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 system is heavily based on the VCG library developed at the Visual Computing Lab of ISTI - CNR, for all the core mesh processing tasks and it is available for Windows, MacOSX, and Linux. . 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 of the first versions was written by a handful of willing students. The following years FGT students have continued to work to this project implementing more and more features.
Features
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, V3D, PTS, APTS, XYZ, GTS, TRI, ASC, X3D, X3DV, VRML, ALN
export:PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF, GTS, U3D, IDTF, X3D
Point Clouds support. Now 3D files that are composed only by points are well supported in PLY and OBJ format.
U3D support; MeshLab is the first open source tool to provide direct conversion of 3D meshes into the U3D format. Now you can create pdf, like this with 3D objects with just
MeshLab and LaTeX.
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
High quality edge collapse simplification (even with texture coords preservation)
Surface reconstruction from points (a ball pivoting variant, marching cubes and poisson's reconstruction)
Subdivision surfaces (loop and butterfly)
Feature preserving smoothing and fairing filters
Holes filling
Various Colorization/Inspection filters
Gaussian and mean curvature
Border edges, geodesic distance, from borders
Non two-manifold edges and vertices
Self intersecting faces
Ambient Occlusion. An ambient occlusion field can be computed and stored per vertex
Interactive Mesh Painting
Color Painting
Selection paint
Measuring tool. You can take linear measures between points of the displayed meshes
