Research Assistant

February 1995 - July 1998

Institute of Mathematics, Chinese Academy of Sciences

�        Thesis: Camera Planning in Automatic Generation of Computer Animation

�      Designed a software layer that can automatically plan cameras movements including starting positions and moving directions in Computer Animation Auto-Generation.

�      This work contributed to Chapter 8: Camera Planning, in Automatic Generation of Computer Animation: Using AI for Movie Animation by Ruqian Lu and Songmao Zhang, P255-283, published by Springer-Verlag, 2002.

�        Automatic Generation of Multimedia ICAI Systems

�      This project was to provide an interactive software environment that can generate Intelligent Computer-Aided Instruction (ICAI) systems automatically. I developed the user interface for the system.

�        Automatic Generation of Computer Animation

�      We developed a software system that automatically generated children's cartoons from a story written by Chinese natural language. I designed a software layer that can automatically plan cameras movements including starting positions and moving directions. I also designed a collision detection algorithm for scene layouts. Our ultimate goal was to automate the animation process and reduce production cost.
