Historic

The research group "Informatique Géométrique et Graphique" (IGG) - meaning Geometry and Graphics - is structured around two main topics :

• Modeling, construction and proofs in geometry.
• Visualization, interaction and simulation.

In a more transversal fashion, the research efforts also consider more general problems such as the definition and implementation of a modeling platform or in the following application fields: medical imaging, geological modeling, physical phenomena's simulation and Computer Aided Design (CAD).

Modeling, construction and geometrical proofs

The underlying central problem of this theme is geometric modeling which is approached from different point of views. This theme therefore splits into three complementary operations :

• Geometrical and topological modeling,
• Geometrical constraints solving,
• Specifications and proofs in geometry.

Visualization, interaction and simulation

This theme is developed together with the program called RéVA. It splits into two complementary operations :

• Simulation, visualization and rendering,
• 3D Interaction.
