Techniques to simulate hair in virtual humans focus on hair modeling, hair animation and hair rendering. We propose a system for modeling and animating   in real time using standard OpenGL on commodity graphic cards. For styling, we propose a paint tool to determine a set of gray scale images that allow us to establish hair density and hair length values, as well as other useful parameters,  and for animation, we use a simplified physically based method that computes physics only on some hairs, which we call basis hairs, calculating other dependent hairs from them.
