Meshlab is a tool that allows you to process and edit 3D objects.
It began to be developed in Visual Computing Lab of ISTI-CNR in 2005 by a group of Students. Development is actively supported by the 3D-CoForm project.
The last version is the 1.3.3 of April 2014.
Meshlab is hosted on sourceforge


Meshlab has the following features:

  • Interactive selection and elimination of parts of the network. Even in large models
  • Paint interface for selecting, smoothing and coloring the nets
  • reading and writing various 3D formats:
      - Import from: PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX, V3D, PTS, APTS, XYZ, GTS, TRI, ASC, X3D, X3DV, VRML, ALN
      - Export to: PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF, GTS, U3D, IDTF, X3D
      - Support for Point Clouds. 3D files that are only composed of dots are supported in PLY and OBJ formats.
      - Support U3D; Meshlab is the first open source tool that provides direct support for converting 3D network into U3D format. Now you can create PDFs, only with Meshlab and LaTex.
  • Cleaning filters:
      - removal of duplicate, unreferenced vertices and null faces.
      - removal of small isolated components
      - normal, coherent and changed unification.
      - non-manifold face cleaning.
      - automatic filling of holes
  • Replacement filters (remeshing):
      - High-quality simplification of border collapsing
      - Reconstruction of surfaces from points
      - Subdivision of surfaces (cycle and butterfly)
      - smoothing maintenance and correction filters
      - Filling holes
  • Various paint / inspection filters:
      - Gaussian and Median Curvature
      - edge tips, geodesic distance, from the edges
      - tips without 2 “manifolds” and vertices
      - self-intersecting faces.
      - ambient occlusion
  • Interactive Network Painting:
      - Color Painting
      - Painting selection
      - Smoothing
  • Measuring tool.
  • Snipping tool
  • 3D scanning tools:
      - ICP alignment based on interval maps
      - Junction of multiple networks through the reconstruction of the surface “Poisson”
  • rendering based on OpenGL Shader
  • Large rendering (up to 16k x 16k) for high quality printing.
  • Command history system can be re-run on different or recorded networks.
  • Extensible Plugins architecture, allowing to create new functions for network handling, paint filters and support for other file formats.
