Nowadays, computers play a significant role in art creation as new media and tools. Hence, the relevant techniques on non-photorealistic animation and rendering, artistic simulation, and computational aesthetics are demanding to satisfy the expectation of the digital artists and attract the eyes of the beholders. This thesis presents the main research works finished during the author’s Master studying, which focus on artistic simulation and rendering, as well as two useful novel techniques for ink-wash stylistic rendering and artistic special effects based on fluid simulation. In our first research work, a novel approach to real-time ink-wash stylistic rendering from 3D geometric models is proposed. Firstly, the strokes are classified and extracted from ordinary 3D models by utilizing the existing geometry information, and finally a lifelike painted image can be generated by combining the stroke properties and our ink model. By taking advantage of parallel processing on GPU, the rendering of geometric models with realistic features of Chinese ink painting can be consequently performed on a consumer-level PC in real-time. Moreover, our second work proposes a physically based simulation-rendering framework to generate vivid character-driven special effects that enhance the artistic visual perception of 3D animations. The complex interactions between the liquid simulation based on SPH and deformable character are successfully handled by taking advantage the general-purpose GPU computing. Furthermore, an optimized neighbor search and an improved screen-space particle rendering are also proposed in our framework. As a result, both of the fluid simulation and liquid rendering with realistic illumination can be realized in real-time by using our method.

Stroke-based Real-time Ink Wash Painting Style Rendering for Geometric Models
SIGGRAPH Asia 2012 Technical Briefs, 2012
This paper presents a novel approach for real-time ink wash painting style rendering on geometric models. We first create an ink footprint model in particle form, then extract classified strokes from ordinary 3D models by utilizing the existing geometry information, and finally combine the strokes and the ink to generate an immersive painted image. By taking advantage of parallel processing on GPU, consequently, the rendering of geometric models with realistic features of Chinese ink painting can be performed on a consumer-level PC in real-time.
An Image-based Approach in Animating Painting Procedure of Chinese Ink Painting
Proceedings of Computer Graphics International 2011, 2011
This paper proposes an image-based approach to animate painting procedure of Chinese ink painting at the brush stroke level. Given a painting image, first we obtain its brush strokes by a stroke decomposition method. Then based on our brush stroke model built by vectorization and painting trajectory extraction, animation of its painting procedure can be displayed by our real-time rendering model. As for the applications, our approach could be useful for analysis of Chinese ink painting, as well as for art education.
Flow-Centric Painterly Rendering
2011
We present a painterly rendering technique that emphasizes smooth line flows to describe important shapes in the image, as well as contributing in an essential part to the final stylistic artwork. Our method uses the smoothed edge tangent flow (ETF) [20] for stroke pathing, and provides an artist-friendly way to control the general look and feel of the image using familiar brush stroke properties and colour theme palettes. We achieve a highly stylized expressionistic look that can be applied to still photographs and portraits.
