WONG, Tien-Tsin (T. T.)

B.Sc., M.Phil., & Ph.D.(Computer Science, CUHK)

Professor
Dept of Computer Science & Engineering
The Chinese University of Hong Kong

He graduated from the Chinese University of Hong Kong in 1992 with a B.Sc. degree in Computer Science. He obtained his M.Phil. and Ph.D. degrees in Computer Science from the same university in 1994 and 1998 respectively. From August 1998 to August 1999, he was a visiting assistant professor in the Computer Science Department of Hong Kong University of Science & Technology. In August 1999, he joined the Computer Science & Engineering Department of the Chinese University of Hong Kong. He is currently a professor. He is a core member of Virtual Reality, Visualization and Imaging Research Centre in the Chinese University of Hong Kong. Recently, he received the IEEE Transactions on Multimedia Prize Paper Award 2005 and the Young Researcher Award 2004.

He is currently the visiting professor in School of Computer Science and Technology at Tianjin University, and the visiting research professor in Biomedical Engineering Department of Shanghai Jiaotong University. In the summer of 2000, he was a visiting researcher in Microsoft Research, Asia. He is the member of ACM, ACM SIGGRAPH, IEEE, and Eurographics Association. He has actively involved (as Program Co-chair, Program Committee and Organizing Committee) in several international conferences, including Eurographics (2007, 2008), Pacific Graphics (2000-2005, 2007), Computer Graphics International (2004, 2006), Medical Imaging and Augmented Reality (2001), International Conference on Image and Graphics (2002), CAD/Graphics (2003, 2005-2007), Chinagraph (2000, 2002, 2004, 2006) and ACM VRCIA (2006). Besides, he is also active in transferring graphics technologies to games industry, including writing articles in books for game developers (Graphics Gems V, Graphics Programming Methods, Shader X³, ShaderX⁴, and ShaderX⁵).

His main research interests include computer graphics, precomputed lighting, image-based rendering, computational manga, GPU programming, medical visualization, multimedia compression, and computer vision. In 2005, he started a project in Computational Manga and presented in SIGGRAPH 2006. In 1997, he proposed one of the earliest representations for image-based relighting, apparent BRDF of pixel. He also proposed a geometry-dependent framework for modeling surface imperfections, such as dust accumulation, in 1995 (reported in Computer Graphics World magazine). Currently, he actively involves in the projects of Rendering-friendly Compression and Real-Time Visualization of Chinese Visible Human (see press clipping), the highest resolution visible human data set.
