Virtual actor
（重定向自Synthetic actor）
A virtual human or digital clone is the creation or re-creation of a human being in image and voice using computer-generated imagery and sound, that is often indistinguishable from the real actor. This idea was first portrayed in the 1981 film Looker, wherein models had their bodies scanned digitally to create 3D computer generated images of the models, and then animating said images for use in TV commercials. Two 1992 books used this concept: "Fools" by Pat Cadigan, and Et Tu, Babe by Mark Leyner.
