geometrical object

One aspect of multi-faceted computer graphics is the creation of geometric objects. Corresponding objects are formed by modeling.

The created models should be easily described, interactively edited and represented by as little data as possible. Moreover, it should be possible to transform the model data with appropriate algorithms.

The modeling of data models is based on lines, curves, surfaces and bodies. Lines and curves can be technically defined by splines and Bézier curves, surfaces by polygons and fractal models and bodies by surface and edge models, by rotation, translation and by composition from partial bodies. In rotation, surfaces are moved around an axis of rotation; in translation, bodies are moved along a straight- line axis or a curve.
