There has NEVER been paper at #SIGGRAPH on Black, Afro-textured hair in its entire 50 year history.

UNTIL NOW.

We introduce CURLY-CUE: GEOMETRIC METHODS FOR HIGHLY COILED HAIR. When you STOP assuming straight hair is a universal baseline, lots of new science opens up.

We identify three geometric phenomena unique to highly coiled hair: phase locking, switchbacks, and period skipping.

These phenomena do NOT appear in straight hair, and thus have been ignored at #SIGGRAPH, and CGI in general, for half a century.

This is NOT another paper that shows one sad curly example after a dozen pages of straight hair. Those are obviously straight hair algorithms.

We treat hair as curly from the beginning. As a high-frequency helix, not a half-parabola.

We will present this paper at #SIGGRAPHAsia2024. More info in the Yale press release.

This work was with A.M. Darke, Alvin Shi, and Haomiao Wu.

Thanks to the Bungie Foundation, Kareem Shuman, H.D. Harris, Carvell Wallace, Elijah Richmond, and most of all, Jet Appling for making this work possible.

@TheodoreKim

Very cool! I haven’t been to SIGGRAPH since my 1990s SGI days… when hair and fur were always talked about (but indeed not curly hair).

@TheodoreKim

This looks amazing! I'm not well enough to read the paper atm but have saved it to do so when I can.

Alas, I haven't the abstract mathematical knowledge to follow formulae very well, but it looks like you've included lots of visual examples demonstrating the visible geometry, which I do tend to understand.

Thank you for exploring this. 🙂 Amazed and saddened that it hadn't been approached previously in your field.
