Abstract:
Many researches in Non-Photorealistic Rendering (NPR) have been done to investigate a variety of techniques to simulate the styles of hand-drawn artists. Many applications in industrial, architectural, animated film production, technical design, and computer graphics designs have focused on rendering 3D models to depict non-photorealism. Most of them are based on rendering characters and object-based. This paper investigates on non-photorealistic rendering techniques for 3D outdoor scenes. Outdoor scene composed of a large extent of natural phenomena of landscapes, plants, trees, mountains, buildings, and many more. Techniques discussed in this paper include silhouette and cartoonshaded renderings. Silhouette rendering implements Brute Force approach to determine the silhouette edges. Cel-shading algorithm in cartoon rendering renders the objects in the scene by manipulating directional or positional lightings with texture-shaded to give the scene cartoon look.
