Tomoyuki Nishita started research on Computer Graphics (CG) in 1972, working on hidden surface removal, occlusion and shadow calculations.
He developed a method for rendering scenes taking into account different types of illumination and obtained an award from the Information Processing Society of Japan in 1987.
In this research, specifically, he developed a method for making realistic images taking into account interreflections between objects and presented it at Siggraph, the maximum authority in Computer Graphics [See reference 1]. That technique became known as "radiosity" and placed him as one of the pioneers in this field.
He then developed it further and proposed several shading models (Eurographics 1995, Best Paper award, Institute of Image Electronics Engineers of Japan 1996, Paper Award).
In recent years, he has researched the realistic visualization of clouds, smoke, atmosphere, water, snow considering different optical effects like multiple scattering.
Among these methods, the use of cell automata for simulating cloud dynamics in real time stands out. He also obtained the Nicograph Best Paper Award in 1999 for his research in 2D image morphing.
During this time, he has written twelve SIGGRAPH and twelve EUROGRAPHICS papers, and received Steven A. Coons award from SIGGRAPH in 2005.

| Other Activities |
Currently I am affiliated to eight academic associations, serving as committee chairman of the Visual Computing chapter of the Institute of Image Electronics Engineers of Japan and being a committee chair of the Graphics and CAD chapter.
Regarding international publications, I have been editor of IEEE's "Transactions on Visualization and Computer Graphics"('94-'98), and currently I am a member of the editorial board of the following journals in Taiwan: Journal of Information Science and Engineering and The Visual Computer Journal.
Also, I have served as a member of the papers committee in ACM's SIGGRAPH special interest group ('93, '94, '99, '00)and have been in the program committee of more than 30 conferences like Eurographics, CG International and Pacific Graphics.
Regarding my industry-related activities, I was an NTT senior adviser, technical advisors of three companies, and I have served in several posts like: consultant of the CG conference of Hiroshima Prefecture, chairman of Electronics division of Hiroshima's technical Electronics Center.
I also have served as vice president of the Institute of Image Electronics Engineers of Japan.

| Future Plan |
My main research areas are related to the realistic visualization of complex natural sceneries and CG for use in the entertainment industries. Specifically:
- Applying cell automata, chaos and fractal theories for modeling and visualization of natural phenomena.
- Developing a system of distributed virtual reality in cooperation with some of China's CAD/CG state key research labs.
- Development of high-speed rendering methods applicable to games, using the latest hardware.
Regarding education, I have an interest in spreading and promoting Computer Graphics through Internet, being web-based training and distance learning the main focus. In this regard, we were awarded in 2002 for the excellence of our teaching materials, jointly developed with the association for the promotion of the Institute of Image Electronics Engineers of Japan. Specifically, using Java applets we built a system for learners to experiment interactively with different CG techniques.

| Messages to Students |
In this department of Complexity Science and Engineering, we have the objective of creating a new paradigm to tackle onto Complexity using both Science and Technology.
Specifically, we cover the areas of Computer Science, Mathematics and Planetary Science.
We believe that it is necessary to borrow from multiple academic fields to create new comprehensive knowledge. I myself was a student of Electrical Engineering, but after working in the automobile industry and learning about manufacturing, automatic control and noise research, I went back to the University to take charge of matters related to hardware and software. In those days I was always in contact with people outside of my specialty.
It can be said that the ability of mixing knowledge from different fields in the middle of chaos is the specialty of this department.
Because of the above, I am looking forward to students who, mixing science and technology, have the will to become pioneers and establish new research areas.
