FACS coding is also used extensively in computer animation, in particular for computer facial animation, with facial expressions being expressed as vector graphics of AUs. [24] FACS vectors are used as weights for blend shapes corresponding to each AU, with the resulting face mesh then being used to render the finished face.
The body of work around computer facial animation can be divided into two main areas: techniques to generate animation data, and methods to apply such data to a character. Techniques such as motion capture and keyframing belong to the first group, while morph targets animation (more commonly known as blendshape animation) and skeletal animation ...

(There were, however, many more code pages; for a more complete list, see code page). PC keyboards designed for non-English use included other methods of inserting these characters, such as national keyboard layouts , the AltGr key or dead keys , but the Alt key was the only method of inserting some characters, and the only method that was the ...
