Simulation and Rendering of Wave-Based Optical Material Properties

Wave-based optical phenomena such as interference and diffraction produce vivid colors when observed in the real world. However, the current state of the art in computer graphic modeling of these phenomena is fairly limited. This project was intended to generate a data structure representing a Bidirectional Reflectance Distribution Function (BRDF) by simulating optical wave phenomena on a small scale, and by using a ray-based simulation to integrate many different wave simulations together. The researchers developed a method of collecting the reflectance data using a data-driven BRDF, which would allow them to more accurately create images that display the result of diffraction and interference, and through them, to more complicated and possibly as-yet unseen physical structures.
