MeshLab is an open source portable and extendible system for the processing of unstructured 3D triangular meshes.
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 cleaning, healing, inspecting, rendering and converting this kind of meshes.
The system is heavily based on the VCG library
developed at the Visual
Computing Lab of ISTI
- CNR, for all the core mesh processing tasks. The MeshLab system started as a part of the FGT
course of the Computer Science department
of University of Pisa and currently most of the developed code (~15k lines) is
authored by a handful of students.
The project is partially supported by the European Networks of Excellence Epoch and AimAtShape.
Whenever you use MeshLab in a official/commercial project, you should feel morally obligated to:
- cite in your work that you have used MeshLab,
- post a couple of lines in the users' forum describing the project where MeshLab was used.
Features
- Input/output in many formats (PLY, STL, OFF, OBJ, 3DS)
- Extendible plugins based architecture, writing new mesh processing functions, colorization filters and support for different file formats is quite easy (look at this code sample)
- Cleaning Filters:
- removal of duplicated, unreferenced vertices, null faces
- subdivision filters (midpoint, loop and butterfly)
- coherent normal unification and flipping
- OpenGL Shader based rendering (write you own shader!)
- Large rendering (up to 16k x 16k) for high quality printing
- Various Colorization Filters
- Gaussian and mean curvature
- Border edges
- Non two-manifold faces
General questions can be posted on the help public forums

A 10,000,000 face model successfully loaded and ready for inspecting. 3D Model of a Thai statue courtesy of XYZ RGB inc. provided by the Stanford 3D Scanning Repository. |

A textured ply model of the well known Michelangelo David, original mesh courtesy of Stanford Digital Michelangelo Project, texturing done by Visual Computing Lab ISTI - CNR through integration of photos taken during the Restoration of the David. |

A high resolution snapshot (4400x9110) taken with MeshLab of the 10 Mtri 3D model of the above cited Thai statuette. The snapshot is a 17Mb png, so you can download it using the sourceforge file distribution system. On the right you can see a very small portion of the orginal sample just to give you an idea of the quality of a 40 Mpix image. |

An high resolution rendering (3200x6424) taken with MeshLab of the 8 Mtri model of the Michelangelo David. Original mesh courtesy of Stanford Digital Michelangelo Project. The model is interactively rendered using a pre-computed ambient occlusion term computed with the open source ShadeVis tool. On the right you can see a very small portion of the original rendering just to give you an idea of the quality of the original 20 Mpix image. |
