Construction of sections

The purpose of construction of sections is creation of a file of points with values of semantic characteristics, multiple to a step of isolines construction. This file is the base for tracking isolines. Process of sections construction is spent by a method of interpolation of planned position of the node of section with the semantic characteristic, multiple to a step of construction of isolines. For interpolation the next apices of one triangle from Delone triangulation are taken. Process continues until all edges of a triangulation will not be covered by sections of semantic characteristics.
