CS 8113A
Advanced Computer Animation

Spring 1999
College of Computing 102
Class: Tuesday 6:30-9:30

Description
The course will explore current research topics in computer animation such as dynamic simulation of flexible and rigid objects, automatically generated control systems, and evolution of behaviors. This course assumes a knowledge of the basic techniques for computer animation.

Instructor: Jessica Hodgins; jkh@cc.gatech.edu; 214 College of Computing (inside the Animation Lab); 894-9763; Office Hours: Just drop by or send email to schedule an appointment.

General Information

In this course we will explore advanced techniques in computer animation and work together to define new research topics. Each student will lead the discussion for one week during the quarter, define a project, and present it at the end the quarter.

There are no texts for the classes as the readings will all be from papers in the literature.

Possible Topics

The topics for the quarter will be decided during the first class based on student interest. Possible topics include:
Simulating flexible objects
Simulating geological phenomen
Integration techniques
Evolving control systems
Data-driven animation
Interacting characters
Facial animation
Non-photo-realistic rendering of animations
Using animation in interactive spaces
Allowing novices to create animations
Novel commercial uses for animation
2D Animation Techniques
Automatically generating animation based on a soundtrack
More realistic human animation
Programming emotions
Automatic camera/lighting control
