Abstract
The author presents an effective method for modeling realistic
curly hairstyles, taking into account both artificial hairstyling
processes and natural curliness. The result is a detailed geometric
model of hairs that can be rendered and animated via existing methods.
Our technique exploits the analogy between hairs and a vector field; it
interactively and efficiently models global and local hair flows by
superimposing procedurally defined vector field primitives that have
local influence. Usually only a very small number of vector field
primitives are needed to model a complicated hairstyle. An initial model
of hair strands is extracted from the superimposed vector fields by
tracing their field lines. Random natural or artificial curliness can be
added to the initial model through a parametric hair offset function
with a randomized distribution of parameters over the scalp. Techniques
for shearing and clustering are also designed to improve the overall
appearance of the hair model. Our technique has been successfully
applied to generate a variety of realistic hairstyles with different
curliness and length distributions
