[0056] S102, obtaining a configuration file of each weather element in a weather element set corresponding to each weather type; wherein the configuration file includes attribute information of each weather element.

[0057] For example, the attribute information of the sky includes parameters required by the display device that are calculated in real time based on longitude and latitude, altitude, weather type and precise time; among them, longitude and latitude are the unique coordinates of every location on the earth, and the longitude and latitude of a specific location can be obtained through GPS (Global Positioning System) equipment, map API (Application Programming Interface) or GIS (Geographic Information System). For example, on many smart phones and tablets, the built-in GPS device can be used to obtain the current longitude and latitude. In addition, many online map services also provide API interfaces, through which the longitude and latitude of any location can be obtained; altitude is the height of a point on the ground relative to the sea level, and the altitude information of a specific location can be obtained through online map services or special altitude query websites, or special equipment can be used to measure the altitude;

[0058] The attribute information of the light source includes the color of the light source (such as red, green, blue, etc.), luminous intensity (the intensity of the light), three-dimensional spatial position (the location of the light source), attenuation function (the way the intensity of the light gradually decreases with increasing distance), etc.

[0059] The attribute information of thin clouds and cloud layers includes the cyclic disturbance of clouds, the edge dissipation of clouds and the dissolution and dissipation of clouds, including the front normal map, the back normal map, the depth map, the internal glow map, the three-dimensional position in space, the mask relationship (the occlusion effect of clouds), the drift parameter (the moving speed and direction of clouds), the disturbance parameter (the shape change of clouds), the overall opacity, the local opacity (the opacity of clouds), the local normal reduction parameter (the shape change of clouds), etc.

[0060] The sun's attribute information includes sunlight, light spots, halos, rays, etc., and their corresponding three-dimensional spatial positions;

[0061] The attribute information of raindrop special effects includes special effect ID (an identifier for identifying raindrops), density (how dense the raindrops are), falling speed (how fast the raindrops fall), number of superposition layers (the number of raindrops), depth of field position (the position of the raindrops in the depth of field), three-dimensional space position (the position of the raindrops in the scene), etc.

[0062] The attribute information of the snowflake special effect includes parameters such as special effect ID, density, falling speed, lateral drifting speed (lateral speed of snowflakes drifting in the air), number of superposition layers, depth of field position, and three-dimensional space position;

[0063] The attribute information of the haze effect includes the effect ID and other possible parameters, such as the density and color of the haze.

[0064] The attribute information of the sand-raising effect includes the effect ID and other possible parameters, such as the particle size and color of the sand.

[0065] The attribute information of the dust effect includes the effect ID and other possible parameters, such as the particle size and color of the dust.

[0066] The attribute information of the dust storm special effect includes the special effect ID and other possible parameters, such as the intensity and color of the dust storm.

[0067] In this step, the configuration file can be updated in a variety of ways, such as being distributed through a network or storage medium, so that weather types can be added, rendering effects can be modified, etc. without changing the rendering framework, thereby greatly improving scalability and maintainability while reducing design costs.

[0068] S103, performing weather rendering on the sky layout according to the weather element set corresponding to each weather type and the attribute information of each weather element in the weather element set to obtain a three-dimensional weather model.

[0069] Create a sky layout, put each weather type into the sky layout, separate them with three-dimensional positions, call the configuration files of each weather element set corresponding to each weather type, use the Open GL (Open Graphics Library) library for rendering, and convert the data in the configuration file into an actual three-dimensional weather model to achieve highly realistic rendering effects.

[0070] In actual applications, the weather conditions around the user can be identified, the corresponding three-dimensional weather model can be selected, and the previous weather effects can be switched.

[0071] Therefore, the present invention expresses the attribute information of each weather element in the form of a configuration file in three-dimensional space through a design tool, and completes the data-driven rendering in the configuration file through a rendering engine to achieve a highly restored three-dimensional weather rendering effect. This data-driven approach allows users to freely adjust the attribute information of various weather elements in weather phenomena to meet personalized needs, greatly improving design and development efficiency.

[0072] In order to further improve the effect of restoring three-dimensional weather rendering, the following attributes can be added to each weather type in the sky layout: coordinate information of the sky layout and lens parameters corresponding to each weather type. The implementation process of the above step S103 is as follows: obtain the coordinate information of the sky layout and the lens parameters corresponding to each weather type, and then perform weather rendering on the sky layout based on the coordinate information and lens parameters corresponding to each weather type, the weather element set and the attribute information of each weather element in the weather element set to obtain a three-dimensional weather model.

[0073] In this embodiment, the coordinate information of the sky layout: can define the position coordinates (x, y, z) of the sky layout in three-dimensional space. By setting the position coordinates of the sky layout, it can be placed in different positions, thereby changing the display effect of different weather types in the scene.

[0074] Lens parameters corresponding to weather types: You can define the lens parameters used for each weather type, including lens coordinates and FOV (Field of View). The lens coordinates determine the observation position and direction of the weather type, and you can adjust the coordinates to achieve the observation effect of different weather types. FOV refers to the field of view, which determines the size of the range that can be seen when observing the weather type. By adjusting the FOV, you can control the display effect of the scene, such as enlarging or reducing the display range of a specific weather type.

[0075] These properties can be used to control the display effects of different weather types in the scene and achieve more realistic sky rendering. In the implementation process, you can use a 3D graphics library or engine to process these properties and use the API interfaces they provide to set and render the sky layout and various weather types.

[0076] The following is an introduction to the cloud layer's attribute information.

[0077] The cloud attributes include: cloud cyclic disturbance, cloud edge dissipation, and cloud dissolution. Different weather effects can be displayed by identifying the weather conditions around the user.

[0078] in, Figure 2 The present invention is a flowchart of determining the cyclic disturbance of clouds according to an embodiment of the present invention.

[0079] like Figure 2 As shown, the process of determining the cyclic disturbance of clouds disclosed in the present invention includes:

[0080] S201, based on a first set slowing-down coefficient k1, adjusting the current time stamp uTime to obtain a first slowing-down time time1.

[0081] Among them, the first slowing down time time1=uTime*k1: this is the method to set the current time in the simulation, where k1 is a slowing down coefficient that can control the speed of time.

[0082] S202: Based on the second set slowing-down coefficient k2, the current time stamp uTime is adjusted to obtain a second slowing-down time time2.

[0083] The second slowing down time time2=uTime*k2; k2 is also a slowing down coefficient, which can be adjusted according to the demand to control the speed of time.

[0084] S203, obtaining a target coordinate vector nuv of the current pixel of the cloud; wherein the target coordinate vector nuv is obtained by adjusting the original coordinate vector uv of the current pixel of the cloud based on the set scaling vector k3.

[0085] Among them, nuv=uv*k3; this is used to scale the original coordinate vector of the current pixel of the cloud. By adjusting the scaling vector k3, the size of the cloud can be changed.

[0086] S204 , generating disturbance noise n based on the first slowing down time time1 , the second slowing down time time2 and the target coordinate vector nuv.

[0087] A three-dimensional FBM (fractional Brownian motion) algorithm is used to calculate the disturbance noise n with the first slowing down time time1, the second slowing down time time2 and the target coordinate vector nuv as parameters; this is a common operation in geographic information systems (GIS) or similar fields, where the FBM algorithm is often used to generate random, continuous noise data to simulate natural phenomena.

[0088] S205, based on the disturbance noise n, the original coordinate vector uv is disturbed to obtain the cyclic disturbance of the cloud.

[0089] Use the Open GL Shader Language standard function smoothstep to remap n to the range of 0 to 1 to make the noise curve steeper, denoted as m, where the standard function smoothstep is used to achieve a smooth transition effect.

[0090] In the shader program, when using the standard function texture to obtain the front normal, back normal, internal light transmittance and opacity of the cloud, replace the commonly used function texture(uv) with the function texture(uv+m), where uv is the original coordinate vector. This is used to obtain the material data after the current pixel coordinates are offset by a certain distance in the two-dimensional plane according to the noise when obtaining the map pixel. This step is used to offset the pixel coordinates of the map according to the disturbance caused by the noise, thereby changing the location where the material data is obtained.

[0091] The acquired material data is synthesized so that all rendered cloud image data can be combined into a final image or scene.

[0092] Figure 3 The present invention is a flowchart of determining the edge dissipation of a cloud according to an embodiment of the present invention.

[0093] like Figure 3 As shown, the process of determining the edge dissipation of a cloud in the present disclosure includes:

[0094] S301, adjusting the current timestamp based on a first set slowing-down coefficient to obtain a first slowing-down time time1.

[0095] S302: Based on a second set slowing-down coefficient, adjust the current timestamp to obtain a second slowing-down time time2.

[0096] S303, obtaining a target coordinate vector nuv of the current pixel of the cloud; wherein the target coordinate vector nuv is obtained by adjusting the original coordinate vector uv of the current pixel of the cloud based on the set scaling vector.

[0097] S304: Generate disturbance noise n based on the first slowing down time time1, the second slowing down time time2 and the target coordinate vector nuv.

[0098] It should be noted that the implementation process of steps S301-S304 is detailed in the above-mentioned contents of steps S201-S204, and will not be described in detail here.

[0099] S305, obtaining depth information d and opacity alpha corresponding to the current pixel of the cloud.

[0100] For example, the standard function texture can be used in the shader program to obtain the depth information of the cloud at the current pixel, recorded as d, that is, to obtain the depth information of the current pixel in the three-dimensional space.

[0101] In the shader program, use the standard texture function to get the alpha value of the cloud at the current pixel.

[0102] S306: Determine the boundary edge of the cloud according to the start edge boundary value startEdge and the end edge boundary value endEdge of the cloud and the depth information d.

[0103] Use the standard function shader and the appropriate start edge limit value startEdge and end edge limit value endEdge, call smoothstep(endEdge, startEdge, d), and the result is used as the boundary edge of the cloud. The boundary edge of the cloud is used as a parameter to determine whether the current pixel belongs to the edge pixel of the cloud.

[0104] S307 , adjusting the opacity alpha of the current pixel of the cloud according to the cloud boundary edge and the disturbance noise n.

[0105] The opacity alpha of the current pixel is calculated according to the formula alpha'=alpha-edge*edge-edge*n*0.8 to obtain the adjusted opacity alpha', so that the edge disappears naturally.

[0106] S308, determining whether the edge of the cloud disappears according to the adjusted opacity alpha' corresponding to each pixel in the cloud.

[0107] Use alpha' as the opacity of the current pixel in subsequent rendering calculations to determine the edge dissipation of the cloud.

[0108] The cloud edge dissipation disclosed in the present invention simulates the cloud edge dissipation effect by operating at the pixel level and utilizing depth information and noise. This method can produce a very natural and realistic effect.

[0109] Figure 4 The present invention is a flowchart of determining the dissolution and dissipation of clouds according to an embodiment of the present invention.

[0110] It should be noted that the dissolution and dissipation of clouds is based on the dissipation of the edges of the clouds.

[0111] like Figure 4 As shown, the process of determining the dissolution and dissipation of clouds disclosed herein comprises:

[0112] S401, adjusting the starting edge limit value startEdge of the cloud.

[0113] S402, determining the edge boundary value interval (startEdge, 1) according to the adjusted start edge boundary value startEdge'.

[0114] S403, mapping the end edge boundary value endEdge of the cloud to the edge boundary value interval according to the animation driving coefficient p, to obtain an updated end edge boundary value endEdge'.

[0115] S404: Determine the dissolution of the cloud according to the adjusted start edge boundary value startEdge' and the updated end edge boundary value endEdge'.

[0116] In this embodiment, startEdge is adjusted, and endEdge is mapped to the interval of (startEdge, 1) according to the animation driving parameter p. By adjusting the values ​​of startEdge and endEdge, the dissolution effect of the cloud can be controlled. The animation driving parameter p can be dynamically adjusted according to time or other animation control parameters. Mapping endEdge to the interval of (startEdge, 1) can ensure that the cloud gradually disappears from sight during the dissipation process.

[0117] The present invention realizes the dissolution and dissipation of clouds by adjusting edge judgment parameters and animation driving parameters to simulate the formation and dissipation process of clouds. This method combines pixel-level operations and depth information, and uses noise to enhance the natural effect. In this way, by adjusting the driving parameters, the dissipation and dissolution effect of clouds can be rendered. This effect is used for the process of cloud appearance and disappearance, and can very well simulate the natural effect of water vapor gathering in the atmosphere to form clouds and being blown away and disappearing by the wind.

[0118] In summary, according to the weather rendering method of the embodiment of the present disclosure, a weather element set corresponding to each weather type in a plurality of weather types is first obtained, wherein the weather type is obtained by dividing the real weather phenomenon, and a configuration file of each weather element in the weather element set corresponding to each weather type is obtained, wherein the configuration file includes the attribute information of each weather element, and then weather rendering is performed on the sky layout according to the weather element set corresponding to each weather type and the attribute information of each weather element in the weather element set to obtain a three-dimensional weather model. Therefore, the present disclosure expresses the attribute information of each weather element in the sky layout in the form of a configuration file, and completes the data-driven rendering in the configuration file through a rendering engine to achieve a highly restored three-dimensional weather rendering effect. This data-driven method allows users to freely adjust the attribute information of various weather elements that make up the weather phenomenon, and can modify the weather type to meet personalized needs, thereby greatly improving design and development efficiency.
