    Rendering hair with global illumination



     Simulating realistic lighting conditions using global illumination techniques is essential for realistic rendering. Hair rendering using only direct illumination in scenes rendered with global illumination techniques creates inconsistencies in the overall appearance. Global illumination techniques that are based on radiosity and ray-tracing cannot directly be applied to hair rendering, since even a single object with hair can be more complex than the rest of the scene. We propose a framework for rendering hair with global illumination. We also introduce simplification techniques to achieve more than two orders of magnitude faster global illumination with hair.
