MeshLab

MeshLab is a system for processing and editing large, unstructured 3D triangular meshes. It targets the messy models that come out of 3D scanning, giving you tools to edit, clean, heal, inspect, render, and convert that kind of geometry.

It is built on the VCGlib mesh processing library, so you can experiment with its algorithms interactively in the application while the same library can drive large-scale automated pipelines. The result is a portable, extensible workbench for repairing and preparing scanned models.

MeshLab runs on Windows, macOS, and Linux, with both stable releases and frequently updated development builds available for download.
