Scene rendered with our framework, viewed through a polarization filter (e.g., sunglasses) and lit by sunlight and afternoon sky light. Multiple diffraction optical effects are visible: (a) the glass window and (b) moulded plastic spoke guard admit stress birefringence, which results in iridescence depending on viewing direction; and (c) the metal brake surface on the bicycle's wheels acts as an imperfect diffraction grating, dispersing scattered light. Unlike the state-of-the-art which still depends on classical materials for performance, all the materials in this scene are coherence-aware, physical optics materials, nevertheless, our rendering performance is close to classical radiometric renderers. The appearance of these materials depends on the radiometric, polarimetric, and coherence properties of light.
