STL openSource et autres


MeshLab is an open source Windows and Linux application for visualizing, processing and converting three dimensional meshes to or from the STL file format.

MeshLab Homepage

MeshLab, started in late 2005, is a free and open-source general-purpose mesh processing software program; the system is aimed to help the processing of the typical not-so-small unstructured models that arise in the pipeline of processing of the data coming from 3D scanning. MeshLab is oriented to the management and processing of unstructured large meshes and provides a set of tools for editing, cleaning, healing, inspecting, rendering and converting these kinds of meshes.

The automatic mesh cleaning filters includes removal of duplicated, unreferenced vertices, non manifold edges and null faces. Remeshing tools support high quality simplification based on quadric error measure, various kinds of subdivision surfaces and two surface reconstruction algorithms from point clouds based on the ball pivoting technique and on the Poisson surface reconstruction approach. For the removal of noise, usually present in acquired surfaces, MeshLab supports various kinds of smoothing filters and tools for curvature analysis and visualization.

MeshLab also includes an interactive direct paint-on-mesh system that allows to interactively change the color of a mesh, to define selections and to directly smooth out noise and small features.

Version 1.1.0 also includes a tool for the registration of multiple range maps based on the Iterative Closest Point algorithm.

MeshLab is available for most platforms, including Windows, Linux and Mac OS X intel only. The system support input/output in the following formats: PLY, STL, OFF, OBJ, 3DS and COLLADA.

————Art of Illusion

Art of Illusion is a free, open source 3D modelling and rendering studio. It is written entirely in Java, and should be usable on any Java Virtual Machine which is compatible with J2SE 1.4 or later.

File Handling

Mac OS X

Art of Illusion requires Mac OS X 10.4 or later with all software updates installed.

  1. Download the Art of Illusion installer.
  2. Double-click it to mount the disk image, then copy the « Art of Illusion » folder to your Applications folder.
  3. (optional) Download the Java Media Framework. Select the « Cross-platform Java » version. After you download it, find the file jmf.jar and move it to /Library/Java/Extensions. The rest of the downloaded files are not needed, and can be deleted. (This step is not required, and most of Art of Illusion will work normally without JMF. You will not be able to save animations in Quicktime format, however, if it is not installed.)
  4. To launch the program, double-click the Art of Illusion icon.


RepRap is an OpenSource project that uses STL file input and generates solid objects as output.

On peut utiliser des parties de ce projet pour la gestion et modif des STL.

There are many other file formats capable of encoding triangles available, such as VRML, DXF, but they have the disadvantage that it’s possible to put things other than triangles into it, and thus produce something ambiguous or unusable.
