Description

Background Art

[0002] In large-scale games, there are usually many large-scale game scenes. When making large-scale game scenes, in order to ensure that the screen ratio is not deformed, four-square continuous mapping (TillingMap) is usually used to make texture details and then generate large-area random texture maps. However, the texture map generated by the above method has a high degree of texture repetition, which makes the game screen easy to be exposed and lose authenticity.

[0003] In order to reduce the texture repetition of the above texture maps, the existing technical solutions usually use a rectangular mask to perform blending and connection processing on the seams of the texture maps. However, in the above technical solutions, due to the limitation of the rectangular shape of the blending mask, the high repetition of the texture maps cannot be effectively removed, and the processed texture is less rich, which in turn affects the artistic effect of the game scene production. Summary of the invention

This method uses a target mask map with richer polygonal shapes to realize the rotation of the texture map to be processed in the target direction, and then distorts and divides the seamless map so that it does not contain repeated textures, thereby solving the technical problem of high texture repetition in the prior art and greatly improving the effect quality of the art scene.

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, exemplary embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the exemplary embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0035] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0036] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the steps. For example, some steps may be decomposed, while some steps may be combined or partially combined, so the actual execution order may change according to the actual situation.

[0037] In large-scale games, there are usually many large-scale game scene images, such as grass textures and sand textures on large-area virtual surfaces. When making large-area game scenes, in order to ensure that the screen ratio is normal and not deformed, four-square continuous mapping (Tilling Map, also known as seamless mapping) is usually used to create texture details and then generate random texture maps in a large area.

[0038] It should be explained that four-dimensional continuous mapping is a method of evenly placing one or more main textures in a unit space, and repeatedly arranging at least one main texture to cover the entire scene screen to ensure seamless splicing, thereby showing the overall effect of the game scene screen. Figure 1A , Figure 1B An exemplary description is given.

[0039] Figure 1A A schematic diagram of a four-sided continuous mapping in this exemplary embodiment is shown, Figure 1A As shown, the four-way continuous mapping can ensure the connection of the texture in the up and down directions and the left and right directions, but it cannot achieve the texture connection in directions such as the left and top, the right and bottom.

[0040] Figure 1B A schematic diagram of a scene in which a random texture map in a large area is generated based on a four-square continuous map in this exemplary embodiment is schematically shown, referring to Figure 1B As shown, it is for Figure 1A The random texture map is obtained by repeatedly arranging the four continuous maps shown in the figure. Figure 1B From the random texture map shown, it can be seen that in a larger area, especially when the viewing angle (such as the virtual observation camera) is far away from the virtual model, there will be a problem of high repetition of texture details in some areas, which can easily lead to the picture being blemish-free and losing authenticity, making it difficult to meet the artistic requirements in the application scenario.

[0041] In the related technical solutions, a rectangular mask is usually used to perform blending and connection processing on the texture edge (i.e. the joint of four continuous textures). Figure 2A , Figure 2B As shown, Figure 2A A schematic diagram showing a texture map to be processed in a related art in this exemplary embodiment; Figure 2B A schematic diagram of a rectangular mask used in a related technology in this exemplary embodiment is shown schematically. Figure 2A A random texture map is obtained by copying and arranging a four-square continuous map based on a grid multiple times. Figure 2A The random texture map formed by mixing and connecting the joints of multiple square continuous maps can be used Figure 2B The white portion of the mask shown is Figure 2A The texture edge is rotated in the Z-axis direction to reduce the repetitiveness by tilting the texture on the Z-axis.

[0042] However, in the above technical solution, since the shape of the hybrid mask is relatively rigid and only exists in a rectangular shape, the texture repetition is still high even if the texture edge is rotated on the Z axis, especially when the virtual camera is far away from the virtual model in the game scene, the texture repetition cannot be effectively removed. In addition, since the mask shape used is the same, the processed texture map is less rich, which affects the artistic effect of the game scene production, and thus it is difficult to meet the actual needs of large-area scene production.

[0043] In view of the above problems, the exemplary embodiment of the present disclosure proposes a method for processing texture maps, which adopts the method of obtaining a target mask map, which is composed of multiple continuous polygons; mapping the target mask map to the texture map to be processed, so as to rotate each texture in the texture map to be processed in the target direction based on the target mask map, and obtain a processed first target texture map; wherein the texture map to be processed is formed by multiple splicing of at least one basic texture map. The method uses a target mask map with richer polygonal shapes to realize the rotation of the texture map to be processed in the target direction, and then distorts and divides the seamless map so that it does not contain repeated textures, thereby solving the technical problem of high texture repetition in the prior art and greatly improving the effect quality of the art scene. In addition, the method uses a target mask map with richer shapes, so that different texture effects can be achieved by using rich polygons, thereby improving the richness and randomness of the texture map, avoiding the technical problem of poor authenticity caused by the scene screen being exposed, and thus improving the user experience.

[0044] The following will be combined Figure 3 The texture mapping processing method and device proposed in the present disclosure are applied to Figure 3 The embodiments are described in the system architecture of the exemplary application environment shown.

[0045] Figure 3 A schematic diagram of an application scenario provided for an embodiment of the present application, in which a terminal device 301 and a server 302 may be included.

[0046] The terminal device 301 can be, for example, a mobile phone, a tablet computer (PAD), a laptop computer, a desktop computer, or any other device involved in making texture maps. The terminal device 301 can be installed with a target application, and the target application can have functions such as texture map display. The application involved in the embodiment of the present application can be a software client, or a client such as a web page or a small program. The server 302 is a server corresponding to the software or a web page, a small program, etc., and does not limit the specific type of the client.

[0047] The server 302 may be a background server of the target application, used to provide corresponding background services for it, such as texture mapping processing services, etc. It may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, i.e., content delivery networks (CDNs), and big data and artificial intelligence platforms, but is not limited thereto.

[0048] It should be noted that the processing method of the texture map in the embodiment of the present application can be executed separately by the terminal device 301 or the server 302, or it can be executed jointly by the server 302 and the terminal device 301. In actual application, specific configuration can be performed according to the situation, and the present application does not make specific limitations here. The server 302 and the terminal device 301 can both include one or more processors, memories, and interactive I / O interfaces, etc. In addition, the server 302 can also be configured with a database, which can be used to store data and configuration files in the processing process of the texture map. Among them, the memory of the server 302 and the terminal device 301 can also store the program instructions required to be executed in the processing method of the texture map provided in the embodiment of the present application, and these program instructions can be used to implement the processing process of the texture map provided in the embodiment of the present application when executed by the processor.

[0049] It should be noted that when the texture map processing method provided in the embodiment of the present application is executed by the server 302 or the terminal device 301 alone, the above-mentioned application scenario may also only include a single device of the server 302 or the terminal device 301, or the server 302 and the terminal device 301 may be considered to be the same device. Of course, in actual application, when the recommendation reason generation method provided in the embodiment of the present application is jointly executed by the server 302 and the terminal device 301, the server 302 and the terminal device 301 may also be the same device, that is, the server 302 and the terminal device 301 may be different functional modules of the same device, or virtual devices virtualized from the same physical device.

[0050] In the embodiment of the present application, the terminal device 301 and the server 302 can be directly or indirectly connected to each other through one or more networks 303. The network 103 can be a wired network or a wireless network. For example, the wireless network can be a mobile cellular network or a wireless fidelity (Wireless-Fidelity, WIFI) network. Of course, it can also be other possible networks, which are not limited in the embodiment of the present application. It should be noted that Figure 3 The figure is only an example. In fact, the number of terminal devices and servers is not limited and is not specifically limited in the embodiments of the present application.

[0051] For example, in an exemplary embodiment, a terminal device obtains a target mask map, which is composed of multiple continuous polygons; the target mask map is mapped to a texture map to be processed, so as to rotate each texture in the texture map to be processed in a target direction based on the target mask map, so as to obtain a processed first target texture map; wherein the texture map to be processed is formed by multiple splicing of at least one basic texture map.

[0052] Below, in combination with the application scenarios described above, the method provided by the exemplary implementation of the present application is described with reference to the accompanying drawings. It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present application, and the implementation of the present application is not limited in this respect. It should be noted that the following method can be executed by the above terminal device or server, or by the terminal device and the server together. Here, the execution of the terminal device is specifically shown as an example.

[0053] Figure 4 A flowchart schematically shows a method for processing a texture map in this exemplary embodiment, see Figure 4 As shown, the method can be executed by a terminal device, and the specific implementation process of the method is as follows: Step 401-Step 402:

[0054] Step 401: Obtain a target mask map, where the target mask map is composed of multiple continuous polygons.

[0055] Step 402, mapping the target mask map to the texture map to be processed, so as to rotate each texture in the texture map to be processed in the target direction based on the target mask map, and obtain a processed first target texture map; the texture map to be processed is formed by splicing one or more basic texture maps multiple times.

[0056] exist Figure 4In the provided technical solution, a target mask map is obtained, which is composed of multiple continuous polygons; the target mask map is mapped to the texture map to be processed, so as to rotate each texture in the texture map to be processed in the target direction based on the target mask map, and obtain the processed first target texture map; wherein, the texture map to be processed is formed by multiple splicing of at least one basic texture map. This method uses a target mask map with richer polygonal shapes to realize the rotation of the texture map to be processed in the target direction, and then distorts and divides the seamless map so that it does not contain repeated textures, thereby solving the technical problem of high texture repetition in the prior art and greatly improving the effect quality of the art scene. In addition, this method uses a target mask map with richer shapes, so that different texture effects can be achieved by using rich polygons, thereby improving the richness and randomness of the texture map, avoiding the technical problem of poor authenticity caused by the scene screen being exposed, and thus improving the user experience.

[0057] The following will be combined with specific embodiments to Figure 4 The specific implementation methods of each step in the embodiment shown are described in detail:

[0058] In step 401, a target mask map is obtained, where the target mask map is composed of a plurality of continuous polygons.

[0059] The target mask map is composed of a plurality of identical or different and continuous polygons, and the polygons may be any polygons such as triangles, quadrilaterals, pentagons, etc.

[0060] Before executing step 401, it is necessary to generate a target mask map in advance, which will be described below in conjunction with a specific embodiment.

[0061] Embodiment 1:

[0062] In an optional embodiment of the present disclosure, the target mask map can be formed based on a set of continuous polygons formed by the intersection of perpendicular bisectors connecting two discrete points, that is, based on connecting every two discrete points and drawing a perpendicular bisector of the connecting line, the intersection of each perpendicular bisector can obtain a continuous polygon.

[0063] In order to illustrate the process of generating the target mask map, the following will combine Figure 5A , Figure 5B , Figure 5C An exemplary description is given.

[0064] Step 1: Randomly generate multiple discrete points on a two-dimensional plane.

[0065] Reference Figure 5A As shown, a number of discrete points are randomly generated on a two-dimensional plane.

[0066] Then, step 2 is executed to generate a vertical extension line perpendicular to the connecting line through the midpoint position of the connecting line between each two discrete points.

[0067] Reference Figure 5B As shown, for every two discrete points, the midpoint position of the line connecting the two discrete points is taken, and a vertical extension line perpendicular to the line (i.e., the perpendicular bisector between the two discrete points) is generated through the midpoint position, and then multiple vertical extension lines can be generated for multiple discrete points.

[0068] Step 3: intersect each vertical extension line generated according to the plurality of discrete points to form a plurality of continuous polygons, and obtain a first target mask map.

[0069] For example, in step 2, corresponding perpendicular bisectors are generated for every two discrete points, and the process of step 2 is performed for all discrete points, so that multiple perpendicular extension lines can be obtained, and the intersection of the perpendicular extension lines will form multiple continuous polygons, so that the following can be obtained: Figure 5C The first target mask map is shown.

[0070] Embodiment 2:

[0071] In addition to the above embodiments, in another optional embodiment of the present disclosure, a plurality of discrete points are randomly generated on a two-dimensional plane, and a triangular network is constructed based on the plurality of discrete points; the center of the circumscribed circle of each triangle in the triangular network is determined; for each target triangle in the triangular network, if an adjacent triangle to the target triangle is found, the center of the circumscribed circle of the adjacent triangle is connected with the center of the circumscribed circle of the target triangle to obtain a first line, and the first line is stored in a line list; if an adjacent triangle corresponding to the target edge in the target triangle is not found, a second line perpendicular to the target edge is generated, and the second line is stored in a line list; a plurality of continuous polygons are constructed based on the lines in the line list to obtain a first target mask map.

[0072] The triangle network is a network structure composed of multiple triangles, the target triangle is any triangle in the triangle network, and the target edge is any edge in the target triangle. The adjacent triangle represents the triangle that has a common edge with the target triangle, that is, the triangle that shares the same triangle edge with the target triangle.

[0073] Each connection included in the connection linked list corresponds to the first connection and / or the second connection mentioned above. Through the connection linked list, each connection can be stored in the memory in a dispersed manner, and different connections point to the memory address where the next connection is located through pointers. This process does not require each connection to be stored in a continuous memory space, and then scattered storage resources can be fully utilized to improve the utilization rate of storage resources.

[0074] For the sake of convenience, the following will be combined Figure 6 The implementation steps of the above embodiment are exemplarily described as follows:

[0075] The specific steps are as follows: Step a), construct a triangular network based on a plurality of randomly generated discrete points. Figure 6 As shown in the first figure, multiple discrete points can be randomly generated on a two-dimensional plane, and then a structure such as Figure 6 The triangle network of the second figure is shown. Exemplarily, the triangle network is composed of multiple triangles, and the discrete points and the triangles formed by the discrete points can be numbered to record the three discrete points corresponding to each triangle.

[0076] It should be explained that the circumscribed circle of any triangle in the triangular network does not contain other discrete points. The advantages of the triangular network constructed by the above step a) are simple data structure, low data redundancy, high storage efficiency, easy update, and adaptability to data of various distribution densities.

[0077] Step b), calculate the center of the circumscribed circle of each triangle in the triangular network.

[0078] Step c), traverse the triangle linked list, and for each target triangle, search for adjacent triangles TriA, TriB and TriC that share three sides with the target triangle pTri.

[0079] Step d), if found, connect the center of the circumscribed circle of the found triangle with the center of the circumscribed circle of the target triangle pTri, and store the obtained first link in the link linked list.

[0080] On the contrary, if no adjacent triangle connected to the target edge of the target triangle pTri is found, step e) is executed to obtain a second connection line for the vertical extension line of the target edge, and the second connection line is stored in the connection list. The second connection line can be a vertical bisector of the target edge, that is, a vertical extension line is made for the midpoint position of the target edge.

[0081] Step f), traverse all triangles and execute the above steps b) to e), and complete the traversal for all triangles, so that all the links in the link list are found, and then the first target mask map can be constructed according to all the links in the link list. At this time, the first target mask map is composed of multiple continuous polygons.

[0082] Through the above-mentioned embodiments, a polygonal effect with richer mask shapes can be generated. Compared with the rectangular mixed mask used in the related technical scheme, the target mask map formed by multiple continuous polygons is used to facilitate different rotation effects of the processed texture map in mask areas of different shapes, thereby improving the texture richness and randomness.

[0083] In step 402, the target mask map is mapped to the texture map to be processed, so as to rotate each texture in the texture map to be processed in a target direction based on the target mask map, thereby obtaining a processed first target texture map.

[0084] Among them, the texture map to be processed can be a texture map on the surface of the target virtual model, and the target virtual model can be a model to be rendered in the virtual scene (for example, a surface model in the virtual scene, and the corresponding texture map to be processed is a grass texture map on the surface model). The virtual scene can be a game screen design scene involving the generation of random textures in a large area in the field of computer technology and image processing. The game type corresponding to the game screen design scene can be of any type, for example, action (for example: first-person or third-person shooting games, two-dimensional or three-dimensional fighting games, war action games and sports action games, etc.), adventure (for example: exploration games, collection games, puzzle games, etc.), simulation (for example: simulation sandbox games, simulation development games, strategy simulation games, city construction simulation games, business simulation games, etc.), role-playing and leisure (for example: chess and card table games, casual competitive games, music rhythm games, dress-up development games, etc.), etc., and the embodiments provided in the present disclosure do not impose any special restrictions on this.

[0085] The texture map to be processed is formed by splicing at least one basic texture map multiple times. Therefore, the texture map to be processed must have a high degree of texture repetition. The above-mentioned basic texture map can be a pre-configured texture map, and the texture map to be processed of the above-mentioned virtual model can be generated by at least one basic texture map. For example, the basic texture map can be Figure 1A The four-sided continuous map shown in Figure 1A The basic texture map shown is repeatedly arranged to obtain Figure 1B The texture map shown is to be processed.

[0086] It should be noted that, in order to enhance the randomness of the texture map to be processed, multiple basic texture maps can be pre-selected, and the texture map to be processed can be obtained by repeatedly arranging the multiple basic texture maps. In this embodiment, the multiple basic texture maps can be different texture maps of the same type, such as multiple different grass texture maps, or multiple different sand texture maps.

[0087] Exemplarily, the terminal device may segment and map the target mask map into the texture map to be processed, that is, map the target mask map to the location information (location) and rotation information (rotation) of the texture map to be processed, thereby rotating a specific texture on the texture map to be processed based on the location information.

[0088] It should be explained that texture mapping contains three attributes: location, rotation, and scale. By adjusting the parameter values ​​of the above three attributes, the texture mapping can be matched with the layer of the virtual model. Among them, location represents the center point of the entire map; rotation represents rotating the map. Generally, it is not necessary to change the x and y angles, but only the rotation angle on the z axis; and scale represents stretching the map. Generally, it is not necessary to adjust the value in the z axis direction, but to adjust the values ​​in the x and y axes.

[0089] In an optional embodiment of the present disclosure, when the target virtual model is a two-dimensional virtual model, the target direction is the Z-axis direction; when the target virtual model is a three-dimensional virtual model, the target direction is the X-axis direction, and / or the Y-axis direction, and / or the Z-axis direction.

[0090] Exemplarily, for the texture map on the surface of the two-dimensional virtual model, when executing the step of rotating each texture in the texture map to be processed based on the target mask map, only the twisting rotation in the Z-axis direction (i.e., the normal direction perpendicular to the two-dimensional plane) can be realized. For the texture map on the surface of the three-dimensional virtual model, when executing the step of rotating each texture in the texture map to be processed based on the target mask map, the twisting rotation can be performed in a single direction of the three-dimensional X-axis (left-right direction), Y-axis (front-back direction), and Z-axis (up-down direction) or in a combination of the above multiple directions (for example, only rotating in the X-axis and Y-axis directions) to obtain the processed first target texture map.

[0091] It should be explained that before executing the above embodiment to map the target mask map to the rotation information (rotation) of the texture map to be processed, the mapping information in the target direction can be pre-added, so that each texture in the texture map to be processed can be rotated in the target direction based on the target mask map, and then the processed first target texture map is obtained. For example, if it is necessary to perform a rotation in the Z-axis direction, the mapping in the Z-axis direction is pre-added before mapping the target mask map to the rotation information (rotation) of the texture map to be processed. If it is necessary to perform a rotation in the X, Y, and Z-axis directions for the texture map on the three-dimensional virtual model, the mapping in the X, Y, and Z-axis directions is pre-added.

[0092] Furthermore, based on the above-mentioned embodiment of obtaining the first target mask map, the first target mask map is usually a color image with RGB color information, and in the process of rotating each texture in the texture map to be processed in the target direction based on the first target mask map, there is no need to use the RGB color information. In order to reduce the amount of data processing and save computing resources, the first target mask map can be decolorized (i.e., grayscale processed) and only the brightness value of each pixel in the first target mask map is retained.

[0093] In an optional embodiment, the first target mask map is grayscaled to obtain a second target mask map; the second target mask map is mapped to the texture map to be processed in step 402, and each texture in the texture map to be processed is rotated in a target direction based on the second target mask map to obtain a processed first target texture map.

[0094] Through the grayscale processing, the color information in the first target mask map can be removed, and only the brightness value of each pixel in the map is retained, thereby obtaining the second target mask map.

[0095] Exemplarily, when grayscale processing is performed, a multiplication transformation (Multiply) may be performed on each pixel value of the first target mask map. The principle is to directly multiply images of different spatial resolutions with corresponding pixel grayscale values ​​to obtain grayscale values ​​of each pixel corresponding to the image.

[0096] In addition to the above embodiments, any other method may be used for grayscale processing, and the embodiments of the present disclosure do not impose any special restrictions on this. For example, decolorization processing may also be performed by training a neural network model. For example, multiple color image samples and grayscale images corresponding to each color image sample are obtained; and the multiple color image samples are input into the image processing model to obtain a predicted grayscale image corresponding to each color image sample.

[0097] In the above Figure 5C Based on the first target mask map shown in FIG. 1 , a second target mask map is obtained by graying the first target mask map. Figure 7 As shown in FIG. 1 , the color information of the first target mask map is removed from the second target mask map, and only the brightness value of the image is retained. Figure 7 The second target mask map is mapped to Figure 2A The location and rotation attributes of the texture map to be processed are shown in Figure 2A Each texture of the location parameter instruction in the texture map to be processed is rotated in the target direction, and the rotation angle is determined by the rotation parameter value, thereby obtaining Figure 8Shown is the first target texture map after processing.

[0098] Depend on Figure 8 It can be seen that the processed first target texture map effectively removes repeated textures in the texture map compared to the texture map before processing, thereby reducing the texture repetition in the texture map, so as to further meet the needs and quality of scene production.

[0099] In the process of generating the first target mask map in any of the above embodiments, the user may also adjust the pixel values ​​of the second target mask map to adjust the shapes of the polygons in the second target mask map, thereby adjusting the overall display effect of the second target mask map.

[0100] In an optional embodiment of the present disclosure, in response to adjusting the pixel values ​​of the second target mask map, the rotation parameters of each texture in the texture map to be processed are adjusted in the target direction based on the adjusted second target mask map.

[0101] Exemplarily, the user may also adjust the pixel values ​​of the second target mask map to control the adjustment of the rotation parameters, thereby achieving different rotation effects.

[0102] Fig. 9A , Fig. 9B FIG. 1 shows a schematic diagram of different effects displayed after adjusting the pixel value of the second target mask map in this exemplary embodiment; FIG. Fig. 9A , Fig. 9B As shown, by adjusting the pixel values ​​of the second target mask map, the shapes of multiple polygons in the second target mask map can be changed, thereby achieving different rotation effects and improving texture richness.

[0103] Furthermore, in the first target texture map obtained based on any of the above embodiments, when the distance between the virtual camera and the texture map on the target virtual model is shortened, it is found that there are still obvious layers or seams on the segmented edges. Figure 8 The first target texture map shown is reduced in distance from the virtual camera and can be seen as Fig.10 Layering shown.

[0104] In an optional embodiment of the present disclosure, for each continuous polygon of the target mask map, the brightness value is changed from dark to light toward the inside of the polygon based on the edge position of the continuous polygon to obtain a third target mask map; the color scale of the third target mask map is adjusted to the target color scale value to obtain a fourth target mask map, the target color scale value is the same as the color scale value of the texture map to be processed or the difference between the target color scale value and the color scale value of the texture map to be processed is less than a preset quantity threshold; the fourth target mask map is implicitly mapped to the texture map to be processed to obtain a processed second target texture map.

[0105] For example, when the layering at the splicing is processed, Figure 7 Based on the second target mask map shown in FIG. 1 , the brightness value of the continuous polygon edge position can be changed from dark to bright inside the polygon to obtain a reference Fig.11A The third target mask map is shown.

[0106] Then, adjust the color level of the third target mask map to the target color level value, and get Fig. 11B Finally, based on Fig.12 Will Fig. 11B The fourth target mask map shown is mapped to the texture map to be processed, and the processed second target texture map can be obtained, thereby obtaining Fig.13 The second target texture map is shown.

[0107] Depend on Fig.13 It can be seen that the masked part texture of the processed second target texture map segmented by polygons is always seamlessly connected and has low repetition, which greatly improves the effect quality of the art scene.
