RADIANCE建筑光环境分析软件

简介：

Radiance是美国能源部下属的劳伦斯伯克利国家实验室（LBNL）于上世纪90年代初开发的一款优秀的建筑采光和照明模拟软件包，它采用了蒙特卡洛算法优化的反向光线追踪引擎。ECOTECT中内\x00了Radiance的输出和控制功能，这大大拓展了ECOTECT的应用范围，并且为用户提供了更多的选择。Radiance广泛地应用于建筑采光模拟和分析中，其产生的图像效果完全可以媲美高级商业渲染软件，并且比后者更接近真实的物理光环境。

Radiance中提供了包括人眼、云图和线图\x00内的高级图像分析处理功能，它可以从计算图像中提取相应的信息进行综合处理。

功能：

Radiance is one of the most powerful daylight and electrical lighting analysis tools available since it can handle virtually any space geometry, as well as non-diffuse reflectances. The Desktop Radiance version provides the opportunity for more lighting professionals to easily access this powerful software tool through a graphical user interface. This document will describe the basic operation of Desktop Radiance 1.0 and provide some simple instructions and tips on how to construct and analyze a room model using this software. As you read through this document, you should refer to the flowchart provided in Appendix B of this document, which provides a general outline of the operations, steps, and possible analysis paths involved in applying this software to the design of daylight and electric lighting systems.

To learn more about the software, the reader should consult the Desktop Radiance User Manual, or its help utility, since it is not possible to discuss all of the relevant features and operations in this document.
