geometrical object

One aspect of multifaceted 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, the model data should be able to be transformed with appropriate algorithms.

The modeling of data models is based on lines, curves, surfaces and solids. Lines and curves can technically be 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.
