The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Example one

Fig. 1a is a flowchart of a deformation processing method for a model element according to an embodiment of the present invention, where this embodiment is applicable to a case of performing deformation processing on a small object in a virtual interactive scene (a situation that the small object is squeezed all around when passing through by a dynamic object), and the method may be executed by a deformation processing apparatus for the model element, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a terminal or a server (typically, a game server), and the method of this embodiment specifically includes the following steps:

s110, extracting vertex data of the model elements, wherein the vertex data comprises: vertex coordinates of each vertex and information of a center point of the model element.

In this embodiment, the model element refers to a specific individual element of a large number of small objects laid on a screen to be rendered and displayed. For example, the model element may be a flower in a flower sea, a grass in a grass cluster on a lawn, or a leaf on a tree, etc.

In the present embodiment, each model element has a preset number of vertices (generally, a plurality of vertices), where for each model element, vertex data corresponding to the model element needs to be pre-stored. The vertex data includes: vertex coordinates of each vertex and information of a center point of the model element.

And connecting the vertex coordinates of all the vertexes in sequence to obtain the contour shape of the model element.

In general, a model element may include one or more center points that are generally located at the root of the model element proximate the ground. After the central point is set, the root can be guaranteed not to swing interactively when the model elements are subjected to interactive deformation, so that the interactive deformation processing result is closer to the real situation.

Wherein the information of the central point is information for indicating the position of the central point in the model element, such as: the coordinates of the center point may be used, or vectors between the coordinates of each vertex and the corresponding coordinates of the center point may be used.

In one specific example, assume that a cluster of grass models includes multiple model elements. Each model element is a grass. The model element contains 5 vertices (A, B, C, D and E).

In an alternative embodiment of this embodiment, as shown in fig. 1b, the vertex diagram of a grass is shown, wherein the F point is taken as the only central point in the grass in the model element, and then the vectors AF, BF, CF, DF, and EF are the vectors from each vertex to the central point F.

In another alternative embodiment of this example, in FIG. 1c, a grass comprises 3 center points, specifically D, E and F. The vector from each vertex to the center point includes AF, BD, CE, DD, and EE. That is, in FIG. 1c, there is more than one center point, and each vertex can point to any one of the center points. In fig. 1b and 1c, the solid lines with arrows indicate the vectors from the respective vertices to the central point, and the dashed lines indicate the overall outline of a grass. In addition, the small circles in fig. 1c enclose D and E, which means that the vectors from D and E to the central point are both vectors pointing to themselves.

The vertex data may be stored in the UV data, vertex color data, instantiated array, tangent line, normal line or sub-tangent line data, and the like, which is not limited in this embodiment. Where a vertex may contain multiple sets of UV data, the center point data may be stored in a given set of UV data, i.e., UVn, where n represents the nth set of UV. The vertex color data includes R, G, B and a (brightness) four channels. An instantiated array is indexed by vertex ID or other int type variable associated with the vertex.

And S120, adjusting the vertex coordinates of each vertex according to the current interactive wind parameters and the information of the central point to obtain the vertex deformation coordinates of each vertex.

Wherein the interactive wind parameter refers to a wind parameter that other objects act on the model element in an interactive (contact or indirect contact) manner, and the interactive wind parameter may include: wind force and wind direction.

In this embodiment, in order to simulate the interaction between different objects, an interactive wind field may be constructed. For example, if a game character moves in a lawn, a force is theoretically applied to a surrounding set area around the game character, and the lawn in the area is squeezed. Based on the method, an interactive wind field can be generated by taking the game character as a center, and the interactive wind field can generate one or more interactive wind vectors for each point in the wind field, wherein the interactive wind vectors correspond to matched interactive wind parameters (wind power and wind direction). Correspondingly, the model elements which are also positioned in the area can carry out matched interactive wind deformation processing according to the received interactive wind parameters.

In this embodiment, the model elements are subjected to the wind exposure processing of the interactive wind on each vertex according to the information of the center point of the model element. The advantages of such an arrangement are: can make the model element when receiving mutual wind to produce deformation, build one kind and carry out the effect that receives the wind crooked around the central point, and can not be in disorder move everywhere, can guarantee the authenticity of model element when receiving mutual wind to take place deformation.

Optionally, the vertex coordinates of each vertex are adjusted according to the current interactive wind parameter and the information of the central point, and a manner of obtaining the vertex deformation coordinates of each vertex may be as follows:

aiming at each vertex, obtaining a vector between each vertex coordinate and the corresponding central point coordinate, and generating a wind vector corresponding to each vertex coordinate according to the interactive wind parameter; the vertex deformation coordinates corresponding to each vertex are calculated by the vector operation (vector addition or vector subtraction) of the two vectors.

Or, according to the wind power and the wind direction in the interactive wind parameter and a preset relational mapping table, a bending angle and a bending direction corresponding to each vertex are calculated, so that the vector between each vertex coordinate and the corresponding central point coordinate can be rotated according to the bending angle and the bending direction, and vertex deformation coordinates corresponding to each vertex are determined according to a new vector obtained after rotation.

Alternatively, an interactive wind bending function may be preset, where the interactive wind bending function takes the interactive wind parameter and the information of the center point as independent variables, and takes the vertex offset (in the XZ direction) as dependent variables. Based on the interactive wind bending function, vertex offset corresponding to each vertex can be calculated, and then vertex deformation coordinates of each vertex are calculated according to the vertex coordinates of each vertex and the vertex offset.

On the basis of the foregoing embodiments, the vertex data may further include: a softness factor for each vertex, the softness factor being associated with a location of the vertex in the model element;

correspondingly, adjusting the vertex coordinates of each vertex according to the current interactive wind parameters and the information of the central point to obtain vertex deformation coordinates of each vertex, which may include:

and adjusting the vertex coordinates of each vertex according to the current interactive wind parameters, the information of the central point and the softness factor of each vertex to obtain the vertex deformation coordinates of each vertex.

In this embodiment, different softness factors may be further stored for different vertices, and based on the softness factors, different portions of a single model element may have different deformation amplitudes. Typically, in a real scene that is subject to interactive deformation, the amplitude of deformation of the grass tip is the largest, and the amplitude of deformation is smaller when going downwards, so that the grass root is not deformed in general. In order to simulate the real scene in the game picture, the inventor creatively adds a softness factor (also called a wind influence factor) corresponding to each vertex in the vertex data.

The value range of the softness factor can be set to be [0, 1], and the larger the softness factor of a vertex is, the larger the deformation of the vertex after the vertex is subjected to the interactive wind is; the smaller the softness factor of a vertex is, the smaller the deformation of the vertex after being subjected to the interactive wind is, and when the softness factor of the vertex is 0, the vertex does not generate any deformation after being subjected to the interactive wind.

In a specific example, as shown in fig. 1B, the softness factor of vertex a may be set to 0.9, the softness factors of vertices B and C may be set to 0.5, and the softness factors of vertices D and E may be set to 0. At this time, even if only one center point F is set, the vertexes D and E of the grass root do not undergo any swing (deformation) after being subjected to the alternating wind because of the introduction of the softness factor.

The advantages of such an arrangement are: when each model element in the picture to be rendered is influenced by the interaction wind, the swinging (or deformation) amplitudes of different positions of the model element are different, and further the interaction deformation effect of the model element is closer to the real situation.

In an optional implementation manner of this embodiment, the vertex coordinates of each vertex are adjusted according to the current interactive wind parameter, the information of the central point, and the softness factor of each vertex, and a manner of obtaining the vertex deformation coordinates of each vertex is similar to the foregoing manner, for example, when a bending angle is calculated or an interactive wind bending function is constructed, the softness factor may be added as a new calculation reference item to ensure that the calculated vertex deformation coordinates of each vertex match the characteristics of the added calculated softness factor.

In the above optional implementation manner of this embodiment, the vertex data may further include: individual feature data for distinguishing the model element from other model elements of the same type.

and adjusting the vertex coordinates of each vertex according to the current interactive wind parameters, the information of the central point and the individual characteristic data to obtain the vertex deformation coordinates of each vertex.

The individual feature data may be a randomly generated random number, a number generated by calculation according to a certain rule, or a number set according to the characteristics of the object, and the same or different individual feature data may be set for each vertex of the same model element.

In the optional implementation manner of this embodiment, different individual feature data are set for different model elements, so that when a picture to be rendered includes a plurality of model elements of the same type (for example, a cluster of grass formed by a plurality of grass), the deformation of each model element after the interaction of the interaction wind is not completely the same, a relatively stiff display effect that each grass in the picture bends to the same angle in a certain direction after the interaction of the interaction wind is avoided, the interaction wind deformation of each model element can have a slight difference, and the picture is more natural without a sense of repetition.

In the above optional implementation manner of this embodiment, the vertex coordinates of each vertex are adjusted according to the current interactive wind parameter, the information of the central point, and the individual feature data, and the manner of obtaining the vertex deformation coordinates of each vertex is similar to the foregoing manner, for example, when a bending angle is calculated or an interactive wind bending function is constructed, the individual feature data may be added as a new calculation reference item to ensure that the vertex deformation coordinates of each vertex of different model elements obtained through calculation have a certain slight difference, so that the rendering picture presented finally is more actual in a real scene.

In an optional implementation manner of this embodiment, the vertex data may further include: softness factors and individual characteristic data of each vertex;

and adjusting the vertex coordinates of each vertex according to the current interactive wind parameters, the information of the central point, the softness factor of each vertex and the individual characteristic data to obtain the vertex deformation coordinates of each vertex.

In the above optional implementation manner of this embodiment, the softness factor and the individual characteristic data of each vertex are added at the same time to calculate the vertex deformation coordinates of each vertex after the model elements are subjected to the interaction wind, which not only ensures that when each model element in the picture to be rendered generates the interaction deformation, the deformation amplitudes of different positions of the model element are different, but also ensures that the vertex deformation coordinates of each vertex of different model elements have certain slight differences, further improves the display effect of the model element under the interaction wind, makes each model element in the picture to be rendered closer to the real interaction deformation effect, and improves the reality and interactivity of the picture.

Example two

Fig. 2 is a flowchart of a method for processing deformation of a model element in an embodiment of the present invention, which is refined based on the above embodiment, in this embodiment, vertex coordinates of each vertex are adjusted according to a current interactive wind parameter, information of the central point, a softness factor of each vertex, and the individual feature data, so as to obtain vertex deformation coordinates of each vertex, and the method is embodied as: calculating to obtain deformation offset corresponding to each vertex by taking the current interactive wind parameter, the information of the central point, the softness factor of each vertex and the individual characteristic data as weights; and obtaining the vertex deformation coordinate of each vertex according to the vertex coordinate of each vertex and the deformation offset corresponding to each vertex. Correspondingly, the method of the embodiment of the invention comprises the following steps:

and S210, extracting vertex data of the model elements.

Wherein the vertex data comprises: vertex coordinates of each vertex, information of a center point of the model element, softness factors of each vertex, and individual feature data.

S220, calculating to obtain deformation offset corresponding to each vertex by taking the current interactive wind parameter, the information of the central point, the softness factor of each vertex and the individual characteristic data as weights.

In this embodiment, an interactive wind bending function may be preset, where the interactive wind bending function takes an interactive wind parameter, information of a central point, a softness factor of a vertex, and the individual characteristic data as independent variables, and takes a vertex offset (in two XZ directions) as a dependent variable. Based on the interactive wind bending function, vertex offsets corresponding to each vertex can be calculated.

In one specific example, the interactive wind bending function may be set as:

wherein, X₀、Z₀The center point coordinate is determined according to the center point information, S is a softness factor of a vertex, Rand is individual characteristic data, and X_FAnd Z_FInteraction wind interaction coordinates determined according to the interaction wind parameters; specifically, the interactive wind vector may be determined with a set point (e.g., an origin of coordinates) as a starting point according to the wind force and the wind direction value in the interactive wind parameter, and coordinates of an end point of the interactive wind vector may be used as the interactive wind interaction coordinates.

By substituting the above items of information into the calculation for each vertex of the model element, vertex offsets corresponding to each vertex can be obtained, that is: Δ x and Δ z.

Of course, it can be understood that other interactive wind bending functions may be set according to actual conditions, as long as the set interactive wind bending functions can ensure that each parameter can play a role in the interactive wind bending functions according to the physical meaning thereof, and the embodiment of the present invention does not limit the specific form of the interactive wind bending functions.

And S230, obtaining vertex deformation coordinates of each vertex according to the vertex coordinates of each vertex and deformation offset corresponding to each vertex.

After the deformation offset of each vertex is obtained, the deformation offset and the corresponding vertex coordinate may be superimposed to obtain the vertex deformation coordinate of each vertex.

In one specific example, the following may be expressed in terms of the formula:

and calculating vertex deformation coordinates of each vertex.

Wherein (X, Z) is the vertex coordinate of each vertex, (X)_T，Z_T) The coordinates are deformed for each vertex's vertex.

EXAMPLE III

Fig. 3 is a flowchart of a method for processing deformation of a model element in a third embodiment of the present invention, which is refined based on the above embodiments, in this embodiment, vertex coordinates of each vertex are adjusted according to a current interactive wind parameter, information of the central point, a softness factor of each vertex, and the individual feature data, so as to obtain vertex deformation coordinates of each vertex, and the method is embodied as: calculating the bending angle and the bending direction of the target vertex relative to the central point according to the current interactive wind parameters, the softness factor of the target vertex currently processed in the model elements and the individual characteristic data; and acquiring a central point coordinate according to the information of the central point, and rotating the vertex coordinate of the target vertex by the bending angle along the bending direction by taking the central point coordinate as a rotating center to obtain a vertex deformation coordinate corresponding to the target vertex. Correspondingly, the method of the embodiment of the invention comprises the following steps:

and S310, extracting vertex data of the model elements.

S320, determining a currently processed target vertex in the model element, and acquiring softness factors of the target vertex and the individual characteristic data.

In this embodiment, for each vertex in the model element, a corresponding vertex deformation coordinate may be calculated.

S330, calculating the bending angle and the bending direction of the target vertex relative to the central point according to the current interactive wind parameters, the softness factor and the individual characteristic data.

In this embodiment, the matched interactive wind vector may be obtained according to the interactive wind parameters (wind speed and wind direction), and then the original bending angle and the original bending direction of the target vertex relative to the central point may be obtained by querying a preset mapping relationship table.

The mapping relationship among the wind vectors, the original bending angles and the original bending directions can be preset in the mapping relationship table, and after a specific interactive wind vector is obtained, the original bending angles and the original bending directions of the vertexes relative to the central point can be obtained by inquiring the mapping relationship table.

After obtaining the original bending angle and the original bending direction, the original bending angle and the original bending direction may be fine-tuned by using the softness factor and the individual characteristic data of the target vertex as weighting coefficients, so as to obtain the bending angle and the bending direction of the target vertex relative to the central point.

Alternatively, the bending angle and the bending direction of the target vertex relative to the central point may be obtained by multiplying only the original bending angle by the softness factor and the individual characteristic data of the target vertex, or by multiplying the original bending angle by the softness factor and the individual characteristic data of the target vertex, respectively, and the present embodiment is not limited thereto.

S340, obtaining a central point coordinate according to the information of the central point, and rotating the vertex coordinate of the target vertex by the bending angle along the bending direction by taking the central point coordinate as a rotation center to obtain a vertex deformation coordinate corresponding to the target vertex.

In this embodiment, after obtaining the bending angle and the bending direction of the target vertex relative to the central point, the vertex coordinates of the target vertex are controlled, the central point coordinates are used as the rotation center, the bending angle is rotated in the bending direction, and new vertex coordinates obtained through rotation are used as vertex deformation coordinates corresponding to the target vertex.

S350, judging whether the processing of all the vertexes in the model element is finished or not: if yes, ending the process; otherwise, return to execute S320.

Example four

Fig. 4a is a flowchart of a picture rendering method according to a fourth embodiment of the present invention, where this embodiment is applicable to a case of rendering and displaying a picture including model elements after interaction of wind, and the method may be executed by a picture rendering device, where the device may be implemented by software and/or hardware, and may be generally integrated in a terminal or a game server, and the method of this embodiment specifically includes the following steps:

and S410, acquiring at least one interactive wind field matched with the target picture when the interactive wind action display condition of the target picture is detected.

In this embodiment, in order to realize the display of the screen, it is necessary to first lay down various objects in a canvas using an object laying tool to form the screen under an environment of screen production (such as a game engine, digital content production software, and the like).

The object placement tool may be a brush tool, similar to a stamp of the shape of the object to be placed, where the placement of the object will stamp where. Specifically, when the mouse is in the screen creation environment and the object placement tool is activated, the screen creator may select a model of the object to be placed, and then the mouse may display the selected model on the screen creation interface in the shape of the selected model, and when the screen creator drags the mouse and clicks or performs other types of selection operations at a certain position in the target screen, the selected model is placed at the position. For example, a lot of grass is laid on a lawn to finally form the lawn, and generally, for the sake of picture making efficiency, the grass is laid in units of a cluster of grass models, and a cluster of grass is composed of a certain number of grass.

And when the picture is manufactured or previewed in the manufacturing process, the picture can be rendered and displayed, a shader is required to be called in the process, the display parameters of each model element in each laid object model are read through the shader, the picture is rendered according to the read display parameters, and the rendered picture is finally formed and displayed.

In this embodiment, if the display effect after the interaction of the interactive wind needs to be displayed in the current picture to be rendered, it is determined that the picture is a target picture meeting the display condition of the interaction of the interactive wind, and before the target picture is rendered and displayed by using the shader, at least one interactive wind field acting on the target picture needs to be acquired first.

It is understood that the target frame may include one or more dynamic objects, each dynamic object may generate an interactive wind field within a set range (e.g., a circular range, a rectangular range, or the like) centered on the dynamic object, and the interactive wind fields generated by different dynamic objects may not overlap with each other or have a certain overlapping area.

Wherein one or more interactive wind vectors are included in each interactive wind farm. The different interactive wind vectors correspond to different interactive wind parameters, and specifically, the interactive wind parameters may include a wind speed and a wind direction. Each interactive wind vector corresponds to a set region range in the interactive wind field.

Fig. 4b is an exemplary view of an interactive wind field to which the embodiment of the present invention is applicable, and as shown in fig. 4b, a dynamic object is located at a center position of the interactive wind field, the interactive wind field generated by the dynamic object acts in a rectangular area, and each area range in the rectangular area corresponds to an interactive wind vector.

And S420, acquiring at least one target model element to be processed by interactive wind and interactive wind parameters corresponding to the target model elements in the target picture according to the interactive wind fields.

As described above, only the model elements included in the action region of the interactive wind field may be subjected to interactive deformation, and therefore, the model elements in the operation region in the target screen need to be first acquired as the candidate model elements according to the action region of each interactive wind field.

Meanwhile, since the objects laid in each screen to be rendered and displayed are known and not all the objects need to be subjected to the interactive wind deformation processing, for example, when a screen includes trees, grass, stones and houses, it is obvious that each grass in the leaves and grass of trees needs to be subjected to the interactive wind deformation processing, and the stones and houses do not need to be subjected to the interactive wind deformation processing.

Correspondingly, after the candidate model elements are obtained, at least one target model element needing interactive wind processing can be determined according to the type of each candidate model element.

After obtaining each target model element, the interactive wind vectors of one or more interactive wind fields acting on the target model element may be further determined, for example, if two interactive wind fields act on one target model element at the same time, a first interactive wind vector and a second interactive wind vector corresponding to the target model element may be obtained respectively, and the first interactive wind vector and the second interactive wind vector may be superimposed to obtain an interactive wind parameter corresponding to the target model element.

S430, obtaining vertex deformation coordinates of each vertex in each target model element by adopting the deformation processing method of the model elements according to any embodiment of the invention.

After obtaining each target model element in the target picture, the model element deformation processing method according to any embodiment of the present invention may obtain a new vertex deformation coordinate formed by each target model element after the interactive wind processing according to the vertex data of each target model element and the current interactive wind parameter.

S440, rendering and displaying each target model element according to the vertex deformation coordinates of each vertex in each target model element.

And finally, rendering the target picture by the shader according to the new vertex deformation coordinates of each target model element, and finally displaying the rendering result on a screen.

The technical scheme of the embodiment of the invention obtains at least one interactive wind field matched with the target picture when the interactive wind action display condition of the target picture is detected; according to each interactive wind field, at least one target model element to be processed by interactive wind and interactive wind parameters respectively corresponding to each target model element are obtained in the target picture; obtaining vertex deformation coordinates of each vertex in each target model element by adopting a model element deformation processing method; according to the technical scheme of rendering and displaying each target model element according to the vertex deformation coordinates of each vertex in each target model element, when the model element to be rendered and displayed is subjected to deformation processing, each vertex of the model element is controlled to carry out deformation processing around the central point of the model element, so that a new model element obtained after rendering is closer to an actual interactive deformation effect.

Fig. 5 is a flowchart of a picture rendering method in a fifth embodiment of the present invention, which is refined based on the above embodiment, in this embodiment, the operation of obtaining, according to each interactive wind field, at least one target model element to be processed by interactive wind and an interactive wind parameter respectively corresponding to each target model element in the target picture is specifically as follows: acquiring at least one target model element to be processed by interactive wind in the target picture according to the action area of each interactive wind field; sequentially acquiring a target model element as a current processing element; acquiring at least one target interactive wind field of which the action area covers the current processing element, and respectively sampling interactive wind vectors corresponding to the current processing element in each target interactive wind field; and obtaining interactive wind parameters corresponding to the current processing element according to the interactive wind vectors obtained by sampling, and returning to execute the processing of sequentially obtaining one target model element as the current processing element until the processing of all the target model elements is completed. Correspondingly, the method of the embodiment of the invention comprises the following steps:

and S510, acquiring at least one interactive wind field matched with the target picture when the interactive wind action display condition of the target picture is detected.

S520, acquiring at least one target model element to be processed by the interactive wind in the target picture according to the action area of each interactive wind field.

As described above, each interactive wind field corresponds to an action region with a set shape (a circle or a matrix, etc.), and at least one target model element that needs to be processed by the interactive wind may be determined in the target screen according to the action region of each interactive wind field and the type of each model element in the target screen (for whether the interactive deformation occurs).
