This Computer Animation subject is focused on computer animation, which essentially means “computer algorithms and programming techniques for specifying and generating motion for graphical objects” (R. Parent, Computer Animation, Algorithms and Techniques, 3rd ed, Morgan Kaufmann, 2012, Preface). More specifically, it mainly deals with three-dimensional (3D) computer animation of virtual human characters. However, it introduces the field in general; and the animation techniques we discuss are more generally applicable, for instance to some virtual animals.

Computer Animation is used mainly in entertainment (movies, games, social media), but it also has applications in other areas, suchas biomedicine. We focus on the former applications, as part of Computer Graphics Imagery.

The subject is presented in a very practical way, with theory, seminars, and labs closely intertwined.
