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 ·
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 using a
limited 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. The broader goal of this project was to apply Artificial
Intelligence techniques to automate the animation process and reduce the
production cost. |
