In computer graphics we look at the form and structure of complex objects in 2D, 3D, nD image and at their modeling, animation and visualization. We rely for that on several topics of research in discrete geometry, topology-based modeling, visualization and lighting simulation and using formal methods in computer graphics.

An important focus of our research is in models conception (discrete, topological, hierarchical) and in modeling tools we use to analyze images, model building, geological layers, or biological structures or to simulate the waves spreading in order to obtain realistic images or determine a reception quality in mobile telephony. We study topological models in a formal order to achieve generic models.

The main field of research in the Computer Graphics team is the modeling, the handling and the rendering of structured objects. The project is characterized by four fundamental themes enabling to achieve this purpose, they are federated in experimentation domains.

Four fundamental Themes

Topology-based geometrical modeling:

for handling structured objects.

---

Using formal methods in computer graphics:

for specifying and validating the geometric operations applied on these structures, and proposing a framework for geometrical computations.

---

Discrete geometrical modeling:

for mainly processing digital images (particular class of geometrical embedding) and studying relations with the euclidean embedding.

---

Visualization and lighting simulation:

for displaying visually realistic representations of these objects.

Experimentation Domains
