Digital Salon: An AI and Physics-Driven Tool for 3D Hair Grooming and Simulation

All demos were run on either a laptop equipped with an NVIDIA GeForce RTX 4090 Laptop GPU or a desktop with an NVIDIA GeForce RTX 2080 Ti. Specifically, all computations, except for AI-image rendering, utilized 1 to 2 GB of GPU memory, depending on the size of the hair.

Our system facilitates 3D hair generation through text-based input. Upon entering a prompt, the system will provide three distinct hairstyles with variations. Users can select any of the generated options, and our system will automatically load the corresponding 3D data for further interaction.

Once a hairstyle is either loaded or generated, users can further refine it through interactive grooming. Our system supports procedural strand growth, enabling the addition of interesting facial hair like beards. Additionally, it offers procedural strand cutting to remove unwanted parts. The entire process is interactive and simulatable, providing users with real-time feedback and a realistic experience.

Our system also supports real-time hair simulation with physically plausible dynamics. The driving force can be set by numeric values, by dragging the head mesh, or through text prompts.

Leveraging advanced image generation models, our system facilitates the creation of high-quality images, where the simply shaded head and hair serves as a structural control and some additional text prompts are introduced for supplementary elements not exist in the original rendering (e.g., cloth and background). The images generated by our system maintain a close alignment with the original hairstyle and are rendered in a photorealistic manner, enabling users to quickly and reliably prototype their creations.
