Fur is a synonym for hair, used more in reference to non-human animals, usually mammals; particularly those with extensives body hair coverage. The term is sometimes used to refer to the body hair of an animal as a complete coat, also known as the “pelage”. Fur is also used to refer to animal pelts which have been processed into leather with the hair still attached. The words fur or furry are also used, more casually, to refer to hair-like growths or formations; particularly when the subject being referred to exhibits a dense coat of fine, soft “hairs”. Animal fur, if layered, rather than grown as a single coat, may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Mammals with reduced amounts of fur are often called “naked”, as in The Naked Ape, naked mole rat, and naked dogs. An animal with commercially valuable fur is known within the fur industry as a furbearer. The use of fur as clothing and/or decoration is considered controversial by some people: most animal rights advocates object to the trapping and killing of wildlife, and to the confinement and killing of animals on fur farms. Fur has been a big challenge for 3D computer graphics artists due to its geometrical complexity and self-shadowing effects. The first movie which made extensive use of CGI-fur was Pixar’s Monsters, Inc. from 2001.
