Abstract : Rendering the structural color of natural objects or modern industrial products in the 3D environment is not possible with RGB-based graphics platforms and software and very time consuming, even with the most efficient spectra representation based methods previously proposed. Our framework allows computing full spectra light object interactions only when it is needed, i.e. for the part of the scene that requires simulating special spectra sensitive phenomena. Achieving the rendering of complex scenes with both the full spectra and RGB light and object interactions in a ray-tracer costs only some additional fractions of seconds. To prove the efficiency of our framework, we implemented a “Multilayer Film” in a simple ray-tracer. However, the framework is convenient for any complex lighting model, including diffraction or fluorescence.
