Abstract: Hair rendering and simulation is a fundamental part in the representation of virtual characters. But intensive calculation for the dynamic on thousands of hair strands makes the task much challengeable, especially on a portable device. The aim of this short paper is to solve the problem of how to perform real-time hair simulation and rendering on mobile device. In this paper, the process of hair simulation and rendering is adapted according to the property of mobile device hardware. To increase the number of hair strands of simulation, we adopted the Dynamic follow-the-leader (DFTL) method and altered it by our new method of interpolation. We also pictured a rendering strategy basing on the survey of the limitation of mobile GPU. Lastly we present an innovational method that carried out order independent transparency at a relatively inexpensive cost.
