[0052] After research, it was found that shield effects are often needed in games to present some of the character's striking actions. The current shield effect is a static effect, so the effect is poor.

[0053] The shield of the traditional model is a static effect when it is modeled and cannot achieve dynamic changes. The traditional shield effect often needs to be combined with animation to present a dynamic effect. Therefore, it is costly to display a dynamic shield effect based on a transmission model.

[0057] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of the electronic device 100 provided in the embodiment of the present application. The electronic device 100 may also include Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0059] The electronic device may also include at least one network interface and a user interface. The various components in the electronic device 100 are coupled together via a bus system. It is understood that the bus system is used to achieve connection and communication between these components. In addition to the data bus, the bus system also includes a power bus, a control bus, and a status signal bus.

[0060] The components of the memory 120 and the processor 130 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The vertex adjustment device 110 includes at least one software function module that can be stored in the memory 120 in the form of software or firmware or solidified in the operating system (OS) of the electronic device 100.

[0065] Please refer to Figure 2 , Figure 2 For application Figure 1 A flowchart of a vertex adjustment method of an electronic device 100 is provided, and the method including each step is described in detail below.

[0066] S201: Determine a normal vector of a model space to be processed, and convert the normal vector into a view space normal.

[0067] S202: Determine vertex UV coordinates and vertex normals of the mesh in the model space to be processed.

[0068] UV coordinates are a two-dimensional coordinate system used to describe texture mapping information on the surface of a model. Each vertex has a corresponding UV coordinate that is used to determine the position of the vertex in the texture image. The range of UV coordinates is usually from (0,0) to (1,1), with the upper left corner being (0,0) and the lower right corner being (1,1). UV coordinates are used to sample the texture and map it onto the surface of the model, thereby achieving texture mapping and rendering.

[0069] S203: Generate time-based noise, UV-based noise, and normal-based noise based on current time parameters, vertex UV coordinates, and vertex normals.

[0070] S204: Determine the vertex offset of the model space to be processed based on the view space normal, time-based noise, UV-based noise, and normal-based noise.

[0071] S205: Adjusting the vertex positions of the model space to be processed based on the vertex offsets.

[0072] It should be noted that the model space to be processed can be a virtual object in a virtual scene. A virtual scene is a virtual scene displayed (or provided) when an application is running on a terminal. The virtual scene can be a simulation environment of the real world, a semi-simulation and semi-fictitious virtual environment, or a purely fictitious virtual environment. The virtual scene can be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene, or a three-dimensional virtual scene. The embodiment of the present application does not limit the dimension of the virtual scene.

[0073] For example, when the virtual scene is a three-dimensional virtual space, the three-dimensional virtual space can be an open space. The virtual scene can be used to simulate the real environment in reality. For example, the virtual scene can include the sky, land, ocean, etc., and the land can include environmental elements such as deserts and cities. Of course, the virtual scene can also include virtual items, such as buildings, vehicles, and weapons and other props used by virtual objects in the virtual scene to arm themselves or fight with other virtual objects. The virtual scene can also be used to simulate the real environment under different weather conditions, such as sunny days, rainy days, foggy days, or night weather. Users can control virtual objects to move in the virtual scene.

[0074] Virtual objects are images of various people and objects that can interact in a virtual scene, or movable objects in a virtual scene. The movable objects can be virtual characters, virtual animals, cartoon characters, etc., such as characters displayed in a virtual scene. The virtual object can be a virtual image in the virtual scene that represents the user. A virtual scene can include multiple virtual objects, each of which has its own shape and volume in the virtual scene and occupies a part of the space in the virtual scene.

[0075] The virtual object may be a user character controlled by operations on the client, or an artificial intelligence (AI) set in a virtual scene battle through training, or a non-user character (NPC) set in a virtual scene interaction. Optionally, the virtual object may be a virtual character that performs adversarial interaction in the virtual scene. Optionally, the number of virtual objects participating in the interaction in the virtual scene may be pre-set or dynamically determined according to the number of clients joining the interaction.

[0076] The normal vector in the model space to be processed is a vector defined in the object's own coordinate system, which describes the perpendicular direction of the tangent plane at each point on the model surface. Normal vectors are crucial for lighting calculations because they determine how the surface interacts with the incident light, which in turn affects the color and brightness of the rendering.

[0077] The model space normal vectors to be processed are defined relative to the origin and coordinate axes of the model itself, without any transformation. This means that if the model is rotated or moved, the model space normal vectors remain unchanged and only represent the inherent geometric direction of the model. The model space normal vectors can usually be directly derived from the 3D modeling software, or calculated through geometric algorithms such as plane equations, cross products of polygonal faces, etc. Before performing lighting calculations, the model space normal vectors often need to be converted to other spaces (such as world space, view space) in order to correctly match the light source position and the observer's perspective. But in the original model data, they remain in model space expression. Regardless of the space, the normal vector needs to be kept as a unit vector, that is, the length is 1, in order to ensure the accuracy of the lighting calculation.

[0078] The view space normal refers to the normal vector in the model space to be processed converted to the view space coordinate system. It enables the lighting calculation to be centered on the observer's perspective, thereby improving efficiency and effect.

[0079] The specific implementation method of converting the normal vector into the view space normal may be: determining the normal vector of the model space to be processed and the view projection matrix, and calculating the product of the normal vector and the view projection matrix as the view space normal.

[0080] The view-projection matrix combines the functions of the view matrix and the projection matrix to transform the 3D scene from the model space to the 2D pixel coordinates visible on the screen. The transformation process is divided into two steps: 1. View transformation: The view matrix transforms the world space into the observation space (also called view space), which is achieved by simulating a coordinate system fixed to the position and orientation of the camera. This means that all calculations are performed relative to the camera. 2. Projection transformation: The projection matrix further transforms the view space into the clipping space, which determines the visible range, perspective effect, or orthographic projection size of the final image. In the clipping space, vertices within a specific range (usually between -1 and 1) are mapped to the screen, while vertices outside the range are clipped. In summary, the view-projection matrix implements a complete transformation from 3D space to 2D screen coordinates.

[0081] The view space normal is finally normalized so that its final vector length is 1, ensuring that the view space normal is still a unit vector.

[0082] Divide the model space to be processed into square grids (2D) or cubic grids (3D), that is, grids, and determine the vertex UV coordinates corresponding to each grid and the vertex normals of each grid.

[0083] Generates time-based noise, UV-based noise, and normal-based noise based on the current time parameters, vertex UV coordinates, and vertex normals.

[0084] Time-based noise is a random signal or disturbance that changes over time. It is often used in computer graphics, audio processing, physical simulation and other fields to increase dynamic realism or simulate uncertainty in natural phenomena. The characteristic of this type of noise is that its value changes over time, providing a dynamic change effect, which is different from a static noise pattern. UV-based noise refers to the noise pattern generated or applied according to the sampling points on the UV coordinates of the model surface in texture mapping. This noise is different from traditional noise based on spatial coordinates or time changes. Its changes depend on texture coordinates, so that the noise pattern can be attached to the surface of the 3D model along with the texture. Normal-based noise involves applying noise perturbations to the surface normals of a 3D model to achieve more natural or complex surface details and lighting effects. Normal-based noise affects the geometric appearance and lighting interaction of the model space to be processed.

[0085] Finally, based on the view space normal, time base noise, UV base noise and normal base noise obtained above, the vertex offset of the model space to be processed is determined, and the vertex position of the model space to be processed is adjusted based on the vertex offset. Thus, the position of the vertex in the model space to be processed is changed in real time, so as to realize the dynamic performance of the shield, that is, to change the presentation mode of the shield of the virtual object in the virtual scene.

[0086] There are many ways to generate time-based noise, UV-based noise and normal-based noise based on the current time parameters, vertex UV coordinates and vertex normals. In one implementation, Figure 3 As shown, the following steps are included:

[0087] S301: Generate time-based noise and UV-based noise based on current time parameters and vertex UV coordinates.

[0088] S302: Generate normal-based noise based on the current time parameter and the vertex normal.

[0089] Use the snoise function to generate time-based noise and UV-based noise based on the current time parameters and vertex UV coordinates.

[0090] Generates normal-based noise using the current time parameters and vertex normals as input to the snoise function. The noise value of the normal-based noise will produce different noise as the normal changes.

[0091] There are many ways to determine the vertex offset of the model space to be processed based on the view space normal, time base noise, UV base noise and normal base noise. In one implementation, Figure 4 As shown, the following steps are included:

[0092] S401: Calculate a first product of the time-based noise and the UV-based noise.

[0093] S402: Determine a first sinusoidal function value of the first product.

[0094] S403: Obtain a first target sine function value within a preset range from the first sine function values.

[0095] S404: Determine a first vertex offset in the model space to be processed based on the first target sine function value and the view space normal.

[0096] The time-based noise obtained in the present invention produces changes on the entire object, while the UV-based noise produces different noise values ​​at different positions on the surface of the object. The time-based noise and the UV-based noise are combined to adjust the vertex positions of the model space to be processed.

[0097] The first sine function value of the first product of the time-based noise and the UV-based noise is determined, and the first sine function value is limited according to a preset range, so as to realize the control of the combination of the time-based noise and the UV-based noise.

[0098] It should be noted that the preset range can be set according to actual conditions, and the embodiment of the present invention does not impose specific restrictions on this. The setting of the preset range achieves the effect of zooming in or out of the subsequent vertex offset along the sine wave.

[0099] The first vertex offset can be calculated using the following formula:

[0100] offset1=normalviev.xy*norLen1*offsetScale;

[0101] Among them, offset1 is the first vertex offset, normalviev.xy is the view space normal, norLen1 is the first target sine function value, and offsetScale is the first scaling factor.

[0102] It should be noted that the first scaling factor can be set according to actual conditions, and the embodiment of the present invention does not impose any specific limitation on this. Specifically, the first scaling factor can be obtained from a general register.

[0103] There are many ways to determine the vertex offset of the model space to be processed based on the view space normal, time base noise, UV base noise and normal base noise. In one implementation, Figure 5 As shown, the following steps are included:

[0104] S501: Determine a second sine function value of the vertex normal.

[0105] S502: Calculate the second sine function value and the current time parameter to obtain a normal disturbance value.

[0106] S503: Determine a second vertex offset of the to-be-processed model space based on the normal disturbance value and the view space normal.

[0107] The normal perturbation value is calculated by the following formula:

[0108] norLen2=sin(snoise(normal)*Time*NoiseScale)+0.8) / 2.0;

[0109] Among them, norLen2 is the normal disturbance value, snoise(normal) is the second sine function value, Time is the current time parameter, and NoiseScale is the second scaling factor.

[0110] The normal perturbation value realizes the dynamic perturbation of the length and direction of the normal, simulating the deformation effect of the shield under the action of external force.

[0111] The second vertex offset is calculated using the following formula:

[0112] offset2=normalviev.xy*norLen2*offsetScale;

[0113] Among them, offset2 is the second vertex offset, normalviev.xy is the view space normal, norLen2 is the normal perturbation value, and offsetScale is the first scaling factor.

[0114] When the vertex position of the processed model space is finally adjusted, it can be adjusted based on the first vertex offset or the second vertex offset. Finally, the first vertex offset or the second vertex offset is applied to the output vertex clip coordinates, thereby achieving a dynamic expansion effect on the shield surface.

[0115] Please refer to Figure 6 The present application embodiment also provides a method for applying Figure 1 The vertex adjustment device 110 of the electronic device 100 includes:
