SUMMARY:Curly-Cue: Geometric Methods for Highly Coiled Hair
DESCRIPTION:Haomiao Wu and Alvin Shi (Yale University), A.M. Darke (Univer
 sity of California Santa Cruz), and Theodore Kim (Yale University)\n\nWe p
 resent geometric methods for generating shapes that are characteristic of 
 highly coiled hair. Different features become visually relevant when hairs
  are well-approximated by high-frequency helices instead of a low-frequenc
 y curves, so we present algorithms for three such phenomena. First, a Four
 ier-based method for phase locking, the process by which disparate helices
  near the scalp coalesce into a single curl. Second, a method for period s
 kipping which models individual helices deviating from the coalesced curl.
  Third, a non-linear optimization that directly generates the shapes of sw
 itchbacks, a.k.a. helical perversions, which heretofore could only be prod
 uced through direct physical simulation. By applying all three methods in 
 tandem, we show that we can achieve richly detailed depictions of highly c
 oiled hair.\n\nRegistration Category: Full Access, Full Access Supporter\n
