Abstract

A method for producing three-dimensionally structured surfaces of objects, the object surface being created as a reproduction of a three-dimensionally structured original surface with the aid of a machining tool. Accordingly, the topology of the original surface is first determined, a measured depth value being assigned to each surface or grid element, creating a depth map of the original surface. The depth values are evaluated in terms of their influence on the reflective properties of the surface elements and the reflective properties are stored in the form of parameters. The depth values are then modified in accordance with the reflective values and are used as topological data for the electronic control of a machining tool.
