Strand-Aligned 3D Gaussians Enable Strand-Level Hair Reconstruction
TinfoilTricorn · x · 2026-10-17
A new hair reconstruction paper proposes strand-aligned 3D Gaussians:
- A 3D line lifting scheme that lifts 2D orientation maps into a 3D field while refining camera parameters
- A dual representation of hair strand polylines and 3D Gaussians for differentiable rasterization with photometric constraints
- A coarse-to-fine, prior-guided optimization combining latent and explicit hairstyle representations
