Simulation modeling method and system based on scene tree

Abstract

The invention discloses a simulation modeling method and system based on a scene tree, and the method comprises the steps of obtaining simulation data according to a simulation target, initializing a data structure of the simulation data, and obtaining object data and scene data included in the simulation data; constructing a scene tree according to an AABB bounding box of the environment data and the object data, performing spatial hierarchy subdivision on the constructed scene tree based on a scene tree spatial subdivision algorithm, and establishing a scene tree spatial index; establishing topological connection between the object nodes according to the scene tree spatial index and other object nodes connected with one object node in the scene tree; and after the topological connection relationship is established, writing classification information and attribute information of each object node, and establishing a simulation model. The development complexity of the object nodes can be effectively controlled while a consistent access method for the object nodes is achieved, data are stored in a centralized mode through a simulation modeling method of the scene tree, and management and visual development of the data are facilitated.

Description

technical field [0001] The invention relates to the technical field of simulation modeling, in particular to a simulation modeling method and system based on a scene tree. Background technique [0002] With the continuous development of computer simulation modeling technology, people can intuitively obtain realistic scene information, and it is also convenient for people to use simulation modeling technology to accurately analyze relevant data. The traditional object-oriented simulation modeling method abstracts the entities and components in the scene into objects with complex inheritance relationships and attributes. When the types and numbers of objects continue to increase, the interaction and communication between objects becomes more and more complex Complex and thus difficult to use and manage. Specifically, such as figure 1 As shown, through the inheritance mechanism, existing data types can be used to define new data types. The new data type defined not only has ...

Problems solved by technology

In order to create and use the object of this type of F15 fighter, the object-oriented modeling method must understand the methods and attributes of various base classes, aircraft classes, fighter classes, and F15 fighter class. With the increase of types and the deepening of inheritance levels, it is necessary to The content of the understanding increases rapidly. Facing the huge amount of data and the complex interrelationships between each data, the simulation modeling becomes more difficult. At the same time, the data after the simulation modeling is not clear enough, which is not convenient for users to analyze the data.
