Absage mündliche Prüfungen

Time:
13.03. bis 20.04.2020

Additional information:

Wegen des Corona-Virus sind alle Prüfungen an der OVGU bis 20.04.2020
ausgesetzt. Dies betrifft auch die noch ausstehende mündlichen Prüfungen
CAGD. Dieser werden auf unbestimmte Zeit verschoben.

Sobald mehr Klarheit herrscht, werden wir neue Termine ausmachen.

Studierende, für die dies ein Härtefall darstellt, melden sich bitte per eMail bei Prof.
Theisel.

Computer Aided Geometric Design
In diverse applications (automotive industry, shipbuilding, design) freely deformable surfaces need to be designed in CAD environments and processed automatically. The underlying mathematical theory and practical aspects are summarized by the term CAGD (Computer-Aided-Geometric-Design). This lecture presents the most important approaches of modeling curves and surfaces. Geometric properties of these techniques will be discussed along with the practical experiences regarding the design of curves and surfaces.
