Real-time fast display of 3D scenes is the basic content of visual simulation and one of the core links. The object-oriented quadtree is used to organize the scene. This method saves the object information with leaf nodes, which can reduce the storage capacity and processing time of the tree and reduce the management burden of the system scene. For the visual cropping acceleration problem, it is proposed based on the line of sight. The cone partitioning cutting method can effectively improve the precision of the cutting, reduce the number of nodes participating in the cutting, and has better cutting efficiency and higher stability. The effectiveness of the method is verified by designing comparison experiments.
