“Chinese Ink Painting with Film Lighting Aesthetics in 3D Computer Graphics ”
My master thesis in Texas A&M University was related with NPR (Non-Photorealistic Render). The motivation behind my research is the unique visual aesthetics in traditional Chinese Ink Painting and my interest in using film lighting principle for enhancing visual story telling. And it's accepted into 2015 SIGGRAPH Poster and Talk.
The goal is to capture the visual aesthetics of Chinese painting in 3D computer graphics and explore the artist possibility of applying film lighting aesthetics in Chinese ink painting for enhancing mood and visual story-telling. I'm using combined solution of developing NPR ink shaders and digital compositing to achieve the final result.
In my research, I wrote a custom ink shader in Renderman Shading language, which is able to mimic ink diffusion and shading techniques in Chinese painting based on the interaction between the model surface and virtual CG lights. This was primary based on paper "Two Methods for Creating Chinese Painting" by Prof. Ergun Akleman, Texas A&M University and " GPU-based Rendering and Animation for Chinese Painting Cartoon " by Manli Yuan, Shanghai Jiao Tong University.
Apart from shader development, I also designed and created custom Nuke Gizmos for compositing. The gizmo reads in different passes at once, including color pass, normal pass, edge pass, ID pass and z_depth pass, and then output the final composited result with custom controls in different parameters.
As a result, a short animation sequence of 3D Chinese ink painting was created based on my workflow, in which two lighting scenario were used to demonstrate my artistic intention and effectiveness of my technical solution. And I'm using 'Jianan Water Country' paintings by Yang Ming-Yi as my primary visual references for concept design.
