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. In a morph target animation, a "deformed" version of a mesh is stored as a series of vertex positions.
An odd white shape (more often than not, something close to a mushroom) that appears during an exhale represents a sigh of awkward relief or depression. [citation needed] A wavy ghost coming out of the mouth is often a comical representation of depression, mortification, [D 3]: 40 or a comedic and figurative death
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.
Often to speed up the keyframe animation process a control rig is used by the animation. The control rig represents a higher level of abstraction that can act on multiple morph targets coefficients or bones at the same time. For example, a "smile" control can act simultaneously on the mouth shape curving up and the eyes squinting.
In this morph target animation system four "expressions" have been defined as deformations of the geometry of the model. Any combination of these four expressions can be used to animate the mouth shape. Similar controls can be applied to animate an entire human-like model.
Morphing animation between two faces. Morphing is a special effect in motion pictures and animations that changes (or morphs) one image or shape into another through a seamless transition. Traditionally such a depiction would be achieved through dissolving techniques on film. Since the early 1990s, this has been replaced by computer software to ...
Because animating a mouth in synchronization with sound was difficult, Syncro-Vox was soon used as a cheap animation technique. The 1959 cartoon Clutch Cargo produced by Cambria Studios was the first to make use of the Syncro-Vox technique. [ 2 ]
A sample model sheet from the DVD tutorial 'Chaos&Evolutions' In visual arts, a model sheet, also known as a character board, character sheet, character study or simply a study, is a document used to help standardize the appearance, poses, and gestures of a character in arts such as animation, comics, and video games.
