Specifically, the fbx model file of each region is processed region by region, and the fbx model file is processed to generate a lod file and output the lod file to the corresponding region folder. And simultaneously acquiring the name of each cubic box, the unique id corresponding to each area and the name of each area folder, and storing the names into a db database, wherein each area is provided with an area box, each area box has a unique name, a program generates a unique id for each area box and stores the unique id into 3dtiles, and the area name information and the corresponding id information are stored into the db database for later use.
And 208, loading the three-dimensional scene to be loaded based on the region folder.

In one embodiment, the dividing the three-dimensional scene to be loaded into at least one region according to a preset partition rule, and the drawing and labeling a corresponding cube box for each region includes:
dividing the three-dimensional scene model to be loaded into at least one region according to the service region type based on 3dmax software;
and drawing corresponding cubic boxes for the regions except the general diagram, and labeling the names of the region folders for the cubic boxes respectively.
Specifically, when a three-dimensional scene to be loaded is partitioned, a three-dimensional scene model to be loaded is partitioned into at least one region according to the service region type based on 3dmax software, for example, the scene is reasonably partitioned according to power distribution regions, alternating current regions and direct current regions with different voltage levels according to a region minimization principle, after the partitioning is completed, corresponding cubic boxes are respectively drawn for the regions except a general diagram, the names of region folders are respectively marked for the cubic boxes, each region needs to be constructed into a cubic box capable of covering the whole region through drawing, after the drawing is completed, the name corresponding to the cubic box corresponding to each region is marked, and the name is consistent with the name of the folder stored in the region file.
In this embodiment, the three-dimensional scene model to be loaded is divided into at least one region according to the service region type based on 3dmax software, then corresponding cube boxes are respectively drawn for the regions except the general diagram, and names of region folders are respectively labeled for the cube boxes, so that partitioning, drawing and labeling of the three-dimensional scene to be loaded are realized, and conditions are created for further partitioning and loading.
