A method for marking of a polygon - based binary data set of a three-dimensional model

摘要

A process is described, for marking a polygon - based binary data set of a three-dimensional model by means of targeted embedding of an item of information to the binary data set, of the model by means of a plurality of crosslinked surface elements, which in each case by surfaces of the corner points are defined, describes, by changing the position of at least some areas of the corner points. Dollars a the invention is distinguished in that through the change in position of individual surfaces of the corner points, a change in the surfaces normal distribution is brought about, dollars a that a plurality of groups of individual surface normals to so-called embedding region which is - primitive, each of which is provided as am embedding region which is - primitive and is referred to by means of a central normal, the so-called am - center and a radius is defined, wherein in each case those bins at least one surface normal of a surface element of the model is associated with, the angular difference to all of the am - centers is minimal or within a range around the central normal, which by means of a certain radius r around the central normal is defined, and dollars a that to those bins, the at least a surface normal of the model are associated with a mean value of all of the surface normal is formed, which is displaced to the embedding of the information.
