MeshLab is an open source portable and extendible system for the processing and editing of unstructured 3D triangular meshes. The system relies for mesh processing tasks on the gpl VCG library (
The system 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.

  • Interactive selection and deletion of portion of the mesh. Even for large models.
  • Painting interface for selecting, smoothing and coloring meshes.
  • Input/output in many formats:
  • import:PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX
  • Mesh Cleaning Filters:
  • removal of duplicated, unreferenced vertices, null faces
  • removal of small isolated components
  • coherent normal unification and flipping
  • erasing of non manifold faces
  • automatic filling of holes
  • Remeshing filters:
  • High quality edge collapse simplfication (even meshes with texture coords preservation)
  • Surface reconstruction from points (a ball pivoting variant)
  • Subdivision surfaces (loop and butterfly)
  • Feature preserving smoothing and fairing filters
  • Various Colorization/Inspection filters
  • Gaussian and mean curvature
  • Border edges
  • Non two-manifold edges
  • Self intersecting faces
  • Interactive Mesh Painting
  • Color Painting
  • Selection paint
  • Smoothing
  • OpenGL Shader based rendering (write your own shader!) compatible with Typhoon Lab´s Shader Designer
  • Large rendering (up to 16k x 16k) for high quality printing
  • The history of the all performed cleaning/editing actions can be re-played on different meshes or saved and for archival purposes.
  • Extendible plugins based architecture, writing new mesh processing functions, colorization filters and support for different file formats is quite easy!

What's New
  • Point Cloud management, now you can select and delete individual vertices in point clouds.
  • Added exporting of .m LiveGraphics3D format, a simple format that allow the quick and easy insertion of 3D
  • Added measuring filters for assessing geometric (mass, inertia tensor, baricenter, surface area etc) and topological measures.
  • Fractal generation stuff, and filters for perturbing the surface of an object with various kind of fractal noise
  • Persistent preferences, for saving options from a session to another
  • Yet another surface reconstruction algorithm. This time it is our own internal tool that have been massively used for years and that we decided to release under GPL. More on this on the blog.
  • vastly improved the speed and robustness of isoparametrization and ball pivoting filters
  • many new texture managment tools for building trivial parametrizations and converting color data from and to different representations (vertex color texture)
  • shadow mapping and screen space ambient occlusion decorators
  • added previewing capabilities to many filters
  • filters for performing aggregate statistics over quality distributions on a mesh
  • rearranged many of the cleaning filters into selecting tools to allow a better control of the process
  • Improved support of polygonal meshes in many places added three filters to generate basic quad meshes from triangle meshes.
