[0037] Please refer to Figure 1 , Figure 1 Schematic diagram of an application environment of the texture rendering method provided by an embodiment of the present invention. Figure 1 As shown, the terminal device 10 is in communication connection with the server 20 , wherein there are one or more terminal devices 10 , which is not limited in the embodiment of the present invention.

[0038] In this embodiment, the server 20 stores textures and rendering files that can be used by the terminal device 10 to achieve ablation effects.

[0039] In this embodiment, the terminal device 10 may be a personal computer (PC), a laptop computer, a tablet computer, a mobile phone, etc., and the embodiment of the present invention does not limit this.

[0040] Please refer to Figure 2 is a block diagram of a terminal device 10 provided in an embodiment of the present invention. The terminal device 10 includes a memory 210, a processor 220, and a communication module 230. The memory 210, processor 220, and communication module 230 are electrically connected to each other, directly or indirectly, to enable data transmission or exchange. For example, these components may be electrically connected via one or more communication buses or signal lines.

[0041] The memory 210 is used to store programs or data. The memory 210 can be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.

For example, when the processor 220 executes the computer program stored in the memory 210, the texture rendering method disclosed in various embodiments of the present invention can be implemented.

[0044] The communication module 230 is used to establish a communication connection between the terminal device 10 and the server 20 through the network, and to send and receive data through the network.

[0045] It should be understood that Figure 2 The structure shown is only a schematic diagram of the structure of the terminal device 10. The terminal device 10 may also include Figure 2 More or fewer components than shown, or with Figure 2 Different configurations shown. Figure 2 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0046] An embodiment of the present invention further provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the texture rendering method disclosed in each embodiment of the present invention can be implemented.

[0047] In the existing technology, the traditional method of achieving ablation effects in three-dimensional games is to make the three-dimensional model transparent through a mask map. However, when implementing the ablation effect for large models, the use of a separate mask map and the model map for interpolation will increase the processing time, and the processing time is borne by the user, which reduces the user experience; and the ablation effect requires two maps to be achieved, which increases resource waste.

[0048] Based on the above problems, in order to solve the problems of high processing time and high resource waste when realizing ablation special effects in the prior art, the embodiment of the present invention provides a texture rendering method, please refer to Figure 3 , Figure 3 A flowchart of a texture rendering method provided by an embodiment of the present invention. The method includes:

[0049] Step S301: In response to the user's operation on the terminal device, a target map and a target rendering file are obtained from the server.

[0050] Optionally, the operations of the responding user on the terminal device are not limited and can be selected according to actual needs. For example, taking a three-dimensional game as an example, when the user opens the three-dimensional game through the terminal device 10, the terminal device 10 will send version query information to the server 20. When there is a difference between the version on the terminal device 10 and the version on the server, the user can perform an update operation on the terminal device 10 to obtain the target map and target rendering file on the server.

[0051] In this embodiment, a target map and a target rendering file are pre-stored on the server. The target map is obtained by overlaying the initial model map with the initial ablation map according to a preset overlay algorithm; the target rendering file includes ablation trigger conditions and ablation parameters.

[0052] Step S302: updating the model map and the ablation map on the terminal device to the target map, and updating the rendering file on the terminal device to the target rendering file.

[0053] Optionally, when the terminal device 10 obtains the target map, the original model map and ablation map on the terminal device 10 are deleted and replaced with the target map to update the map.

[0054] Similarly, when the terminal device 10 obtains the target rendering file, the original rendering file on the terminal device 10 is deleted and replaced with the target rendering file to achieve the update of the rendering file.

[0055] Step S303: When the terminal device meets the ablation triggering condition in the target rendering file, the target map is rendered according to the ablation parameters in the target rendering file.

[0056] Optionally, the setting of the ablation trigger condition is not limited and can be selected according to actual needs. For example, continuing with the three-dimensional game as an example, the ablation trigger condition is set to the death of the BOSS in the game. When the BOSS in the game dies, it is considered that the terminal device 10 meets the ablation trigger condition in the target rendering file. At this time, the terminal device 10 renders the target map according to the ablation parameters in the target rendering file to achieve the ablation special effect after the death of the BOSS.

[0057] The texture rendering method provided by the embodiment of the present invention obtains the target texture and target rendering file on the server by responding to the user's operation on the terminal device, and then updates the model texture and ablation texture on the terminal device to the target texture, and updates the rendering file on the terminal device to the target rendering file. Then, when the terminal device meets the ablation trigger condition in the target rendering file, the target texture is rendered according to the ablation parameters in the target rendering file. Since the target texture required for rendering is obtained by covering the model texture with the ablation texture, after the terminal device updates the original model texture and ablation texture according to the target texture, it only needs to render the target texture, which reduces processing time. Moreover, when the terminal device meets the ablation trigger condition in the target rendering file, it only needs to render the target texture to achieve the ablation effect, which reduces resource consumption. Furthermore, the target texture is pre-stored on the server and is pre-made. After the user updates the terminal device, the target texture can be rendered. The processing time is not borne by the user, which improves the user experience.

[0058] In this embodiment, the target map is obtained by the following steps:

[0059] According to the solid model that requires ablation effects, an initial model map and an initial ablation map corresponding to the solid model are obtained, and according to a preset covering algorithm, the values ​​of different positions of the initial ablation map are covered with the values ​​of the A channel of the corresponding positions of the initial model map to obtain the target map.

[0060] Optionally, in the local production layer of the terminal device 10, a solid model requiring ablation effects is obtained, an initial model map is obtained from the solid model, and an initial ablation map corresponding to the solid model is obtained, wherein the production layer represents the local storage (Local Storage) on the terminal device 10. It should be noted that only the value of the A channel in the initial ablation map is adjustable; the initial model map has the values ​​of the four channels RGBA, but the value of the A channel in the initial model map is not adjustable. That is to say, when realizing the ablation effect of the map, it can be realized by adjusting the value of the A channel in the map. Therefore, the values ​​of different positions of the initial ablation map are overwritten with the value of the A channel of the corresponding same pixel position on the initial model map to obtain the target map.

[0061] Specifically, the covering algorithm can be expressed as follows:

[0062] (Model Map).A = (Ablation Map).A

[0063] In one example, a developer uses a terminal such as a personal computer (PC) to obtain a solid model that requires ablation effects in a local production layer, obtains an initial model map from the solid model, and obtains an initial ablation map corresponding to the solid model. According to the above-mentioned overlay algorithm, the values ​​of the A channel at the corresponding positions of the initial model map are overwritten with the values ​​of different positions of the initial ablation map to obtain a target map. The developer then uploads the target map to the server for storage through a terminal such as a PC.

[0064] In this embodiment, the target rendering file is obtained through the following steps:

[0065] Add ablation trigger conditions and ablation parameters to the initial rendering file to obtain the target rendering file.

[0066] Optionally, since the initial rendering file does not contain ablation trigger conditions and ablation parameters, in order to achieve rendering of the target map, it is necessary to add ablation trigger conditions and ablation parameters to the initial rendering file to obtain the target rendering file.

[0067] In one example, the developer obtains ablation trigger conditions and ablation parameters as needed, and uses a terminal such as a PC to add the ablation trigger conditions and ablation parameters to the initial rendering file in the local production layer to obtain the target rendering file. The developer then uploads the target rendering file to the server for storage through a terminal such as a PC.

[0068] In order to achieve the ablation effect by rendering the target map, the above step S303 includes:

[0069] When the terminal device meets the ablation trigger condition in the target rendering file, the ablation time, ablation coefficient and the value of the A channel of the target map in the target rendering file are multiplied to adjust the value of the A channel of the target map, thereby rendering the target map.

[0070] Optionally, the ablation parameters include ablation time and ablation coefficient. In this embodiment, the value of the A channel of the target map is adjusted, which can be expressed by the following formula:

[0071] Ablation time × ablation coefficient × the value of channel A of the target map

[0072] The ablation time represents the time when the target map starts to be rendered; the ablation coefficient represents the speed at which the target map is rendered; and the value of the A channel of the target map represents the position at which the target map starts to be rendered.

[0073] It should be noted that when the terminal device meets the ablation trigger conditions in the target rendering file, the ablation time is used to determine the time when the target map starts rendering, the ablation coefficient is used to determine the speed at which the target map is rendered, and the value of the A channel of the target map is used to determine the position at which the target map starts rendering. The value of the A channel of the target map is adjusted to render the target map, so that the target map gradually becomes transparent, thereby achieving the ablation effect.

[0074] In some scenarios, after the user performs an operation on the terminal device 10, there is a need to make the terminal device 10 set the value of the A channel of the target map accordingly. Based on this, please refer to Figure 4 , Figure 4 Another flowchart of a texture rendering method provided by an embodiment of the present invention. The method further includes:

[0075] Step S304: When the terminal device does not meet the ablation triggering condition, the value of the A channel of the target map is set to a preset value according to the target rendering file, so that the target map presents an opaque effect.

[0076] Optionally, continuing with the example of a three-dimensional game, in some embodiments, when a user uses the terminal device 10 to enter a virtual scene in the game, the terminal device 10 will begin rendering to present the characters, objects, etc. in the virtual scene to the user. In order to allow the user to clearly see the characters, objects, etc. in the virtual scene, the terminal device 10 needs to set the value of the A channel of the target map so that the target map presents an opaque effect. The preset value is not limited and can be set according to actual needs. It is understood that the value of the A channel can be set to a value between 0 and 1. For example, in this embodiment, in order to achieve a better opaque effect, the preset value can be set to 1.

[0077] In order to execute the corresponding steps in the above embodiments and various possible methods, a method for implementing a texture rendering device is given below. Figure 5 , Figure 5 This is a functional block diagram of a texture rendering device provided in an embodiment of the present invention. It should be noted that the basic principles and technical effects of the texture rendering device provided in this embodiment are the same as those in the aforementioned embodiments. For the sake of brevity, any details not mentioned in this embodiment are referred to the corresponding content in the aforementioned embodiments. The texture rendering device includes an acquisition module 401, an update module 402, and a rendering module 403.

[0078] Optionally, the above modules can be stored in the form of software or firmware. Figure 2 The memory shown in FIG. 1 or the operating system (OS) of the terminal device 10 may be fixed therein and may be Figure 2 Meanwhile, the data and program codes required to execute the above modules may be stored in the memory.

[0079] The acquisition module 401 is used to respond to the user's operation on the terminal device and acquire the target map and target rendering file on the server.

[0080] It can be understood that the acquisition module 401 can execute the above step S301.

[0081] The updating module 402 is configured to update the model map and the ablation map on the terminal device to the target map, and update the rendering file on the terminal device to the target rendering file.

[0082] It can be understood that the updating module 402 can execute the above step S302.

[0083] The rendering module 403 is configured to render the target map according to the ablation parameters in the target rendering file when the terminal device meets the ablation trigger condition in the target rendering file.

[0084] Optionally, the rendering module 403 is used to multiply the ablation time, ablation coefficient and the value of the A channel of the target map in the target rendering file to adjust the value of the A channel of the target map, thereby rendering the target map when the terminal device meets the ablation trigger condition in the target rendering file.

[0085] It can be understood that the rendering module 403 can execute the above step S303.

[0086] Optionally, the rendering module 403 is further configured to set the value of the A channel of the target map to a preset value according to the target rendering file when the terminal device does not meet the ablation trigger condition, so as to make the target map present an opaque effect.

[0087] It can be understood that the rendering module 403 can execute the above step S304.

[0088] In the texture rendering device provided by an embodiment of the present invention, the acquisition module obtains the target texture and target rendering file from the server in response to the user's operation on the terminal device. The update module then updates the model texture and ablation texture on the terminal device to the target texture, and updates the rendering file on the terminal device to the target rendering file. The rendering module then renders the target texture according to the ablation parameters in the target rendering file when the terminal device meets the ablation trigger condition in the target rendering file. Since the target texture required for rendering is obtained by overlaying the model texture with the ablation texture, after the terminal device updates the original model texture and ablation texture according to the target texture, it only needs to render the target texture, which reduces processing time. Moreover, when the terminal device meets the ablation trigger condition in the target rendering file, it only needs to render the target texture to achieve the ablation effect, which reduces resource consumption. Furthermore, the target texture is pre-stored on the server and is pre-made. After the user updates the terminal device, the target texture can be rendered, and the processing time is not borne by the user, thereby improving the user experience.
