项目摘要

Global illumination brings realistic and detailed lighting environments to Computer Graphics imagery at the expense of very high computational cost. Although most people are unaware, they experience its imagery when they have renderings of a new kitchen design, in public displays of new architecture, and in a variety of film, advertising and entertainment. The computer imagery produced by this technique can deliver the highest form of realism achievable by Computer Graphics as it models indirect light (reflected from other surfaces) and not just light direct from light sources in the scene.Such realism is now a standard requirement for the above applications and it is also gaining popularity in the virtual reality and scientific visualization communities as the advantages of increased perception and understanding are now recognised and outweigh the disadvantages of production time.Current approaches for fast global illumination place limits on the scene geometry, depth of light paths, numbers of samples, or the materials in the scene. Within these limitations it is possible to employ large caches for computation reuse (only in static scenes), or create simplified algorithms on the GPU, but always at the cost of reducing rendering accuracy.The aim of this research is to work towards real-time and accurate global illumination techniques by exploring new approaches to biased rendering methods. We will apply hierarchical techniques, clustering, ray and photon statistics and information, edge detection and combine other appropriate techniques to reduce the complexity and computation of global illumination whilst maintaining or enhancing visual accuracy.These improved timings and render quality will be demonstrated within a software package. The improved algorithms will allow the above application areas to produce higher quality images at reduced cost.
全局照明以非常高的计算代价为计算机图形学图像带来了逼真和详细的照明环境。尽管大多数人没有意识到,但当他们有新厨房设计的效果图时,在新建筑的公开展示中,在各种电影、广告和娱乐中,他们都会体验到它的形象。通过这种技术产生的计算机图像可以提供计算机图形学所能实现的最高形式的真实感,因为它模拟间接光(从其他表面反射),而不仅仅是场景中的光源直接光。这种真实感现在是上述应用的标准要求,它在虚拟现实和科学可视化社区中也越来越受欢迎,因为人们现在认识到了增加感知和理解的优点,并超过了制作时间的缺点。目前的快速全局照明方法对场景几何形状、光路深度、样本数量或场景中的材料进行了限制。在这些限制下,可以使用大的缓存来重复使用计算(仅在静态场景中),或者在GPU上创建简化的算法,但总是以降低渲染精度为代价。本研究的目的是通过探索新的偏向渲染方法来实现实时和准确的全局光照技术。我们将应用分层技术、聚类、光线和光子统计和信息、边缘检测和其他适当的技术来降低全局照明的复杂性和计算量,同时保持或提高视觉精度。这些改进的计时和渲染质量将在一个软件包中演示。改进的算法将允许上述应用领域以更低的成本产生更高质量的图像。
