%X An algorithm was introduced to generate line-style drawings of 3D triangle meshes.In the preprocessing stage,mean curvatures of vertices were estimated.At runtime,through interaction with user,concave regions under consideration were detected and skeletons of them were extracted using a heuristic searching method.Combining skeletons with contours and adding illumination effects shapes can be illustrated with a hand-made appearance.Experimental results validate the algorithm.
