如果您在室内并在纸上阅读本文档，则页面可能会被荧光灯泡照亮。灯泡内的气体吸收高能电子，然后发出荧光，或者以不同的频率重新辐射吸收的能量。普通荧光灯泡中的特定气体被选择为在可见波长中有效地再辐射这种能量。如果您是在线阅读本文档，那么您可能是在阴极射线管（CRT）上阅读的。阴极射线管的表面衬有磷光体，磷光体吸收指向它们的高能电子，并随着时间的推移逐渐释放出可见波段的能量。荧光和磷光这两种现象不像简单的反射和透射那样常见，但在完整描述宏观物理行为方面确实发挥了重要作用，这些行为应该由图像合成程序建模。本文提出了一个包含这些现象的全局能量平衡的数学模型。
If you are indoors and reading this document on paper, then the page may be lit by a fluorescent light bulb. The gases inside the bulb absorb high-energy electrons, and then fluoresce, or re-radiate that absorbed energy at a different frequency. The particular gases in common fluorescent bulbs are chosen to be efficient at re-radiating this energy in the visible wavelengths. If you are reading this document on-line, then you’re probably reading it on a cathode-ray tube (CRT). The face of the CRT is lined with phosphors, which absorb the high-energy electrons directed at them, and gradually release that energy over time in the visible band. The two phenomena of fluorescence and phosphorescence are not as common as simple reflection and transmission, but do have an important part to play in the complete description of macroscopic physical behavior that should be modeled by image synthesis programs. This paper presents a mathematical model for global energy balancing which includes these phenomena.
