0 a two-dimensional figure with many angles and sides. -- polygon
The first layer consists of vertices on the central polygon.
The vertices of a polygon are determined with the evaluation of the combinations.
The rectangle rule will shortly be replaced by the more generic polygon rule, with an additional parameter of number of sides.
Non-simple polygons are easily represented as a set combination of simple polygons.
Generalized polygons are polygons whose edges can be both straight line and arc segments.
Here we have assumed that the obstacles can be generalized polygons and circular shapes with possible holes.
It is enough to work with deformations of standard polygons over an algebraically closed field.
Each new amendment is intersected with existing lines, and new polygons are formed with individual histories.
