Interference phenomena caused by multilayer films generates beautiful scenery. When rendering the phenomena in computer graphics, we should take into account both spectral distributions and global illumination. The paper proposes a method for rendering optical phenomena caused by multilayer films based on wave optics under global illumination environment. The method is an extension of a multilayer-film model, where the traditional model is based on a local illumination model and has limitations of rendering a scene with caustics and inter-reflection of light. In the proposed method, the multilayer-film model is reconstructed taking into account global light transport to render optical phenomena caused by interference of light under global illumination environment.
