Mots cls : Rendu non photoraliste, rendu procdural, style, dessin Figure 1: Two line drawings generated from a 3D model using our system. 1 Introduction The field of Non Photorealistic Rendering [GG01, SS02, Dur02] has proposed a variety of techniques to create compelling line drawings from 3D models. Unfortunately, these methods are generally hard coded in monolithic software and lack a flexible and formal specification framework. In contrast, the shading languages available in photorealistic renderers ....
....Developers can also implement new predicates based on more complex functions of the scene. 4.2 Chaining Chaining operators are responsible for creating connected lists of ViewEdges, which we call chains. A chain therefore represents a one dimensional graphical element in image space [Wil97, Dur02] which will be used to control stroke creation. Chaining is responsible for converting from the graph nature of the ViewMap to the one dimensional nature of strokes. However we note that there is not necessarily a simple correspondence between chains and strokes: in particular while chaining is ....

....3D motion with a 2D transformation. An infinite zoom in the texture is made possible by using a paper model based on multifrequency solid turbulence. Our results indicate a dramatic improvement over a static background. 1 Introduction The field of Non Photorealistic Rendering [GG01, SS02, Rey02, Dur02] not only captures the qualities of traditional media, but also permits their animation. Media that were inherently static come to life and can be animated and used for interactive walkthrough. This raises a number of challenges: How should the elements of the picture such as strokes (marks) or ....
....In the first case, the scene appears to be viewed through a shower door, and in the second, the 3D objects seem to be textured with, or carved in, artistic strokes. The problem boils down to the tension caused by the dualism of pictures, both 2D compositions and representations of 3D scenes [Dur02] In previous work, much attention has been paid to strokes and their temporal coherence, but the temporal behavior of the background canvas or paper has been mostly ignored. As a result, most NPR animations or walkthroughs seem to be projected on a paper or canvas texture using a slide ....
