Description

Technical Field

[0001] The present invention relates to the field of game technology, and in particular to a method, device, electronic equipment and storage medium for acquiring an edge area of ​​a water body. Background Art

[0002] In water body rendering, it is often necessary to obtain the edge area of ​​the water body, which is usually the boundary area between the water body and the land. The edge area can be used to create the interactive effect of the flowing water body and the shore. In the prior art, the water body and the land model near the water body can be imported into the DCC (Digital Content Creation) software through the function of baking maps in the DCC software. By adjusting the ray step size of AO (Ambient Occlusion), the distance field of the edge boundary between the water body and the land model can be baked out. The edge area of ​​the water body, that is, the boundary area between the water body and the land, is determined according to the distance field. This method requires the model and other resource information to be imported into the DCC software. The operation is very cumbersome and the efficiency of obtaining the edge area is low. In another way, the edge area of ​​the water body can also be drawn by hand-painting, which is also inefficient and affects the subsequent rendering efficiency of the edge area of ​​the water body.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Based on this, the present invention provides a method, device, electronic device and storage medium for obtaining the edge area of ​​a water body, which can be applied to obtaining the edge area of ​​a water body in a virtual scene.

[0022] To facilitate understanding of this embodiment, a method for obtaining a water body edge area disclosed in an embodiment of the present invention is first introduced in detail. The scene model of the virtual scene includes a water body area and a model area adjacent to the water body area. The model area can be one or more models adjacent to the water body area. The model area has a boundary with the water body area, for example, a land model partially blocked by the water surface, a tree model rooted in the water body area and breaking through the water, an island model surrounded by water, etc. Figure 1 As shown, the method includes:

[0023] Step S102: creating a camera assembly on the water surface of the water body area for shooting perpendicular to the water surface; wherein the camera assembly is at a first distance from the water surface of the water body area;

[0024] Specifically, the water body region has water body parameters, such as the boundary range, scaling, position, rotation parameters, etc. of the water surface. According to the water body parameters of the water body region, the camera parameters of the camera component, such as the orthogonal width of the camera component, are determined. According to the orthogonal width of the camera component, the range of the water surface region that the camera component is facing can be determined, and then a suitable size can be set for the rendering target component.

[0025] The rendering target component can be written with the depth information of the model area captured by the camera component. Rendering target components of different sizes have different resolutions. The rendering target component is set to a suitable size to avoid poor device performance due to too high a resolution or unclear images due to too low a resolution.

[0026] At a position located at a first distance above the water surface in the water area, a camera assembly is created perpendicular to the water surface for shooting. The first distance usually refers to the distance between the camera assembly and the water surface in the water area. In practical applications, the height of the water surface can be obtained in advance, the position of the camera assembly can be set above the water surface, and the preset height of the camera assembly can be obtained according to the position; the distance between the camera assembly and the water surface can be obtained by performing a difference operation between the preset height and the height of the water surface.

[0027] It should be noted that by creating the camera component perpendicular to the water surface, it can be ensured that the depth information of the model area captured by the camera component is in a vertical direction and can correspond to the water surface.

[0028] Step S104, controlling the camera assembly to shoot toward the water surface to obtain depth information of the model area captured by the camera assembly;

[0029] Specifically, the water area in the scene model is hidden, the camera component is kept perpendicular to the water surface of the water area, and the camera component is photographed toward the water surface. When the camera component photographs the model area, the depth value of each model position in the model area is captured. The depth value indicates the distance between the model position of the model area and the camera component photographing the scene model.

[0030] Then, the depth value of the model area captured by the camera component is written into the preset rendering target component to obtain a depth map of the model area. The pixel positions in the depth map have a mapping relationship with the model positions of the model area. That is, each pixel position in the depth map of the model area is mapped to a corresponding position in the model area adjacent to the water area in the virtual scene.

[0031] Here, the pixel position can be associated with the depth value of the model position captured by the camera component when shooting the model area, and the depth value corresponding to each pixel position in the depth map of the model area can be obtained, so as to determine the distance between the model position of the model area in the virtual scene and the camera component, and obtain the depth information of the model area.

[0032] In this step, the scene model can be photographed by a camera component to obtain a depth map including the scene model, and the depth information of the model area can be obtained from the depth map.

[0033] Step S106: Generate an initial map based on the first distance and the depth information of the model area; wherein the initial map is used to indicate: a first sub-area in the model area that is above the water surface of the water body area, and a second sub-area that is below the water surface of the water body area;

[0034] Specifically, according to the first distance, a first pixel position whose depth value is less than the first distance can be determined from the depth map of the model area, and the first pixel position constitutes a first pixel area, wherein the area mapped by the first pixel area in the scene model includes a first sub-area, that is, the area in the model area above the water surface of the water body area. A second pixel position whose depth value is greater than the first distance can be determined from the depth map of the model area, and the second pixel position constitutes a second pixel area, wherein the area mapped by the second pixel area in the scene model includes a second sub-area, that is, the area in the model area below the water surface of the water body area.

[0035] Furthermore, the depth values ​​corresponding to each first pixel position and each second pixel position in the depth map of the model area are respectively assigned specified depth values, such as assigning a depth value corresponding to each first pixel position in the depth map to be 1, so that the color of the first pixel position appears white; assigning a depth value corresponding to each second pixel position to be 0, so that the color of the second pixel position appears black; the specified depth value will cause the depth map of the model area to present an effect of only black and white. Here, according to the mapping relationship between the pixel position of the depth map of the model area and the model position of the model area, the first pixel area in the depth map that has a mapping relationship with the first sub-area above the water surface of the water body area is displayed as white, and the second pixel area in the depth map that has a mapping relationship with the second sub-area below the water surface of the water body area is displayed as black. A white boundary outline will appear in the depth map, and an initial map showing a boundary outline is obtained.

[0036] Step S108, blurring the initial map to obtain a target map; wherein the target map includes: an edge region generated by blurring the boundary contour between the first sub-region and the second sub-region.

[0037] The above blurring process can be a Gaussian blurring process on the initial map. After the initial map is Gaussian blurred, the boundary contour between the first sub-region and the second sub-region in the initial map is also blurred, and the blurred boundary region is used as the transition between the first sub-region and the second sub-region. The boundary region is determined as the edge region of the water body, and the transition region between the first sub-region and the second sub-region is softer and more natural. The producer can determine the edge region in the target map as needed to create some effects on the edge region of the water body.

[0038] Step S110: Based on the target map, determine a first sub-region above the water surface of the water region and an edge region of the water region in the scene model.

[0039] Specifically, the pixel position in the first pixel area with the first specified depth value and the position of the edge area in the target map can be determined in the target map; then, based on the mapping relationship, the position of the first sub-area and the position of the edge area of ​​the water area can be determined in the scene model.

[0040] Then, the pre-created water body material code is obtained, and the target texture is mounted on the corresponding position of the water body material according to the first sub-area above the water surface of the water body area and the edge area of ​​the water body area. In actual application, after the target texture is mounted on the water surface, the model area above the water surface, the water body edge area and the water body area in the scene model can be determined according to the target texture, and then the desired effect can be produced for the water body edge area.

[0041] The above-mentioned method for obtaining the edge area of ​​the water body creates a camera component above the water surface of the water body area for shooting perpendicular to the water surface; wherein the camera component is at a first distance from the water surface of the water body area; the camera component is controlled to shoot toward the water surface to obtain depth information of the model area captured by the camera component; an initial map is generated based on the first distance and the depth information of the model area; wherein the initial map is used to indicate: a first sub-area in the model area located above the water surface of the water body area, and a second sub-area located below the water surface of the water body area; the initial map is blurred to obtain a target map; wherein the target map includes: an edge area generated by blurring the boundary contour of the first sub-area and the second sub-area; based on the target map, the first sub-area above the water surface of the water body area and the edge area of ​​the water body area in the scene model are determined. In this method, there is no need to import the model resources into external software. The initial map for indicating the first sub-area above the water surface of the water body area in the model area and the second sub-area below the water surface of the water body area can be directly generated in real time according to the first distance between the camera component and the water surface and the depth information of the model area adjacent to the water body area. By blurring the initial map, the boundary contour between the first sub-area and the second sub-area in the initial map is converted into a blurred boundary area, and a target map with a transition edge area is obtained, and then the edge area with the transition is used as the water body edge area. This method is simple and convenient to obtain the edge area of ​​the water surface as the water body edge area, which is conducive to improving the rendering efficiency of the water body edge area.

[0042] In one approach, you can create a camera component above the water surface in a water area by:

[0043] Obtain parameter information of a water body area; based on the parameter information, determine camera parameters of a camera component; wherein the camera parameters include: an orthogonal width of the camera component; based on the orthogonal width in the camera parameters, determine a preset size of a rendering target component; wherein the rendering target component is used to write depth information of a model area captured by the camera component; based on the camera parameters, create a camera component perpendicular to the water surface of the water body area at a first distance above the water surface of the water body area for shooting.

[0044] The parameter information of the water area may be the boundary range of the water surface, the scaling ratio of the water surface, the position of the water surface, the rotation parameters of the water surface, etc., which are set when the water area is created in the virtual scene. The camera parameters of the camera component for shooting the scene model are determined by these parameter information, and the camera parameters include the orthogonal width of the camera. That is, according to these parameter information, a suitable orthogonal width can be set for the camera component to ensure that the camera component shoots the water surface within the boundary range of the water surface and captures the depth information of the model area adjacent to the water area.

[0045] According to the orthogonal width of the camera component, the size of the water surface area that the camera component is facing can be determined, and then the appropriate size can be set for the rendering target component, for example, the size of the rendering target component RenderTerget can be set according to the orthogonal width. The rendering target component can be understood as a blank map with information written into it. When the camera component captures the depth information of the model area, it is written into the rendering target component. Here, the appropriate size is set for the rendering target component to avoid the device performance being reduced due to too high resolution, or the image clarity being reduced due to too low resolution.

[0046] Then, according to the position of the camera parameter at a first distance above the water surface of the water body area, a camera component is created perpendicular to the water surface for shooting. For example, the height of the water surface is obtained in advance, the position of the camera component is set above the water surface, and the preset height of the camera component is obtained according to the position. Then, the difference between the preset height and the height of the water surface is calculated, and the distance between the camera component and the water surface of the water body area is obtained as the first distance.

[0047] The following embodiments provide specific implementation methods for obtaining depth information of a model area.

[0048] Specifically, the water area in the scene model is hidden, and the camera component is controlled to shoot toward the water surface; when the camera component shoots the model area, the depth value of the model position captured by the camera component is obtained; wherein the depth value is used to indicate the depth information of the model position of the model area; the depth value of the model area captured by the camera component is written into the rendering target component to obtain a depth map of the model area; wherein the pixel position of the depth map of the model area has a mapping relationship with the model position of the model area, and the pixel position is associated with the depth value of the model position captured by the camera component when shooting the model area; from the depth map of the model area, the depth information of the model area is obtained.

[0049] Here, the parameters of the camera component are maintained unchanged, the water area in the scene model is hidden, the camera component is kept perpendicular to the water surface of the water area, and the camera component is shot toward the water surface. When the camera component shoots the model area, the depth value captured by the camera component for the model position of the model area is obtained. The depth value indicates the distance between the model position of the model area and the camera component that shoots the scene model.

[0050] Then, the depth value of the model area captured by the camera component is written into the rendering target component to obtain a depth map of the model area; the pixel position in the depth map has a mapping relationship with the model position of the model area. That is to say, each pixel position in the depth map of the model area will be mapped to the corresponding position in the model area adjacent to the water area in the virtual scene. Here, the pixel position can be associated with the depth value of the model position captured by the camera component shooting the model area, and the depth value corresponding to each pixel position in the depth map of the model area can be obtained, thereby determining the distance between the model position of the model area in the virtual scene and the camera component, and obtaining the depth information of the model area.

[0051] The following embodiments provide a specific implementation method for generating an initial map.

[0052] Specifically, a depth map of the model area is obtained; based on a first distance, a first pixel area located above the water surface of the water body area and a second pixel area located below the water surface of the water body area in the depth map of the model area are determined; wherein the area in which the first pixel area is mapped in the model area includes a first sub-area; the area in which the second pixel area is mapped in the model area includes a second sub-area; and an initial map is generated based on the first pixel area and the second pixel area.

[0053] Here, a depth map of the model area photographed by the camera assembly perpendicular to the water surface of the water body area can be obtained, and a first pixel area located above the water surface of the water body area and a second pixel area located below the water surface of the water body area can be determined from the depth map of the model area according to the first distance. The area mapped in the model area by the first pixel area includes a first sub-area, and the area mapped in the model area by the second pixel area includes a second sub-area. Then, based on the first pixel area and the second pixel area, an initial map for indicating the first sub-area and the second sub-area is generated.

[0054] Specifically, a first pixel position whose depth value in the depth map of the model area is less than a first pixel position of a first distance is obtained, and the first pixel position constitutes a first pixel area; a second pixel position whose depth value in the depth map of the model area is greater than the first distance is obtained, and the second pixel position constitutes a second pixel area.

[0055] It can be understood that if the depth value of the pixel position in the depth map of the model area is equal to the first distance, it means that the model position mapped by the pixel position in the model area is located on the water surface of the water body area. Taking the water surface as the reference, if the depth value of a certain pixel position in the depth map of the model area is less than the first distance, it means that the model position mapped by the pixel position in the model area is located above the water surface of the water body area, and the pixel position is determined as the first pixel position; if the depth value of a certain pixel position in the depth map of the model area is greater than the first distance, it means that the model position mapped by the pixel position in the model area is located below the water surface of the water body area, and the pixel position is determined as the second pixel position. In this way, by traversing each pixel position in the depth map of the model area, multiple first pixel positions and multiple second pixel positions can be determined, and the pixel area composed of the first pixel position is determined as the first pixel area, and the pixel area composed of the second pixel position is determined as the second pixel area. Correspondingly, the area mapped by the first pixel area in the scene model includes the first sub-area, and the area mapped by the second pixel area in the scene model includes the second sub-area.

[0056] Furthermore, according to the first pixel region and the second pixel region, the process of generating the initial map is as follows:

[0057] Based on the first pixel region and the second pixel region, a binarization process is performed on the depth map of the model region to obtain an initial map showing a boundary contour of the first sub-region and the second sub-region.

[0058] Specifically, the depth values ​​of the pixel positions in the first pixel area in the depth map of the model area are set to the first specified depth values, and the depth values ​​of the pixel positions in the second pixel area are set to the second specified depth values, to obtain an initial map showing the boundary outline of the first sub-area and the second sub-area.

[0059] The above-mentioned first specified depth value and second specified depth value can be 0 or 1, and the first specified depth value and the second specified depth value are different. The setting of the specified depth value will cause the depth image to present only black and white effects. For example, the depth value corresponding to each first pixel position in the depth map is assigned a value of 1, so that the color of the first pixel position is white; the depth value corresponding to each second pixel position is assigned a value of 0, so that the color of the second pixel position is black; here, according to the mapping relationship between the pixel position of the depth map and the model position of the scene model, the first pixel area in the depth map of the model area that has a mapping relationship with the first sub-area above the water surface of the water body area will be displayed as white, and the second pixel area that has a mapping relationship with the second sub-area below the water surface of the water body area will be displayed as black, and the white boundary outline of the first sub-area and the second sub-area will be displayed in the depth map of the model area, and the depth map showing the white boundary outline will be used as the initial map.

[0060] Furthermore, the initial map is subjected to Gaussian blur processing to obtain a target map having a gradient effect in the edge area.

[0061] The entire initial map can be processed through Gaussian blur processing. Since the initial map only has black, white, and the boundary between black and white, after Gaussian blur processing on the initial map, black is still black, white is still white, but the boundary becomes wider, becoming a gradient area from black to white.

[0062] Here, after the initial map is Gaussian blurred, the boundary contour between the first sub-region and the second sub-region in the initial map is also blurred to obtain a blurred boundary region, which can be regarded as the edge region of the water body.

[0063] For example, the initial map includes a first pixel region displayed in white and a second pixel region displayed in black, and the initial map is obtained by displaying a white boundary outline of the first sub-region and the second sub-region. After blurring the initial map, the following is obtained: Figure 2 The blurred boundary area presents a gradient effect from white to gray and then to black. This boundary area is used as the edge area of ​​the water body, and the transition area between white and black is softer and more natural.

[0064] Using the target map as a mask, the producer can choose not to display certain areas in the target map, or display certain areas in the target map as the required effect, so as to facilitate the subsequent rendering of the edge area of ​​the water body. For example, the edge area in the target map is used as the boundary area between the water surface and the land, so as to render the boundary area between the water surface and the land to obtain the interactive effect of flowing water and the shore.

[0065] Furthermore, based on the target map and the mapping relationship, the first sub-area above the water surface of the water area and the edge area of ​​the water area in the scene model are determined; based on the first sub-area above the water surface of the water area and the edge area of ​​the water area, the target map is mounted on a preset water material corresponding to the water area.

[0066] Specifically, after obtaining the target map, the pixel position in the first pixel area with the first specified depth value and the position of the edge area in the target map can be determined in the target map; then, based on the mapping relationship, the position of the first sub-area and the position of the edge area of ​​the water area can be determined in the scene model.

[0067] Then, the pre-created water body material code is obtained, and the target texture is mounted on the corresponding position of the water body material according to the first sub-area above the water surface of the water body area and the edge area of ​​the water body area. Figure 2 Take the target map shown as an example, and use the Lerp interpolation function to input the target map into the program. The Lerp interpolation function is used to perform linear interpolation between two parameters, such as linear interpolation between 0 and 1. For the area with a value of 0 in the target map, the water material is displayed, and the area with a value of 1 is displayed white. This ensures that only the edge effect is produced for the edge area, and does not affect the normal display of other content in the scene model.

[0068] In practical applications, after the target map is mounted on the water surface, the model area above the water surface, the edge area of ​​the water body, and the water body area in the scene model can be determined according to the target map, and then the desired effect can be produced for the edge area of ​​the water body. For example, based on the target map, the depth value of the pixel position in the target map is obtained, and the information of the scene model is determined according to the depth value. For example, the area in the target map with a value of 1 and a white color can be the shore above the sea surface, the area with a value of 0 and a black color can be the deep sea below the sea surface, and the area with a gradient effect between 1 and 0 can be the slope between the shore and the deep sea. After extracting the information about the shore, the deep sea, and the slope between the shore and the deep sea, the information can be used to produce the desired effect.

[0069] In the related art, by obtaining the first distance of the water body area and the depth information of the model area adjacent to the water body area, the distance between the position point under the water surface of the water body area in the model area and the water surface is obtained by calculating the depth difference, and the position point is rendered according to the distance between the position point and the water surface to generate the rendered water body edge area. For example, Figure 3As shown in the figure, the underwater position points closer to the water surface are rendered white, and the underwater position points farther from the water surface are rendered black, and the edge area of ​​the water body is rendered. However, depth is not a boundary after all. Since depth extends along the Z axis, it is greatly affected by the change of line of sight. It is fine when the line of sight is opposite to it, but once it is tangent, it will be exposed. Figure 4 As shown in the figure, when the columnar object is inserted vertically into the horizontal plane, the white edge area that should be rendered around the column is rendered below the columnar body, resulting in artifacts. In addition, for water areas, only translucent materials support depth acquisition. Some stylized water surfaces do not require translucent materials. Forcibly turning on translucent materials to obtain depth is not worth the effort.

[0070] In the present application, a depth map can be obtained by photographing a scene model through a camera component.
