For Spot and Point lights, shadow resolution determines shadow map size. Additionally, for lights that cover small area on the screen, smaller shadow map resolutions are used.

对于聚光灯和点光灯，阴影分辨率决定了阴影贴图大小。此外，对于在屏幕上覆盖小面积的灯，使用较小的阴影贴图分辨率。

Then the diffraction spot size is decreased, and the optical resolution is increased, so the accuracy of the fine tracking system is improved.

由此减小接收衍射光斑的大小，提高系统的光学分辨能力，从而提高精跟踪系统的精确性。
