一个完整的基于物理的全局照明解决方案的计算要求是显着的，目前排除了它的解决方案，甚至在一个强大的现代PC在合理的真实的时间。如果我们要实现所谓的“实时现实主义”，需要考虑的一个关键因素是，我们正在计算供人类观看的图像。虽然人类的视觉系统非常好，但它绝不是完美的。通过理解人类做了什么，或者更重要的是，没有看到什么，使我们能够节省大量的计算工作，而不会损失所得图像的感知质量。本文介绍了选择性渲染的新技术，使我们能够直接计算资源的感知重要性高的领域，同时避免计算任何细节，这将不会被观众感知。这种选择性绘制方法为我们提供了以交互速率实现复杂场景的高保真图形的真实的可能性。
The computational requirements of a full physically-based global illumination solution are significant, currently precluding its solution on even a powerful modern PC in reasonable let alone real time. A key factor to consider if we are ever to achieve so-called "Realism in Real-Time", is that we are computing images for humans to look at. Although the human visual system is very good, it is by no means perfect. By understanding what the human does, or perhaps more importantly, does not see, enables us to save significant computation effort without any loss of perceptual quality of the resultant image. This paper describes the novel techniques of selective rendering which allow us to direct computational resources to those areas of high perceptual importance while avoiding computing any detail which will not be perceived by the viewer. Such selective rendering methods offer us the real possibility of achieving high fidelity graphics of complex scenes at interactive rates.
