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., We present a real-time framework for rendering hair under environment lighting.
