METHOD FOR GENERATING A GEOMETRIC OFFSET FORM OF AN OBJECT

摘要

The invention relates to a method for generating a digital geometric offset shape of an object based on a shape of the object according to an offset transformation, the method comprising the following steps: generating a digital geometric shape for describing the shape of the object, the digital geometric shape comprising a plurality of basic figures, as in STL or NURBs; generating a digital geometric offset shape based on the digital geometric shape, characterized in that the method further comprises the following steps; determining an offset vector for each basic figure of the digital geometric shape, the offset vector being a function of the orientation of the respective basic figure in the digital geometric shape; generating a temporary digital geometric offset shape based on the digital geometric shape, the temporary digital geometric shape comprising a plurality of respective basic figures which correspond to the respective basic figures of the digital geometric shape, while each basic figure of the temporary digital geometric offset shape is displaced relative to the corresponding basic figure of the digital geometric shape according to the associated offset vector; generating a digital geometric offset shape based on the temporary digital geometric offset shape, the digital geometric offset shape comprising a plurality of basic figures. The invention further relates to a software program for carrying out the method according to the invention.
