Abstract

The invention provides a three-dimensional scene data storage method and device, equipment and a storage medium, and the method comprises the steps: storing a target object in each to-be-stored scene space of a target scene and bounding box information of each to-be-stored scene space into each data set corresponding to each to-be-stored scene space, wherein the to-be-stored scene space is a scene space containing all unstored objects in the target scene, the target objects are first N objects with the maximum surface area, the sum of the surface areas of the first N objects with the maximum surface area does not exceed a set threshold value, and N is a positive integer. The data storage mode breaks the strong relevance of all objects in the whole target scene and enables the objects to be stored in a scattered mode, so that scene object rendering can be carried out selectively and sequentially, and the rendering speed is improved.

Description

technical field

[0001] The present application relates to the technical field of data processing, and in particular to a method, device, equipment and storage medium for storing 3D scene data. Background technique

[0002] Scene data storage is an important processing content in scene data management, and the storage method of scene data directly affects the application effect of scene data. Especially in 3D scene management such as 3D game scenes and BIM (Building Information Modeling, Building Information Modeling) scenes, the storage of scene data directly affects the scene rendering effect.

[0003] Usually, three-dimensional scene data is stored in the form of a spatial data structure, and part of scene object information is stored in each node of the spatial data structure. When using scene data to render and display a 3D scene, it is necessary to render the entire spatial data structure. Since the rendering data is concentrated and the amount of data is large, the re...

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] The embodiment of the present application proposes a method for storing 3D scene data, see figure 1 As shown, the method includes:

[0028] S101. Obtain target scene data.

[0029] Specifically, the above-mentioned target scene may be any visual scene containing visible objects. In the embodiment of the present application, the target scene specifically refers to a three-dimensional space scene, such as a virtual 3D game interface scene, a BIM three-dimensional scene, or a V...
