[0034] Embodiment 1

[0035] Figure 1a This is a flow chart of a deformation processing method for a model element provided in the first embodiment of the present invention. This embodiment is applicable to the case where a small object in a virtual scene is subjected to breeze vibration processing. The method can be executed by a deformation processing device for a model element. The device can be implemented by software and / or hardware and can generally be integrated in a terminal or a server (typically, a game server). The method of this embodiment specifically includes the following steps:

[0036] S110 . Extract vertex data of a model element, wherein the vertex data includes vertex coordinates of each vertex and information of a center point of the model element.

[0037] In this embodiment, the model element refers to a specific individual element among a large number of small objects laid out in the picture to be rendered and displayed. For example, the model element can be a flower in a sea of ​​flowers, a blade of grass in a clump of grass on a lawn, or a leaf on a tree.

[0038] In this embodiment, each model element has a preset number of vertices (generally multiple), wherein 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 the center point of the model element.

[0039] Among them, after connecting the vertex coordinates of each vertex in sequence, the contour shape of the model element can be obtained.

[0040] Generally speaking, a model element may include one or more center points, which are generally located at the root of the model element close to the ground. After setting the center point, when the model element is deformed by breeze vibration, the root will not vibrate, so that the result of the vibration deformation processing is closer to the real situation.

[0041] The information of the center point is information used to indicate the position of the center point in the model element, for example, it may be the center point coordinates, or it may be a vector between the coordinates of each vertex and the corresponding center point coordinates.

[0042] In a specific example, it is assumed that a model of a tuft of grass includes multiple model elements. Each model element is a blade of grass. The model element includes five vertices (A, B, C, D, and E).

[0043] In an optional implementation of this embodiment, Figure 1b The diagram of the vertices of a blade of grass is shown in , where point F is taken as the only center point of the blade of grass in the model element, and vectors AF, BF, CF, DF and EF are the vectors from each vertex to the center point F.

[0044] In another optional implementation of this embodiment, Figure 1c In the example, a grass bag has three center points, namely D, E and F. The vectors from each vertex to the center point include AF, BD, CE, DD and EE. In other words, Figure 1c In , there is more than one center point, and each vertex can point to any of the center points. Figure 1b and Figure 1c In the figure, the solid lines with arrows represent the vectors from each vertex to the center point, and the dotted lines represent the overall outline of a blade of grass. Figure 1c The small and medium circles around D and E indicate that the vectors from D and E to the center point are both pointing to themselves.

[0045] The above vertex data can be stored in UV data, vertex color data, instantiated arrays, tangents, normals or bitangent data locations, etc., and this embodiment does not limit this. A vertex may contain multiple sets of UV data, and the center point data can be stored in a specified set of UV data, that is, UVn, where n represents the nth set of UV. Vertex color data includes four channels: R, G, B and A (brightness). An instantiated array is an array indexed by a vertex ID or other int type variable related to a vertex.

[0046] S120 , generating a vibration deformation function of each vertex according to the information of the central point, wherein the vibration deformation function is a time function.

[0047] In this embodiment, in order to simulate the model element trembling in the breeze, a trembling deformation function corresponding to each vertex can be constructed. The above trembling deformation function can be expressed as: at different times, a certain fixed point is used as the center, and the left and right vibrations are performed (that is, the trembling display effect). Based on the vertex coordinate deformation formed by the trembling deformation function, the animation effect of the model element trembling slightly with the breeze can be simulated at multiple continuous times.

[0048] In this embodiment, the advantage of generating the vibration deformation function of each vertex based on the information of the center point is that it can create an effect of slight left and right swinging around the center point when the model element undergoes vibration deformation, instead of moving around randomly, thereby ensuring the authenticity of the model element shaking with the breeze.

[0049] Generally speaking, the sine function or cosine function is a function used to simulate simple harmonic vibration, and the simple harmonic vibration is very close to the vibration of the model element in the embodiment of the present invention under the breeze. Therefore, a standard sine or cosine function can be constructed in advance, and the amplitude, frequency and phase of the sine or cosine function can be set according to the preset parameters. Furthermore, the coordinates of the center point corresponding to each vertex can be determined according to the information of the center point, and then the coordinates of each center point are used as the oscillation center, and the vibration deformation function of each vertex is set to achieve that each vertex can oscillate with the matching center point as the center at different times.

[0050] Of course, it is understandable that those skilled in the art can also construct other types of trembling deformation functions, as long as the trembling deformation function used can enable each vertex in the model element to use the corresponding center point as the trembling center and tremble left and right around the center point. This embodiment does not limit the specific form of the trembling deformation function.

[0051] S130 , adjusting the vertex coordinates of each vertex according to the current time and the tremor deformation function of each vertex to obtain the vertex deformation coordinates of each vertex.

[0052] In this embodiment, the jitter deformation function is a function of time. By substituting the values ​​at different times into the jitter deformation function, the deformation offsets (XZ values) of different vertex coordinates can be obtained. The calculated deformation offsets of the vertex coordinates are superimposed with the corresponding vertex coordinates to obtain the vertex deformation coordinates of each vertex.

[0053] The technical solution of the embodiment of the present invention extracts vertex data of the model element; generates a trembling deformation function of each vertex according to the information of the center point; adjusts the vertex coordinates of each vertex according to the current time and the trembling deformation function of each vertex, and obtains the vertex deformation coordinates of each vertex. When the model element is subjected to trembling deformation processing, each vertex of the model element is controlled to perform trembling deformation processing around the center point of the model element, so that the new model element obtained after rendering is closer to the actual breeze trembling effect. The technical solution of the embodiment of the present invention provides a deformation processing method for simulating the trembling of the model element in the breeze, optimizes the display effect of the model element, and further improves the authenticity of the displayed picture.

[0054] On the basis of the above embodiments, the vertex data may further include: a softness factor of each vertex, the softness factor being associated with the position of the vertex in the model element;

[0055] Correspondingly, generating the trembling deformation function of each vertex according to the information of the center point may include:

[0056] A vibration deformation function of each vertex is generated according to the information of the central point and the softness factor of each vertex.

[0057] In this embodiment, different softness factors can be further stored for different vertices. Based on the softness factors, different parts of a single model element can have different vibration amplitudes. Typically, in a scene where a blade of grass vibrates in a real breeze, the tip of the grass vibrates the most, and the amplitude of the vibration decreases as it goes down. Grass roots generally do not vibrate. In order to simulate the above real scene in the game screen, the inventor creatively adds a softness factor (also called a wind-affected factor) corresponding to each vertex in the vertex data.

[0058] The value range of the softness factor can be set to [0, 1], and it is stipulated that the larger the softness factor of a vertex is, the greater the deformation of the vertex when it vibrates with the breeze; the smaller the softness factor of a vertex is, the smaller the deformation of the vertex when it vibrates with the breeze. When the softness factor of a vertex is 0, the vertex will not produce any deformation after the breeze blows.

[0059] In a specific example, Figure 1b As shown, the softness factor of vertex A can be set to 0.9, the softness factors of vertices B and C can be set to 0.5, and the softness factors of vertices D and E can be set to 0. At this time, even if only one center point F is set, due to the introduction of the softness factor, in the scene of simulating breeze blowing, the vertices D and E at the root of the grass will not vibrate at all.

[0060] The advantage of this setting is that when each model element in the picture to be rendered vibrates in the breeze, the vibration (or deformation) amplitude of different positions of the model element is different, thereby making the effect of the model element vibrating with the breeze closer to the real situation.

[0061] In an optional implementation of the present embodiment, when generating the vibration deformation function of each vertex based on the information of the center point and the softness factor of each vertex, since it is necessary to ensure that the vibration amplitudes of vertices in different positions are different, the softness factor of the vertex can be used to set the vibration amplitude of the vibration deformation function.

[0062] For example, for a standard sine or cosine function, the softness factor of each vertex can be used as the amplitude of the standard sine or cosine function, or the softness factor can be used to correct the amplitude of the standard sine or cosine function to ensure that the calculated vertex deformation coordinates of each vertex match the characteristics of the calculated softness factor.

[0063] In the above optional implementation of this embodiment, the vertex data may further include: individual feature data, and the individual feature data is used to distinguish the model element from other model elements of the same type.

[0064] Correspondingly, generating the trembling deformation function of each vertex according to the information of the center point may include:

[0065] A tremor deformation function of each vertex is generated according to the information of the center point and the individual feature data.

[0066] The individual feature data may be a random value generated randomly, or a value calculated according to certain rules, or a value set according to the characteristics of the object. The same or different individual feature data may be set for each vertex of the same model element.

[0067] In an optional implementation of the present embodiment, by setting different individual feature data for different model elements, it can be achieved that when the picture to be rendered includes multiple model elements of the same type (for example, a cluster of grass composed of multiple grasses), the vibrating deformation of each model element is not exactly the same, so as to avoid the rather stiff display effect that each grass in the picture vibrates in a certain direction with the same displacement when vibrating and deforming. The vibrating effect of each model element can have slight differences, thereby making the picture more natural and without repetition.

[0068] In the above optional implementation of the present embodiment, when generating the jitter deformation function of each vertex according to the information of the center point and the individual feature data, since it is necessary to ensure that the jitter amplitudes of vertices in different positions will have slight differences, the individual feature data can be used to set the frequency or phase of the jitter deformation function. For example, for a standard sine or cosine function, the individual feature data can be used as the phase of the standard sine or cosine function, or the individual feature data can be used to correct the phase of the standard sine or cosine function to ensure that the calculated vertex deformation coordinates of each vertex of different model elements will have certain slight differences, so that the final rendered picture is more realistic than the actual situation in the scene.

[0069] In an optional implementation of this embodiment, the vertex data may also include: the softness factor and individual characteristic data of each vertex;

[0070] Correspondingly, generating the trembling deformation function of each vertex according to the information of the center point may include:

[0071] A vibration deformation function of each vertex is generated according to the information of the central point, the softness factor of each vertex and the individual characteristic data.

[0072] In the above optional implementation of the present embodiment, the softness factor of each vertex and the individual characteristic data are added to calculate the vertex deformation coordinates of each vertex when the model element vibrates, which ensures that each model element in the picture to be rendered has different vibration amplitudes at different positions when simulating breeze vibration, and also ensures that the vertex deformation coordinates of each vertex of different model elements will have certain slight differences, further improving the vibration display effect of the model element, making each model element in the picture to be rendered closer to the real breeze vibration effect, and improving the authenticity and interactivity of the picture.

[0073] Embodiment 2

[0074] Figure 2 It is a flow chart of a deformation processing method of a model element in the second embodiment of the present invention. This embodiment is refined on the basis of the above embodiment. In this embodiment, a jitter deformation function of each vertex is generated according to the information of the center point, the softness factor of each vertex and the individual feature data. Specifically, a standard jitter function is obtained, and the standard jitter function includes: multiple parameters to be filled in; the information of the center point, the softness factor of each vertex and the individual feature data are filled into the standard jitter function to obtain the jitter deformation function of each vertex.

[0075] At the same time, the vertex coordinates of each vertex are adjusted according to the current time and the jitter deformation function of each vertex to obtain the vertex deformation coordinates of each vertex, which is specifically: according to the current time and the jitter deformation function of each vertex, the deformation offset of each vertex is calculated; according to the vertex coordinates of each vertex and the deformation offset corresponding to each vertex, the vertex deformation coordinates of each vertex are obtained.

[0076] Accordingly, the method of the embodiment of the present invention includes:

[0077] S210: Extract vertex data of model elements.

[0078] The vertex data includes: vertex coordinates of each vertex, information of the center point of the model element, a softness factor of each vertex and the individual feature data.

[0079] S220: Acquire a standard dither function, where the standard dither function includes: a plurality of parameters to be filled.

[0080] Optionally, the standard dither function may be a sine function. For example, a standard dither function of the form: sin(t)=A0+A*sin(ωt+θ) may be constructed.

[0081] Among them, t is the independent variable in the standard dither function, ω is the preset dither frequency value, A0, A and θ are parameters to be filled in, and after obtaining the vertex data of each vertex, they can be filled in the standard dither function as parameters.

[0082] Of course, the above only shows an optional form of a standard dither function. In fact, those skilled in the art may preset the standard dither function and the various parameters to be filled in the standard dither function according to actual conditions, and this embodiment does not limit this.

[0083] S230, filling the information of the center point, the softness factor of each vertex and the individual characteristic data into the standard tremor function to obtain the tremor deformation function of each vertex.

[0084] Based on the information of the center point of each vertex, the center point coordinates corresponding to each vertex can be obtained (the center point coordinates corresponding to different vertices can be the same or different). After obtaining the above-mentioned standard jitter function, the center point coordinates corresponding to each vertex, the softness factor of each vertex, and the above-mentioned individual feature data (the individual feature data corresponding to different vertices can be the same or different) can be filled in the standard jitter function to obtain the jitter deformation function of each vertex.

[0085] Continuing with the previous example, the coordinates of the center point can be filled in the position of the parameter A0 to be filled in the standard jitter function, the softness factor can be filled in the position of the parameter A to be filled, and the individual feature data can be filled in the position of the parameter θ to be filled, so as to obtain the jitter deformation function of each vertex.

[0086] S240: Calculate the deformation offset of each vertex according to the current time and the vibration deformation function of each vertex.

[0087] Optionally, you can use the formula: Substitute the current time and calculate the deformation offset Δx and Δz of each vertex.

[0088] Among them, X0 and Z0 are the coordinates of the center point, S is the softness factor of the vertex, and Rand is the individual characteristic data.

[0089] S250 , obtaining vertex deformation coordinates of each vertex according to the vertex coordinates of each vertex and the deformation offsets respectively corresponding to each vertex.

[0090] After the deformation offset of each vertex is obtained, the deformation offset and the corresponding vertex coordinates may be superimposed to obtain the vertex deformation coordinates of each vertex.

[0091] In a specific example, the formula: Calculate the vertex deformation coordinates of each vertex.

[0092] Among them, (X, Z) is the vertex coordinates of each vertex, (X T , Z T ) is the vertex deformation coordinate of each vertex.

[0093] The technical solution of the embodiment of the present invention extracts vertex data of the model element; generates a trembling deformation function of each vertex according to the information of the center point; adjusts the vertex coordinates of each vertex according to the current time and the trembling deformation function of each vertex, and obtains the vertex deformation coordinates of each vertex. When the model element is subjected to trembling deformation processing, each vertex of the model element is controlled to perform trembling deformation processing around the center point of the model element, so that the new model element obtained after rendering is closer to the actual breeze trembling effect. The technical solution of the embodiment of the present invention provides a deformation processing method for simulating the trembling of the model element in the breeze, optimizes the display effect of the model element, and further improves the authenticity of the displayed picture.

[0094] Embodiment 3

[0095] Figure 3This is a flowchart of a screen rendering method provided in Embodiment 3 of the present invention. This embodiment is applicable to the case where a screen including a model element after trembling processing is rendered and displayed. The method can be executed by a screen rendering device, which can be implemented by software and / or hardware and can generally be integrated in a terminal or a game server. The method of this embodiment specifically includes the following steps:

[0096] S310 . Whenever a trembling display condition of a target picture is detected, obtain the current time, and obtain at least one target model element to be trembling processed in the target picture.

[0097] In this embodiment, in order to realize the rendering display of the picture, it is necessary to first use the object laying tool to lay out various objects on the canvas in the picture production environment (such as a game engine, digital content production software, etc.) to form a picture.

[0098] The object laying tool can be a brush tool, similar to a stamp in the shape of the object to be laid, and the stamp will be placed where the object is laid. Specifically, when the mouse is in the picture making environment and the object laying tool is activated, the picture maker can select the model of the object to be laid, then the mouse can be displayed in the shape of the selected model on the picture making interface, and when the picture maker drags the mouse and clicks or performs other forms of selection operations at a certain position in the target picture, the selected model is laid at that position. For example, a large amount of grass is laid on a lawn to eventually form a lawn. Usually, for the sake of picture making efficiency, the grass is laid in units of a tuft of grass model during the laying process, and a tuft of grass is composed of a certain number of grass roots.

[0099] When the picture is completed or previewed during the production process, it can be rendered and displayed. This process requires calling the shader, which reads the display parameters of each model element in each laid object model, and renders the picture according to the read display parameters, finally forming and displaying the rendered picture.

[0100] In this embodiment, if the current picture to be rendered needs to show the display effect of each model element after the breeze blows, the picture is determined to be a target picture that meets the shaking display conditions. At this time, there is no need to actually simulate the wind force, wind direction and other information of the breeze. Only the model elements that need to shake slightly with the breeze need to be subjected to shaking deformation processing.

[0101] As mentioned above, the objects laid out in each picture to be rendered and displayed are known, and not all objects need to be vibrated and deformed. For example, when a picture includes trees, grass, stones and houses, it is obvious that the leaves in the trees and each blade of grass in the grass need to be vibrated and deformed, while the stones and houses do not need to be vibrated and deformed.

[0102] Accordingly, at least one target model element in the target picture that needs to be subjected to a trembling deformation process may be determined first.

[0103] S320: Using the deformation processing method of the model element as described in any embodiment of the present invention, obtain the vertex deformation coordinates of each vertex in each target model element.

[0104] After acquiring each target model element in the target image, the deformation processing method of the model element described in any embodiment of the present invention can be used to obtain new vertex deformation coordinates of each target model element after the trembling deformation processing according to the vertex data of each target model element and the current time.

[0105] S330 , rendering and displaying each of the target model elements according to the vertex deformation coordinates of each vertex in each of the target model elements.

[0106] Finally, the shader renders the target image according to the new vertex deformation coordinates of each target model element, and finally displays the rendering result on the screen.

[0107] The technical solution of the embodiment of the present invention obtains the current time whenever the shaking display condition of the target picture is detected, and obtains at least one target model element to be shaken in the target picture, adopts the deformation processing method of the model element, and obtains the vertex deformation coordinates of each vertex in each target model element; according to the vertex deformation coordinates of each vertex in each target model element, the technical solution of rendering and displaying each target model element can control the vertices of the model element to perform shaking deformation processing around the center point of the model element when the model element is subjected to shaking deformation processing, so that the new model element obtained after rendering is closer to the actual breeze shaking effect. The technical solution of the embodiment of the present invention provides a deformation processing method for simulating the shaking of model elements in the breeze, optimizes the display effect of the model elements, and further improves the authenticity of the displayed picture.
