Photorealistic rendering focuses on creating images with a computer that imitates pictures of reallife scenes as faithfully as possible. To achieve this, rendering algorithms require incorporating accurate modeling of how light interacts with various types of matter. For most objects, this model needs to account for the scattering of the light rays. However, this model falls short when rendering objects of sizes smaller or comparable to the wavelength of the incident light. In this case, new phenomena such as diffraction or interference are observed and have been characterized in optics. Digital rendering of those phenomena involve different light representations than the approximate light ray optics properties traditionally used in rendering. A first part of this work has been dedicated to creating analytical models to account for appearance phenomena which occur when light is interacting with small objects, namely, hair fibers, thin film coatings and quantum dots. A second part of this work focuses on measured material appearance models and how to find a parametrization over the appearance which can be used for editing.
