The occlusion culling process will go through the scene using a virtual camera to build a hierarchy of potentially visible sets of objects.
遮挡剔除的运行将通过在场景中使用一个虚拟的摄像机来创建一个物体潜在可视性状态(set)的层级。
In the embedding step, four points are specified to build the world coordinate system so that the virtual objects are superimposed on the real scene images in the proper positions.
在嵌入阶段，我们指定了四个点来建立世界坐标系，以确保虚拟物体能够成功叠加到真实场景中的正确位置。
