## What it is
MeshLab is an open source, portable, and extensible system for processing and editing unstructured large 3D triangular meshes, built on the VCGlib C++ library. It provides interactive tools for editing, cleaning, healing, inspecting, rendering, texturing, and converting meshes arising from 3D scanning and digitization.

## Use cases
- clean and heal noisy 3D scan data
- simplify large triangular meshes
- convert 3D models between file formats
- prepare models for 3D printing
- inspect and measure 3D mesh geometry
- process point clouds from 3D digitization devices
- remesh and repair broken 3D models
- texture and render 3D scanned models

## When to choose
- you need to clean, repair, or simplify 3D scanned meshes interactively
- you work with large unstructured triangular meshes or point clouds
- you need a free cross-platform tool to convert many 3D file formats
- you want to prepare and check models before 3D printing
- you want scriptable mesh processing via PyMeshLab

## When to avoid
- you need parametric CAD modeling or solid modeling features
- you want to sculpt or paint 3D models artistically
- you need a lightweight command-line-only pipeline without a GUI
- you require permissive licensing since MeshLab is GPL-3.0
