CIS 462/562: Computer Animation
Some previous exposure to major concepts in linear algebra (i.e. vector matrix math), curves and surfaces, dynamical systems (e.g. 2nd order mass-spring-damper systems) and 3D computer graphics has been assumed in the preparation of the course materials.
Computer Animation: Algorithms and Techniques, Second Edition, Rick Parent, Morgan Kaufman, 2007.
Essential Mathematics for Games and Interactive Applications, James M. Van Verth and Lars M. Bishop , Morgan Kaufmann, 2004.
∑ This course will cover core subject matter common to the fields of robotics, character animation and embodied intelligent agents.†
∑ The intent of the course is to provide the student with a solid technical foundation for developing, animating and controlling articulated systems used in interactive computer games, virtual reality simulations and high-end animation applications.
∑ The course balances theory with practice by ďlooking under the hoodĒ of current games, animation systems and authoring tools and exams the technologies and techniques used from both a computer science and engineering perspective.†
The course will consist mainly of lectures, homework exercises and four programming assignments.†† A mid-term and final exam also will be given.† Grading will be based as follows: approximately 30% on the homework/programming assignments, 35% on the midterm and 35% on the final exam.
