Pole  : Geometry and Modeling

Beginning date Dec 05, 2013
Teams Presentation News

The "Geometry and Modeling" pole develops its research activities by considering geometry as a core. Whether for analyzing or modeling, the common thread of its teams is to design algorithms that are efficient and robust, in order to produce and manage high quality objects and scenes. The input geometric elements may correspond to point clouds, meshes or images.

Expertise of the pole

The main skills of the pole relate to computational geometry, discrete geometry, geometric and topological modeling. Using these skills, the members have particular knowledge in 3D reconstruction and interactive creation (while ensuring dynamicity and evolutivity, with quality control of the result), procedural modeling (urban or natural complex scenes, ecosystems), geometry processing of meshes and discrete shapes (feature extraction, indexing and retrieval, compression, watermarking, segmentation, visualization), topological modeling. The algorithmic approach advocated by the pole implies a particular attention to the processing and handling of large objects and scenes.
