MeshLab

An extendible system for the user assisted 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 and healing 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 task.
The Meshlab system started as a part of the FGT course of the Computer Science department of University of Pisa.

Features

Input/output in many formats (PLY, STL, OFF, OBJ)
Extendible plugins based architecture, writing new mesh processing functions, colorization filters and support for different file formats is quite easy.
Cleaning Filters

Removal of duplicated, unreferenced vertices, null faces

Subdivision filters (loop and butterfly)

Opengl Shader based rendering
Large snapshot for hi quality printing
Various Colorization Filters

Gaussian curvature

Border edges
Non two-manifold faces

	A textured ply model of the well known Michelangelo David, original mesh courtesy of Stanford, texturing through photo integration by Visual Computing Lab ISTI - CNR
	A model with self intersecting faces detected by MeshLab colored in red.
	A model with border edges colored in blue.
	A high resolution snapshot (4400x9110) taken with MeshLab of the 10 Mtri 3D model of the 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.
