Occluder is a box-shaped object that is used to cull objects' surfaces, bounds of which are not visible behind it. The surfaces behind the Occluder are not sent to the GPU, thereby saving performance.Occluder是一个框形对象，用于剔除对象的表面，其后部的边界不可见。 Occluder后面的表面不会发送到GPU，从而节省了性能。
Depending on the Back Face parameter value, the front or back faces of Occluder are used to cull surfaces. The front faces of Occluder are the sides of the Occluder that face the camera. The back faces of Occluder are the sides that are behind the front faces.根据Back Face参数值，使用Occluder的正面或背面对表面进行剔除。 Occluder的正面是Occluder面向相机的侧面。 Occluder的背面是位于正面后面的侧面。
Schematically, the Occluder faces can be shown as follows:示意性地，Occluder面可以如下所示：
Front faces of OccluderOccluder的正面
Back faces of OccluderOccluder的背面
