We present the software architecture of the global illumination renderer library and its applications. Although numerous global illumination software packages have been developed, much of the traditional design wisdom needs to be updated to support for high degrees of physical realism and performance scalability on the shared memory environments. This paper describes the design of the software architecture for efficient use of the measured BRDFs and parallel implementation on modern multi-core CPUs. This paper focuses on the realistic and flexible global illumination rendering system which generates highly realistic images in a physically-correct way. The proposed rendering system provides more flexibility, more rendering features than commercial renderers and supports physically-correct rendering using the measured reflectance data. We expect that its flexibility enables new types of applications including a system for interactive global illumination.
