Abstract
Blend shapes, also known as morph target animation, are a powerful way of deforming geometry such as human face to create various facial expressions, from happy to sad. In this presentation, after overviewing Autodesk Maya blend shapes, their features and work flow, Professor Xu will demonstrate and discuss how to create a more efficient workflow by combining blend shapes with Maya’s Set Driven Key features, and how to create a more complex facial animation with advanced blend shape techniques and features. Concepts and techniques such as blend shape deformer, Blend Shape node, Tweak node, Set Driven Key, morph target animation, vertex position, and more will be introduced and demonstrated. Finally, Professor Xu will discuss the advantages and disadvantages of using morph target animation over skeletal animation in 3D facial animation.
