On the other hand, in raytraced refractions, the point of a surface stroke by a light ray will return the color of its background environment, according to the rate of transparency (mixing the base color and the background environment's along with its optional filtering value) of the material and the optional index of refraction of the material, which will distort the viewing angle.

另一方面，该点将会返回它的背景环境的颜色，取决于材质的透明度（混合物体的基本颜色和背景环境）和可选的折射率。

The wave propagation and refraction of type "O" irregularities in the counter-electrojet conditions is investigated with a model electrojet in terms of the linear theory of the electrojet instability.

本文分析了反向赤道电射流条件下的不均匀性的对流放大特性。根据电射流不稳定性的线性理论，对一个分层均匀的电射流的模式的数值计算表明：在反向电射流条件下，电射流不均匀性有如下的特性：在波的传播过程中，在上电射流区内，波矢向下旋转，在下电射流区内，波矢向上旋转；在驱动电场E_D数值相同的情况下，反向电射流条件下的射线路径积分增长率r比正常电射流情况的要小得多。

Global illumination plays an important role in 3D graphics. Compared with local illumination, global illumination considers not only direct lighting, but also influence from indirect lights and occlusion. Thus, it can simulate more realistic effects, for instance, refraction and reflection of transparent objects, sub-surface scattering of translucent objects and shadow.

三维场景的全局光照计算[76~78]不仅考虑当前着色点的直接入射光照，还涉及环境中其它景物对着色点的间接光照或遮挡的影响，因而可以模拟比局部光照更真实的效果，如透明物体的折射和反射，半透明物体的子表面散射，阴影等。
