Geometric Modeling, Simulation and Interaction
Objectives / Challenges
The main objective is to improve the quality in terms of efficiency and robustness of geometric modeling and simulation operations. To achieve this goal, we operate our topological models based on combinatorial maps that facilitate the operations of geometric modeling design through their generic in terms of size and type of cell, and thanks also to the separation of the topology and the embedding of objects which is the basic concept.

Results
- Adaptative and multiresolution volumic model (thèse Untereiner 2013 [8-Unte13]) :
A strong trend in geometric modeling is to use multiresolution to represent objects at different scales. We proposed a model quite original, combinatorial maps multiresolution model based on combinatorial maps. This work was extended with the thesis of Lionel Untereiner [8-UNTE13] in any dimension of meshes. We defined topological and geometric operators to first work on dimension 3 tetrahedral and hexahedral meshes, and more generally on arbitrary topologies with a multi-scale approach [3-UCB12, 2-UCB13].
If multiresolution representations are studied for long time for surfaces, multiresolution models supporting volumetric representations or greater dimension are very rare and limited to very specific applications. The development of generic models with multiresolution simplification operators, subdivision and refinement both topological and geometrical is a major issue in geometric modeling. This work was implemented in the modeling platform CGoGN [4-KUJT13]. An implicit representation, more compact, also has been proposed [2-UKCB15].
