We introduce a way of implementing physically-based renderers that can switch rendering methods with a raytracing library. Various physically-based rendering (PBR) methods can generate beautiful images that are close to human view of real world. However, comparison between corresponding pairs of pixels of image pairs generated by different rendering methods is necessary to verify whether the implementation correctly obeys mathematical models of PBR. For comparison, result images must be same scene, same resolution, from same camera angle. We explain fundamental theory of PBR first, and present overview of a library for PBR, Embree, developed by Intel, as a way of rendering-switchable implementation. Finally, we demonstrate computing result images by a renderer we developed. The renderer can switch rendering methods and be extended for other method implementations.
