Abstract

By searching the basic tasks when photons are launched by photon mapping algorithm, this paper focuses on the implementation of photon mapping in parallel at low-end graphics workstation. It designs and implements multithreading of photon mapping under the shared memory even gets obvious acceleration ratio through a combination of OpenMP and Win32 threads library. Meanwhile, it further optimizes the parallel performance and, to some extent, improves the speed of rendering of photon mapping.
