<p>The invention relates to a method for removing material from a three-dimensional surface ( 1 ) of any shape in a single or multilayered manner by means of a material removing agent ( 9 ), such as a laser, that acts in points on the a surface and where a surface structure ( 2 ) is applied to the three-dimensional surface ( 1 ); wherein the inventive methods can be carried out in such a way that the surface ( 1 ) is described by a mathematical function and approximated by a polygon whereby each polygon of the polygon network is assigned to a work area for the laser. Raster images are associated with each of the polygons, which determine the depth values for the surface structure. The polygons ( 3 ) are removed line by line. When the depth values of the surface structure differ by a large margin, the material removal takes place in several layers ( 7 ) of polygon networks.</p> |
