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.
More advanced languages allow decision-making, event handling, and parallel and sequential actions. The Face Modeling Language (FML) is an XML-based language for describing face animation. [5] FML supports MPEG-4 Face Animation Parameters (FAPS), decision-making and dynamic event handling, and typical programming constructs such as loops.
A facial expression database is a collection of images or video clips with facial expressions of a range of emotions.Well-annotated (emotion-tagged) media content of facial behavior is essential for training, testing, and validation of algorithms for the development of expression recognition systems.
This is a list of emoticons or textual portrayals of a writer's moods or facial expressions in the form of icons. Originally, these icons consisted of ASCII art, and later, Shift JIS art and Unicode art. In recent times, graphical icons, both static and animated, have joined the traditional text-based emoticons; these are commonly known as ...
iClone, a 3D real-time animation studio to create animation movies uses Lua in the controls of its new physics simulation. The drawing editor Ipe (mainly used for producing figures with LaTeX labeling) uses Lua for its functionality and script extensions. Leadwerks Game Engine uses Lua for user scripts. [13]

Dozens of similar controllers are used to animate the rest of the face. An arbitrary object deformed by morphing between defined vertex positions. Morph target animation, per-vertex animation, shape interpolation, shape keys, or blend shapes [1] is a method of 3D computer animation used together with techniques such as skeletal animation.
