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 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

What is new in this release:

• This is a major release that introduces many new important features. Notably, the management of point clouds was significantly improved.
• Import from photosynth datasets has been added, together with unified management of raster data.

What is new in version 1.2.1:

• New features:
• Added color-per-vertex and color-per-face support to U3D and IDTF file formats
• Added Convex Hull, Alpha shape, Voronoi Filtering, and Visible points filters
• Added Decoration filter to show camera position
• Added Reflection Lines Shader to simply evaluate the mesh curvature. Notable bug corrections (since 1.2.0)
• Avoided crash in all filters based on marching cubes algorithm
• Substituted old IDTFConverter for Leopard with the new one provided by Michael Vidiassov (THANKS!)
• Added missing IDTFConverter's dll file to Windows Installer.
• Camera's parameters check box in SaveMaskExporter dialog is only visible when you can actually save the parameters' values.
• Improvements:
• Now U3D plugin has its autogenerated form, like others io filters
• Added Help option in SaveMaskExporter dialog to visualize the IO parameters' help info.

What is new in version 1.2.0:

• New features Easy Segmentation tool. A tool to easily select portion of a mesh by simply interactively sketching over it. Quality Mapping Tool. A editing tool and a filter for the fine tuning of how scalar values, defined over a mesh, are mapped into colors. Essential for creating correct images for scientific publications. X3D import and export and VRML import support support of the *.TRI meshes (meshes from the group of Departement TSI Signal-Images). support of the *.asc files (simple ascii list of xyz triples arranged in a grid of unknown ratio) Improved Painting tools Texture Parametrization Tool. Tool to inspect and modify texture parametrizations Straightener: a easy to use tool to interactively set reference frames (or in other words to straighten up a randomly oriented mesh). Mesh optimization filters; tools for optimizing a mesh by improving (through edge flipping and relaxation) the aspect-ratio/curvature of the triangles. Geometric erosion filter; a tool for aging a mesh, creating dents and small pits on the most exposed parts of the surface. Interactive selective refinement using RGB-triangulations]. smoothing and unsharp masking filters Photo Texturing Tool. Allows to texture a mesh using one or more images and corresponding calibrated cameras. Ability to edit filter scripts from the filter script dialog (remove, reorder, and change the parameters of filters). Point Picking Tool: a tool for labeling a mesh and saving those labels to an xml file. Morpher Tool: a tool that allows you to morph between any two meshes that have the same number of vertexes. Color Processing Filters: filters for automatically processing per vertex color on meshes (brightenss, contrast, gamma etc). Automatic Rough Alignment of two meshes: a filter to automatically find a rough alignment of two meshes by giving an estimation of their overlapping. Based no the paper [4-points Congruent Sets for Robust Surface Registration Dror Aiger, Niloy J. Mitra, Daniel Cohen-Or ACM SIGGRAPH 2008 ] ReTopology tool: Plugin for building a new mesh starting from an original hi-res model and a simple user defined topology RenderMonkey shader support It is now easier add new rendering modes for the shown meshes. Multipass shaders are supported. Function Filter: a collection of filters used for computing generic functions over the mesh. It's based on the muParser, a fast math parser library. Users can define a function in a simple way and have access to the mesh elements (depending on filter); Partially implemented command line version of MeshLab for batch processing of large number of meshes Surface Sampling and Hausdorff distance measuring plugin. Our beloved metro integrated inside meshlab to compute a metric difference between two meshes editing framework refactoring. Notable bug corrections (since 1.1.1) info picking works with multiple mesh. Bug 1926865: infinite loop when "show quoted box" on a flat mesh Bug 1806887 and 1865951: Wrong support of colored OFF files. improved robustness for non manifold meshes for refining and curvature filters. Bugs 1904897, 1988148 and 1989015: improved support of obj files Improvements Alignment tool much less crashes for 'process' failures... separate buttons for default and specific arc parameters Small filters mesh splitting filters, that allows to split your meshes into layers visualization of texture discontinuities (texture borders) added face index in the info picking tool color conversion (face to vertex and viceversa) texture to vertex color conversion selection based on view angle (useful for range map cleaning) GUI added tooltips to decorations added showing of vertex and face indexes (useful for debugging!) added show face normals added new classes for filters for better structuring the ever growing list of filters added direct save (with automatic overwrite) and "save as" now propose the old file name as default... Added controllable size (alt+wheel) of the rendered points when in point mode. pan (middle mouse drag) is always active in the editing tools. Similarly alt+middle drag is now linked to rotate
