Rig Becomes Hair

Uniform Box3D rods become groom volumes, locks, and a bounded chestnut mass.

Hair material study · issue #103

Hair Material Bench

Hundreds of coupled 3D guides behaving like a directed porous fluid, not seven animated ropes. Drag to orbit; enable the scissors and paint a cut directly onto the groom.

Reaction vs comb position · cyan outward · pink return

Boundary: CPU Verlet plus constraint projection; no continuum claim. Up to 21 visible fibers can interpolate each mechanical guide. Default anisotropic drag, hysteretic clumps, and crowd pressure use a bounded root-neighbor graph. The opt-in k=1 spatial lane adds sparse discovered friction only, not pressure or cohesion. *Comb force/work and spatial impulse are unit-mass solver proxies, not calibrated N/J.
