| Phosphorescence is a process where a portion of absorbed energy from light is released later as a light of lower energy and different color. Various items like glowing paints, 3D printing pigments, sticks, safety signs, or road markers are made of or are coated by phosphorescent materials.
Although phosphorescence is a visually important feature, it is not supported by current state-of-the-art renderers. To some extent, it can be approximated or faked with existing models and techniques, but these will not keep up with ever-increasing demands for fidelity - especially in the field of predictive rendering. The goal of this thesis is to allow the high-fidelity reproduction of phosphorescence effects in modern rendering systems, and to do that with reasonable performance. For this to happen, time-dependent accumulation of radiation in phosphorescent materials needs to be handled by the renderer. It is expected that the mathematical methods, in particular the extended Monte Carlo integration needed for such computations, will also be of use in different fields, e.g., prediction of thermal radiation accumulation in buildings, either from solar irradiation, or via heating. |
