For example, in addition to the location, direction, and color of the light, it's possible to control the Angle of the spotlight cone and the center bias of the cone.
例如，除了位置、方向和光线颜色，它还能够控制spotlight锥角和锥体离心值。
For example, insects can see polarised light - light to them appears as different colours, depending on the Angle at which reflects off different surfaces.
例如，昆虫能够看到极光——光对它们来讲会根据从不同的表面反射的不同角度而显现出不同的颜色。
For maximum polarization, the incoming light must have an incident Angle of 30 degree, and the camera is aimed at the subject at an Angle of 30 degree from the other side (see image below).
为了获得最大的两极分化，入射光中必须有一个30度角的事件，和相机的目的是在一个主题侧面30度角的其他从(见以下图片)。
