HairDeck

HairDeck is an AI tool that generates animation-ready stylized hair cards and spring-bone chains from a single image.

HairDeck is an open-source software tool that creates stylized hair cards and spring-bone animation chains from a single input image. It uses a card VAE and conditional set diffusion to generate hairstyles as a set of tokens, preserving individual cards with per-card UV coordinates. A chain diffusion model then generates the bones needed to drive the cards, enabling skinning and VRM export. The software is designed for 3D artists and developers working with character models. It supports GLB mesh and VRM exports, and runs locally with a Gradio web interface or command-line scripts.
