Real-time Rendering of Wet Fur

Fur is present in most mammals which are common characters in both movies and video-games, and it is important to model and render fur both realistically and fast. In computer graphics, there are mainly two approaches to fur rendering. Using primitives such as lines or curves, and using textures containing sampled fur geometry. The former case is oriented towards realism and the latter case focusing on real-time rendering performance. However, the existing research focused on real-time rendering leaves out important factors such as the clumping effects visible when fur becomes wet or dries up. In this paper we describe a method to simulate effects visible in water-fur interaction such as the change in color and shape of the fur (see Fig. 1 and Fig. 2).
