Meshlab

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.

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
  • export:PLY, STL, OFF, OBJ, 3DS, COLLADA, VRML, DXF
  • 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.
• 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
• Remeshing filters:
  • High quality edge collapse simplification (even with texture coords preservation)
  • Surface reconstruction from points (a ball pivoting variant)
  • Subdivision surfaces (loop and butterfly)
  • Feature preserving smoothing and fairing filters
• 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
  • Smoothing
• 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
• 3D Scanning tools
  • 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.
• OpenGL Shader based rendering (write your own shader!) compatible with Typhoon Lab's Shader Designer
• Large rendering (up to 16k x 16k) for high quality printing
• The history of the all performed cleaning/editing actions can be re-played on different meshes or saved and for archival purposes.
• Extendible plugins based architecture, writing new mesh processing functions, colorization filters and support for different file formats is quite easy!
