Abstract

Described is compressing a digital representation of an object, wherein the object representation comprises image information items for the object that each specify a value of a measurand for the object at a defined position of the object. Compressing includes determining the object representation, determining a distance field from the image information items of the object representation that comprises a plurality of data points in a grid, the distance field assigns at least one distance value to each of the data points that in each case indicate the shortest distance of the data point from a closest material boundary of the object, determining a near region around a material boundary of the object, determining a sub-set of data points of the distance field which lie outside the near region, deleting the sub-set of data points, and saving the distance field in the form of a compressed object representation.
