Randomized trial reveals the effectiveness of sketch-based 3D hair modeling methods, highlighting convenience for users.

The aim is to create realistic 3D hair models from sketches, reducing the manual effort required for traditional modeling.
Utilized a single-image hair reconstruction pipeline and extended it to accept sketches.
Generated strand and depth maps from provided sketch and hair-region images.
Solved a diffusion equation for strand encoding and estimated depth using ControlNet.
Successfully reproduced hair geometry consistent with input sketches, showcasing versatility across sketch types.

Ishiwata et al. (2026) studied this question.
