[0029] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the principles and spirit of the present disclosure will be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0030] It should be understood herein that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction rather than having any limiting meaning.

[0031] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connecting" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The article "one" or "a" before an element does not exclude the existence of multiple such elements.

[0032] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure.

[0033] In video games, a skill warning box refers to a user interface (UI) element that helps players better understand and respond to the release of skills in the game through different shapes and animation effects. For example, it helps players predict the attack range of skills so that they can respond accordingly, such as dodging or preparing for a counterattack.

[0034] In specific implementation, the skill warning box can have a variety of shapes, including rectangular, circular, and fan-shaped, etc. The solution provided in the present disclosure is mainly aimed at the rectangular skill warning box.

[0035] In the related art, in the process of rendering a rectangular skill warning box, in order to improve the display effect of the skill warning box, such as improving its resolution to make it look more realistic and refined, it is usually necessary to use a large-size texture.

[0036] However, the inventors of the present disclosure have discovered that the use of large-size textures not only requires a large amount of storage space, which significantly increases the storage burden of the device, but also significantly increases the computing burden of the device during the graphics rendering process, thereby affecting performance and response speed.

[0037] Since it will significantly increase the storage and computing burden of the device, the solution of using large-size textures is obviously not applicable to mobile devices and low-power devices where resource constraints are more prominent.

[0038] In order to solve the above problems, the present disclosure provides a graphics rendering solution, which specifically includes: determining a rectangular box map to be sampled; determining a corner area and an edge non-corner area of ​​the rectangular box map to be sampled; sampling the edge non-corner area to obtain an edge non-corner area texture map, and repeatedly mapping the edge non-corner area texture map to a target model; sampling the corner area to obtain a corner area texture map, and mapping the corner area texture map to the target model.

[0039] The present invention repeatedly maps texture maps of edge non-corner areas to the target model, so that only low-resolution maps need to be stored and sampled to achieve the graphics rendering effect that can only be achieved by storing and sampling high-resolution maps, thereby reducing storage space occupancy; reducing the computational burden during graphics rendering, and improving performance and response speed.

[0040] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0041] refer to Figure 1 , which is a schematic diagram of an application scenario of the graphics rendering method provided by an exemplary embodiment of the present disclosure.

[0042] This application scenario includes a terminal device 101.

[0043] The terminal device 101 may be an electronic device with data transmission and multimedia input / output functions close to the user side, including but not limited to a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA) or other electronic devices capable of realizing the above functions. The electronic device may include a processor and a display screen with a touch input function, the display screen is used to present a graphical user interface, the graphical user interface can display an application interface, and the processor is used to process application data, generate a graphical user interface, and control the display of the graphical user interface on the display screen.

[0044] In some exemplary embodiments, the graphics rendering method may be executed on the terminal device 101 .

[0045] When the graphics rendering method runs on the terminal device 101, the terminal device 101 is used to provide graphics rendering services to the user of the terminal device 101. A client is installed in the terminal device 101, and the client provides a graphical user interface. The content displayed by the graphical user interface includes a game scene with virtual objects. The game scene is a virtual scene displayed (or provided) when the application is running on the terminal.

[0046] The user can control the controlled virtual object in the virtual scene through the client. The user can control the controlled virtual object to move in the virtual scene, for example, control the controlled virtual object to navigate or collect virtual resources, etc., and can also control the controlled virtual object to upgrade and develop on the building object created by itself, and can also control the controlled virtual object to fight with virtual objects of other camps. Optionally, the controlled virtual object can have multiple functions, such as not only the function of collecting virtual resources, but also the function of fighting.

[0047] The controlled virtual objects in the virtual scene also include artificial intelligence (AI) set in the virtual environment through training.

[0048] As a specific example, see Figure 2 In the virtual scene 200, when the first virtual character 201 attacks the second virtual character 202, in order to help the player better understand and respond to the skill release in the game, a skill warning box 203 is provided to help the player controlling the second virtual character 202 predict the attack range of the skill of the first virtual character 201 so as to make corresponding responses, such as dodging or preparing to counterattack.

[0049] In specific implementation, the terminal device 101 determines the rectangular frame map to be sampled; determines the corner area and edge non-corner area of ​​the rectangular frame map to be sampled; samples the edge non-corner area to obtain the edge non-corner area texture map, and repeatedly maps the edge non-corner area texture map to the target model; samples the corner area to obtain the corner area texture map, and maps the corner area texture map to the target model. The client displays the rectangular frame mapped to the target model to the user (as a skill warning frame) to help players better understand and respond to the release of skills in the game. For example, it helps players predict the attack range of skills so that they can make corresponding responses, such as dodging or preparing to counterattack.

[0050] Combine the following Figure 1 and Figure 2 The graphics rendering method according to the exemplary embodiment of the present disclosure is described by using the application scenario. It should be noted that the above application scenario is only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0051] refer to Figure 3 , which is a flow chart of a mapping processing method provided by an exemplary embodiment of the present disclosure.

[0052] The mapping method comprises the following steps:

[0053] Step S310: Determine the rectangular frame map to be sampled.

[0054] In this exemplary embodiment, the to-be-sampled rectangular frame map refers to the state of the rectangular frame map before being rendered onto the model surface, and correspondingly, the sampled rectangular frame map refers to the state of the rectangular frame map after being rendered onto the model surface.

[0055] In specific implementation, the unsampled rectangular frame map refers to the state of the texture map before it is read by the sampler and applied to the surface of the object during the graphics rendering process. The map in this state is the original image data without any transformation or processing. At this stage, the UV coordinates of the map have not been calculated, and the filtering and addressing mode of the texture have not been applied. The unsampled rectangular frame map is the input in the rendering pipeline, waiting to be read by the sampler and converted into a sampled rectangular frame map.

[0056] The sampled rectangle map is the state of the texture map after it has been processed by the sampler and applied to the surface of the object. At this stage, the UV coordinates of the texture have been calculated, and according to the settings of the sampler (such as filtering method and addressing mode), the pixel values ​​of the texture are interpolated or adjusted to fit the geometry of the surface of the object. The sampled rectangle map is the output of the rendering pipeline, which reflects the texture effect that will be displayed on the screen.

[0057] The rectangular frame map to be sampled is the original state of the texture data, and the rectangular frame map after sampling is the final state combined with the surface of the object after being processed by the sampler.

[0058] In this exemplary embodiment, the resolution of the rectangular frame map to be sampled is a first resolution, and the resolution of the rectangular frame map after sampling is a second resolution, wherein the first resolution is lower than the second resolution.

[0059] In a specific implementation, the rectangular frame map to be sampled is a map with a lower resolution, wherein the lower resolution means that the resolution of the rectangular frame map to be sampled is lower than that of the sampled rectangular frame map.

[0060] As a specific example, the resolution of the rectangular frame map to be sampled is 128*128 pixels or 256*256 pixels, and the resolution of the rectangular frame map after sampling is 1024*1024 pixels or 2048*2048 pixels.

[0061] Here, taking the resolution of the rectangular frame map to be sampled as 256*256 pixels as an example, it means that the width and height of the rectangular frame map to be sampled are both 256 pixels.

[0062] In this exemplary embodiment, determining the rectangular frame map to be sampled includes:

[0063] Get the rectangular frame map to be sampled from the local computer.

[0064] In specific implementation, since the resolution of the rectangular frame map to be sampled adopted in the present disclosure is relatively low, the storage space occupied is reduced. Therefore, compared with the related technology, it is more suitable for storage in the terminal device locally, which can reduce the transmission delay.

[0065] Through this exemplary embodiment, only low-resolution textures need to be stored and sampled to achieve the effect that can only be achieved by storing and sampling high-resolution textures. This reduces the storage space occupied; reduces the computational burden during graphics rendering, and improves performance and response speed. Furthermore, it reduces the demand for hardware and can be used in mobile devices and low-power devices.

[0066] Step S320: Determine the corner area and edge non-corner area of ​​the rectangular frame map to be sampled.

[0067] In this exemplary embodiment, the rectangular frame map to be sampled is divided into a plurality of regions;

[0068] The corner region and the edge non-corner region among the plurality of regions are determined.

[0069] As a specific example, see Figure 4 , which is a schematic diagram of an exemplary rectangular frame map to be sampled, refer to Figure 5 , dividing the rectangular frame map to be sampled into a nine-square grid layout.

[0070] Among them, there are nine areas: 1, 2, 3, 4, 5, 6, 7, 8 and 9.

[0071] Based on the layout of the nine-grid, the corner area and the edge non-corner area of ​​the rectangular frame map to be sampled are determined.

[0072] Among them, 1, 3, 7 and 9 are corner areas;

[0073] 1, 2, 3, 4, 6, 7, 8, and 9 are marginal areas;

[0074] 2, 4, 6 and 8 are edge non-corner areas.

[0075] In the above exemplary embodiments, the layout of dividing the rectangular frame map to be sampled into a nine-grid layout is taken as an example for description. However, in some application scenarios, the texture of the rectangular frame map to be sampled is relatively complex. In this case, in order to improve the display effect of the sampled rectangular frame map obtained after executing step S330 and step S340, the following exemplary embodiments are provided, specifically:

[0076] In this exemplary embodiment, dividing the rectangular frame map to be sampled into a plurality of regions includes:

[0077] Determine the minimum repeating unit in the rectangular frame map to be sampled;

[0078] Based on the minimum repeating unit, the rectangular frame map to be sampled is divided into the multiple areas.

[0079] In specific implementation, the minimum repeating unit refers to the minimum repeating unit that constitutes a complex pattern or texture in the rectangular frame map to be sampled. This unit can generate the entire pattern through symmetry operations (such as rotation, reflection, etc.).

[0080] Through the above exemplary embodiments, based on the minimum repeating unit, it can be ensured that the texture of the sampled rectangular frame map obtained after executing step S330 and step S340 can be spliced ​​in the corresponding direction, thereby improving the display effect.

[0081] Step S330: sampling the edge non-corner area to obtain an edge non-corner area texture map, and repeatedly mapping the edge non-corner area texture map to the target model.

[0082] In a specific implementation, the smaller edge non-corner area texture map is repeatedly mapped to the target model along the horizontal direction or the vertical direction to create a larger texture effect without actually having a larger texture map.

[0083] In this exemplary embodiment, sampling the edge non-corner area to obtain an edge non-corner area texture map, and repeatedly mapping the edge non-corner area texture map to the target model includes:

[0084] Determine a first edge non-corner area texture map to be repeatedly mapped along the horizontal direction among the edge non-corner area texture maps;

[0085] Repeating mapping the first edge non-corner area texture map to the target model a first preset number of times in the horizontal direction;

[0086] Determine a second edge non-corner area texture map to be repeatedly mapped along the vertical direction in the edge non-corner area texture map;

[0087] The second edge non-corner area texture map is repeatedly mapped a second preset number of times along the vertical direction to the target model.

[0088] As a specific example, see Figure 6 , among which, compared with Figure 5 The edge non-corner area texture maps corresponding to edge non-corner areas 2 and 8 are repeatedly mapped to the target model 4 times along the horizontal direction; the edge non-corner area texture maps corresponding to edge non-corner areas 4 and 6 are repeatedly mapped to the target model 4 times along the vertical direction.

[0089] Step S340: Sampling the corner area to obtain a corner area texture map, and mapping the corner area texture map to the target model.

[0090] In this exemplary embodiment, sampling the corner area to obtain a corner area texture map, and mapping the corner area texture map to the target model includes:

[0091] Determine a corner gap area formed after repeatedly mapping the edge non-corner area texture map to the target model;

[0092] The corner area texture maps are respectively mapped to the corner gap areas on the target model.

[0093] As a specific example, see Figure 6 , map the corner area texture maps corresponding to corner areas 1, 3, 7 and 9 to the target model.

[0094] During specific implementation, step S330 and step S340 are performed simultaneously.

[0095] Through the above exemplary embodiments, the texture map of the edge non-corner area repeatedly mapped to the target model and the texture map of the corner area mapped to the target model are spliced ​​to form a sampled rectangular frame map.

[0096] Furthermore, the inventors of the present disclosure have discovered that because the GPU does not render pixel by pixel but rather four pixels at a time, defects may occur when the four pixels jump too much left / right / up / down. Figure 6 In the example, pixels at the edge where the corner area 1 and the edge non-corner area 2 meet may have defects such as flickering / error display. To solve this defect, the present disclosure provides the following exemplary embodiments, specifically:

[0097] In this exemplary embodiment, after sampling the corner area to obtain a corner area texture map and mapping the corner area texture map to the target model, the method further includes:

[0098] Determine a change rate between edge pixels of the edge non-corner area texture map and edge pixels of the adjacent corner area texture map after being mapped to the target model;

[0099] In response to determining that the change rate is greater than a preset change rate threshold, edge pixels of the edge non-corner area texture map and / or edge pixels of the corner area texture map are cut off.

[0100] In specific implementation, the DDX and DDY functions are used to calculate the change rate of the variable in the pixel block in the screen space, where DDX is horizontal and DDY is vertical. When the change rate is too large, the content is cut off, that is, it is not displayed at all.

[0101] As a specific example, if the value of DDX or DDY exceeds the change rate threshold of 0.3, it will not be displayed, thereby avoiding the occurrence of flickering defects.

[0102] In specific implementation, after the sampled rectangular frame map is used, the sampled rectangular frame map is not saved locally, and the locally saved is still the to-be-sampled rectangular frame map, which reduces the storage space occupied.

[0103] From the above, it can be seen that the graphics rendering method provided by the embodiment of the present disclosure includes: determining a rectangular frame map to be sampled; determining a corner area and an edge non-corner area of ​​the rectangular frame map to be sampled; sampling the edge non-corner area to obtain an edge non-corner area texture map, and repeatedly mapping the edge non-corner area texture map to a target model; sampling the corner area to obtain a corner area texture map, and mapping the corner area texture map to the target model.

[0104] The present invention repeatedly maps texture maps of edge non-corner areas to the target model, so that only low-resolution maps need to be stored and sampled to achieve the graphics rendering effect that can only be achieved by storing and sampling high-resolution maps, thereby reducing storage space occupancy; reducing the computational burden during graphics rendering, and improving performance and response speed.

[0105] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.

[0106] It should be noted that the above describes some embodiments of the present disclosure. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
