This image shows the same shoulder region as the previous image but with fur. When the skin isn't elastically adjusted, the hairs are pulled far apart and leave gaps. When the skin is adjusted, the hairs are positioned properly. This image shows various monkeys with fur. The fur model is relatively simple but quite fast.
Parameters give control over density, color, length, curvature, gravity, etc.
A paper describing the fur model will appear in Graphics Interface '97 in May. See also the Fur Page.
