Real-time rendering of human hair using programmable graphics hardware

We present a hair model together with rendering algorithms suitable for real-time rendering. In our approach, we take into account the major lighting factors contributing to a realistic appearance of human hair: anisotropic reflection and self-shadowing. To deal with the geometric complexity of human hair, we combine single hair fibers into hair wisps, which are represented by textured triangle strips. Our rendering algorithms use OpenGL extensions to achieve real-time performance on recent commodity graphics boards. We demonstrate the applicability of our hair model for a variety of different hairstyles
