[0021] In order to enable those skilled in the art to better understand the scheme of the present disclosure, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present disclosure.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0023] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following explanations:

[0024] Normal: is a vector that describes the direction of a surface at a specific location. In 3D rendering, normal information is very important because they determine how a surface reflects light.

[0025] Normal information: Usually used to render surface details, such as textures, bump maps, roughness, and metalness. This information can be achieved through normal maps, which are a special type of texture used to simulate geometric details of surfaces in 3D rendering.

[0026] Normal map: contains a set of normal vectors that describe the direction of the surface at each point on the surface. By using normal maps, you can simulate the geometric details of the surface without increasing the geometric complexity, thereby obtaining a more realistic rendering effect. In 3D modeling software, you can achieve high-quality rendering effects by storing the normal information of a high-resolution model in a normal map and then applying the normal map to a low-resolution model.

[0027] Texture Resolution: refers to the size of the unit area occupied by each pixel in the texture map. It is usually expressed in the form of pixels per unit or pixels per inch to measure the clarity and detail of the texture. In games, texture maps play a very important role. They can make the game scenes more realistic and vivid. However, the accuracy of texture maps has a great impact on game performance and the quality of game scenes. Generally, the higher the accuracy of texture maps, the more memory they occupy, and the greater impact on game performance. Therefore, in the process of game production, it is necessary to reasonably select the accuracy of texture maps according to the needs of the game and the performance of the device. Generally speaking, on lower-end devices, lower texture map accuracy should be selected to improve game performance. On higher-end devices, higher texture map accuracy can be selected to obtain higher image quality and finer details.

[0028] RGB channels: refers to the three color channels in the color model, namely red (R: Red), green (G: Green) and blue (B: Blue). In computer graphics and digital image processing, RGB channels are one of the basic ways to represent colors. The way RGB channels represent colors is to decompose colors into three different color channels, each of which contains a color component, namely red, green and blue components. By adjusting the brightness and saturation of the color components in each channel, a variety of different colors can be created. In image processing, RGB channels can be used to adjust the color, contrast, brightness, etc. of an image. For example, the overall hue of an image can be warmed by increasing the brightness in the red channel, or the image can be made cooler by reducing the brightness in the blue channel.

[0029] In a possible implementation, in view of the fact that texture mapping in the field of asset production is usually carried out by relying on art designers to use texture drawing software to draw various types of textures, the inventors, after practice and careful research, still found that there is a technical problem of low texture mapping drawing efficiency. Based on this, a method for processing texture mapping is proposed, and the technical concept adopted is to obtain multiple texture maps; generate at least one first preset map corresponding to the multiple texture maps, wherein the pixel values ​​of at least one channel in the first preset map are used to mix the multiple texture maps; based on the pixel values ​​of at least one channel in the first preset map, the multiple texture maps are mixed to obtain a mixed texture map, so that art designers can mix multiple texture maps by the pixel values ​​of the channels when drawing a small number of texture maps, and expand and generate more mixed texture maps, thereby solving the technical problem of low texture mapping drawing efficiency in the process of game asset production, and further achieving the technical effect of improving the efficiency of game asset production.

[0030] The texture map processing method in one embodiment of the present disclosure can be run on a local terminal device or a server. When the texture map processing method is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0031] In an optional implementation, various cloud applications can be run under the cloud interaction system, such as cloud games. Taking cloud games as an example, cloud games refer to a game mode based on cloud computing. In the operation mode of cloud games, the running body of the game program and the main body of the game screen presentation are separated. The storage and operation of the texture map processing method are completed on the cloud game server. The role of the client device is used for data reception, transmission and presentation of the game screen. For example, the client device can be a display device with data transmission function close to the user side, such as a mobile terminal, a TV, a computer, a handheld computer, etc.; but the cloud game server in the cloud is used for information processing. When playing the game, the player operates the client device to send an operation instruction to the cloud game server. The cloud game server runs the game according to the operation instruction, encodes and compresses the game screen and other data, and returns it to the client device through the network. Finally, the client device decodes and outputs the game screen.

[0032] In an optional implementation, taking a game as an example, the local terminal device stores the game program and is used to present the game screen. The local terminal device is used to interact with the player through a graphical user interface, that is, the game program is downloaded and installed and run by the conventional electronic device. The local terminal device can provide the graphical user interface to the player in a variety of ways, for example, it can be rendered and displayed on the display screen of the terminal, or provided to the player through holographic projection.

[0033] For example, the local terminal device can be a mobile terminal, a computer terminal or a similar computing device, which may include a display screen and a processor, wherein the display screen is used to present a graphical user interface, the graphical user interface includes a game screen, and the processor is used to run the game, generate the graphical user interface and control the display of the graphical user interface on the display screen.

[0034] Taking running on a mobile terminal as an example, the mobile terminal may be a smart phone, a tablet computer, a PDA, a mobile Internet device, a PAD (Portable Android Device), a game console, or other terminal devices. Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a texture mapping processing method according to an embodiment of the present disclosure. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 and a memory 104 for storing data. Optionally, the mobile terminal may further include a transmission device 106, an input and output device 108 and a display device 110.

[0035] Those skilled in the art will understand that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0036] According to one embodiment of the present disclosure, an embodiment of a method for processing a texture map is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] In a possible implementation, the embodiment of the present disclosure provides a method for processing texture mapping. Figure 2 is a flowchart of a method for processing a texture map according to one embodiment of the present disclosure, such as Figure 2 As shown, the method comprises the following steps:

[0038] S202, obtaining multiple texture maps.

[0039] Specifically, the above-mentioned texture map can be used to represent a map pre-drawn by an artist to simulate the details and materials of the model surface.

[0040] Generally, the above-mentioned texture maps are determined based on the model to be rendered. For example, when the model to be rendered is a wall, the multiple texture maps may include multiple layers of stacked bricks representing the base image, and cement representing the surface of the bricks.

[0041] S204, generating at least one first preset map corresponding to the multiple texture maps, wherein the pixel value of at least one channel in the first preset map is used to mix the multiple texture maps.

[0042] Specifically, the above-mentioned first preset map can be used to represent an image composed of black and white information. An image usually contains four channels, namely R (red) channel, G (green) channel, B (blue) channel and A (transparency channel). Therefore, the pixel value of each channel in the first preset map can range from 0 to 1.

[0043] Generally, the grayscale value interval can be expressed as [0, 255]. In the present application, the interval value of [0, 255] can be converted to [0, 1], that is, the pixel value is expressed by [0, 1].

[0044] In an optional embodiment, the number of first preset maps can be determined based on multiple texture maps. When there are two texture maps, the number of corresponding first preset maps is one, and the two texture maps correspond to any one channel in the first preset map; when there are three texture maps, the number of corresponding first preset maps is one, and the three texture maps correspond to any three channels in the first preset map; when there are four texture maps and the first preset map contains four channels, the number of corresponding first preset maps can be one, and the four texture maps correspond to the four channels in the first preset map one-to-one; when there are four texture maps and the first preset map contains three channels, the number of corresponding first preset maps can also be two, that is, two of the four texture maps correspond to any two channels in the first preset map one-to-one, and the other two texture maps of the four texture maps correspond to any two channels in the second preset map one-to-one. In addition, when the plurality of texture maps includes at least five texture maps, the at least five texture maps need to be grouped, and the texture maps need to be mixed respectively for the grouped texture maps.

[0045] S206: Based on the pixel value of at least one channel in the first preset map, multiple texture maps are mixed to obtain a mixed texture map.

[0046] Specifically, the above-mentioned mixed texture map can be used to represent a map obtained by mixing multiple texture maps at a mixing ratio determined based on pixel values.

[0047] In an optional embodiment, in the process of mixing multiple texture maps, it is necessary to predetermine the pixel value of at least one channel in a first preset map. By proportionally converting the pixel value, the mixing ratio of each texture map can be determined, and then the multiple texture maps are mixed according to the mixing ratio to obtain a mixed texture map.

[0048] Exemplarily, taking two texture maps as an example, if the pixel value of a channel in the first preset map is predetermined to be 0.7, the mixing ratio is determined to be 70%:30%, and then based on the mixing ratio of 70%:30%, multiple texture maps are mixed to obtain a mixed texture map.

[0049] In another optional embodiment, in order to avoid errors in mixed texture maps caused by determining the mixing ratio directly based on the pixel values ​​of at least one channel, multiple texture maps can be divided into base maps and non-base maps, wherein the base map can be a pre-set texture map. In the process of determining the mixing ratio of each texture map, it is necessary to determine the mixing ratio of the non-base map based on the pixel value, further determine the mixing ratio of the base map, and mix the non-base map and the base map in the multiple texture maps according to the mixing ratio of the non-base map and the mixing ratio of the base map to obtain a mixed texture map.

[0050] In summary, by acquiring multiple texture maps; generating at least one first preset map corresponding to the multiple texture maps, wherein the pixel values ​​of at least one channel in the first preset map are used to mix the multiple texture maps; based on the pixel values ​​of at least one channel in the first preset map, the multiple texture maps are mixed to obtain a mixed texture map. It is easy to notice that by generating at least one first preset map corresponding to the multiple texture maps, and mixing the multiple texture maps based on the pixel values ​​of at least one channel in the first preset map, a mixed texture map can be obtained, which enables art designers to mix multiple texture maps by the pixel values ​​of the channel when drawing a small number of texture maps, and expand and generate more mixed texture maps, thereby achieving the technical effect of reducing the difficulty of drawing texture maps, shortening the drawing cycle of texture maps, and thereby improving the efficiency of game asset production, thereby solving the technical problem of low texture map drawing efficiency in the process of game asset production.

[0051] Optionally, in the case where the multiple texture maps include two texture maps, the multiple texture maps are mixed based on the pixel values ​​of at least one channel in the first preset map to obtain a mixed texture map, including: obtaining the pixel value of a preset channel in the first preset map; determining a first mixing ratio of the two texture maps based on the pixel value of the preset channel; and mixing the two texture maps based on the first mixing ratio to obtain a mixed texture map.

[0052] Specifically, the above-mentioned preset channel can be used to represent any one of the four channels in the first preset map, or a channel pre-specified by an artist.

[0053] In an optional embodiment, when multiple texture maps include two texture maps, a first preset map corresponding to the two texture maps can be generated, and then based on the pixel value of a preset channel in the first preset map, a first mixing ratio of the two texture maps is determined, and the two texture maps are mixed based on the first mixing ratio to obtain a mixed texture map. Exemplarily, when the pixel value of the preset channel is 0.8, by proportionally converting 0.8, it can be obtained that the mixing ratio of one of the two texture maps is 80%, and the mixing ratio of the other texture map is 20%. Therefore, the above-mentioned first mixing ratio is 80%:20%.

[0054] In another optional embodiment, in the process of determining the first mixing ratio of the two texture maps based on the pixel value of the preset channel, it is necessary to perform a proportional conversion on the pixel value to obtain the converted first mixing ratio. Exemplarily, when the pixel value of the preset channel is 0.8, by performing a proportional conversion on 0.8, the mixing ratio of the non-base map in the first preset map can be obtained to be 85%, and the mixing ratio of the base map in the remaining first preset map is 15%, and the above-mentioned first mixing ratio can be obtained to be 85%:15%, and then the two texture maps are mixed based on the first mixing ratio to obtain a mixed texture map.

[0055] In summary, by determining a first mixing ratio based on the pixel values ​​of a preset channel in a first preset map and mixing the two texture maps when multiple texture maps include two texture maps, the purpose of mixing the two texture maps based on the first mixing ratio is achieved.

[0056] Optionally, based on the pixel values ​​of a preset channel, a first mixing ratio of the two texture maps is determined, including: based on the pixel values ​​of the preset channel, determining the mixing ratio of the first texture map among the two texture maps; in response to the mixing ratio of the first texture map being less than a first preset ratio, obtaining the difference between the first preset ratio and the mixing ratio of the first texture map, and obtaining the mixing ratio of the second texture map among the two texture maps; or in response to the mixing ratio of the first texture map being greater than or equal to the first preset ratio, determining the mixing ratio of the second texture map to be the second preset ratio; and obtaining the first mixing ratio based on the mixing ratio of the first texture map and the mixing ratio of the second texture map.

[0057] Specifically, the first texture map mentioned above can be used to represent a texture map representing a non-base image.

[0058] The second texture map mentioned above can be used to represent the texture map representing the base image.

[0059] The first preset ratio mentioned above can be used to represent a preset ratio for judging the mixing ratio. Generally, the first preset ratio is represented as 100%.

[0060] The second preset ratio mentioned above can be used to represent the mixing ratio of the second texture map that is preset when the mixing ratio of the first texture map is greater than or equal to the first preset ratio. Generally, the second preset ratio is represented as 0.

[0061] In an optional embodiment, in the process of determining the first mixing ratio of two texture maps based on the pixel values ​​of a preset channel, it is necessary to determine the mixing ratio of the first texture map through the pre-set pixel values ​​in the preset channel, and at the same time judge whether the mixing ratio of the first texture map is less than the first preset ratio of 100%. When the mixing ratio of the first texture map is less than the first preset ratio of 100%, it means that there is still a mixing ratio of the second texture map. The mixing ratio of the second texture map is obtained by obtaining the difference between the first preset ratio of 100% and the mixing ratio of the first texture map, and the above-mentioned first mixing ratio is obtained based on the mixing ratio of the first texture map and the mixing ratio of the second texture map. The first mixing ratio in this case is determined as the mixing ratio of the first texture map: the mixing ratio of the second texture map.

[0062] In another optional embodiment, when the mixing ratio of the first texture map is not less than the first preset ratio of 100%, it means that there is no mixing ratio of the second texture map, that is, there is no need to mix the second texture map. Therefore, the mixing ratio of the second texture map can be determined to be the second preset ratio of 0, and then based on the mixing ratio of the first texture map and the mixing ratio of the second texture map, the above-mentioned first mixing ratio is obtained. The first mixing ratio in this case is determined to be the mixing ratio of the first texture map, that is, the final mixed texture map is the first texture map.

[0063] Figure 3 is a schematic diagram of mixing two texture maps according to one embodiment of the present disclosure, such as Figure 3 As shown, the upper layer is a multi-layer stacked brick, corresponding to the second texture map, that is, the base map, and the lower layer is the cement covering the surface of the bricks, corresponding to the first texture map, that is, the non-base map. The corresponding first preset map is generated by the first texture map and the second texture map, and the pixel value of the preset channel in the first preset map is used to determine whether the base map is displayed in black (that is, the pixel value is 0) and the non-base map is displayed in white (that is, the pixel value is 1), and then the two texture maps are mixed based on the first mixing ratio to obtain a mixed texture map.

[0064] Optionally, when the plurality of texture maps include three texture maps or four texture maps, the plurality of texture maps are mixed based on the pixel values ​​of at least one channel in the first preset map to obtain the mixed texture map, including: obtaining the pixel values ​​of the plurality of channels in the first preset map, wherein the plurality of channels are mixed with the plurality of texture maps; Figure 1 One-to-one correspondence; based on the pixel values ​​of the multiple channels, determining a second mixing ratio of the multiple texture maps; based on the second mixing ratio, mixing the multiple texture maps to obtain a mixed texture map.

[0065] Specifically, the number of the above-mentioned multiple channels is consistent with the number of multiple texture maps, that is, when the multiple texture maps include three texture maps, the corresponding first preset map includes three channels; when the multiple texture maps include four texture maps, the corresponding first preset map includes four channels, and so on.

[0066] In an optional embodiment, when the multiple texture maps include three texture maps or four texture maps, a corresponding first preset map is generated using the three texture maps or the four texture maps, and pixel values ​​of multiple channels in the first preset map can be obtained at the same time, and then a second mixing ratio of the multiple texture maps is determined based on the pixel values ​​of the multiple channels, and the above-mentioned mixed texture map can be obtained by mixing the multiple texture maps.

[0067] In another optional embodiment, in the process of obtaining the pixel values ​​of multiple channels in the first preset map, the corresponding channel pixel values ​​can be determined based on the number of multiple texture maps. Specifically, in the case where the multiple texture maps include three texture maps, the three texture maps correspond to three channels, and the pixel values ​​belonging to the non-base map channels in the three channels can be determined, and the second mixing ratio of the three texture maps can be determined based on the pixel values; in the case where the multiple texture maps include four texture maps, the four texture maps correspond to four channels. Similarly, the pixel values ​​belonging to the non-base map channels in the four channels can be determined, and the second mixing ratio of the four texture maps can be determined based on the pixel values. After determining the second mixing ratio corresponding to different numbers of texture maps, it is necessary to mix the three texture maps or the four texture maps based on the second mixing ratio to obtain a mixed texture map. Among them, in the process of mixing multiple texture maps based on the second mixing ratio, the multiple texture maps can be mixed by the non-base map mixing ratio and the base map mixing ratio in the second mixing ratio, that is, the corresponding non-base map in the multiple texture maps is adjusted by the non-base map mixing ratio, and the corresponding base map in the multiple texture maps is adjusted by the base map mixing ratio, and then the adjusted texture maps are superimposed to obtain the above-mentioned mixed texture map.

[0068] Optionally, based on the pixel values ​​of multiple channels, a second mixing ratio of multiple texture maps is determined, including: based on the pixel value of a first channel among the multiple channels, determining the mixing ratio of the texture map corresponding to the first channel, wherein the first channel satisfies a preset condition; obtaining the sum of the mixing ratios of the texture maps corresponding to the first channel to obtain a total mixing ratio; in response to the total mixing ratio being less than a first preset ratio, obtaining the difference between the first preset ratio and the total mixing ratio to obtain the mixing ratio of the texture map corresponding to the second channel, wherein the second channel is a channel among the multiple channels other than the first channel; or in response to the total mixing ratio being greater than or equal to the first preset ratio, determining the mixing ratio of the texture map corresponding to the second channel to be a second preset ratio; obtaining a second mixing ratio based on the mixing ratio of the texture map corresponding to the first channel and the mixing ratio of the texture map corresponding to the second channel.

[0069] Specifically, the above-mentioned preset conditions can be used to represent the pre-set conditions that satisfy the non-base map channel.

[0070] The above-mentioned mixing ratio can be used to represent the mixing ratio of the corresponding texture map when the first channel is a non-base map channel, wherein the above-mentioned first channel includes at least one channel.

[0071] The above-mentioned total mixing ratio can be used to represent the sum of the mixing ratios of the texture maps corresponding to the multiple first channels that satisfy the non-base map channel.

[0072] The second channel mentioned above can be used to represent the channels among the multiple channels that satisfy the base map channel, that is, the channels among the multiple channels except the first channel.

[0073] In an optional embodiment, in the process of determining the second mixing ratio of multiple texture maps based on pixel values ​​of multiple channels, it is necessary to obtain the pixel value of a first channel among the multiple channels, wherein the first channel satisfies the non-base map channel, and then based on the pixel value of the first channel, determine the mixing ratio of the texture map corresponding to the first channel, and then obtain the sum of the mixing ratios of the texture maps corresponding to the first channel to obtain a total mixing ratio, wherein the total mixing ratio is characterized as the sum of the mixing ratios of the texture maps corresponding to the non-base map channels in the multiple channels, and then determine whether the total mixing ratio is less than the first preset ratio of 100%, and determine the mixing ratio of the texture map corresponding to the second channel through different judgment results.

[0074] When the total mixing ratio is less than the first preset ratio of 100%, it means that there is still a mixing ratio of the texture map that satisfies the base map channel. Therefore, the difference between the first preset ratio of 100% and the total mixing ratio can be obtained to obtain the mixing ratio of the texture map corresponding to the second channel, that is, the mixing ratio of the texture map that satisfies the base map channel; when the total mixing ratio is greater than or equal to the first preset ratio of 100%, it means that there is no mixing ratio of the texture map that satisfies the base map channel, that is, there is no need to mix the texture map corresponding to the second channel. Therefore, the mixing ratio of the texture map corresponding to the second channel is determined to be the second preset ratio of 0, and then after determining the mixing ratio of the texture map corresponding to the second channel under different judgment results, the second mixing ratio is obtained based on the mixing ratio of the texture map corresponding to the first channel and the mixing ratio of the texture map corresponding to the second channel.

[0075] Optionally, the method includes: obtaining priorities of multiple channels; determining a first channel and a second channel based on the priorities of the multiple channels, wherein the priority of the first channel is higher than the priority of the second channel, and the priority of the second channel is the minimum priority among the priorities of the multiple channels.

[0076] Specifically, the above priorities can be used to indicate the priorities of a plurality of preset channels.

[0077] Exemplarily, in the case where the multiple channels are three channels, the above priorities may be R>G>B, that is, the priority of the R channel is greater than the priority of the G channel which is greater than the priority of the B channel. It should be noted that the above is only an exemplary description and the priority is not specifically limited here.

[0078] In an optional embodiment, in the process of determining the first channel and the second channel among the multiple channels, the first channel and the second channel may be determined according to the preset priorities of the multiple channels. Specifically, when the multiple channels are the R channel, the G channel, and the B channel, the R channel and the G channel may be determined as the first channel and the B channel may be determined as the second channel according to the above priorities.

[0079] It should be noted that, when the pixel values ​​of the R channel, G channel and B channel all show white (that is, the pixel value is 1), the texture of the R channel can be displayed preferentially through the above-mentioned priority, that is, the mixing ratio of the texture map corresponding to the R channel is 100%, and the mixing ratio of the texture maps corresponding to other channels is 0; when the pixel values ​​of the R channel, G channel and B channel all show black (that is, the pixel value is 0), the above-mentioned priority can be used to determine that the mixing ratio of the texture maps corresponding to the R channel and G channel is 0, and the mixing ratio of the texture map corresponding to the B channel is 100%, that is, the texture of the B channel is displayed preferentially.
