This is the official repository for the source and the binaries of MeshLab.

MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured large 3D triangular meshes. It is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.

MeshLab is mostly based on the open source C++ mesh processing library VCGlib developed at the Visual Computing Lab of ISTI - CNR. VCG can be used as a stand-alone large-scale automated mesh processing pipeline, while MeshLab makes it easy to experiment with its algorithms interactively.

MeshLab is available for Windows, MacOS, and Linux.


You can find the last MeshLab release in the Releases Tab for your favourite platform. You can also test a built version of MeshLab generated by the last commit pushed in this repository, by downloading the artifacts of the last Github Actions workflow.

Build instructions

We provide a set of scripts that build and deploy MeshLab automatically. All the scripts can be found in the scripts folder. For specific build instructions see the src folder.

Structure of the Repository

The MeshLab repository is organized as follows:

  • distrib
    : this folder contains a set of prebuilt libraries and shaders that will be used by MeshLab once it is compiled. For more details, check the readme here;
  • docs
    : doxygen scripts for generating MeshLab documentation. For more details, check the readme here;
  • sample
    : a set of files (meshes, images) used for tests;
  • scripts
    : in this folder there is a set of platform-dependent scripts to build and deploy MeshLab. For more details, check the readme here;
  • src
    : this folder contains all the source code of MeshLab, its plugins and the external libraries that it requires. For more details, check the readme here;
  • unsupported
    : this folder contains a set of old and unsupported MeshLab plugins that are no longer included and built under MeshLab.
