| Aims |
The aim of this lecture is to introduce students to the principles and practice of computational geometry. Both theoretical issues and industrial applications will be presented in order to be able to solve some new problems arising a several fields : robotics, pattern recognition, geography, mechanical manufacturing...

| Content |
Computational Geometry is a relatively new field concerned with designing algorithms and computer programs to perform geometric computations. A need for such computations arises in many fields: computer graphics, robotics, pattern recognition, geography, manufacturing, and so on.
An example is the following problem that arises in medical imaging.
From a CAT or MRI scan, slices through a three-dimensional object are obtained, perhaps a brain tumor. From these slices the object must be "reconstructed." The basic step of this reconstruction is connecting two polygons lying in parallel planes. The connection is effected by finding a collection of triangles that span the two planes, have their corners at vertices of the polygons, and fit together seamlessly to form a closed polyhedron. This basic problem of reconstructing a polyhedron from two parallel polygonal slices has been heavily studied due to its importance, but no completely satisfactory algorithm has been found" (J O'Rourke)
As the objective of this course is to give the student a quick overview in the problems of
computational geometry, modelling and design, the content of the course is as follows:
- Polygons triangulations and partitions,
- Convex hulls in 2D and 3D
- Voronoi diagrams and Delaunay triangulations
- Infography and interactive computer graphics with OpenGL.
- Solid modelling through Bezier and NURBS curves or surfaces.
In addition, a specific variable topic is selected and analyzed.
