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.
