A Method for Ink-wash Painting Rendering for 3D Scenes

This paper implements a method of rendering 3D scenes containing the elements such as mountains, fog atmosphere and water into ink-wash painting style. In our method, we simulated the texture of Xuan paper and Juan by procedure and extracted feature lines from the mountain models based on curvature. We also added fog atmosphere and water wave effects to make a fuller scene. Besides, we used an empirical ink diffusion model with the background texture representing the absorption capacity of the canvas to simulate the diffusion of ink and achieved the whole process of 3D ink wash rendering. Compared with previous works, we utilized both 3D rendering and 2D image processing knowledge and finally achieved a more complete rendering process automatically transferring the 3D scenes into landscape paintings with better visual effects.
