Real-time rendering of dynamic scenes taking into account global illumination is one of the challenging tasks in computer graphics. This paper proposes a new precomputed radiance transfer method for rendering dynamic scenes taking into account diffuse interreflection between objects. The interreflection of light between objects is calculated by considering the objects as light sources where the illumination distribution on the surface of objects, are expressed by Fourier series. This makes it possible to render dynamic scenes efficiently with diffuse interreflection whereas this is not possible using conventional precomputed radiance transfer methods. We also propose a method that runs on GPU and demonstrate that our method can render dynamic scenes with diffuse interreflection at interactive frame rates.
