Roaming of large urban scenes based on Unity 3D

摘要

The core issues of urban scene roaming include block reorganization of large amounts of data and dynamic scheduling of data during the runtime of the scene. Aiming at the problems above mentioned, This paper designs an undirected graph data structure organization method of the data. According to the characteristics of Unity 3D engine, it provides the client's scheduling strategy. The article analyzes the rationality of the method and provides a method for constructing a graphic structure. This method allows the data to be searched from near to far depending on the position of the viewpoint, and reduces the amount of data computations when the scene is running. Experiments show that this method can make the scene run smoothly.
