Hair paint

Adding hair to virtual humans has focused on three important aspects: hair modeling, hair animation and hair rendering. We present an easy-to-use tool for hairstyling, modeling and animation of hair in real time. For modeling we use a paint-based interface to specify geometrical and styling characteristics of hair while for animation we use a simplified physical based approximation.

1. Introduction

Methods to simulate hair in virtual humans focus on hair modeling, hair animation and hair rendering [1]. Hair modeling allows us to represent distribution, form and styling; hair animation allows us to reproduce movement and the interactions due to this movement; and hair rendering allows us to represent light interactions that cause reflections and shadows.
