Description
Summary:碩士 === 國立臺灣大學 === 資訊工程學研究所 === 97 === We present an algorithm for rendering global illumination while the scene, camera, and light sources can be fully dynamic. We achieve this by generating an occlusion map of each pixel on screen and take the occlusions as indirect light sources to produce the global illumination effects. By exploiting the occlusion map, global illumination effects including soft shadow, reflective lighting, and multi-bounce lighting can be produced by iteratively rendering process. We have approximated the rendering equation and accelerate it to interactive rate.
