Since the 60s, the Bézier and B-spline representations of polynomials have become an important tool for constructing and editing curves and surfaces in computer-aided industrial applications.  These representations are intuitive, have geometric meaning, and allow for numerically robust algorithms.

In this lecture, we introduce the basics of Bézier and B-spline techniques.  In particular, we focus on algorithms for constructing curves and surfaces and impart an elementary understanding of various related geometric concepts.  For the most part, the lecture orients itself around the book "Bézier and B-Spline Techniques" listed below in the literature.

This lecture is part of the Bachelor's degree program with 4+2 SWS as well as a part of the Master's degree program in which the lab is not required.
