Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, storage medium and electronic device for generating virtual ocean waves. Background Art

[0002] In the production of virtual scenes or computer animations, the rendering and design of virtual wave foam effects are often involved. In the related art, there are mainly two methods for rendering virtual waves.

[0003] The first method is to match the screen with the pre-made dynamic wave foam material through the grid deformation function in the design software (such as AE) to achieve the virtual wave foam effect in the screen. This method is low-cost and suitable for application scenarios with simple requirements. However, it is difficult to apply to scenes with complex requirements (such as large or irregular areas to be rendered), and it is more dependent on the original material and has poor scalability.

The cloud game server runs the game according to the operation instruction, encodes and compresses the game screen and other data, and returns it to the client device through the network. Finally, the client device decodes and outputs the game screen.

[0058] In an optional embodiment, taking a game as an example, a local terminal device stores a game program and is used to present a game screen. The local terminal device is used to interact with the player through a graphical user interface, that is, the game program is downloaded and installed by an electronic device and run conventionally. The local terminal device may provide the graphical user interface to the player in a variety of ways, for example, it may be rendered and displayed on a display screen of the terminal, or provided to the player through a holographic projection. For example, the local terminal device may include a display screen and a processor, the display screen is used to present a graphical user interface, the graphical user interface includes a game screen, and the processor is used to run the game, generate a graphical user interface, and control the display of the graphical user interface on the display screen.

[0059] In a possible implementation, an embodiment of the present invention provides a method for generating virtual ocean waves, providing a graphical user interface through a terminal device, wherein the terminal device may be the local terminal device mentioned above, or may be a client device in the cloud interaction system mentioned above. Figure 2 is a flow chart of a method for generating virtual ocean waves according to one embodiment of the present invention, wherein a graphical user interface is provided by a terminal device, and the content displayed by the graphical user interface includes a touch area, such as Figure 2 As shown, the method comprises the following steps:

[0060] Step S21, obtaining a background image to be superimposed, wherein the display content in the background image includes: a target boundary, which is a boundary where a virtual water surface area contacts a virtual land area;

[0061] The background image to be superimposed may be an image frame (full or partial image) of a virtual game scene to be rendered with a virtual wave effect, or an image frame (full or partial image) of a computer animation to be added with a virtual wave effect.

[0062] The display content in the above background image may include the above target boundary. The target boundary may be the boundary where a virtual water surface area (such as oceans, rivers, streams, lakes and other water areas in a virtual scene) and a virtual land area (such as green land, beaches, reefs, bridges, roads and other areas in a virtual scene) touch each other.

[0063] Step S22, generating a virtual sheet model based on the target boundary, wherein the virtual sheet model is used to determine a virtual wave surface to be displayed at the target boundary;

[0064] The virtual film model can be used to determine the virtual wave surface to be displayed at the target boundary. The virtual film model can be a two-dimensional area model corresponding to the area to be rendered for the virtual wave effect.

[0065] For example, for a virtual coastline between a virtual ocean area and a virtual beach area (equivalent to the target boundary), the virtual film model may be a two-dimensional area model near the virtual coastline where the wave foam effect is to be rendered.

[0066] Step S23, obtaining a target map, wherein the target map is used to determine virtual waves to be displayed at the target boundary;

[0067] The target map can be used to determine the virtual waves to be displayed at the target boundary. For example, in an actual application scenario, the target map can be a wave map sequence made based on the initial wave surface model according to the virtual ocean area and the virtual beach area.

[0068] Specifically, obtaining the target map also includes other method steps, which can be referred to the further introduction of the embodiments of the present invention below and will not be described in detail here.

[0069] Step S24, adding the target map to the virtual film model to obtain a first processing result, wherein the first processing result is used to determine the wave foam effect to be displayed at the target boundary;

[0070] The target map is used to determine the virtual waves to be displayed at the target boundary, and the virtual film model is used to determine the virtual wave surface to be displayed at the target boundary. The target map is added to the virtual film model to obtain the first processing result. The first processing result can be used to determine the wave foam effect to be displayed at the target boundary.

[0071] For example, by adding the wave map sequences corresponding to the virtual ocean area and the virtual beach area to the corresponding virtual coastline model, the wave foam effect to be displayed on the virtual coastline can be determined.

[0072] Specifically, the target map is added to the virtual slice model to obtain the first processing result, which also includes other method steps, which can be referred to the further introduction of the embodiment of the present invention below and will not be described in detail here.

[0073] Step S25, superimposing the background image and the first processing result to obtain a second processing result, wherein the second processing result is used to generate a wave synthesis effect at the target boundary.

[0074] The second processing result may be used to generate a wave synthesis effect on a target boundary where the virtual water surface area contacts the virtual land area.

[0075] For example, the image frames corresponding to the virtual ocean area and the virtual beach area (equivalent to the above-mentioned background image) are superimposed with the wave foam effect to be displayed on the virtual coastline, so as to obtain the wave synthesis effect between the virtual ocean area and the virtual beach area. The above-mentioned superimposition processing can be superimposition and post-processing rendering, or optimization adjustment processing and superimposition rendering.

[0076] In at least some embodiments of the present invention, a background image to be superimposed is obtained, wherein the display content in the background image includes: a target boundary, which is a boundary where a virtual water surface area contacts a virtual land area; a virtual film model is generated based on the target boundary, wherein the virtual film model is used to determine a virtual wave surface to be displayed at the target boundary; and a target map is obtained, wherein the target map is used to determine virtual waves to be displayed at the target boundary; a first processing result is obtained by adding the target map to the virtual film model, wherein the first processing result is used to determine a wave foam effect to be displayed at the target boundary; the background image and the first processing result are superimposed to obtain a second processing result, wherein the second processing result is used to generate a wave synthesis effect at the target boundary, thereby achieving the purpose of obtaining a virtual wave effect by superimposing a virtual wave map on the background image, thereby achieving the technical effect of improving the virtual wave rendering efficiency at a relatively low cost, thereby solving the technical problem of the virtual wave rendering method provided by the related art having high rendering difficulty and low efficiency.

[0077] The above method of the embodiment of the present invention is further introduced below.

[0078] Optionally, in step S21, obtaining the background image may include the following execution steps:

[0079] Step S211, projecting the original image onto the target grid, wherein the display content in the original image includes: a plurality of candidate boundaries;

[0080] Step S212, adjusting the camera angle of the virtual camera to shoot the target grid to obtain a background image.

[0081] The original image may be an image frame of a virtual game scene in which a virtual image is to be rendered with a virtual wave effect. The original image may display multiple boundaries of the virtual wave effect to be rendered (which may be boundaries where a virtual water surface area contacts a virtual land area).

[0082] Figure 3 is a schematic diagram of an optional background image according to an embodiment of the present invention, such as Figure 3 As shown, when rendering the virtual wave effect for the annular area 1, the original image showing the annular area 1 is first projected into the target grid grid01 (as shown in FIG. Figure 3Then, according to the virtual camera direction corresponding to the target grid grid01, adjust to restore the horizontal perspective, and obtain the background image corresponding to the annular area 1 by cropping (as shown in Figure 1). Figure 3 2 in the image).

[0083] Optionally, in step S22, generating a virtual slice model based on the target boundary may include the following execution steps:

[0084] Step S221, drawing a target line according to the target boundary;

[0085] Step S222, determining a first direction and a second direction of the target line, wherein the first direction is a path direction of the target line, and the second direction is a direction perpendicular to the first direction;

[0086] Step S223, determining the width of the target line in the second direction;

[0087] Step S224: Generate a virtual slice model based on the width.

[0088] The target boundary is the boundary where the virtual water surface area and the virtual land area touch each other, and the target line is drawn according to the target boundary. The target line is used to determine the position and shape of the virtual film model.

[0089] According to the target line, the path direction of the target line can be determined as the first direction, and the vertical direction of the first reverse direction can be determined as the second direction. The width of the target line is determined in the second direction. The width is used to determine the range of the virtual film model.

[0090] Based on the width of the target line, the virtual sheet model can be generated, which is used to determine the virtual wave surface to be displayed at the target boundary.

[0091] Figure 4 is a schematic diagram of an optional virtual slice model according to an embodiment of the present invention, such as Figure 4 As shown, according to the annular area 1, the corresponding boundary line (equivalent to the above-mentioned target line) is determined; then, the width d of the boundary line is determined in a direction perpendicular to the path of the boundary line; according to the width d, it can be determined as follows Figure 4 The area corresponding to the virtual film model M1 in .

[0092] It should be noted that Figure 4 The area corresponding to the virtual sheet model M1 shown is the area where the virtual wave model is added to the annular area 1.

[0093] Optionally, the above virtual ocean wave generation method may further include the following execution steps:

[0094] Step S26, determining the texture coordinates to be used according to the first direction and the second direction;

[0095] Step S27, creating a multi-layer texture mask based on the texture coordinates to be used, wherein the multi-layer texture mask is used to randomly adjust the display effect of the virtual waves in the time dimension.

[0096] According to the first direction and the second direction of the target line, the texture coordinates to be used may be determined. In an actual application scenario, the texture coordinates to be used may be normalized UV coordinates.

[0097] Based on the texture coordinates to be used, the multi-layer texture mask can be created, which can be used to randomly adjust the display effect of virtual waves in the time dimension. In actual application scenarios, according to the normalized UV coordinates, multiple texture masks can be created to control the lifespan of virtual waves in the virtual ocean (such as appearance time and disappearance time, etc.).

[0098] Still like Figure 4 As shown, in the area corresponding to the virtual film model M1, the texture coordinate grid02 (which can be normalized, that is, with size and direction and its size is normalized to 1) can be determined according to the path direction and the vertical direction of the path of the boundary line of the annular area 1.

[0099] Still for example, when rendering the virtual wave effect for the annular area 1, two masks for controlling the random display effect of the virtual waves in the time dimension can be created based on the texture coordinate grid02, which are respectively recorded as maskA and maskB.

[0100] It should be noted that when creating a texture mask for randomly adjusting the display effect of virtual waves in the time dimension, the number of the texture masks can be determined according to the needs of the actual application scenario. The more texture masks created, the more virtual wave rendering resources are required.

[0101] Optionally, in step S23, obtaining the target map may include the following execution steps:

[0102] Step S231, obtaining a virtual initial wave surface;

[0103] Step S232, adjusting the morphological parameters of the virtual initial wave surface to obtain a virtual target wave surface;

[0104] Step S233, determining a plurality of target points on the virtual target wave surface, wherein the plurality of target points are used to determine the generation position of the wave foam effect;

[0105] Step S234, performing speed adjustment and disturbance processing on the multiple target points to obtain a third processing result, wherein the third processing result is used to determine the tailing effect of the wave foam;

[0106] Step S235, performing volume conversion on the third processing result to generate a target map.

[0107] The virtual initial wave surface may be a virtual wave surface model made using preset software (such as the small-scale ocean tool in Houdini's tool shelf). The virtual wave surface model may include morphological parameters, which are used to control the display morphology of the virtual waves.

[0108] According to the requirements of the actual application scenario, the morphological parameters of the virtual initial wave surface are adjusted to obtain the above-mentioned virtual target wave surface.

[0109] On the virtual target wave surface, the above-mentioned multiple target points can be determined. The multiple target points can be used to determine the generation position of the wave foam effect. For example, the multiple target points can be multiple wave crest emission points on the virtual target wave surface.

[0110] The above-mentioned third processing result can be obtained by performing speed adjustment and disturbance processing on the above-mentioned multiple target points. The third processing result can be used to determine the tailing effect of the sea foam. The speed adjustment can be to determine the initial speed for each target point of the multiple target points, and the disturbance processing can be to determine the disturbance parameter for each target point of the multiple target points.

[0111] The target map can be generated by performing volume conversion on the third processing result. The target map is used to determine the virtual waves to be displayed at the target boundary. The volume conversion can add a volume effect to the display effect of the virtual waves.

[0112] Optionally, in step S232, the morphological parameters include one or more of the following:

[0113] A first morphological parameter, wherein the first morphological parameter is used to adjust the texture accuracy of the virtual initial wave surface;

[0114] A second morphological parameter, wherein the second morphological parameter is used to adjust the texture tiling size of the virtual initial wave surface;

[0115] A third morphological parameter, wherein the third morphological parameter is used to adjust the speed attribute of the virtual initial wave surface;

[0116] A fourth morphological parameter, wherein the fourth morphological parameter is used to adjust the movement direction of the virtual initial wave surface;

[0117] The fifth morphological parameter is used to adjust the wave crest properties of the virtual initial wave surface.

[0118] The above-mentioned morphological parameters for controlling the display morphology of the virtual ocean waves may include one or more items. In actual application scenarios, the morphological parameters specifically include one or more of the above-mentioned first morphological parameters, second morphological parameters, third morphological parameters, fourth morphological parameters and fifth morphological parameters, which may be determined according to scenario requirements or user settings.

[0119] Let's take the rendering of virtual waves in ring area 1 as an example. Figure 5 is a schematic diagram of an optional virtual target wave surface according to an embodiment of the present invention. An initial wave surface P0 is generated using the small-scale ocean tool in Houdini software, and multiple parameters of the initial wave surface P0 are adjusted to obtain the following: Figure 5 The target wave surface P1 shown (equivalent to the virtual target wave surface mentioned above).

[0120] Specifically, adjusting multiple parameters of the initial wave surface P0 includes the following steps:

[0121] Step E51, adjusting the texture precision parameter Resolution Exponent (equivalent to the first morphological parameter) to 9 (the larger the value, the higher the texture precision);

[0122] Step E52, adjusting the texture tiling size parameter Grid Size (equivalent to the above-mentioned second morphological parameter) to 50 (the smaller the value, the higher the repetition of the wave surface texture);

[0123] Step E53, adjusting the speed attribute parameter speed (equivalent to the third morphological parameter) to 17 (the larger the value, the larger the size of the virtual wave);

[0124] Step E54, adjusting the motion direction parameter Directional bias (equivalent to the fourth morphological parameter) to 5 (the smaller the value, the more uniform the motion direction of the virtual waves, and the larger the value, the more chaotic the motion direction of the virtual waves);

[0125] Step E55, adjust the wave crest attribute parameter chop (equivalent to the fifth morphological parameter mentioned above) to 0.6 (the larger the value, the sharper the wave crest of the virtual wave, and the smaller the value, the softer the wave crest of the virtual wave).

[0126] It should be noted that in the above step E55, it is necessary to avoid the virtual waves in the virtual scene from interlacing, and it is also necessary to ensure that the wave crests are sharp enough to facilitate the generation of wave crest attributes.

[0127] Optionally, in step S233, determining a plurality of target points on the virtual target wave surface may include the following execution steps:

[0128] Step S2331, randomly distributing multiple candidate points on the virtual target wave surface;

[0129] Step S2332, selecting multiple target points from multiple candidate points based on the fifth morphological parameter.

[0130] Still taking the rendering of the virtual wave effect in the annular area 1 as an example, randomly scatter points on the virtual target wave surface P1 to obtain multiple candidate points. Then, according to the wave crest attribute parameter chop, some candidate points are deleted from the multiple candidate points to obtain the multiple target points. The multiple target points can be used as wave crest emission points on the virtual target wave surface P1.

[0131] Specifically, the value of the wave crest attribute parameter chop is between 0 and 1, and the closer the value is to 1, the closer it is to the wave crest. According to the needs of the actual scene, points whose values ​​of the wave crest attribute parameter chop are specified values ​​(or are in a specified interval) are deleted from multiple candidate points, thereby obtaining the above multiple target points.

[0132] Still taking the rendering of the virtual wave effect in the annular area 1 as an example, based on the above-mentioned multiple target points, a speed value v0 and a disturbance parameter r0 are determined for each of the multiple target points, and the virtual wave surface P3 (equivalent to the above-mentioned third processing result) can be obtained, and then maskA and maskB are updated to obtain the trailing effect and random display life of the virtual waves.

[0133] Still taking the rendering of the virtual wave effect in the annular area 1 as an example, the particles emitted by the multiple wave crest emission points (equivalent to the multiple target points) corresponding to the virtual wave surface P3 are cached to obtain the cache result L0. The number of cached frames can take a larger value to obtain more materials to ensure the richness of the virtual wave foam effect.

[0134] Optionally, in step S235, performing volume conversion on the third processing result to generate a target map may include the following execution steps:

[0135] Step S2351, performing volume conversion on the third processing result to generate an initial map;

[0136] Step S2352, performing seam processing and feathering processing on the initial texture to obtain a target texture.

[0137] The third processing result for determining the trailing effect of the sea foam is subjected to volume conversion processing to generate an initial map. Further, the initial map is subjected to seam processing and feathering processing to obtain the target map. The target map is used to determine the virtual waves to be displayed at the target boundary.

[0138] Still taking the rendering of the virtual wave effect in the annular area 1 as an example, the cache result L0 corresponding to the multiple wave crest emission points (equivalent to the multiple target points) corresponding to the virtual wave surface P3 is volume-converted to obtain the initial map.

[0139] Specifically, a density attribute is added to the particles in the cache result L0, and the density attribute is initialized to 1. A pscale attribute is added to the particles in the cache result L0 to control the size of the particles: the pscale attribute value can be obtained by randomly processing the life of the particles; the pscale attribute value can be a specified fixed value (such as 0.01); the pscale attribute value can be a random number within a specified range.

[0140] It should be noted that the value of the pscale attribute needs to be adjusted according to the display size of the particle after volume conversion.

[0141] Figure 6 is a schematic diagram of an optional volume conversion result according to an embodiment of the present invention. By using the volume rasterize node in Houdini, the particles in the cache result L0 are converted into volumes according to the density attribute of the particles. Specifically, the Voxel Size parameter is set to 0.1; the Particle Scale parameter is set to 1; the Minimum FilterSize parameter is set to 0.75; the Shutter parameter is set to 0.5; the Shutter Offset parameter is set to 1; the BlurSamples parameter is set to 4; and the Coverage Scale parameter is set to 1. The volume conversion result is as follows: Figure 6 shown.

[0142] Figure 7 is a schematic diagram of an optional initial map according to an embodiment of the present invention, such as Figure 7 As shown, based on the volume conversion result, a camera rendering sequence is obtained according to the top view of the volume conversion result, and then the following is obtained: Figure 7 The initial texture asset shown in .

[0143] Still taking the rendering of virtual waves effect in annular area 1 as an example, Figure 7 The initial texture material shown is imported into post-processing software (such as AE) for left-right seamless processing and up-down feathering disappearance processing to obtain the target texture material P4. The target texture material can be returned to Houdini to obtain an updated camera rendering sequence.

[0144] It should be noted that performing left-right seamless processing on the initial texture material can avoid the seam effect of the virtual waves; performing up-down feathering disappearance processing on the initial texture material can avoid the hard cutting effect of the virtual waves.

[0145] Optionally, in step S24, adding the target map to the virtual slice model to obtain the first processing result may include the following execution steps:

[0146] Step S241, adding the target map to the virtual patch model based on the texture coordinates to be used, to obtain a fourth processing result;

[0147] Step S242, mixing the fourth processing result with the multi-layer texture mask to obtain the first processing result.

[0148] The texture coordinates to be used may be normalized UV coordinates determined according to the first direction and the second direction of the target line. Based on the texture coordinates to be used, the target map may be added to the virtual slice model to obtain the fourth processing result.

[0149] Still taking the rendering of the virtual wave effect in the annular area 1 as an example, according to the texture coordinate grid02, the camera rendering sequence corresponding to the target map material P4 is added to the virtual wave surface P3, and the virtual wave surface P5 (equivalent to the fourth processing result mentioned above) can be obtained.

[0150] It should be noted that for the camera rendering sequence corresponding to the target texture material P4, AE or Houdini can be used for time frame error processing to enhance the randomness of the virtual waves in the time dimension, avoid the repetition of virtual waves in the virtual waves, and enhance the virtual reality effect of the virtual waves.

[0151] The virtual wave surface P5 is mixed with maskA and maskB to obtain a virtual wave model P6 (equivalent to the first processing result). The virtual wave model P6 can be used to determine the wave foam effect to be displayed on the coastline corresponding to the annular area 1.

[0152] Figure 8a is a schematic diagram of an optional virtual spray material according to an embodiment of the present invention, such as Figure 8a The figure shows a schematic diagram of the wave material in maskA; Figure 8b is a schematic diagram of another optional virtual spray material according to an embodiment of the present invention, such as Figure 8b The following is a schematic diagram of the wave material in maskB. Figure 8a and Figure 8b As shown, the wave materials in maskA and maskB can be set as self-luminous materials, without calculating the light and shadow information of the virtual waves, thereby improving the rendering efficiency of the virtual waves.

[0153] Still taking the rendering of the virtual wave effect of the annular area 1 as an example, the virtual wave model P6 is superimposed on the background image corresponding to the annular area 1, and then the virtual wave foam effect corresponding to the annular area 1 can be obtained.

[0154] It is easy to notice that according to the method provided by the embodiment of the present invention, a virtual ocean wave effect is obtained by superimposing a virtual wave texture on a background image, which has the beneficial effect of improving the efficiency of virtual ocean wave rendering at a relatively low cost.
