ABSTRACT:
A method and a system for visualizing differences of three-dimensional contour surfaces, in particular of three-dimensional contour surfaces produced by virtually machining a workpiece, are described. The method determines a first and second surface and spatial and/or volume differences between the contours of these surfaces. One of the surfaces together with the determined spatial and/or volume differences between the contours of the surfaces can be graphically rendered, wherein the differences are rendered as an additional attribute of the one surface, for example, in a different color.
