We present a method for generating line drawings of complex geometries in the style of crosshatched illustrations. Hatching lines are generated by intersecting the geometry with a set of planes. Half-toning on the basis of the generated curves is used to represent a given intensity distribution. Computing a geometric skeleton allows us to determine automatically the orientation of the intersection planes for a wide variety of models. By using predefined line styles different types of illustrations can be generated. Applications of the method are discussed, examples are given.
