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 select multiple layers in Meshlab

I have 20 layers of obj files. I want to set part of them visible while others invisible. It's not convenient to set it one by one. Is there a easy way to select multiple layers at the same time and change their visibility.

COLMAP photogrammetry: Reconstruction gives only point cloud, no mesh

I've been trying to use COLMAP to produce 3D meshes from photographs, but all I can get is useless point clouds. I've studied various YouTube tutorials, but the results I get differ from what I am seeing, mainly in that I can never get a solid 3D…

Can I use meshlab to make a turntable animation from a .ply file?

I have no problem importing the file, I just am unsure if meshlab is the right program to make this animation. I essentially just want a gif or a video file that rotates a 3D object in the x-plane and then in the y-plane.

Calculate accurately the total number of vertices and faces in Wavefront .obj file in Python?

Dragging a 3D object as .obj file (Wavefront .obj file) to MeshLab or any other 3D graphics tells you the exact total number of faces and total number of vertices the model has. Vertices could be triangular or polygonal. Is there any way to…

Hollow out model for 3d printing

The latest version of Meshlab claims it has the functionality to hollow out models for 3d printing. I've looked through all the menus trying to find this feature without any luck. Anyone have any idea where this functionality is?

How to measure average distance between neighbors for a point cloud in MeshLab

I am trying to mesh a point cloud, and calculate Gaussian and Mean curvature. I am using Meshlab. I am trying to measure the average point cloud density, to be used in measuring curvature (APSS). The function "Radius from density" of a point cloud…

mesh decimation in python

I have a high resolution triangular mesh with about 2 million triangles. I want to reduce the number of triangles and vertices to about ~10000 each, while preserving its general shape as much as possible. I know this can be done in Matlab using…

Meshlab / Meshlabserver - How to detect the normal orientation of loaded .ply?

I have many .ply files. With some reasons, some of their normal orientations are pointing outside of the object(which is what I want) and some of them are pointing inside the object. Does Meshlabserver has a function that can detect the normal…

3d-printing an inherently nonorientable surface

I'm trying to print 3D models of nonorientable surfaces: Klein bottle, Kuen surface, Boy surface, etc. From the surface's parametric representation (x,y,z as functions of u and v) I compute a triangular mesh, which is mostly repairable into…

Getting edge points from a 3D model (mesh)

I want to find the sharp edges of any given mesh. For reference, here is a mesh of a chair: It's clear that the border of the back of the chair is an edge, as are the four curves that outline the arms and legs, etc. I would like to sample points…

How to correctly export a mesh as a .obj using "export mesh as" ?- unable to get a file with the textures

I probably gave too much detail here - but I am really stuck and can't find documentation to a seemingly simple process: I use Meshroom to create a 3D model and it saves it as 3 files: texturedMesh.obj, texturedMesh.mtl and a texture_1001.png. I…

Render meshlab scene to image

Is it possible to render a meshlab scene to an image, like taking a screenshot? I ultimately want to do this programmatically. Specifically I'm after something that allows it to be done via MeshlabServer's API.
