Medial Object Technology

MAT and MO

The Medial Axis Transformation (MAT) was the subject of intensive research at Queen’s University Belfast in the 1980’s and was then developed by International TechneGroup, Ltd. from 2004 onwards in the form of Medial Object (MO) computation. In recent years the Medial Object has become a key geometric reasoning technology in several EU and TSB supported projects, including VIVACE, CRESCENDO, SILOET, ANSD, SimOD and GHandI. Applications of ITI’s MO have also been explored in several academic research projects. We are aware that there are also several other groups working on MAT methods and applications.

Invitation to CAE Geometry Workshop

14-15 September 2017, Cambridge, England

The aim of the CAE Geometry workshop is to bring together individuals and groups who are active or interested in CAE geometry and meshing problems. To encourage a full exchange of ideas, this is an informal event with no published proceedings, attendees are able to present last minute results. . Attendees are limited to 50, to encourage discussion.

For more information on the upcoming workshop, or for expressions of interest in attending and/or presenting please visit the invitation page: http://info.iti-global.com/cae-geometry-workshop  

To access previous papers presented at the workshop in Cambridge, England, 9-10 October 2014, on the Medial Object and the Medial Axis Transformation (MAT), see below.

2014 Workshop Papers

Most papers are provided below via the links in the titles. Those of Amenta and Ali were, at the time of the workshop, material under preparation for journal publication so are not provided. The Woodhouse talk was an informal, after dinner entertainment talk and is also not available.
