Chapter 17. Monte Carlo Photon Transport on the GPU
László Szirmay-Kalos, Balázs Tóth and Milán Magdics
This chapter presents a fast parallel Monte Carlo method to solve the radiative transport equation in inhomogeneous participating media for light and gamma photons. Light transport is relevant in computer graphics while higher-energy gamma photons play an essential role in medical or physical simulation. Real-time graphics applications are speed critical because we need to render more than 20 images per second in order to provide the illusion of continuous motion. Fast simulation is also important in interactive systems like radiotherapy or physical experiment design where the user is allowed to place the source and expects an instant feedback ...
