Contracts and Grants with Industry

Axiatex 11/2009-04/2011

Participants : Adrien Bernhardt, Marie-Paule Cani, Jean-Claude Léon.

We extended the Aestem Studio software to cover the needs of the company Axiatec, which sells 3D printers in France. The goal is to provide 3D modeling system based on a very intuitive sketch-based technique, in order to enable the general public to model 3D shapes. Our extensions included the introduction of texturing methods and of interactive editing mechanisms, in addition to an eraser tool enabling to carve the surface through sketching.

EADS - Idealization of components for structural mechanics (05/2011 - 04/2014)

Participants : Jean-Claude Léon, Stefanie Hahmann.

Cifre PhD in partnership with EADS IW to generate the shape of mechanical components through dimensional reduction operations as needed for mechanical simulations, e.g. transformations from volume bodies to shells or plates forming surface models, usually non-manifold ones. The topic addressed covers also the shape detail removal process that takes place during the successive phases where subsets of the initial shape are idealized. Mechanical criteria are taken into account that interact with the dimensional reductions and the detail removal processes. The goal is to define the transformation operators such that a large range of mechanical components can be processed as automatically and robustly as possible. Some results from the homology computation topic may be used in the present context. An ongoing publication should address the description of the various stages of a component shape transformation in the context of assemblies.
