The simulation of light constitutes the basis of digital synthesis of realistic images. This thesis addresses three important aspects of interactive physically-based image synthesis. The first part of this work presents the derivation of a mathematical model for lighting simulation including measurement, light transport, and local reflection from radiometric principles as well as for the reproduction of metameric spectra, which are indistinguishable from the simulated quantities for the human standard observer, from a colorimetric basis. This model was exemplarily validated by comparing measurements from a physical scene and an output device reproducing the result of the lighting simulation based on Monte Carlo path tracing of the respective virtual scene. Building on this validated model, the second part of the thesis introduces interactive approaches to image synthesis based on splitting light transport into global illumination simulation and evaluation. The third part of this thesis addresses the issue of incorporating data, which does not optimally fulfill the requirements of lighting simulation and reproduction, into physically-based image synthesis while maintaining photometric and colorimetric consistency.
