Overview

Recent progress in Geometric Modeling has been stimulated by numerous applications in engineering and multimedia. The purpose of the course is to give an introduction to classical and modern mathematical techniques employed in Geometric Modeling and to demonstrate how these techniques are useful for the design and manufacture of engineering objects of high quality, entertainment and multimedia applications. The course will also serve as a starting point for those students who wish to use Geometric Modeling concepts and ideas in their own research. Topics to be covered include shape interpolation and approximation with piecewise polynomial curves and surfaces, mesh processing, and multiresolution modeling.

Course topics:

Mathematical background for geometric modeling
Modeling Techniques:

Splines, curves and surfaces
Bezier splines, B-Splines, NURBS, implicit functions
Variational Modeling

Geometry Processing:

Processing of 3D scanner data
Registration, reconstruction, data fitting

Practical Skills:

Programming assignments & tutorials

Schedule

Software

GeoX is our programing framework for the practical tutorials. The software is open source (GPL2).

Download the sources including an introduction to the GeoX framework.

Expected Work

The course is suitable for MS students. Familiarity with basic computer graphics (or motivation to quickly learn them) is desirable. Assessment will be based on weekly assignments and a written exam at the end of the semester.

Assignments

To be admitted to the exam, you need to have

· Turned in 100% of all homework assignments. Yes, you need to work on all assignments.
