Abstract

This paper presents an intuitive sketching interface for interactive hairstyle design, made possible by an efficient numerical updating scheme. The user portrays the global shape of a desired hairstyle through a few 3D style curves which are manipulated by interactively sketching freeform strokes. Our approach is based on a vector field representation which is obtained by solving a sparse linear system with the style curves acting as boundary constraints. The key observation is that the specific sparseness pattern of the linear system enables an efficient incremental numerical updating scheme. This gives rise to a sketching interface that provides interactive visual feedback to the user. Interesting hairstyles can be easily created in minutes.
