a precise percentage) in MeshLab?
