Detailed Description

Curve in three-dimensional space.

Curves are members of a family of three-dimensional geometric objects. Curves are used for construction of surfaces and auxiliary elements of geometric model. In geometric modeling there are used curves which are easy to control. Control is performed by the data which curves constructed by. Curves are constructed using analytical functions by a set of points on the basis of curves and on the basis of surfaces.
