Release Notes 1.1.0

From Meshlab

Version 1.1.0 is a big milestone with many important new features added. The most notable improvement relies in a major rewriting the way of managing parameters, the new possibility of managing more than a single mesh on different layers, and the 3D scanning oriented new big features (alignment and merging). The 1.1.0 version has been released on 29/01/2008.

New features

• Measuring tool. You can take linear measures between points of the displayed meshes
• Slicing tool. A new tool that allows to export planar sections of a mesh in SVG format
• 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 with 3D objects with just MeshLab and LaTeX.
• Layers Multiple meshes can be loaded in the same space and processed separately
• Alignment ICP based range map alignment tool, for putting meshes into the same reference space.
• Merging of multiple meshes the Poisson surface reconstruction source code (kindly provided by by Michael Kazhdan and Matthew Bolitho) have been included in.
• Ambient Occlusion. An ambient occlusion field can be computed and stored per vertex.
• Filter Help All (most of) the filters have a displayable detailed explanation of the meaning of their parameters.
• A set of new filters have been added:
  • border removal
  • coloring with geodesic distance from borders
  • random displacement of vertices
  • new basic way of instancing new objects directly inside MeshLab (menu file->new). The number of possible new objects will increase in the next releases.
  • deleting of face and vertices toghether
  • coloring of faces according to various measure of triangle shape quality
  • info picking tool to know indexes of the vertices of specific triangles.
  • selection of self-intersecting faces

Notable Bug Corrections

• Corrected bug in quadric simplification mac (now it has the same quality of the win/linux version)
• More parameters on the two-step smoothing (now works on selections too)
• More coherent switching between editing modes when using interactive tools
• No more hanging when starting the texture-simplifying filter on a mesh without a texture
• Improved loading of Collada files. Now meshes with polygonal faces of non trivial shape are robustly triangulated
• Clustering now preserves color.
• Improved robustness of Ball pivoting algorithm
• the dialog asking if you really want to close an unsaved object has a meaningful behavior
• When saving OBJ files the mtl files are saved in the correct place

Known Bugs

We know about that and we are working on them (see Release Notes 1.1.1).

• the Slicing tool can hangs when exiting and reentering from the tool.
• jpg support on mac sometime fails
• global alignment sometime fails
• some 3ds files can crash (patched in 1.1.1)
• opening meshes with different attributes in different layers can crash (patched in 1.1.1)
• Computing self intersection after some editing can crash (patched in 1.1.1)
• u3d under windows does not work well :). patched in 1.1.1. For 1.1.0 users add the 4 dlls contained in this zipin the u3d plugins directory. The u3d plugin dir should be somewhere like

C:\Program Files\VCG\MeshLab\plugins\U3D_W32\plugins

• u3d conversion of textures currently works only for tga files. (patched in 1.1.1)
