Description

[0001] The present application relates to the field of virtual three-dimensional scenes, and in particular to a method for rendering waves in a virtual scene, a storage medium, and an electronic device. Background Art

[0002] In a virtual 3D scene, in order to improve the details of the lake surface, it is hoped that waves from the lake to the shore can be added at the junction of the lake surface and the shore. To meet this demand, the more common approach is to use the distance field method or the depth of the terrain under the lake surface to obtain the gradient area from the lake to the shore and then add waves.

[0003] However, if you want to use the distance field method, the mobile terminal does not support it. If you want to use the depth of the terrain under the lake to obtain the gradient area from the lake to the shore and then add waves, the gradient area calculated using the depth will change with the change of the perspective, which is not suitable for virtual scenes with free perspectives. In addition, the wave effect obtained using this method often lacks details and is more cartoon-like, which does not match the realistic style, resulting in a poor display effect of the waves.

[0023] In order to solve the technical problem of poor display effect of virtual waves in mobile virtual scenes in the prior art, the present application provides a method for rendering waves in a virtual scene, which can achieve the purpose of improving the display effect of virtual waves.

[0024] Figure 1 The present invention provides a flowchart of a method for rendering waves in a virtual scene. Figure 1 As shown, the rendering method of the waves in the above virtual scene includes:

[0025] S102, obtaining a first normalization result and a second normalization result, wherein the first normalization result is a normalized result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the terrain model intersecting with the water surface model, and the second normalization result is a normalized result of the distance from each point on the intersection line of the water surface model and the terrain model to a standard point on the intersection line, where the standard point is a point determined on the intersection line;

[0026] S104, determining the texture mapping coordinates of the water surface model according to the first normalization result and the second normalization result;

[0027] S106, mapping the wave spray map to the texture map coordinates and controlling the wave spray map to scroll within a certain range.

[0028] The virtual three-dimensional scene in this embodiment includes at least a water surface model and a terrain model. The terrain model may be a shore (or may include part of the land below the water surface or only the shore), and the water surface model is part of the water surface. Figure 2 It is an exemplary top view of the shore and water surface of a certain area, wherein part 202 is the shore, part 204 is the water surface, and the two intersect at an intersection line. Figure 3 is a schematic cross-sectional view (side view) of the two, wherein the shore portion 302 and the water surface model portion 304 intersect. In this embodiment, when performing data calculation, the horizontal surface portion 306 of the terrain model 302 and the horizontal surface portion 306 of the water surface model can be used for calculation to determine the wave map, without calculating the underground and underwater parts. The terrain model and water surface model mentioned in the text refer to Figure 3 The horizontal plane portion 306 in the.

[0029] The first normalized result is the normalized result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the intersection line where the water surface model and the terrain model intersect. The intersection of the water surface model and the terrain model on the horizontal plane forms a curve, which can be called the intersection line. Each vertex on the water surface model can be a vertex on the horizontal plane of the water surface model, or all vertices on the horizontal plane and the part below the horizontal plane. Calculate the distance from the vertex to the intersection line, normalize the distance, and obtain the first normalized result.

[0030] The above second normalization result is to select a point on the above intersection line as a standard point, the standard point is randomly selected, and then calculate the distance from each point on the intersection line to the standard point, and normalize the distance to obtain the second normalization result.

[0031] According to the first normalization result and the second normalization result, the texture map coordinates of the water surface model can be determined. The texture map coordinates are used to mark the position of the texture map, that is, where on the water surface model the texture map of the water surface model is pasted.

[0032] After the texture coordinates are determined, the wave map can be mapped to the texture coordinates. In addition, the wave map can be controlled to scroll within a certain range to achieve the effect of lake waves.

[0033] This embodiment obtains a first normalization result and a second normalization result, wherein the first normalization result is a normalized result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the terrain model intersecting with the water surface model, and the second normalization result is a normalized result of the distance from each point on the intersection line of the water surface model and the terrain model to a standard point on the intersection line, and the standard point is a point determined from the intersection line; determines the texture map coordinates of the water surface model according to the first normalization result and the second normalization result; and maps a wave map to the texture map coordinates and controls the wave map to scroll within a certain range. When displaying virtual waves, the texture map coordinates of the water surface model can be determined through the water surface model and the terrain model, and the wave map is mapped on the texture map coordinates, and the wave map is controlled to scroll within a certain range, thereby ensuring that the direction of the wave map is fixed and the effect of scrolling within a certain range is achieved, realizing the simulation of the waves, and solving the problem of poor display effect of the waves in the prior art.

[0034] As an optional example, obtaining the first normalized result includes: obtaining the distance from each vertex on the water surface model to the terrain model; and performing a normalization operation on the distance to obtain the first normalized result.

[0035] In this embodiment, the water surface model is a model surrounded by multiple model vertices. For the vertex on the horizontal plane, the distance from the vertex to the terrain model is calculated, and the distance is the minimum distance from the vertex to the terrain model. After calculating the distance, each vertex corresponds to a distance, and the distance is normalized to obtain a first normalized result. Normalizing the distance can be multiplying the distance by a coefficient to normalize the distance to a number between 0 and 1.

[0036] As an optional example, obtaining the distance from each vertex on the water surface model to the terrain model includes: obtaining the first coordinate of each vertex on the water surface model in the virtual three-dimensional scene; drawing a perpendicular line from the first coordinate to each face of the terrain model; and determining the smallest perpendicular line as the distance from the first coordinate to the first coordinate to the terrain model.

[0037] In this embodiment, when calculating the distance from each vertex on the water surface model to the terrain model, each vertex on the water surface model is used as the current vertex, and then a perpendicular line is drawn from the current vertex to the surface of the terrain model. There may be multiple perpendicular lines, and the perpendicular line with the shortest distance is selected from them, and the length of the perpendicular line is used as the distance from the current vertex to the terrain model.

[0038] For example, Figure 4 As shown, Figure 4 Point 402 is a vertex on the water surface model (the actual number and density of vertices are not limited and depend on the actual situation). Taking vertex 402 as an example, a perpendicular line is drawn from the vertex to the terrain model 202, and the shortest perpendicular line is the distance from the vertex to the terrain model.

[0039] As an optional example, obtaining the second normalized result includes: randomly determining a point on the intersection line as a standard point; obtaining the distance from each point on the intersection line to the standard point; and comparing each distance with the maximum distance among the distances to obtain the second normalized result.

[0040] In this embodiment, when calculating the second normalization result, after randomly determining a point on the intersection line as a standard point, the distances from other points on the intersection line to the standard point can be determined. Figure 5 As shown, Figure 5 In the example, if the vertex 502 on the intersection line is a standard point, the distances from other vertices on the intersection line, such as the vertex 504 to the standard point 502, are calculated, thereby obtaining the distances from each vertex on the intersection line to the standard point.

[0041] After calculating the distance from each point to the standard point, select the largest distance as the denominator and each distance as the numerator to calculate multiple numbers between 0 and 1, which are the second normalization results.

[0042] As an optional example, determining the texture mapping coordinates of the water surface model based on the first normalization result and the second normalization result includes: creating new texture mapping coordinates, where the texture mapping coordinates are a two-dimensional vector; using the first normalization result as the y channel in the texture mapping coordinates; and using the second normalization result as the x channel in the texture mapping coordinates.

[0043] In this embodiment, after obtaining the first normalization result and the second normalization result, a two-dimensional vector can be established as the texture mapping coordinate. The two-dimensional vector includes two channels, namely the x channel and the y channel, which represent the x-axis and y-axis values ​​of the texture mapping coordinate in the virtual three-dimensional scene. The above-mentioned first normalization result and the second normalization result are used as the values ​​of the x channel and the y channel in the two-dimensional vector. Specifically, the first normalization result is used as the value of the y channel, which represents the value of the y channel formed by the normalized result of the distance from the point on the water surface model to the intersection line, and the value of the x channel is the second normalization result, which represents the value of the x channel formed by the normalized result of the distance from the point on the intersection line to the standard point.

[0044] The above texture mapping coordinates are UV coordinates, which means that all image files are a two-dimensional plane. The horizontal direction is U and the vertical direction is V. Through this plane, the two-dimensional UV coordinate system can locate any pixel on the image. Create a new texture mapping coordinate, that is, create a UV coordinate with an empty value, the horizontal direction is the x channel, and the vertical direction is the y channel. Then, fill the value of the first normalization result and the value of the second normalization result into the texture mapping coordinate. For example (the following values ​​and quantities are only for example), the first normalization result is: 0.1, 0.3, 0.1, 0.2, 0.5, 0.6, 0.5, 0.2, and the second normalization result is 0.6, 0.3, 0.4, 0.6, 0.6, 0.5, 0.8, 0.5, then, you get the coordinate pairs of multiple pixel points: (0.1, 0.6), (0.3, 0.3), (0.1, 0.4), ... (0.2, 0.5).

[0045] As an optional example, mapping the spray map to the texture mapping coordinates includes: sampling the value on the y channel of the spray map to the y channel of the texture mapping coordinates, and sampling the value on the x channel of the spray map to the x channel of the texture mapping coordinates.

[0046] In this embodiment, after the texture mapping coordinates are determined, the spray map can be mapped to the texture mapping coordinates, specifically, the value on the y channel of the spray map is sampled to the y channel of the texture mapping coordinates, and the value on the x channel of the spray map is sampled to the x channel of the texture mapping coordinates. Since the y channel on the texture mapping coordinates is the first normalized result, and the x channel on the texture mapping coordinates is the second normalized result, and the first normalized result is the normalized result of the distance from the point on the water surface model to the terrain model, and the second normalized result is the normalized result from the point on the intersection line to the standard point, therefore, after the spray map is sampled to the texture mapping coordinates, the position and orientation of the spray map are consistent with the orientation of the water surface model.

[0047] For example, continuing with the above example, after the texture mapping coordinates are determined, the texture mapping coordinates contain a series of pixel coordinate pairs, such as (0.1, 0.6), (0.3, 0.3), (0.1, 0.4), ... (0.2, 0.5) in the above examples. According to the coordinates of each pixel point, the pixel point at the corresponding position is sampled from the wave map and sampled into the texture mapping coordinates, thereby saving a series of pixel points in the wave map in the texture mapping coordinates.

[0048] As an optional example, controlling the wave map to scroll within a certain range includes: obtaining a preset target interval; when controlling the wave map to scroll, determining that the maximum coordinate value in the wave map is less than the right endpoint of the target interval, and determining that the minimum coordinate value in the wave map is greater than the left endpoint of the target interval.

[0049] In this embodiment, when controlling the wave map to scroll within a certain range, a target interval needs to be determined, and the target interval is the scrolling range of the wave map. The target interval can be the interval of the coordinates corresponding to the y channel, and the coordinates corresponding to the x channel remain unchanged. That is, the wave map is controlled to scroll within a range away from or close to the shore, rather than horizontally scrolling flush with the shore.

[0050] In this embodiment, when controlling the wave map to scroll within a certain range, the coordinates corresponding to the y channel can be enlarged or reduced according to a certain ratio. For example, the coordinates of the y channels in the above examples (0.1, 0.6), (0.3, 0.3), (0.1, 0.4), ... (0.2, 0.5) are enlarged or reduced, and the original x channel coordinates remain unchanged. After the y channel coordinates change, the pixels sampled from the wave map will also change. For example, for a certain pixel point originally sampled, after the y channel coordinates change, the pixel point above or below the original pixel point is sampled. By expanding or reducing the coordinates of the y channel as a whole, the pixel points above or below the original pixel point are batch sampled to form a wave effect.

[0051] For example, after transforming the y channel coordinates of the pixel points of the wave crest of the originally collected wave map, the pixel points of the wave tail of the collected wave map can be transformed by transforming the y channel coordinates, thereby achieving the effect of successively collecting different wave positions of the wave map. In terms of external performance, it shows the effect of the waves moving within a certain range.

[0052] Figure 6 It is a system flow chart of this embodiment.

[0053] First, obtain all water surface models and terrain models that intersect with the water surface. When calculating, use the data of the horizontal plane, and do not use the data on the ground and below the horizontal plane. For the water surface model, traverse the lake surface model and perform the following operations on it: calculate the distance from each vertex on the water surface model to the terrain model, normalize the distance according to a distance range parameter, obtain the first normalized result, and store it in the vertex color of the model; calculate a second normalized result according to the boundary between the water surface and the shore; use the above normalized results to calculate a new set of texture mapping coordinates uv for the water surface model, specifically use the first normalized result as the y channel and the second normalized result as the x channel. Then perform the following calculations on the material: map the wave map (foam map) to the newly generated uv above, that is, use the x and y channels of uv to sample the foam map, and control the map to scroll at a certain speed; use the normalized distance, multiplied by a range parameter as the range of the wave to prevent the wave from moving beyond the range. Finally, save the model and material.

[0054] In this embodiment, information such as the distance field is baked into the water surface model itself. In this way, there is enough data information to generate detailed waves, and there is no need to store the distance field of the entire scene. The consumption is low and there is no problem in applying it to mobile terminals. At the same time, since the information of the model itself is used, it is irrelevant to the line of sight and the terrain under the lake. Therefore, the generated waves do not change with the viewing angle, nor do they fit the terrain behind the lake, and look more natural.

[0055] Figure 7 The present invention provides a schematic diagram of a structure of a device for rendering waves in a virtual scene. Figure 7 As shown, the rendering device of the waves in the above virtual scene includes:

[0056] The acquisition module 702 is used to acquire a first normalization result and a second normalization result, wherein the first normalization result is a normalization result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the terrain model intersecting with the water surface model, and the second normalization result is a normalization result of the distance from each point on the intersection line of the water surface model and the terrain model to a standard point on the intersection line, where the standard point is a point determined from the intersection line;

[0057] A determination module 704, configured to determine the texture mapping coordinates of the water surface model according to the first normalization result and the second normalization result;

[0058] The mapping module 706 is used to map the wave spray map to the texture map coordinates and control the wave spray map to scroll within a certain range.

[0059] The virtual three-dimensional scene in this embodiment includes at least a water surface model and a terrain model. The terrain model may be a shore (or may include part of the land below the water surface or only the shore), and the water surface model is part of the water surface. Figure 2 It is an exemplary top view of the shore and water surface of a certain area, wherein part 202 is the shore, part 204 is the water surface, and the two intersect at an intersection line. Figure 3 is a schematic cross-sectional view (side view) of the two, wherein the shore portion 302 and the water surface model portion 304 intersect. In this embodiment, when performing data calculation, the horizontal surface portion 306 of the terrain model 302 and the horizontal surface portion 306 of the water surface model can be used for calculation to determine the wave map, without calculating the underground and underwater parts. The terrain model and water surface model mentioned in the text refer to Figure 3 The horizontal plane portion 306 in the.

[0060] The first normalized result is the normalized result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the intersection line where the water surface model and the terrain model intersect. The intersection of the water surface model and the terrain model on the horizontal plane forms a curve, which can be called the intersection line. Each vertex on the water surface model can be a vertex on the horizontal plane of the water surface model, or all vertices on the horizontal plane and the part below the horizontal plane. Calculate the distance from the vertex to the intersection line, normalize the distance, and obtain the first normalized result.

[0061] The above second normalization result is to select a point on the above intersection line as a standard point, the standard point is randomly selected, and then calculate the distance from each point on the intersection line to the standard point, and normalize the distance to obtain the second normalization result.

[0062] According to the first normalization result and the second normalization result, the texture map coordinates of the water surface model can be determined. The texture map coordinates are used to mark the position of the texture map, that is, where on the water surface model the texture map of the water surface model is pasted.

[0063] After the texture coordinates are determined, the wave map can be mapped to the texture coordinates. In addition, the wave map can be controlled to scroll within a certain range to achieve the effect of lake waves.

[0064] This embodiment obtains a first normalization result and a second normalization result, wherein the first normalization result is a normalized result of the distance from each vertex on the water surface model in the virtual three-dimensional scene to the terrain model intersecting with the water surface model, and the second normalization result is a normalized result of the distance from each point on the intersection line of the water surface model and the terrain model to a standard point on the intersection line, and the standard point is a point determined from the intersection line; determines the texture map coordinates of the water surface model according to the first normalization result and the second normalization result; and maps a wave map to the texture map coordinates and controls the wave map to scroll within a certain range. When displaying virtual waves, the texture map coordinates of the water surface model can be determined through the water surface model and the terrain model, and the wave map is mapped on the texture map coordinates, and the wave map is controlled to scroll within a certain range, thereby ensuring that the direction of the wave map is fixed and the effect of scrolling within a certain range is achieved, realizing the simulation of the waves, and solving the problem of poor display effect of the waves in the prior art.
