Detailed Description

To make the objects, technical solutions and advantages of the present specification more apparent, the present specification is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.

It should be noted that technical terms or scientific terms used in the embodiments of the present application should have a general meaning as understood by those having ordinary skill in the art to which the present application belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that a element, article, or method step that precedes the word, and includes the element, article, or method step that follows the word, and equivalents thereof, does not exclude other elements, articles, or method steps. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As described in the background art, in the traditional mode of directly using a model for k animation, if the skeleton animation is a skeleton animation, the skeleton animation is difficult to bind, and the skeleton animation is inconvenient to modify and adjust after being manufactured. And if the k model animation is directly carried out, the dynamic is mechanical without water agility. The k animation, the k action and the like refer to the process of animation or action after an animation production engineer binds bones and skins to the model. At present, the traditional manufacturing processes mainly comprise two types: 1) playing the cartoon sequence frame map by using a particle transmitter to realize a ripple effect; 2) a houdini (a three-dimensional computer graphics making software) is used to simulate the ripple effect, a set of sequence models is derived, and then the ripple effect is achieved by the particle launching sequence models. Both of these techniques have some drawbacks. The first technique, with sequential frames, can produce severe stuck phenomena under slow-shots, greatly affecting the artistic expression and user experience. The second technique, model sequence, is not suitable for high-precision effect, the number of models is too large, a large amount of resources are occupied, the second technique is not suitable for mobile equipment platforms, and the second technique is more suitable for some projects of host terminals or terminals. Therefore, a ripple generating scheme is needed at the mobile device end, in which a vivid ripple effect can be generated by using fewer maps, the overhead cost is low, and the ripple effect can be conveniently and quickly adjusted in a shader (shader).

In combination with the above actual situation, an embodiment of the present application provides a water ripple generation scheme, where a water ripple model is constructed, a UV map of the water ripple model is obtained, a final target gradient map is obtained by combining the UV map with a corresponding preset noise map, and the final water ripple is mapped and rendered through the target gradient map. Therefore, the scheme for conveniently and quickly completing the water body corrugation manufacturing and adjusting is provided, and the overall manufacturing efficiency is improved. And the scheme utilizes less pastels to reduce the manufacturing cost, and the manufacturing effect can be quickly checked after adjustment, thereby saving a large amount of manufacturing time.

As shown in fig. 1, a schematic flow chart of a water body ripple generating method proposed by the present application is provided, where the method specifically includes:

step 101, constructing a water body ripple model, and obtaining a UV map of the water body ripple model.

In this step, a model of the waviness of the body of water is generated from a surface model capable of generating waviness, typically a surface model of a solution, such as a water surface model, a water droplet model, a solvent surface model, and the like. Then, the surface model is generally a plane model, and the corrugations are generally an arc model with a certain radian, a water body corrugation model, and also generally a circular model radiating from a central point generated by the corrugations to the periphery, as shown in fig. 2, the water body corrugation model is a model after the plane model is deformed by bending and the like. Furthermore, the basic plane model needs to be bent to generate the water body ripple model, and the water body ripple model is bent to form a ripple basic shape, such as a circular ring or an irregular ring, and the bending process may be bending the model through a preset template, or directly adjusting the basic model by a user engineer, or loading a modifier for bending on the basic model, and directly adjusting the modifier by the user engineer through parameter adjustment or artificial intelligence calculation parameters, and the like. Thereby obtaining a circular or irregular annular water body ripple model. Of course, the specific shape of the water ripple model can be specifically adjusted according to the specific application scenario, and the water ripple model generally corresponds to the approximate shape of the ripple.

And then, acquiring a UV map of the water body ripple model. Generally, a texture is one or several two-dimensional graphics, also called texture maps (texture), representing the surface of an object. When the texture is mapped onto the surface of the object in a specific way, the object can be more truly seen. In the case of three-dimensional animation and game production, UV texture mapping or UVW texture mapping, etc. are generally used. Taking the UV texture map as an example, the UV map is a planar representation of the three-dimensional model surface for easy packing textures, and the U-channel and V-channel refer to the horizontal and vertical axes of a two-dimensional space. Specifically, U, V is short for the coordinates of the UV texture map) which is similar to the X, Y, Z axis of the spatial model). Information defining the position of each point on the picture, which points are interrelated with the three-dimensional model for determining the position of the surface texture map. As if it were a virtual "woundplast," UV is the exact correspondence of each point on the two-dimensional image to the surface of the three-dimensional model object. The position of the gap between the point and the point is subjected to image smoothing interpolation processing by specific software. In this step, after the water body ripple model is determined, the UV map of the water body ripple model may be directly obtained through third-party software or a functional module.

And 102, overlapping the UV maps according to a preset noise wave map to obtain a target gradual change map.

In this step, after the UV map is obtained, calculation of the target gradient map may be performed. The gradient graph is generally an image in which patterns or colors in the graph gradually change with the movement of coordinate axes. In a specific embodiment, the gradient map of the ripple is generally related to propagation velocity of the ripple, initial impact strength (propagation amplitude), model material, and the like, so that the gradient map of the ripple can be calculated based on the UV map by using parameters that affect all or part of the ripple shape. In a specific embodiment, the target gradient map may be driven only for the vertex of the model or the map, and other points are driven by the vertex, that is, the propagation of the ripple may be performed by means of vertex offset. In a specific embodiment, taking calculation of a target gradient map through a propagation speed and a system time as an example, a product of a ripple flow speed and a system time parameter can be superimposed through a value of a U channel of a UV map, a decimal part of a superimposed value result is determined, a distance between a position corresponding to the decimal part of the superimposed value result and a central position is determined, and an index is obtained by combining with a regulating variable, so that a gradient map is finally obtained, wherein the gradient map can be an intermediate gradient map or can be directly applied as a final gradient map. When the gradient graph is used as the middle gradient graph, the preset noise graph can be combined to adjust the gradient graph to be more corresponding to the shape of the ripple. In a specific embodiment, the preset noise maps may be tessen polygons, i.e., voronoi maps, black-and-white noise maps, and the like, and these noise maps are combined with the intermediate patterns calculated by the UV map in a multiplication manner to obtain the final target gradient map. Then, in some embodiments, the shape of the ripple may be further adjusted, such as edge hooking, disturbance, and the like, so that the ripple better conforms to the environment of the basic model, and the ripple effect is more real.

In some embodiments, coordinates of the more edges of the UV map corresponding to the ripples may be determined, and coordinates of these locations may be determined using the distance from the center. For a ring of corrugations, it is essentially a ring or a disc, so that the corrugation can be made by adjusting its edge. Then, since the UV map is substantially a coordinate map, the position information of each point in the image is reflected. So that the coordinates of the edges of the intermediate model can be accurately determined based on the coordinate values (UV values, etc.).

Step 103, mapping the target gradient map to the water body ripple model to render and display water body ripples.

In this step, the calculated target gradient map is mapped onto the water body ripple model, so that coordinates (e.g., vertex coordinates) of each point of the water body ripple model are correspondingly adjusted through the target gradient map, and rendering is performed in this way, so that corresponding water body ripples are finally generated. As shown in fig. 3, the target gradient map is mapped onto the water ripple model, and then the water ripple is rendered.

The water ripple may then be output for storage, display, use, or reprocessing. According to different application scenes and implementation requirements, the specific output mode of the water body ripple can be flexibly selected.

For example, for an application scenario in which the method of the present embodiment is executed on a single device, the water ripple may be directly output in a display manner on a display unit (a display, a projector, etc.) of the current device, so that an operator of the current device can directly see the content of the water ripple from the display unit.

For another example, for an application scenario executed by a system composed of multiple devices by the method of this embodiment, the water ripple may be sent to other preset devices serving as receivers in the system, that is, the synchronization terminal, through any data communication manner (such as wired connection, NFC, bluetooth, wifi, cellular mobile network, etc.), so that the synchronization terminal may perform subsequent processing on the water ripple. Optionally, the synchronization terminal may be a preset server, the server is generally arranged at a cloud end, and is used as a data processing and storage center, which can store and distribute the water ripple; where the recipients of the distribution are terminal devices, the holders or operators of these terminal devices may be current users, downstream games, animators, games, quality supervisors of animations, and so on.

For another example, for an application scenario executed by a system composed of multiple devices, the method of this embodiment may directly send the water body ripple to a preset terminal device through any data communication manner, where the terminal device may be one or more of the foregoing paragraphs.

From the foregoing, it can be seen that a method for generating waviness of a water body according to an embodiment of the present application includes: constructing a water body ripple model and obtaining a UV (ultraviolet) map of the water body ripple model; according to a preset noise wave diagram, carrying out superposition processing on the UV map to obtain a target gradual change diagram; and mapping the target gradient map into the water body ripple model so as to render and display water body ripples. According to the method, a water body ripple model is constructed, a UV map of the water body ripple model is obtained through the UV map, a final target gradient map is obtained through combination with a corresponding preset noise map, and final water body ripple is mapped and rendered through the target gradient map. Therefore, the scheme for conveniently and quickly completing the water body corrugation manufacturing and adjusting is provided, and the overall manufacturing efficiency is improved. And the scheme utilizes less pastels to reduce the manufacturing cost, and the manufacturing effect can be quickly checked after adjustment, thereby saving a large amount of manufacturing time.

It should be noted that the method of the embodiment of the present application may be executed by a single device, such as a computer or a server. The method of the embodiment of the application can also be applied to a distributed scene and is completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment, and the multiple devices interact with each other to complete the method.

It should be noted that the above-mentioned description describes specific embodiments of the present application. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In an alternative exemplary embodiment, the constructing a water ripple model includes: acquiring a water body plane model, and determining plane vertex coordinates of the water body plane model; and adjusting the plane model of the water body into a circular plane model by adjusting the coordinates of the top point of the plane, so as to generate the water body ripple model. Therefore, the water body plane model is quickly adjusted in a mode of adjusting the water body plane model into the circular plane model, so that the water body plane model becomes a desired water body ripple model.

In this embodiment, the water plane model is a surface model capable of generating ripples, such as a water surface model, a water drop model, a solvent surface model, and the like. Because the ripple is a local phenomenon in the water surface, a small water body plane model can be selected to create the water body ripple model, for example, a rectangular or square water body plane model is set. And then, after the model is determined, corresponding vertexes, vertex coordinates and the like are all determined, and a circular plane model can be finally generated by adjusting the vertex coordinates of the water body plane model to serve as a water body ripple model.

In a specific embodiment, the planar model may be adjusted by using some third-party three-dimensional modeling software, such as 3Dmax, etc., in which a bend modifier is usually provided. In the software, the plane of the water body plane model can be adjusted by the bending modifier in a mode of directly loading the bending modifier on the water body plane model, so that the bending is realized according to the setting or the adjustment of a user. The loading of the bend modifier may also be performed by first adding the bend modifier to a particular mold and then loading the mold onto the water body planar model. As shown in fig. 2, the water body plane model is adjusted by using modeling software such as 3Dmax, and the final generated model is the water body ripple model. In a specific embodiment, for factors such as the magnitude of the specific bending adjustment, i.e. the size of the ripple that is desired to be reflected, the animation itself is involved, so that an animation engineer needs to actively adjust and set, and the system performs, i.e. obtains the setting information for the bending modifier.

In one embodiment, the adjustment to the water plane model may be performed by creating a patch. The patch is a graph between two-dimensional and three-dimensional, and has a three-dimensional surface, but the two-dimensional spline curve is kept, and the curved surface effect can be achieved by adjusting the Bezier handle. Therefore, in three-dimensional modeling software, a patch is generally used to produce soft cloth (clothes, tablecloth, bedspread, etc.), mountainous regions, water surface, etc. In a specific application scenario, an adjusting patch capable of covering a water body plane model can be created in three-dimensional modeling software such as 3Dmax, then a band modifier is added on the adjusting patch, finally the adjusting patch added with the band modifier is loaded to a base model, and an animation engineer sets the band modifier to complete bending of the base model.

In an alternative exemplary embodiment, the water body plane model is a quadrilateral plane model; the adjusting the plane model of the water body into a circular plane model comprises: and carrying out plane adjustment on the quadrilateral plane model to enable two opposite sides of the quadrilateral plane model to be overlapped, and stretching or compressing the other two opposite sides of the quadrilateral plane model to obtain the circular plane model.

In the present embodiment, the quadrangular plane model may be a rectangular plane model or a square plane model, or the like. Taking a rectangular plane model as an example, which is a rectangle in a plan view, when performing adjustment, the whole rectangle can be bent and stretched in the plane so that two short sides of the rectangle are overlapped. In order to accomplish this adjustment, one of the two long sides of the adjustment must be stretched and the other compressed, and finally, the stretched side becomes the outer contour line of the circle or ring, and the compressed side becomes the center or inner contour line of the circle or ring. Similar operations may of course be performed for square planar models, parallelogram planar models, rhomboid planar models, etc. The person skilled in the art can make specific adjustments to the quadrilateral planar model according to specific application scenarios.

In an optional exemplary embodiment, before the overlaying the UV map, the method includes: and acquiring a ripple flowing speed and a time parameter, calculating according to the ripple flowing speed and the time parameter to obtain a middle value of a gradual change graph of the UV mapping, and overlapping the middle value of the gradual change graph and the preset noise graph.

In this embodiment, the ripple flow velocity is the propagation velocity of ripples, for example, after a stone is thrown into a lake, the propagation velocity of ripples generated is determined by the water entry velocity and water entry volume of the stone, and the animation engineer may directly give a value of the ripple flow velocity. The time parameter is then a system time parameter, which may be given by an engineer or may be calculated or statistically derived, for example by counting the time that starts when a stone is thrown into the lake and giving it. Furthermore, a middle gradient map, i.e., a gradient map median, can be generated by combining the coordinate values of the individual points in the UV map using the ripple flow rate and the time parameter. The specific calculation process may be:

wave_intensity

＝pow((((1.0-distance(frac((v.texcoord.xy.x+(_speed*_Time.y)))，0.5))+-05)*2.0)，_power)

wherein, wave _ intensity is a middle value of the gradient map, v.texcoord.xy.x is a coordinate value of a set coordinate direction of the texture map, _ speed is a ripple flow speed, _ time.y is a system time parameter, and _ power is a preset adjusting variable parameter. frac (x) represents a function that takes the fractional part of x, in this example the fractional part of the calculated result ((v.texcoord. xy. x + (_ speed. time. y))); distance (x, y) represents a function of the distance between x and y, in this embodiment, the distance (frac ((v.texcoord.xy.x + (_ speed _ time.y))), 0.5); pow (x) indicates that the exponential function calculation is performed, in this embodiment, on (((1.0-discrete from v.texcoord. xy.x + _ speed _ time. y, 0.5+ -0.5 x 2.0, _ power).

And finally, after the calculation of the intermediate value of the gradient map is finished, superposing the intermediate value with a preset noise map to finally obtain a target gradient map. In an embodiment, the predetermined noise map may be a Thiessen polygonal noise map. The Thiessen polygons are Voronoi diagrams, which are called Voronoi diagramas (Voronoi diagramas), and are a group of continuous polygons formed by perpendicular bisectors connecting two adjacent point line segments. Any point within a Thiessen polygon is less distant from the control points that make up the polygon than from the control points of other polygons. The noise map is a map reflecting noise. In the field of three-dimensional animation production, noise can provide a waveform diagram with random positions for vertexes, and in the production of a three-dimensional model, the established plane is mainly irregular, uneven and the like. Such as land, cave, etc., the surface of which is irregular in real life, and in order to make the land, cave, etc. in the virtual scene more realistic, it is necessary to load random noise maps, and it is difficult to accurately model using ordinary modeling. In a specific application scenario, the noise map of the voronoi diagram may be set in advance, or may be obtained by directly performing noise calculation using three-dimensional modeling software after obtaining a preset voronoi diagram. The gradient map intermediate values are then superimposed with a preset noise map, such as a Thiessen polygonal noise map. As shown in fig. 4, in which fig. 4a is a middle value of the gradient map in an embodiment, and fig. 4b is a taisen polygon noise map, in an embodiment, the process of superposition is to multiply the channel value or the gray value, etc. of each point calculated from the middle value of the gradient map by the channel value or the gray value, etc. at the same position of the taisen polygon noise map. And finally obtaining a target gradient graph.

In an optional exemplary embodiment, before mapping the target gradient map into the water ripple model, the method further includes: and acquiring a preset black-and-white gradient image, and overlapping the target gradient image and the black-and-white gradient image to obtain an adjusted target gradient image.

The amplitude of the ripple of the target gradient map obtained after the intermediate value of the gradient map is superposed with a preset noise map such as a Thiessen polygonal noise map is the same, that is, the amplitude of the ripple obtained by using the target gradient map is the same no matter how far away the ripple is from the central point of the ripple. Such a ripple map can thus only be used in certain scenarios. In a more realistic scene, the effect of the ripples is that the closer to the central point, the larger the amplitude of the ripples, and the farther from the central point, the smaller the amplitude of the ripples until the ripples disappear. So that further adjustments to the target gradient map may be made. In this embodiment, the above effect can be achieved by adding a black and white gradient map. As shown in fig. 5, the black-and-white gradient map is a normal gradient map gradually changing from black to white, and the adjustment of the target gradient map can be completed by a superposition manner such as multiplication of the target gradient map and the black-and-white gradient map, so as to generate a distance effect. For example, the darker part of the black-and-white gradient map is set to be a position closer to the central point, so that the assignment can be targeted at the assignment, or the distance from the central point can be reflected by the color value (the color value range is generally 0 to 255) of each point of the black-and-white gradient map. Finally, the adjusted target gradient graph is obtained, and the effects of small remote fluctuation and large central fluctuation are achieved.

In an optional exemplary embodiment, before mapping the target gradient map into the water ripple model, the method further includes:

In the present embodiment, the fresnel effect refers to: certain materials exhibit different reflection effects at different distances. The fresnel effect has the following meaning: when light travels from one medium having a refractive index to another medium having a refractive index, reflection and refraction of the light may occur simultaneously at the interface (generally referred to as an interface) of the two. The fresnel equations describe the cases where different light wave components are refracted and reflected. In three-dimensional modeling software, the method can be directly set, so that the system can automatically adjust the map by utilizing the Fresnel effect. In this embodiment, the finished target gradient map may be further processed by edge-pointing through the fresnel effect, so that the generated moire map is more natural and vivid. Wherein, the edge-pointing is one of the conventional steps of drawing.

In an optional exemplary embodiment, before mapping the target gradient map into the water body ripple model, the method further includes: and acquiring a noise map of a preset flow map, and performing superposition processing on the target gradient map by using any color channel of the noise map.

In this embodiment, since in a real scene, the ripples may also be influenced by the flow of the fluid represented by the basic model, for example, the flow of the water surface may cause a perturbation phenomenon in the direction of the water flow motion caused by the ripples. Therefore, after the target gradient map is obtained, the target gradient map can be further modified through a preset noise map of the flow map, so that the target gradient map adapts to the influence of the flow of the fluid presented by the water body model. Then, each point in the map corresponds to at least three color channels, that is, R, G, B channels, so as to reflect the color of each point, and further, in a specific application, the flow disturbance can be reflected by directly obtaining the value (for example, the value of the R channel) of any one channel of each point on the noise map of the preset flow map. And then, the value of the channel can be directly added on the basis of the value of each point of the target gradient map to realize the final disturbance effect of the fluid flow.
