你还可以创建一个环境光源以产生无方向性的光，或者点光源，如果你想对你场景中的特定区域聚焦。
You can also create an AmbientLight which will produce a directionless light, or a SpotLight if you want to focus on a particular part of your scene.
最后，为了消除CG效果图的虚假感，我们为所有图片增加一些色差，一些细微的装饰图案，以及光源上的一些光点和耀斑。
As final touches, aimed to eliminate some "fake CG looks", we added to all the images some chromatic aberration, a very subtle vignette, a few glows and some flare effects on the light source.
利用一点光源和一束倾斜平行光拍摄了一种离轴全息透镜，并对其傅里叶变换特性进行了分析。
The Fourier transform characteristics of off-axis hololens was discussed, which was made by using a dot light source and an inclined parallel light.
由一个点光源发出并从曲面反射或折射的光的或关于这种光的。
Of or relating to light emitted from a point source and reflected or refracted from a curved surface.
整体平行束X光透镜能把点X光源发出的发散X光束聚焦后转变成准平行X光束。
Monolithic capillary X-ray lens can collect divergent white X-ray beam emitted from a point X-ray source into a quasi parallel beam.
反射光的亮区是由线光源两端点在灯口边缘上的点反射且与测试屏交点所围成的。
The bright area of reflex is enclosed by the reflection points of two ends of linear lamp-house at the edge of orifice of lamp and points of intersection with testing screen.

结构光测距技术的主要缺点是无法获取摄像机看不到或光源照不到的点的数据。为此，采用冗余多传感器构成无影视觉坐标测量系统。
The main shortcoming of range finding technique with structural light is that it is unable to obtain the data of points which are sightless by pickup camera or can't be illuminated by light source.
