FIELD: physics.
SUBSTANCE: method includes creating a boundary of a graphic object; applying the boundary of the graphic object at predetermined intervals of the crossing elements crossing the boundary of the graphic object at the intersection points at the same angle of intersection; measuring a set of angles between the crossing elements; in response to the fact that, at least, one angle between two particular crossing elements exceeds a predetermined threshold, dividing the boundary into fragments of the boundary; creating baselines for each created fragment of the boundary; projecting heights from each of the many fragments of the boundary to their respective baselines with a predetermined height increment; defining the heights; saving data for drawing a boundary fragment as a collection of: sets of coordinates of baselines, a height step, and a sequence of heights in connection with the corresponding baseline.
EFFECT: saving the boundaries of graphic objects in the form of height maps for graphic objects with nonmonotonic boundaries.
