MeshLab is an open source portable and
extendible system for the processing and editing 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 editing, cleaning, healing, inspecting, rendering and
converting this kind of meshes.
The project is supported by the European Network of
Excellence Epoch
and Aim@Shape
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 in late 2005 as a part of the FGT course of the Computer Science
department of University of Pisa and most of the code (~15k lines) of the first
versions was written by a handful of students. Also this year FGT students has continued to work to this project implementing new features.
The proud MeshLab developers are listed below.

Remember that, whenever you use MeshLab in a official/commercial project, you should :
- Explicitly cite in your work that you have used MeshLab a tool developed with the support of the Epoch NOE,
- Post a couple of lines in the users' forum describing the project where MeshLab was used.
Features
- Interactive selection and deletion of portion of the mesh. Even for large models.
- Input/output in many
formats:
import:PLY, STL, OFF, OBJ, 3DS, COLLADA, PTX
export:PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF - 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 small holes
- Remeshing filters:
- High quality edge collapse simplfication
- Surface reconstruction from points (a ball pivoting variant)
- Subdivision surfaces (loop and butterfly)
- Smoothing and fairing filters
- Various Colorization/inspection filters
- Gaussian and mean curvature
- Border edges
- Non two-manifold edges
- Self intersecting faces
- 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! Look at Filter-PlugIn Sample or MeshIO-PlugIn Sample

ScreenShots
| Snapshots taken from MeshLab v 0.9 | |
|
An example of the improved hole filling algorithm. Holes with irregularly shaped borders can be successfully closed with (possibly) non self-intersecting patches. |
| Snapshots taken from MeshLab v 0.8 | |
   |
An example of automatic noise removal. A mesh with some random noise (left) is smoothed twice (center and right) using a feature preserving two-step smoothing algorithm. |
  |
An example of automatic hole filling. All the holes with a boundary smaller than a given threshold (30 edges in this case) are autmatically filled. |
   |
An example of the high quality edgecollapse simplification algorithm based on quadric error metrics. A ~1.000.000 triangle mesh (left) is simplified to 100.000 (center) and then up to 10.000 triangles, while maintaining most of its geometric features. |

One example of real time NPR rendering using a hatching style implemented through a OpenGL shader. The shader was used to create the high res snapshot (2282x2942). |

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. |
