| Abstract: |
| To support hairstyling effectively, it’s crucial for hairstyling tools to find a tradeoff between realism and interaction. This paper presents an interactive hairstyling method which can handle both global and local details of the hairstyle. Vector field based hairstyling method is used to generate the global shape of the hairstyle. This paper defines three different kinds of hairstyle curves which indicate the boundary constraints of vector field so that the user can control the hairstyle generation interactively. Hair wisp model is also used to represent hairstyles and several wisp based editing operations are defined, such that users can control the local details of the hairstyle. Experimental results prove that the proposed method provides more interaction and computation efficiencies without lost of hair realism. |
