To synthesize images more comprehensibly, image processing techniques can be applied to computer graphics. One example, drawing and emhancing profiles and internal edges, is discussed in this paper. When a shaded image is generated, the range image can be easily obtained as a by-product. Since profiles and edges are discontinuity of the range image, they can be produced by using differential operators. Using this technique, artificial factors such as the strength of edges are separated from geometric or physical factors such as shapes, lighting conditions, etc. Therefore, this method is effective for trial and error to find the best enhancement condition. They can be also applied to draw or to enhance edges of complicated surfaces, or reflected or refracted objects.
