Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a texture generation method, apparatus, and electronic device. Background Technology

[0002] In the generation of virtual scene assets, large areas such as ground or building walls require the use of many similar elements. Typically, a small texture is repeatedly applied across the XY plane of the UV mapping to create a larger target texture that fills the entire plane. However, because a small texture is repeatedly used, the resulting target texture often has poor visual quality, exhibiting noticeable seams and high repetition of feature elements within the small textures. Related techniques involve moving each small texture in image processing software to eliminate seams; however, this requires modifying the original small textures, making the process complex and tedious. Another approach is to randomly rotate and enlarge the small textures to address the high repetition of feature elements in the target texture. However, this method also creates seams between the rotated small textures and causes uneven brightness during UV overlay, resulting in a poor-quality final target texture. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a texture generation method, apparatus and electronic device to make the boundary blending between the first textures in the target texture more natural, while reducing the repetition of elements in the target texture, thereby improving the texture effect of the target texture.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Currently, in the generation of virtual scene assets, such as the production of large-scale CG scene assets, large areas of ground or building walls require the use of many similar elements, but there also need to be subtle differences between the elements, such as the grass and sand on the ground, and the brick texture on the building. In addition to generating effects using custom materials during the rendering process, most creators tend to use a single texture to repeat the object's UV space, that is, to repeat it multiple times on the XY plane control of the UV, thereby achieving the effect of using a small texture to cover the entire ground, thus obtaining a larger target texture.

[0026] However, the above method requires repeatedly using a small sticker for stitching, such as Figure 1 The texture generated by simply repeating and splicing small textures will inevitably have gaps in the visual effect, and there will also be a problem of excessive repetition of elements in the small textures. Therefore, it is necessary to adjust the degree of movement of the original small textures before repeating the UVs.

[0027] In related technologies, seams between small textures are manually eliminated by moving each texture in image processing software (such as Photoshop), for example, moving the texture in the middle of the X and Y axes, thus achieving a continuous four-dimensional pattern. However, this method requires modification of the original small textures, making the operation complex and tedious. Additionally, the problem of high repetition of feature elements in the target texture is usually solved by randomly rotating and enlarging the small textures. However, this method also results in seams between the rotated small textures, such as… Figure 2 As shown, the texture boundary processing is rather abrupt, and the UV overlay process produces local brightness inconsistencies, resulting in poor quality of the final generated target texture.

[0028] Based on this, embodiments of the present invention provide a texture generation method, apparatus, and electronic device, which can be applied to portable terminals, computers, and other electronic devices.

[0029] To facilitate understanding of this embodiment, a texture generation method disclosed in this invention will first be described in detail, such as... Figure 3 As shown, the method includes the following steps:

[0030] Step S302: Obtain the first texture, quantity parameters, and texture parameters;

[0031] The first texture mentioned above refers to the original texture used to generate the target texture. It includes feature elements that need to be repeatedly displayed. For example, if a large area of ​​building walls needs to be generated, the feature elements in the first texture typically include stones, soil, or brick walls. Similarly, if a large area of ​​grassland needs to be generated, the feature elements in the first texture typically include grass, gravel, and soil. Additionally, the first texture has a certain size and aspect ratio, such as a 1:1 ratio. The quantity parameters mentioned above are usually a single value, such as 100 or 120, and are usually preset by the operator. The texture parameters typically include multiple parameters, each representing a different meaning, such as size parameters (also called scaling parameters), rotation parameters, cropping parameters, resolution parameters, brightness parameters, etc.

[0032] In addition, the aforementioned first texture is mainly used to generate the target texture, the aforementioned quantity parameter is mainly used to generate the Vino map, indicating the number of polygons in the Vino map, and the aforementioned texture parameter is mainly used to process the first texture, but can also be used to process the target texture. In actual implementation, the above acquisition method is usually set by the staff in the graphical user interface displayed on the front end. After the staff completes the setting, the front end sends the first texture, quantity parameter, and texture parameter to the back end, thus obtaining the aforementioned first texture, quantity parameter, and texture parameter.

[0033] Step S304: Generate an initial Vinomap based on the quantity parameter; wherein the initial Vinomap consists of multiple sub-regions, and the number of sub-regions is related to the quantity parameter;

[0034] The aforementioned Vinograph can also be called a Voronoi diagram. The quantity parameter usually refers to the number of sub-regions in the Vinograph; for example, if the quantity parameter is 100, then the generated Vinograph will have 100 sub-regions. Furthermore, the aforementioned sub-regions usually refer to polygons, such as triangles, quadrilaterals, pentagons, hexagons, etc., and can also be called cells. Specifically, after obtaining the quantity parameter, a blank initial image of a specified size can be randomly generated. Multiple points are generated in this initial image, with the number of points being the same as the quantity parameter, and each point's position is unique. One possible implementation is to generate a Delaunay triangulation based on the generated points, determine the circumcenter of each triangle in the triangulation, and connect the circumcenters of adjacent triangles to obtain multiple polygons, each containing one previously generated point, thus obtaining the aforementioned initial Vinograph. Another possible implementation is to determine the intersection point of the perpendicular bisectors of adjacent lines, connect the adjacent intersection points to form multiple polygons, each containing one previously generated point, thus obtaining the aforementioned initial Vinograph.

[0035] like Figure 4 As shown, this includes multiple polygons, namely the aforementioned sub-regions, each distinguished by a different grayscale level. Each sub-region contains its center point, which is the point generated in the image above.

[0036] Step S306: Blur the edge regions of each sub-region in the initial Venn map to generate the target Venn map;

[0037] To eliminate gaps between the first textures filling each sub-region, the edge regions of each sub-region in the initial Vinomap can be blurred. Specifically, the blur value of the pixels at the boundary of each sub-region can be set to blur the boundary regions of each sub-region. The blur value indicates the degree of blurring in the image, such as... Figure 5 As shown, the boundaries of each sub-region are weakened, so that the boundary areas of each sub-region do not appear to have a sense of boundary visually.

[0038] Step S308: Scale and rotate the first texture based on the texture parameters, and fill the processed first texture into a sub-region of the target Vino map to generate the target texture.

[0039] To reduce the repetition of feature elements in the first texture image, the first texture image can be enlarged, reduced, and rotated using the obtained texture parameters. These texture parameters typically include the maximum enlargement parameter, the minimum reduction parameter, and the rotation angle range. For example, enlarging the first texture image by 10% yields one processed first texture image; reducing it by 10% yields another; rotating it clockwise by 20° yields one; and rotating it counterclockwise by 20° yields yet another. Alternatively, the first texture image can be enlarged first and then rotated to obtain a different processed first texture image. In this embodiment, scaling and rotating the first texture image based on the texture parameters results in multiple processed first texture images. Then, each processed first texture image is randomly filled into one of multiple sub-regions until each sub-region is completely filled with processed first texture images, thus obtaining the target texture image.

[0040] This invention provides a texture generation method, which involves obtaining a first texture, quantity parameters, and texture parameters; generating an initial Vinomap based on the quantity parameters; wherein the initial Vinomap consists of multiple sub-regions, the number of which is related to the quantity parameters; blurring the edges of each sub-region in the initial Vinomap to generate a target Vinomap; scaling and rotating the first texture based on the texture parameters, and filling the processed first texture into the sub-regions of the target Vinomap to generate the target texture. In this method, blurring the boundaries of each sub-region in the initial Vinomap and filling the rotated and scaled first texture into multiple sub-regions of the target Vinomap eliminates gaps at the boundaries of the first texture, making the boundary blending between the various first textures in the target texture more natural, while reducing the element repetition in the target texture, thereby improving the texture effect of the target texture.

[0041] The following describes the steps for blurring the edge regions of each sub-region in the initial Vinomap to generate the target Vinomap, along with one possible implementation:

[0042] For each sub-region in the initial Vinograph, starting from the target point of the sub-region and ending at the region boundary of the sub-region, different blur values ​​are sequentially set from the starting point to the ending point to generate the target Vinograph; wherein, the blur degree of the blur value set at the starting point of each sub-region in the target Vinograph is less than the blur degree of the blur value set at the ending point of the sub-region.

[0043] The target point mentioned above can be a point randomly generated in the initial image during the generation of the initial Vinomap. Specifically, for each sub-region in the initial Vinomap, a weight needs to be applied linearly to each boundary of the sub-region, using the target point of that sub-region as a reference. The applied weights increase sequentially, and each weight is multiplied by a specified blur value. Since the distance from the target point to each boundary is different, a boundary range with not entirely identical blur changes can be obtained; that is, the blur value of each boundary of the sub-region is different. The blur value is larger closer to the sub-region boundary and smaller closer to the target point. In other words, the boundary of each sub-region appears more blurred visually. Figure 5 As shown in the figure. In this method, by setting a large blur value for the boundary of each sub-region, the boundary regions between each sub-region in the target Vinograph are blurred, thus weakening the boundary gaps.

[0044] The above texture parameters include scaling and rotation parameters; the following describes step S308, which involves scaling and rotating the first texture based on the texture parameters, and then filling the processed first texture into a sub-region of the target Vino map to generate the target texture. One possible implementation is as follows:

[0045] (1) Based on the scaling and rotation parameters, the first texture is scaled and rotated to obtain multiple second textures;

[0046] Specifically, the first texture can be scaled, rotated, or both scaled and rotated. It should be noted that the scaling and rotation of the first texture are randomized, primarily based on scaling parameters. The scaling is performed within the range specified by the scaling parameters, and the rotation is performed within the range specified by the rotation parameters, thus resulting in multiple second textures.

[0047] The above scaling parameters include the scaling range of the first texture, and the above rotation parameters include the rotation range of the first texture. The following describes the steps of step (1) scaling and rotating the first texture according to the scaling parameters and rotation parameters to obtain multiple second textures. One possible implementation is to control the first texture to be randomly scaled within the scaling range and to control the first texture to be randomly rotated within the scaling range to obtain multiple second textures.

[0048] For example, the scaling range mentioned above could be 110%, indicating that the first texture can be magnified to a maximum of 110% and shrunk to a minimum of 90%. In other words, the first texture will randomly scale within a range of 90%-110%. The rotation range mentioned above could be ±18°, indicating that the first texture can be rotated a maximum of 18° clockwise and a maximum of 18° counterclockwise. This means the first texture will randomly rotate within a range of ±18°, resulting in multiple second textures. In this method, by using the scaling and rotation ranges to make the first texture randomly change within these ranges, multiple different second textures can be obtained, further reducing the repetition of feature elements in the first texture.

[0049] (2) Fill multiple sub-regions of the target Venn map with multiple second textures to obtain the initial texture;

[0050] Specifically, a target second texture is randomly selected from multiple second textures, and this target second texture is randomly filled into one of multiple sub-regions until each sub-region is filled, thus obtaining the initial texture.

[0051] (3) Based on the blur value of each pixel in the target Vino map, process the transparency value of the initial texture to obtain the target texture.

[0052] Since only the second texture is filled during the filling process, hard boundaries will be created between the sub-regions after the second texture is filled, resulting in noticeable seams. Therefore, based on the blurred values ​​obtained from the previous steps of blurring the boundaries of the sub-regions in the target Vino map, the transparency of the corresponding boundaries in the initial texture can be adjusted to weaken the visibility of the boundaries of each sub-region in the initial texture. For example, the transparency value of each pixel in the initial texture can be set to a specified value, and each specified value can be multiplied by the blurred value of the corresponding pixel in the target Vino map, thereby increasing the transparency of the boundary areas of each sub-region in the initial texture.

[0053] In the above method, the boundary blending effect in the initial texture is improved by using the Vino map fractal algorithm and the blur value of each pixel in the target Vino map, thus avoiding the excessive overlap error that occurs when using functions such as noise.

[0054] In step (3) above, the initial texture is processed based on the blur value of each pixel in the target Winnowing image to obtain the target texture. One possible implementation is to determine the blur value of each pixel in the target Winnowing image as the transparency value of the corresponding pixel in the initial texture to obtain the target texture.

[0055] In practice, the blur value can be directly obtained from the target Vinograph, and a blur mask can be generated based on the blur value, such as... Figure 7 As shown, the boundary regions of each sub-region are lighter in color, indicating a larger blur value in that region. The blur value of each pixel in the target Vino map is then used as the transparency value of the corresponding pixel's alpha channel in the initial texture. Figure 7 A lighter color at the boundary of each sub-region indicates greater transparency in that region. For example, ... Figure 6 The image shown is the first texture. The target texture obtained after the above steps is as follows: Figure 8 As shown, the feature elements include varying sizes and multiple mapping angles, and the various second maps achieve a seamless effect. This method uses the blurred range of the boundaries of sub-regions in the target Vinograph as transparency, eliminating hard boundaries caused by filling the second maps.

[0056] To further improve the texture effect of the target texture, the texture parameters also include resolution parameters. After scaling and rotating the first texture based on the texture parameters, and filling the processed first texture into multiple sub-regions in the target Vino map to generate the target texture, the method further includes: determining the resolution of the target texture to the target resolution corresponding to the resolution parameters.

[0057] The resolution parameters mentioned above are multiples of 1024. For example, if the obtained resolution parameter is 2048, then after generating the target texture, the resolution of the target texture will be updated to 2048 to increase or decrease the resolution of the target texture as needed. In this method, the resolution parameter can be set as needed to change the resolution of the target texture, thereby further improving the texture quality of the target texture.

[0058] In some existing technologies, the original textures need to be modified and processed using various image processing software, which is cumbersome, time-consuming, and labor-intensive. Therefore, in this embodiment, a graphical user interface (GUI) is provided through a terminal device. This GUI includes parameter setting controls; for example, such as... Figure 9 As shown, the bar controls to the right of Size, Rotation, Quantity, and Resolution are the parameter setting controls. The control for Size is used to set the scaling parameter, the control for Rotation is used to set the rotation parameter, the control for Quantity is used to set the quantity parameter, and the control for Resolution is used to set the resolution parameter.

[0059] It's also worth noting that the aforementioned terminal devices include both the UI front-end and the texture generation back-end. The front-end is written in TypeScript and Vue, compiled using the Electron framework, offering cross-platform advantages. The back-end algorithm is written in Python. Front-end UI settings and back-end algorithm-generated result previews are exchanged via RPC (Remote Procedure Call). The front-end Electron thread manages the UI process, RPC communication process, and back-end algorithm modules. The back-end algorithm modules are typically directly ported to various DCC (Digital Content Creation) software and engines. The use of TypeScript and Python, along with the Electron framework, allows for rapid development of software versions for different platforms. Furthermore, it can be easily integrated into most Python-supported content creation software.

[0060] In step S302 above, the step of obtaining the first texture, quantity parameters, and texture parameters can be implemented as follows: in response to the upload operation of the first texture, the first texture is obtained and displayed in the graphical user interface; in response to the parameter selection operation of the parameter setting control, the quantity parameters and texture parameters are obtained.

[0061] The above-mentioned response to the upload operation of the first image can be such that, in response to a trigger operation on the image upload control, the first image is uploaded to the terminal device and displayed. For example, as shown... Figure 9As shown, staff can click the "Upload Original Texture" control to display the textures currently stored on the device. Selecting the desired texture will upload the first texture to the terminal device, and it will also be displayed in the "Upload Original Texture" control. The UI process then sends the first texture to the backend algorithm process via an RPC client. Alternatively, staff can directly drag and drop the first texture into the "Upload Original Texture" area, which will then become the display area for the first texture.

[0062] Similarly, exemplified by, Figure 9 As shown, staff can slide the size control, rotation control, quantity control, and resolution control to select target parameters, such as... Figure 9 As shown, sliding the size control to 110% allows you to select a scaling parameter of 110%; sliding the rotation control to ±18° allows you to select a rotation parameter of ±18°; sliding the quantity control to 130 allows you to select a quantity parameter of 130; and sliding the resolution control to 4096 allows you to select a resolution parameter of 4096. Similarly, the texture parameters are sent to the backend algorithm process via the RPC client through the UI process.

[0063] Then, after receiving the texture parameters sent by the UI process via RPC communication, the process calls a pre-set algorithm module to generate the required target texture based on the first texture, quantity parameters, and texture parameters. In the above method, the parameter setting control allows users to directly enter the parameter adjustment stage after selecting the original texture, without needing to adjust the original texture itself. This makes the operation simple and convenient, further improving the efficiency of texture generation.

[0064] Furthermore, the aforementioned graphical user interface also includes a save control and a target texture preview area; for example, such as Figure 9 The "Save Settings" option shown corresponds to the save control mentioned above. Figure 9 The area indicated by ③ in the text corresponds to the target texture preview area mentioned above.

[0065] After scaling and rotating the first texture based on the texture parameters, and filling the processed first texture into a sub-region of the target Venn diagram to generate the target texture, the above method further includes: in response to a trigger operation on the save control, displaying a preview of the target texture in the target texture preview area; in response to a trigger operation on the preview, displaying the texture parameters and quantity parameters of the target texture on the parameter setting control.

[0066] In practice, after selecting all parameters, staff can click the save control to display the target texture in the target texture preview area and store it there. Clicking this area (i.e., clicking the displayed target texture) will show the corresponding quantity and texture parameters in the parameter setting controls. If the currently displayed target texture does not meet expectations, the quantity and texture parameters can be adjusted directly through the parameter setting controls, thereby adjusting the currently displayed target texture. This method allows users to click the save control after generating the target texture to display it in the graphical user interface. The preview window provides real-time confirmation of the final effect of the target texture, making it more convenient and faster.

[0067] The graphical user interface described above also includes output controls; for example, such as Figure 9 The "output" shown corresponds to the output control mentioned above. After scaling and rotating the first texture based on the texture parameters, and filling the processed first texture into a sub-region of the target Vinograph to generate the target texture, the method further includes: responding to a trigger operation on the output control and outputting the target texture to a specified storage space.

[0068] If staff observe the target texture displayed in the preview area and find that it meets expectations, they can click the output control to obtain the final result, that is, output the target texture to the specified storage space for later use.

[0069] Furthermore, the aforementioned graphical user interface includes a reset control; for example, such as Figure 9 The "Reset" option shown corresponds to the reset control mentioned above. The method also includes: responding to a trigger operation on the reset control and restoring the currently selected quantity and texture parameters to their initial values.

[0070] If the currently selected parameters do not meet expectations, or if you need to reset the currently selected parameters, you can directly click the reset control to restore the currently displayed parameters, such as 110%, ±18°, 130,4096, to 100%, 0°, 0,1024.

[0071] In the above method, the seamless texture front-end generation tool not only allows for convenient setting of the number of times the first texture is repeated through the editing interface, but also enables individual setting of the first texture's size and rotation randomness. Furthermore, it allows for easy previewing of the generation effects with different parameters, ultimately generating the desired seamless texture at the new resolution. Additionally, based on Voronoi fractals, a new algorithm is used to obtain irregular, uniformly blurred boundaries, significantly improving the gap effect between the boundaries of the first textures. This effectively eliminates gaps without altering the original textures. Simultaneously, the overall brightness of the seamless texture is maintained during the texture blending and stitching process, preventing inconsistent bright areas caused by overlap.

[0072] Corresponding to the above method embodiments, this invention provides a texture generation device, such as... Figure 10 As shown, the device includes:

[0073] Module 1001 is used to obtain the first texture, quantity parameters, and texture parameters;

[0076] The texture generation module 1004 is used to scale and rotate the first texture based on the texture parameters, and fill the processed first texture into a sub-region of the target Venn diagram to generate the target texture.

[0077] This invention provides a texture generation apparatus that acquires a first texture, quantity parameters, and texture parameters; generates an initial Vino map based on the quantity parameters; the initial Vino map consists of multiple sub-regions, the number of which is related to the quantity parameters; blurs the edges of each sub-region in the initial Vino map to generate a target Vino map; scales and rotates the first texture based on the texture parameters, and fills the processed first texture into the sub-regions of the target Vino map to generate the target texture.

[0078] Furthermore, the aforementioned target Vinio map generation module is also used to: for each sub-region in the initial Vinio map, starting from the center point of the sub-region and ending at the region boundary of the sub-region, sequentially set different fuzzy values ​​from the starting point to the ending point to generate the target Vinio map; wherein, the fuzziness of the fuzzy value set at the starting point of each sub-region in the target Vinio map is less than the fuzziness of the fuzzy value set at the ending point of the sub-region.

[0079] Furthermore, the above-mentioned texture parameters include scaling parameters and rotation parameters; the texture generation module is also used to: scale and rotate the first texture according to the scaling parameters and rotation parameters to obtain multiple second textures; fill multiple sub-regions in the target Vino map with the multiple second textures to obtain an initial texture; and process the transparency value of the initial texture based on the blur value of each pixel in the target Vino map to obtain the target texture.

[0080] Furthermore, the texture generation module is also used to: determine the blur value of each pixel in the target Vino map as the transparency value of the corresponding pixel in the initial texture map, thereby obtaining the target texture map.

[0081] Furthermore, the scaling parameters include the scaling range of the first texture; the rotation parameters include the rotation range of the first texture; the texture generation module is also used to: control the first texture to be randomly scaled within the scaling range, and control the first texture to be randomly rotated within the scaling range to obtain multiple second textures.

[0082] Furthermore, the above-mentioned texture parameters also include resolution parameters; the above-mentioned device also includes a resolution determination module: determining the resolution of the target texture as the target resolution corresponding to the resolution parameters.

[0083] Furthermore, a graphical user interface is provided through the terminal device, the graphical user interface including parameter setting controls; the above-mentioned acquisition module is also used to: in response to the upload operation of the first image, acquire the first image and display the first image in the graphical user interface; in response to the parameter selection operation of the parameter setting controls, acquire quantity parameters and image parameters.

[0093] The process involves obtaining a first texture, its quantity parameter, and texture parameters. Based on the quantity parameter, an initial Vinomap is generated, consisting of multiple sub-regions, the number of which is related to the quantity parameter. The edges of each sub-region in the initial Vinomap are blurred to generate a target Vinomap. The first texture is then scaled and rotated based on the texture parameters. This processed first texture is then used to fill the sub-regions in the target Vinomap, generating the target texture. This method blurs the boundaries of each sub-region in the initial Vinomap and fills the rotated and scaled first texture into multiple sub-regions of the target Vinomap, eliminating gaps in the first texture boundaries. This results in a more natural blending of the boundaries between different first textures in the target texture, while also reducing element redundancy in the target texture, thus improving the overall texture quality.

[0094] The steps described above for blurring the edge regions of each sub-region in the initial Vinograph to generate the target Vinograph include: for each sub-region in the initial Vinograph, starting from the center point of the sub-region and ending at its boundary, sequentially setting different blur values ​​from the starting point to the ending point to generate the target Vinograph; wherein the blur degree of the blur value set at the starting point of each sub-region in the target Vinograph is less than the blur degree of the blur value set at the ending point of the sub-region. In this method, by setting a larger blur value for the boundary of each sub-region, the boundary regions between each sub-region in the target Vinograph are blurred, weakening the boundary gaps.

[0095] The aforementioned texture parameters include scaling and rotation parameters. The steps of scaling and rotating the first texture based on these parameters, and then filling the processed first texture into a sub-region of the target Vino map to generate the target texture, include: scaling and rotating the first texture according to the scaling and rotation parameters to obtain multiple second textures; filling the multiple second textures into multiple sub-regions of the target Vino map to obtain an initial texture; and processing the transparency value of the initial texture based on the blur value of each pixel in the target Vino map to obtain the target texture. This method utilizes a Vino map fractal algorithm and the blur value of each pixel in the target Vino map to improve the boundary blending effect in the initial texture, avoiding the excessive overlap error that occurs when using functions such as noise.

[0096] The steps described above, which process the initial texture based on the blur value of each pixel in the target Vino map to obtain the target texture, include: determining the blur value of each pixel in the target Vino map as the transparency value of the corresponding pixel's alpha channel in the initial texture map, thus obtaining the target texture. In this method, the blur range of the boundary of the sub-region in the target Vino map is used as the transparency, eliminating hard boundaries caused by filling the second texture map.

[0097] The scaling parameters mentioned above include the scaling range of the first texture; the rotation parameters include the rotation range of the first texture; the steps of scaling and rotating the first texture according to the scaling and rotation parameters to obtain multiple second textures include: controlling the first texture to be randomly scaled within the scaling range, and controlling the first texture to be randomly rotated within the scaling range to obtain multiple second textures. In this method, by using the scaling and rotation ranges to make the first texture randomly change within that range, multiple different second textures can be obtained, further reducing the repetition of feature elements in the first texture.

[0098] The aforementioned texture parameters also include resolution parameters. After scaling and rotating the first texture based on these parameters, and filling multiple sub-regions in the target Vinograph with the processed first texture to generate the target texture, the method further includes: determining the resolution of the target texture to the target resolution corresponding to the resolution parameters. In this method, the resolution parameters can be set as needed, thereby changing the resolution of the target texture and further improving the texture quality.

[0099] The aforementioned method provides a graphical user interface (GUI) via a terminal device, which includes parameter setting controls. The steps for obtaining the first texture, quantity parameters, and texture parameters include: in response to an upload operation of the first texture, obtaining the first texture and displaying it in the GUI; and in response to a parameter selection operation on the parameter setting controls, obtaining the quantity parameters and texture parameters. In this method, after selecting the original texture using the parameter setting controls, the user can directly enter the parameter adjustment stage without needing to adjust the original texture. This simplifies the operation and further improves texture generation efficiency.

[0100] The method described above provides a graphical user interface (GUI) via a terminal device. The GUI includes a save control and a target texture preview area. Following the steps of scaling and rotating the first texture based on texture parameters, and filling the processed first texture into a sub-region of the target Vinograph to generate the target texture, the method further includes: responding to a trigger operation on the save control by displaying a preview of the target texture in the target texture preview area; and responding to a trigger operation on the preview image by displaying the texture parameters and quantity parameters of the target texture on the parameter setting control. In this method, after generating the target texture, clicking the save control displays the target texture in the GUI, and the preview window allows for real-time confirmation of the final effect of the target texture, making it more convenient and faster.

[0101] The above-mentioned method provides a graphical user interface through a terminal device, the graphical user interface including an output control; after scaling and rotating the first texture based on texture parameters, filling the processed first texture into a sub-region of the target Venn diagram to generate a target texture, the above-mentioned method further includes: responding to a trigger operation on the output control and outputting the target texture to a specified storage space.

[0102] The above provides a graphical user interface via a terminal device, the graphical user interface including a reset control; the above method further includes: in response to a trigger operation on the reset control, restoring the currently selected quantity parameter and texture parameter to their initial parameters.
