Abstract: We present a new approach to create painterly renderings of an animated 3D scene, allowing a controllable trade- off between scene fidelity and stylistic design. Our approach extends and complements existing systems in order to ensure temporal coherence while maintaining consistent stroke density, and allowing a wide variety of stroke styles. It is based on a new dynamic painting algorithm which selects a suitable set of sample stroke locations based on an object-space hierarchy. We describe also an improved stroke drawing technique which allows a faithful depiction of the scene while letting the user specify his preferred stroke style via a shader. All renderings are interactive and performed on the GPU.

%2 Nous prÃ©sentons une nouvelle approche pour crÃ©er une animation en rendu peinture Ã partir d'une scÃ¨ne 3D animÃ©e. Notre approche Ã©tend et complÃ¨te les mÃ©thodes existantes pour assurer la cohÃ©rence temporelle de l'animation, conserver une densitÃ© constante de coups de pinceau et offrir Ã l'utilisateur un libre choix de style. Pour cela nous prÃ©sentons un algorithme dynamique qui sÃ©lectionne Ã la volÃ©e un ensemble adaptÃ© de coups de pinceau en s'appuyant sur une hiÃ©rarchie de points Ã la surface des objets 3D. Nous proposons de plus une technique de dessin de coups de pinceau permettant une reprÃ©sentation fidÃ¨le de la scÃ¨ne tout en offrant Ã l'utilisateur la possibilitÃ© de spÃ©cifier son style via un shader. Le rendu est interactif et effectuÃ© sur le GPU.
