Meshlab

MeshLab is 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 tasks. The Meshlab system started as a part of the FGT course of the Computer Sciencedepartment of University of Pisa and currently most of the developed code is authored by a handful of Master Thesis students.

The project is partially supported by the European Networks of Excellence Epoch and AimAtShape.

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 the 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
Large snapshot for high quality printing
Various Colorization Filters

Gaussian and mean curvature

Border edges
Non two-manifold faces

	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.

 General issues
  - Switched to qt4.1
  - Corrected Trackball panning
  - Safer initialization of color data
  - Better memory management (removed HUGE memory leaks...)
  - Meshlab icon and logo
  - About plugin Dialog

* Plugin System
  - Filters:
      Invert Faces
  - Colorize:
      Logging mesh curvature info
      Rewritten code to follow coding conventions
      Mean Curvature
      Color non Manifold (now sets colorPerVert)
      Moved mean and gaussian curvature functions into color_curvature.h 
  - Normals restyled
  - Import/Export:
      Managing error messages if saving fails
      .3DS Imporer first rough implementation
      .3DS Export Standardization, saves vertexes and faces + color per face
      .3DS Export introduced materials managing
      .OBJ Import solved some bugs during file import
      .OBJ Export higly improved speed

  
* User Interface
