In the basis of photon texture data generated by parallelized algorithm, we propose the real-time rendering algorithm. This method stores pre-computed results of photon mapping as textures before rendering, and looks for adjacent photons by programming on GPU (graphics processing unit). The algorithm takes full advantage of the computing capacity of GPU to accelerate the process of searching photon map. The experiment has proved that this algorithm can enhance efficiency of rendering for real-time interaction, also ensure rendering effect.
