Dynamic Painting of Animated 3D scenes

Painterly rendering is a technique that takes inspiration from traditional painting, such as oil or acrylic. The main idea is to render a 3D scene with 2D strokes in image space. Creating hand made painterly animations is very time-consuming since each frame of the animation is usually obtained by adding some paint strokes over previous frames. With an automated system, a user can not only build his animation faster but can handle the temporal coherence of strokes via a frame-to-frame correspondence. In our system the strokes follow the motion of objects (as in Meier's system [Mei96]) and faithfully represent some of their properties (depth and reflectance), while enabling the user to specify a painting style.
