In this embodiment, the data of the original structure further includes: the type of structure, the location or coordinates of the structure, the rotational quaternion of the structure, raw data, etc., wherein the raw data includes materials, construction units, etc., but is not limited to the above.
A wireless mesh network (mesh) of structures can be rendered by the outer bounding box of the original structure and the location of the original structure.
In yet another alternative embodiment of the present invention, step 12 may comprise:
step 121, drawing twelve triangular surfaces of the original structure according to preset coordinates of an outer bounding box of the original structure, wherein the preset coordinates of the outer bounding box of the original structure at least comprise the following two coordinates:
highest point coordinates and lowest point coordinates within all coordinates of the outer bounding box of the original structure.
In this embodiment, any point may be taken from all coordinates of the outer bounding box of the original structure to obtain the highest coordinate (maxX, maxY, maxZ) and the lowest coordinate (minX, minY, minZ) of the outer bounding box.
In yet another alternative embodiment of the present invention, step 121 may comprise:
step 1211, obtaining corresponding eight range coordinates according to the highest point coordinate and the lowest point coordinate;
step 1212, in the same cartesian coordinate system, for any four range coordinates, executing a first operation until all planes in the cartesian coordinate system are divided into two triangles with equal area, to obtain twelve triangular faces of the original structure;
the first operation is:
step 12121, selecting three range coordinates clockwise connecting lines from the four range coordinates to form a first triangular surface;
step 12122, clockwise connecting the unselected range coordinates with the two points corresponding to the hypotenuse of the first triangular surface to obtain a second triangular surface.
As shown in fig. 2, in this embodiment, the following describes a method of drawing a cube in a specific example:
firstly, assuming that after obtaining the highest coordinates (maxX, maxY, maxZ) and the lowest coordinates (minX, minY, minZ) of the outer enclosure box of a certain structure, the lowest coordinates are used as the first vertex of the pre-generated cube, that is, the point 1(minX, minY, minZ) in fig. 2 corresponds to, then the highest coordinate point 7(maxX, maxY, maxZ) of the structure;
next, after obtaining the lowest coordinate point 1 and the highest coordinate point 7 of the structure, the coordinates (X, Y, Z) of the two points are arranged and combined to obtain 8 coordinates of the pre-generated cube, which correspond to the points 1 to 8 in fig. 2, that is: point 1(minX, minY, minZ), point 2(maxX, minY, minZ), point 3(maxX, maxY, minZ), point 4(minX, maxY, minZ), point 5(minX, minY, maxZ), point 6(maxX, minY, maxZ), point 7(maxX, maxY, maxZ), point 8(minX, maxY, maxZ).
Then, after obtaining 8 vertex coordinates of the pre-generated cube, 6 faces of the pre-generated cube may also be obtained, and in each face, twelve triangular faces of the cube are constructed according to the clockwise connecting line in fig. 2, but the construction method is not limited to the method of connecting lines clockwise as in the drawing.
In fig. 2, the front face of the pre-generated cube is taken as an example, two triangular faces 1-5-6 and 6-2-1 are formed, and the clockwise direction is selected to form the triangular faces. The same procedure was used to obtain a total of 12 other 5 faces of the pre-generated cube, which were: 1-5-6, 6-2-1, 2-6-7, 7-3-2, 7-8-4, 4-3-7, 4-8-5, 5-1-4, 5-8-7, 7-6-5, 4-1-2, 2-3-4.

and 131, splicing every two triangular surfaces corresponding to the oblique edges of the twelve triangular surfaces to obtain a spliced frame structure, wherein the spliced frame structure is a cubic structure.

In a further alternative embodiment of the invention, the position of the frame structure is the same as the position of the original structure.
In this embodiment, since the position of the original data is included when the data of the original structure is acquired, and the conversion is performed in the original position when the original structure is converted, the position of the frame structure is the same as the position of the original structure.
In still another optional embodiment of the present invention, after step 13, the method may further include:
step 132, replacing the original structure not meeting the preset rule with the frame structure when the mobile device displays, and reserving the original structure meeting the preset rule.
In this embodiment, the preset rule may be set according to an actual situation, for example: the original structure may be set within a range of 100 meters from the origin of the mobile device in the mobile device, and the frame structure may be set outside the range of 100 meters, or the frame structure may be set in the mobile device with a larger occupied memory, and the original structure with a smaller memory, but the above two are merely two examples, and the preset rule includes but is not limited to the above.
Fig. 4 shows a flowchart of a specific method for implementing a multiple level of detail (LOD) display on data in a super-large space according to an embodiment of the present invention, where as shown in fig. 4, the large space is divided into at least two blocks, each block includes corresponding component information, and a mesh of a component can be drawn through the information. Thus, the number of triangular faces of each member is 12, and LOD display of a large number of models can be satisfied.
The method has the core functions that: and generating a cube by using the constructed outer bounding box data. The resulting cube was used to simulate a member in a low-modulus state, wherein the member corresponds to the structure in the above-described embodiment.
The specific method comprises the following steps:
first, the model is split. The model splitting can be divided into two stages, firstly, the same building blocks are classified by analyzing the structure of the BIM model, and a classified JS Object numbered Notation (JSON) file is generated in the stage; secondly, exporting the BIM into a data file consisting of a three-dimensional model and large space data information of all components through a json file, wherein the data structure of the large space data comprises data of an outer bounding box.
Second, all required low modes can be generated after obtaining large spatial data of all models. The outer bounding box of each member is two coordinate points: the lowest point coordinates (minX, minY, minZ) and the highest point coordinates (maxX, maxY, maxZ) of the model in the coordinate system. The model mesh rendering method is provided by Unity, namely 8 vertexes and 12 triangular faces of a specified cube are generated into the cube.
Finally, when the program is started, the position of the camera is the origin. With the movement of the user control equipment, the coordinates of the camera dynamically change, only high-precision models in a small range around the camera need to be loaded according to the coordinates of the camera, and models outside the range are replaced by low models, so that the requirement that the user checks nearby models around can be met, the position of the user in a large space can be known, and the subsequent movement and operation are facilitated.
