Handbook of Human Motion pp Cite as. Blendshapes are a standard approach for making expressive facial animations in the digital production industry. The blendshape model is represented as a linear weighted sum of the target faces, which exemplify user-defined facial expressions or approximate facial muscle actions. Blendshapes are therefore quite popular because of their simplicity, expressiveness, and interpretability.

Specifies the name of the blend shape deformer the blendShape node. You should rename this node so that it indicates the role of the blend shape deformation for example, lipSync. You can create multiple blend shape deformers on an object or a group of objects. See Create blend shape deformers for more information.
The face is one of the most complex areas of the human body, and understanding the motion of the face is even more complex. Being able to split facial motion into key shapes to be used together to form expressions not only simplifies the face but allows you to re-create these shapes in CG, and animate complex expressions. This workshop assumes you have no prior knowledge of blendshapes, and takes you through the full facial process using Autodesk Maya.
Shape authoring provides you with different tools to accomplish your shape deformation tasks. Blend shape deformers let you change the shape of an object into the shapes of target shapes, such as for creating facial animation on a character. You can also use blend shapes to correct deformations on a skinned character's body, for example.
