Mesh Toolbox is a set of software libraries and executables for manipulating triangular surface meshes originally developed by Andrew Edie Johnson while a Ph.D student in the Robotics Institute at Carnegie Mellon University. Owen Carmicael and Daniel Huber have modified and added to the toolbox and currently maintain the software.

The Mesh Toolbox was written in the context of 3-D computer vision. it contains functions for smoothing, registering, integrating, recognizing and displaying surface meshes. This documentation describes the functionality available in the Mesh Toolbox. For a more in depth look at the algorithms used in Mesh Toolbox, various papers, talks and posters can be consulted.

The Mesh Toolbox was written in C++ and runs on Linux (Red Hat 6.2 or greater), SGI IRIX (5.3 or greater), and Windows (NT 4.0, 98, 2000). Much of the functionality requires the Open Inventor 2.1 toolkit, which is freely available for SGI and Linux platforms but must be purchased for Windows platforms. Furthermore, all surface meshes are represented as VRML version 1.0 indexed face sets.

The original Mesh Toolbox was written by Andrew Johnson and has since been extended by Daniel Huber, Owen Carmichael, Ryan Boller, Vince Broz, and Nicolas Vandapel.
