The present application provides a method for constructing a three-dimensional heat model, and relates to an apparatus for constructing a three-dimensional heat model, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.

The construction method of the three-dimensional heat model provided by the application is described with reference to fig. 1 and 2.

Referring to fig. 1 and 2, fig. 1 is a flow chart illustrating a method for constructing a three-dimensional heat model according to an embodiment of the present application, and fig. 2 is a schematic structural diagram illustrating a three-dimensional heat model according to an embodiment of the present application; where fig. 2 includes fig. 2 (a) and 2 (b), fig. 1 includes steps 102 through 108.

Step 102: and acquiring two-dimensional coordinate data of a service dimension and heat data corresponding to the two-dimensional coordinate data.

In an implementation of the present application, the service dimension refers to that in the method for constructing the three-dimensional heat model, a process of constructing the three-dimensional heat model is performed in the same service dimension, and the constructed three-dimensional heat model is used for reflecting a distribution situation of heat data in the same service dimension; the business dimension can be used for counting the population distribution in a certain city, can be used for counting the age distribution of the browser in a certain website, and can be used for counting the income distribution of each department in a certain enterprise.

The method for constructing the three-dimensional heat model is described by taking the service dimension as the statistic of population distribution in a certain city, wherein the two-dimensional coordinate data of the service dimension can be the longitude and the latitude of the city, and the heat data corresponding to the two-dimensional coordinate data is the population number at each longitude and latitude.

Based on this, under the condition of counting the population distribution in the service dimension, a statistical graph for counting the population distribution in the service dimension can be determined according to the attribute information of the service dimension, and the statistical graph can be drawn according to the determined statistical graph and the population distribution corresponding to the service dimension, so that the specific distribution condition of the population in the service dimension can be specifically known according to the drawn statistical graph.

In the construction method of the three-dimensional heat model, in order to more intuitively embody the distribution condition of the distributed uniform data in the three-dimensional coordinate space, the planar grid consisting of the planar grid units corresponding to the two-dimensional coordinate data can be obtained by acquiring the two-dimensional coordinate data of the business dimension and the heat data and performing gridding processing on the two-dimensional coordinate data, the coordinate distribution condition of the business dimension in the two-dimensional coordinate space can be determined according to the two-dimensional coordinate data corresponding to the business dimension, the height data of the planar grid units in the three-dimensional coordinate space can be determined according to the height data, the three-dimensional heat model is constructed through a blueprint processing interface based on the height data and the planar grid, the specific distribution condition of the heat data of the business dimension is constructed in the three-dimensional coordinate space through a phantom engine, and the heat condition of each type of data of the business can be embodied according to the longitudinal height of the constructed three-dimensional heat model, so that a user who views the business can visually understand the change condition and the change trend of the business data among the longitudinal height of the three-dimensional heat model.

Specifically, under the condition that a three-dimensional heat statistical graph needs to be drawn on the data of the service dimensions, two-dimensional coordinate data needed for drawing the three-dimensional heat statistical graph and heat data of each two-dimensional coordinate data in the service dimensions are obtained.

For example, the service dimension is the population distribution situation of each area in the statistical first city, a corresponding three-dimensional heat map is drawn, each area in the first city is determined as an area, each area is divided into a plurality of small areas according to a set dividing mode, the center of the first city is used as the origin of a two-dimensional coordinate, the coordinate point of each small area in the two-dimensional coordinate is determined, the coordinate point of each small area is the two-dimensional coordinate data of the statistical population distribution situation, otherwise, the two-dimensional coordinate data is represented as the coordinate point of each area in the map, and the population number contained in each small area is the heat data in the statistical population distribution situation.

Step 104: and carrying out gridding processing on the two-dimensional coordinate data to obtain a plane grid consisting of plane grid units corresponding to the two-dimensional coordinate data.

Specifically, on the basis of obtaining the two-dimensional coordinate data of the service dimension and the two-dimensional coordinate data, the two-dimensional coordinate data is further subjected to gridding processing to obtain a planar grid unit formed by the two-dimensional coordinate data, and then the planar grid is formed by all the planar grid units.

In specific implementation, the gridding process is to determine two-dimensional coordinate points corresponding to each two-dimensional coordinate data according to the two-dimensional coordinate data, connect each two-dimensional coordinate point according to the polygon of the planar grid unit, so as to obtain a plurality of planar grid units formed by the two-dimensional coordinate points, and the planar grid units share one edge and the same point, so as to form a planar grid, wherein the planar grid units can be polygons such as a triangle, a quadrangle, or a pentagon, the formed screen slow grid is formed by polygons such as a triangle, a quadrangle, or a pentagon, and only one polygon is formed in one planar grid.

On the basis of obtaining the planar mesh, further, in one or more embodiments of this embodiment, the planar mesh may be composed of one type of polygon, and the specific implementation manner is as follows:

Specifically, first, two-dimensional coordinate points corresponding to the acquired two-dimensional coordinate data are determined in a two-dimensional coordinate space, and polygons to which planar grid cells constituting the planar grid belong are determined according to the meshing rule, where the meshing rule specifies a polygon to which planar grid cells constituting the planar grid belong; and determining the polygons which form the planar grid units, connecting adjacent two-dimensional coordinate points to form a plurality of polygons which are the same as the polygons which form the planar grid units, and forming the planar grid by using the plurality of polygons.

For example, the two-dimensional coordinate data corresponds to 4 two-dimensional coordinate points, the gridding rule is a triangle to which the planar grid unit belongs, 4 triangles with 4 coordinate points as vertexes can be obtained by connecting the 4 coordinate points, the 4 triangles share two sides, two triangles sharing the same side are selected as the planar grid unit, and a quadrangle formed by the two triangles is the planar grid formed by the planar grid units corresponding to the two-dimensional coordinate data.

In addition, when the gridding rule is a quadrangle to which the planar grid unit belongs, four adjacent two-dimensional coordinate points are connected to form a quadrangle, and when the next quadrangle is connected, one side of the obtained quadrangle is required to be used as the side of the next quadrangle, so that the planar grid formed by the planar grid unit is ensured to be formed by a plurality of quadrangles; in the case that the gridding rule is a pentagon to which the planar grid unit belongs, the process is similar to the process of forming the planar grid by using the quadrilateral planar grid unit, and the description is omitted here.

On the basis of obtaining the planar mesh, further, in one or more embodiments of this embodiment, planar mesh units may be obtained through a triangulation algorithm, and then the planar mesh is composed of the obtained planar mesh units, which is specifically implemented as follows:

and generating the plane mesh according to the plane triangular mesh unit.

Specifically, the two-dimensional coordinate data of the service dimension is subjected to meshing processing through the triangulation algorithm, the obtained planar mesh unit is a triangle, namely the planar triangular mesh unit, and the planar mesh is generated according to the obtained planar triangular mesh unit.

Performing gridding processing on the two-dimensional coordinate data through the triangulation algorithm (also called Delaunay triangulation), wherein two important criteria need to be met; first, the empty circle characteristic: in the two-dimensional coordinate points corresponding to the two-dimensional coordinate data, the formed Delaunay triangulation network is unique (namely any four points cannot be in a common circle), and no other points exist in the range of the circumscribed circle of any triangle in the Delaunay triangulation network; secondly, the minimum angle characteristic is maximized, in the triangulation formed by the Delaunay triangulation in the two-dimensional coordinate points corresponding to the two-dimensional coordinate data, the minimum angle of the triangle formed by the Delaunay triangulation is the largest, namely the triangle is the planar grid which is closest to regularization in the Delaunay triangulation, specifically the diagonal of the convex quadrangle formed by two adjacent triangles, and after mutual exchange, the minimum angles of the six interior angles are not increased.

The triangulation algorithm is adopted to conduct gridding processing on the two-dimensional coordinate data, the formed plane mesh is formed by plane triangular mesh units and generated to be a progressive mesh, a three-dimensional heat model constructed subsequently can have regularity and uniqueness according to the characteristics of the triangulation algorithm, and a three-dimensional heat map generated through an illusion engine is good in display effect.

Step 106: and determining corresponding height data of each plane grid unit in the plane grid in a three-dimensional coordinate space according to the heat data.

Specifically, on the basis of obtaining the planar grid formed by the planar grid units corresponding to the two-dimensional coordinate data, further, the planar grid is formed by the planar grid corresponding to the two-dimensional coordinate data, each two-dimensional coordinate data corresponds to heat data, and then height data of each planar grid unit in the planar grid in a three-dimensional coordinate space is determined according to the heat data of each two-dimensional coordinate.

The height data is a longitudinal height value of the heat data in a three-dimensional coordinate, for example, when the heat data is the number of people in each location, 50 people exist at the location a, the two-dimensional coordinate data of the location a corresponds to a coordinate point (3,3), each unit in the three-dimensional coordinate space represents 10 people, then the height data of the location a in the three-dimensional coordinate space is 5, and the corresponding three-dimensional coordinate point is (3,3,5).

On the basis of determining the height data of each planar grid cell, further, in one or more implementations of this embodiment, a specific determination process of the height data is as follows:

Specifically, three-dimensional coordinate data mapped in the three-dimensional coordinate space by each planar grid cell is obtained by converting heat data corresponding to the two-dimensional coordinate data and two-dimensional coordinate data corresponding to the planar grid cells included in the planar grid, for example, if a coordinate point corresponding to the two-dimensional coordinate data is (1,1), the coordinate point is converted into three-dimensional coordinate data in the three-dimensional coordinate space as (1,1,0), where x-axis and y-axis coordinates are kept unchanged, when the coordinate point is converted into the three-dimensional coordinate space, a z-axis coordinate is added, the z-axis coordinate is determined as a default value of 0, and if the heat data corresponding to the (1,1) coordinate point is converted into coordinate data, where the heat data of the point is 1, the z-axis value in the three-dimensional coordinate space is converted into 1, the coordinate point in the three-dimensional coordinate space is (1,1,1), where the coordinate point is three-dimensional coordinate data, and the z-axis value is the three-dimensional coordinate data in the coordinate space.

In addition, on the basis of determining the height data corresponding to each planar grid cell in the three-dimensional coordinate space according to the three-dimensional coordinate data mapped by each planar grid cell in the three-dimensional coordinate space, further, in one or more embodiments of this embodiment, it is necessary to determine the three-dimensional grid cell in the three-dimensional coordinate space first, and then determine the height data of each planar grid cell, and a specific implementation manner is as follows:

Specifically, three-dimensional coordinate data mapped in the three-dimensional coordinate space by each planar grid unit is determined, a three-dimensional grid unit in the three-dimensional coordinate space by each planar grid unit is determined, and the corresponding height data of each planar grid unit in the three-dimensional coordinate space is determined according to the three-dimensional grid unit in the three-dimensional coordinate space by each planar grid unit.

In practical applications, taking planar grid cells as triangles, and the coordinate points corresponding to the two-dimensional coordinate data of each vertex of the triangle are a (0,1), B (0,0) and C (1,0), and the thermal data corresponding to each two-dimensional coordinate data is a 10, B20 and C30, for example, the height data of each planar grid cell is determined in a three-dimensional coordinate space, where in the three-dimensional coordinate space, the coordinate points corresponding to the two-dimensional coordinate data a, B and C in the three-dimensional coordinate space are A1 (0,1,1), B1 (0,0,2) and C1 (1,0,3), respectively, and according to the three-dimensional coordinates of A1, B1 and C1 in the three-dimensional coordinate space, a slope A1B1C1 is determined to be formed in the three-dimensional coordinate space, and the slope A1B1C1 has a relationship with the planar coordinate data in the two-dimensional coordinate space, namely, ABC 1 in the three-dimensional coordinate space, ABC 1 and ABC 1 in the three-dimensional coordinate space, and the height data of the slope A1 and C1 in the three-dimensional coordinate space.

In specific implementation, under the condition that the inclined plane corresponding to each plane grid unit is determined in the three-dimensional coordinate space, because the plane grid units share the same edge, the inclined planes determined by each plane grid unit in the three-dimensional coordinate space are mutually connected, and because the height data are inconsistent, a three-dimensional grid frame with wave vision is spliced.

According to the heat data of each planar grid unit and the vertex two-dimensional coordinate data of each grid unit, the three-dimensional coordinate data of each vertex of each grid unit in the three-dimensional coordinate space can be determined in the three-dimensional coordinate space, so that the inclined plane having a mapping relation with each planar grid unit can be determined in the three-dimensional coordinate space, a basic frame can be provided for subsequently constructing the three-dimensional heat model, and the construction efficiency of constructing the three-dimensional heat model is improved to a great extent.

Step 108: and selecting the plane grid and the height data by calling a blueprint processing interface to construct a three-dimensional heat model of the service dimension.

Specifically, on the basis of determining the height data of each planar grid cell in the planar grid according to the heat data, further, according to the obtained height data of each planar grid cell in the planar grid and the planar grid, a three-dimensional heat model of the service dimension is constructed through a blueprint processing interface in an illusion engine; wherein the three-dimensional heat model is a frame of a three-dimensional heat map to be rendered, having exhibited the outline of the business dimension in a three-dimensional coordinate space.

The blueprint processing interface is a blueprint visualization system in an illusion engine and is a finished game script system, height data corresponding to each two-dimensional coordinate data and a plane grid formed by the two-dimensional coordinate data are connected together through the blueprint processing interface, a three-dimensional heat model of the service dimension can be created, and the principle of the method is that a function for constructing the three-dimensional heat model, variables generated in the construction process and events for constructing the three-dimensional heat model are linked, so that the three-dimensional heat model is constructed.

Based on this, the blueprint processing interface comprises a blueprint function library, and in the process of selecting the planar grid and the height data to construct the three-dimensional heat model, functions in the blueprint function library can be called to be directly multiplexed, so that the three-dimensional heat model can be constructed.

Before the three-dimensional heat model is constructed, in one or more embodiments of this embodiment, in order to make the efficiency of constructing the three-dimensional heat model by the blueprint processing interface faster, the index data of each planar grid unit may be determined, so as to reduce the transmission of data volume and speed up the efficiency of constructing the three-dimensional heat model, and a specific implementation manner is as follows:

determining index data of each planar grid cell in the planar grid;

in the case of determining the index data, executing step 108 to select the planar grid and the height data by calling a blueprint processing interface to construct a three-dimensional heat model of the service dimension; correspondingly, the blueprint processing interface determines the planar grid units through the index data, and the three-dimensional heat model is constructed in step 108, specifically, the index data of each planar grid unit and the corresponding height data of each planar grid in the three-dimensional coordinate space are selected through calling a blueprint function contained in the blueprint processing interface to construct the three-dimensional heat model.

Specifically, the index data of each planar grid unit in the planar grid is determined, the blueprint processing interface determines the planar grid unit of each index data through the index data, and when the three-dimensional heat model is constructed, the planar grid unit corresponding to the index data is obtained through the index data, and the three-dimensional heat model is constructed through the height data corresponding to each planar grid unit.

In the process of constructing the three-dimensional heat model, in order to improve the working efficiency of the blueprint processing interface by selecting the plane grids and the height data, corresponding index data is respectively determined for each plane grid in the plane grids, and each index data is unique, so that the data corresponding to each plane grid unit is determined only through the index data, the data quantity selected by the blueprint processing interface is reduced, when the three-dimensional heat model is constructed, the plane grids composed of each plane grid unit can be obtained through the index data, then the three-dimensional heat model is constructed based on the height data, and the construction efficiency of the three-dimensional heat model is improved to a great extent through determining the index data of each plane grid unit.

On the basis of the above construction of the three-dimensional heat model, further, in one or more embodiments of this embodiment, a three-dimensional heat map that can be displayed is obtained by rendering the three-dimensional heat model, and a specific implementation manner is as follows:

Specifically, coordinate height data of a node of each planar grid unit in the three-dimensional coordinate space is determined according to height data of the planar grid unit in the three-dimensional coordinate space; for example, the height data of the planar grid unit is an inclined plane constructed by three-dimensional coordinate points A2, B2, and C2, the value of the z-axis corresponding to the three-dimensional coordinate points A2, B2, and C2 is coordinate height data of the planar grid unit, and a corresponding rendering color is set for the coordinate height data, specifically, a corresponding rendering color is set for the coordinate height data of the node of each planar grid unit, or a corresponding rendering color is set for a plane constructed by a plurality of three-dimensional coordinate points corresponding to a plurality of coordinate height data;

based on this, different rendering colors are set for different coordinate height data, for example, the height data corresponding to the slopes formed by three points A2, B2 and C2 are different from the height data corresponding to the slopes formed by three points A3, B3 and C3, and then the coordinate height data are also different, in the process of setting colors according to the coordinate height data, different colors can be set for the two planes, and a texture map is generated according to the set rendering color coordinate height data and the two-dimensional coordinate data corresponding to the node of each plane grid unit; the texture map is specifically a grid map which is the same as the planar grid, and the rendering color which should be set by each planar grid unit in the texture map is determined based on the height data of each planar grid unit, namely the coordinate height data of the node of each planar grid unit, and the texture map which is obtained at this time can be a texture map which is composed of cubes with rendering colors and has the same area as the planar grid, or can be a texture map which is composed of planar grid units with rendering colors and has the same area as the planar grid;

and adding rendering colors to the three-dimensional heat model through the texture map, and rendering the three-dimensional heat model added with the rendering colors to obtain the three-dimensional heat map of the service dimension.
