Surface Mesh Controlled Fast Hair Modeling

We propose a fast hair modeling method based on polygonal surface mesh editing to reduce the complexity of current hair modeling systems.First,coarse surface meshes are created to represent the overall shapes of the target hair models.Then,parameterizations are computed for these meshes to guide the strand directions.Finally,a set of hair steam-lines are generated in space to refine the final strands automatically in order to fit the expected shapes while still preserving the particular hair style effects.Experiment results show that this method can produce high-quality hair models with relatively simple mesh modeling operations.This greatly simplifies the hair modeling procedure and enhances users' ability to control the final hair shape.Furthermore,this method can be easily integrated with physical-based hair simulation technique to produce realistic hair animations.
