Fabricating fabric

摘要

Films like "Captain America", "Iron Legacy" and "The Curious Case of Benjamin Button" have shown that it is pos'sible to use computer-generated imagery (cgi) to make actors look younger, older or wim-pier than they actually are, in a surprisingly realistic manner. At least, it is possible if those altered actors are kept at a suitable distance from the viewer. The difficulty of recreating the textures of both skin and fabric means the effect is less convincing when seen close up.
