Darke (University of California Santa Cruz), and Theodore Kim (Yale University)\n\nWe present geometric methods for generating shapes that ar e characteristic of highly coiled hair. Different features become visually relevant when hairs are well-approximated by high-frequency helices inste ad of a low-frequency curves, so we present algorithms for three such phen omena. First, a Fourier-based method for phase locking, the process by whi ch disparate helices near the scalp coalesce into a single curl. Second, a method for period skipping which models individual helices deviating from the coalesced curl. Third, a non-linear optimization that directly genera tes the shapes of switchbacks, a.k.a. helical perversions, which heretofor e could only be produced through direct physical simulation. By applying a ll three methods in tandem, we show that we can achieve richly detailed de pictions of highly coiled hair.\n\nRegistration Category: Full Access, Ful l Access Supporter\n\nLanguage Format: English Language\n\nSession Chair: Kui Wu (LightSpeed Studios) URL:https://asia.siggraph.org/2024/program/?id=papers_696&sess=sess139 END:VEVENT END:VCALENDAR
