Detailed Description

Topological object in three-dimensional space.

A parent class of topological objects in three-dimensional space.
Geometric properties are called topological if they are not depend on the quantitative characteristics (lengths and angles), but reflect continuous connection between an object and its environment.
topological objects also describe the object geometric properties which depend on quantitative characteristics and geometric properties, which reflect continuous connection between an object and neighboring elements. topological objects are constructed on the base of points, curves and surfaces by adding to their data, properties and methods a new data, properties and methods.

The documentation for this class was generated from the following file:
