MatGeom is a library for geometry processing / geometric computing with Matlab. It contains several hundreds of functions for the creation, the manipulation and the display of 2D and 3D geometries such as point sets, lines, polygons, 3D meshes, ellipses...
Installation
You can follow one of these procedures (from the simplest one to the most technical):
- From Matlab's "Add-Ons" menu, choose "GetAdd-Ons....", and look for MatGeom. Then simply install or update the toolbox.
- Download the file self-installable "matGeom-1.2.8.mltbx" from the release, and run it from Matlab.
- Download one of the "matGeom-1.2.8.zip" or "matGeom-full-1.2.8.zip" file (that also contains demo scripts and unit test). Uncompress in the directory of your choice. Then, open Matlab, set the path to the directory containing the script "setupMatGeom", and run the script. This should install the main files of the library.
New features in 1.2.8
The 1.2.8 feature is mostly a consolidation and documentation release.
