Realistic Image Synthesis Using Photon Mapping (Paperback)

The creation of photorealistic images of three-dimensional models is central to computer graphics. Photon mapping, an extension of ray tracing, makes it possible to efficiently simulate global illumination in complex scenes. Photon mapping can simulate caustics (focused light, like shimmering waves at the bottom of a swimming pool), diffuse inter-reflections (e.g., the bleeding of colored light from a red wall onto a white floor, giving the floor a reddish tint), and participating media (such as clouds or smoke). This book is a practical guide to photon mapping; it provides both the theory and the practical insight necessary to implement photon mapping and simulate all types of direct and indirect illumination efficiently.

在電腦圖學中，創建逼真的三維模型影像是至關重要的。光子映射是對光線追蹤的擴展，可以在複雜場景中高效模擬全局照明。光子映射可以模擬焦散光（例如游泳池底部閃爍的波浪般的光線）、漫反射互反射（例如從紅色牆壁上流出的彩色光線在白色地板上產生紅色色調）、以及參與媒介（例如雲或煙）。本書是光子映射的實用指南，提供了實施光子映射並高效模擬各種直接和間接照明所需的理論和實踐見解。
