FIELD: engineering of image processing devices. ^ SUBSTANCE: information is produced about position of surface of input three-dimensional object, this surface is simplified as a set of base polygons, information is produced about position of simplified surface of input three-dimensional object and information map of surface is generated on basis of information about position of surface of input three-dimensional object prior to simplification and information about position of simplified surface of input three-dimensional object; surface of each basic polygon is split in information map of surface on multiple area and excitations function is produced for each area; error is determined between object on basis of excitations function and by given three-dimensional object; it is determined whether error is less than threshold value; if error is less than threshold value, match is set between coefficients of excitation functions for basic polygons and information about basic polygons, while information map of surface is information about surface of input three-dimensional object, and if error is not less than threshold value, than surface of object, represented by information map, is split finer in comparison to previous splitting. ^ EFFECT: possible processing of three-dimensional object with highly efficient compression. ^ 2 cl, 13 dwg
