GPU-based Interactive Real-time Parallel Algorithm for Rendering Underwater Optical Effects

摘要

Graphics Processing Unit (GPU) has evolved into a highly parallel component for its massive multithread architecture over the past decade. This paper will present a GPU-based interactive real-time parallel algorithm for rendering underwater optical effects based on Iwasaki's method using Compute Unified Device Architecture (CUDA). The algorithm is implemented with parallel operations by CUDA programming model on GPU. Compared to conventional sequential computation, the method can achieve realtime interactive experience without any sacrifice on image quality. Experiment results show that it can greatly reduce the CPU calculation time, and get a higher frame rate.
