Method for Producing Three-Dimensionally Structured Surfaces

A method for producing three-dimensionally structured surfaces of objects, an object surface being generated as a reproduction of a three-dimensionally structured original surface with an aid of a machining tool, which comprises the steps of:

• a) determining a topology of the original surface with an aid of a three-dimensional scanning method, and topological data thus determined and generally containing height values and depth values belonging to each surface element of a raster spanning the original surface, are stored in a first data record, the surface element or a raster element being assigned a measured depth value;
• b) subjecting the first data record to an assessment of the depth values with regard to their influence on reflection properties of surface elements;
• c) assigning a reflection value as a parameter to each of the surface elements, depending on an assessment, and storing the refection value in a second data record;
• d) revising the depth values of the first data record in dependence on reflection values of the second data record resulting in revised depth values;
• and
• e) storing the revised depth values of the first data record as topological data in a third data record and are used for electronically controlling the machining tool for machining the three-dimensionally structured object surface.
