真实的世界环境的真实感渲染在一系列不同的领域中是重要的;包括视觉特效、内部/外部建模、建筑建模、文化遗产、计算机游戏和汽车设计。目前，渲染系统能够产生许多真实世界材料外观的照片级真实感模拟。在真实的世界中，观看者对物体的感知取决于照明和物体/材料/表面特性、表面与光相互作用的方式以及光如何被表面反射、散射、吸收以及这些特性对材料外观的影响。为了重现这一点，有必要了解材料如何与光相互作用。因此，材料模型的表示和获取成为一个非常活跃的研究领域。BRDF表示和获取的最新技术概述了用于表示表面/材料反射特性的BRDF（双向反射分布函数）模型，并描述了当前用于捕获和渲染真实感材料的获取方法。
Photorealistic rendering of real world environments is important in a range of different areas; including Visual Special effects, Interior/Exterior Modelling, Architectural Modelling, Cultural Heritage, Computer Games and Automotive Design. Currently, rendering systems are able to produce photorealistic simulations of the appearance of many real-world materials. In the real world, viewer perception of objects depends on the lighting and object/material/surface characteristics, the way a surface interacts with the light and on how the light is reflected, scattered, absorbed by the surface and the impact these characteristics have on material appearance. In order to re-produce this, it is necessary to understand how materials interact with light. Thus the representation and acquisition of material models has become such an active research area. This survey of the state-of-the-art of BRDF Representation and Acquisition presents an overview of BRDF (Bidirectional Reflectance Distribution Function) models used to represent surface/material reflection characteristics, and describes current acquisition methods for the capture and rendering of photorealistic materials.
