Title

Attention For Computer Graphics Rendering

Abstract

Accurate lighting computation is one of the key elements to realism in rendered images. In the past two decades, many physically based global illumination algorithms have been developed for accurately computing the light. This chapter presents a method to accelerate global illumination computation in pre-rendered animations by taking advantage of visual saliency and the limitations of the human visual system. The basic idea behind this work is that only a small fraction of a viewed scene is visually important. Thus, time can be saved significantly by terminating the computation early in areas of the image which is not visually important. A visual importance map, constructed from a saliency and visual sensitivity model, is used to accelerate rendering. The results indicate an order of magnitude improvement in computational speed. © 2005 Elsevier Inc. All rights reserved.
