Abstract

In the main section, we introduce new tools for modeling three-dimensionnal objects for computer graphics. They allow interactive modeling of smooth shapes such as organic-looking shapes (animals, human bodies) and help animating and texturing them. A complex object is created by applying a succession of fusion and flexion deformations to a simple object. The fusion tool allows deformation of the shape of the object by merging it with a simple 3D-shape (sphere, ellipsoid,...); the object is deformed so that it embeds the simple shape. The twist tool allows creation of articulations which can be used to animate the deformable object.

In a second section, we introduce a non-photorealistic rendering algorithm. It produces images having the appearance of a traditional cartoon from a 3D description of the scene (a static or an animated scene). The 3D scene is rendered with techniques allowing to outline the profiles and edges of objects, to color uniformly the patches, and to render shadows (backface-shadows and projected-shadows) due to light sources.
