Fast Rendering Algorithm of Underwater Optical Effect

Underwater optical effect simulation is an important component of simulating underwater scene. This paper will present a fast rendering algorithm of underwater optical effect based on Iwasak′s method. It simplifies the illumination volume to reduce the light calculation and uses the Gouraud shading method to render each side of every illumination volume. The experiments show that it can reduce the CPU calculation time and increase the rendering speed. The rendering results get a higher frame-rate with better quality.
