We present a real-time framework for rendering hair under environment lighting. We precompute the diffuse and specular irradiance environment maps for Kajiya-Kay model with a given environment map, thus reduce the runtime shading computation to simple texture lookups, and we simulate hair self-shadowing by using offline ambient occlusion. In addition, we further achieve runtime editing of the environment map by using spherical harmonic lighting to accelerate the computation of irradiance maps.
