Ray tracing, used during generating realistic images, is systematically introduced in this article. And some improving methods are given for shadow test and antialiasing.
本文对逼真图形生成过程中所使用的光线跟踪法作了系统的介绍，并对其中的阴影测试及抗阶梯效应的几种改进方法作了说明。
My post " Ten Reasons Why 'Professional Librarian' is an Oxymoron" was an experiment in shadow boxing—an opportunity to challenge myself, and to put my own beliefs to the test.
我发了一篇题为“‘专业图书馆员’是个自相矛盾的概念的十个理由”的帖子，这是一个假想的辩争——或者说是给自己设下的一个辩题，以检验我自己关于这些问题的信念。
Shadow chancellor George Osborne said the real test of the measure would be whether lending was resumed.
影子财相乔治(GeorgeOsborne)表示，措施的正真考验是，贷款会否得到恢复。

图 7是一个线图，显示了测试的数据库中的一些信息，添加了一个徽标、阴影效果和测试的统计表。
The distribution of improved LBP texture is discussed and a significant test is performed to classify each moving pixel into foreground object or moving shadow according to this theory.
通过分析阴影的物理模型，得出局部纹理的光照不变性，利用基于比值判决的LBP纹理法来区分运动车辆和阴影，并应用亮度约束和几何启发式准则进一步改善阴影检测效果。
The key techniques of the rendering of vector data over 3d terrain based on stencil shadow volume algorithm are detailed and the effectiveness of this method is test-proven.
详细论述了基于模板阴影体算法矢量数据绘制的关键技术，并通过试验验证了该方法的有效性。
To test which areas are in light and which are in shadow, you can cast a shadow with a pencil on the object.
注意中央光和高光的位置是不一样的。明暗交界线是物体从亮部转入暗部的区域。这个就是光线和表面相切。
