Auto Hair Card Extraction for Smooth Hair with Differentiable Rendering
SessionHair & Faces
DescriptionHair cards remain a widely used representation for hair modeling in real-time applications, offering a practical trade-off between visual fidelity, memory usage, and performance. However, generating high-quality hair card models remains a challenging and labor-intensive task. This work presents an automated pipeline for converting strand-based hair models into hair card models with a limited number of cards and textures while preserving the hairstyle appearance. Our key idea is a novel differentiable representation where each strand is encoded as a projected 2D spline in the texture space, which enables efficient optimization with differentiable rendering and structured results respecting the hair geometry. Our method is evaluated on a wide range of hairstyles, including straight, wavy, curly, and coily hairs.
