In contrast to Cel shading, a painterly rendering images consist of many brush strokes. Therefore, it is impossible to get a painterly rendering image by tuning the shader parameters. It is necessary to use a specialized rendering system for painterly renderings. However, the change in renderer has a big impact on the existing image generation workflow. In this paper, we propose a novel painterly rendering method that generates brush stroke objects as general CG objects for the painterly rendering, enabling a standard photorealistic renderer to generate a painterly rendering image, resulting in a smaller impact to the existing workflow. Additionally, the ability to edit the order of brush stroke is important because a painter draws strokes subjectively, however there is no correct mathematically order. In the proposed method, each brush stroke is converted into an ordinary CG object in the scene, allowing modification of the stroke order directly and easily.
