Abstract: A procedure for structuring and storing data representing the form of an object that can be represented by a set of interpolation points, wherein the data representing an object is stored in a hierarchy having at least two levels, wherein a subset of the data representing the object is saved at each level and wherein the data is assigned to the levels by selecting at least two anchor points, whose data is saved in the uppermost hierarchical level, from the set of interpolation points and by consecutively selecting, from the interpolation points remaining in the set, the interpolation point with the largest distance from a line through the interpolation points and anchor points that have already been assigned to levels.
