The divergence Angleoflight beam was measured with the method of CCD imaging and computed by second moment method.
通过CCD成像方法对准直后的光束发散角进行了测量，利用二阶矩算法计算出光束发散角。

The daytime quality oflight in forests varies with the density of the vegetation, the angle of the Sun, and the amount of cloud in the sky.
森林里的日光质量随着植被密度、太阳照射角度和天空云层数量变化而变化。

The other reason that I love these times is the angleof the light and how it can impact a scene - creating interesting patterns, dimensions and textures.
