This is obvious: if you view the object from a different Angle, the impostor needs to change to reflect your new viewpoint.
这显而易见的：如果你从一个不同的角度观察对象时，视点替用特效需要改变以反映你新的视点。
The second situation in which the impostor needs to be updated is when the Angle between the object and the camera view vector changes by more than a few degrees.
第二个需要更新的情形是，当对象与照相机观察矢量之间的角度发生大范围变化时。
Depending on the lighting conditions and the size of the object (s), you can view objects up to 200 feet (60 m) away with a viewing Angle of 80 degrees.
根据不同的照明条件和规模的对象(s)款，您可以查看对象达200英尺(60米)以外的视角为80度。
