Description

This unit introduces the fundamentals of digital geometry processing.

Compétences requises

Mathematics: vector calculus, matrix algebra. C++ programming.

Compétences visées

At the end of this teaching unit, a student will know :

- The context of digitizing 3D geometric shapes and the basics of surface representations in the form of 3D point clouds;

- How to put into perspective and compare different shape representations such as 3D point clouds, polygonal meshes, parametric surfaces, implicit surfaces, and voxel sets;

- How to compute differential features (curvatures, Laplacian) on a triangular mesh;

- How to modify a 3D shape represented as a polygonal mesh: smoothing/denoising, simplification, remeshing.

Disciplines

• Informatique

Syllabus

Lectures begin by presenting the acquisition processes (digitization) and the main discrete representations of 3D shapes. It then focuses on polygonal meshes and presents the mathematical and algorithmic tools allowing their analysis and modification. The practical sessions complete and put into practice the concepts seen in class, in particular through the realization of a real software project on this theme.
