"Geometric Modeling and Computer Graphics"

A system for modeling a wonderful curve. The Dan System
performs the following actions:
to establish a curve in the dialogue regime;
automation and manual vibration of parameters that are necessary for
to build curves;
animation change of curve when automated parameters change;
the establishment of touch and normal at the curve point;
Asymptoms, if they exist;
calculation of the radius of the curve, area, point of periphery, area of kileć (as
The lengths of the hole
performing euklid conversions with the curve;
the curve is visualized with the grid and the axis in the Decartov system of coordinates
