A volumetric model of the object is initialised with a material distribution according to the design data, the volumetric model having a plurality of volume elements.

Based on this, the target property of this volume element is modified in such a way that it approaches the target property if it is supported and/or moves away from the optimisation target if it is not supported.

Abstract: In a method for recording and reproducing pressure wave signals, a wave pressure recording and an analog digital converter are to be linked. Higher dynamics are to be effected at identical bit depths and lower bit depths are to be required for identical dynamics. All information provided by the pressure wave signal is calculated and stored on the basis of detected and directly quantified wave pressure differences of the pressure wave signal. In addition, coefficients can be stored and, if necessary, retransformed into absolute wave pressures. In this way, the pressure wave signal can be reproduced.
