Prerequisites:  Numerical Analysis, knowledge about Matlab.

Content of the lecture:

The course gives an introduction to the representation of geometrical objects in computer systems and their manipulation. The representation of curves and surfaces in various graphical systems is based on polynomials, splines and NURBS (non-uniform rational B-splines). The course gives an elementary introduction to the geometric properties of such representations and furnishes some mathematical background for geometrical algorithms such as: subdivision, projection, surface-surface intersection. Numerical techniques for data fitting by curves and surfaces are explained.
