Modeling 3D hairs based on dynamic super-helices
基于动态超螺旋线的三维头发建模

Simulating human hair is recognized as one of the most difficult tasks in computer animation.The concept that each strand was represented by a Super-Helix was presented to solve the nonlinear behavior of hair strands with respect to bending and twisting, based on the Kirchhoff equations for dynamic, inextensible elastic rods. Hair grand was divided into N pieces,which each piecewise helical rod which was animated using the principles of Lagrangian mechanics.At last, each piece would be connected to constitute the entire hair grand. A series of experiments based on the comparison of other realistic models for dynamic hair and dynamic Super-Helix, which shows that the model efficiently handles a wide range of curls with a high level of realism.
