This will require a 3D scene composed of various primitives that can be used as a rendering test bed. Think of the standard test primitives (sphere, teapot, etc.) with the red, green, yellow and checkered walls commonly used for judging lighting accuracy.
Need to support PBR, subsurface scattering, atmospheric scattering, ambient occlusion, etc.
