Abstract	We present a consistent model for artistic medium reproduction in 3D scene renderings and animations. Computer generated stylized animations should reproduce the medium used by the artists while avoiding the artifacts present in hand-drawn animations. In our model, for each scene object, we create a surface grain according to the object geometry and apply it as additional material properties. Our system aims to make these additional material properties remain consistent to the scene / objects animation while avoiding the shower door and popping effects. Moreover, in contrast with existing methods in which coherence is primarily maintained during walkthroughs, our strategy consists in maintaining the grain attachment for any object rotations and non z-axis (i.e. depth) displacements and refining the grain density according to z-axis displacements. Furthermore to prevent this artifact, we propose to select salient additional material properties and reconstruct it for the whole image through a fractal surface reconstruction process. Our model is fully implemented on GPU, results are obtained without any adaptation of the original 3D scene or objects and the rendering process is real-time.
