Description

Technical Field

[0001] The present disclosure relates to the field of computer technologies, and in particular, to a texture rendering method, apparatus, medium, electronic device, and program product. Background Art

[0002] In a game scene, decals are generally used to make the game scene more realistic and vivid. For example, in a game scene, decals can be used to achieve effects such as bullet holes and stickers. In the related art, dynamic decals or static decals can generally be used to draw decals in a game scene. For dynamic decals, the scene depth needs to be used, and the OverDraw is relatively high. Especially when a large number of decals are drawn, it will cause a greater impact on the performance of the device. Static decals are pre-rendered and cannot be changed arbitrarily during operation. If the decals are refreshed, the static decals need to be re-rendered, and the rendering overhead is not less than that of dynamic decals. Therefore, the related art cannot provide a texture rendering technology that can be dynamically refreshed and can also take into account the running performance of the device. Summary of the Invention

This Summary of the Invention section is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to be used to limit the scope of the claimed technical solution.

[0004] In a first aspect, the present disclosure provides a texture rendering method, including: responding to an event for triggering an event texture change of a target virtual object in a virtual scene, and determining a target tile where the event texture change of the target virtual object occurs; updating texture data corresponding to the target tile in the virtual texture of the target virtual object based on the event texture after the change of the target tile, to obtain an updated virtual texture; displaying the target virtual object based on the updated virtual texture.

[0023] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0024] It should be understood that the steps recited in the method embodiments of the present disclosure can be executed in a different order and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this regard.

[0025] As used herein, the term "including" and its variants are open-ended, that is, "including but not limited to". The term "based on" is "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0026] It should be noted that concepts such as "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or mutual dependence relationship of the functions performed by these devices, modules or units.

[0027] It should be noted that the modification of "one" and "multiple" mentioned in this disclosure is illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0028] The names of the messages or information exchanged between multiple devices in the embodiments of this disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0029] Figure 1 It is a schematic diagram of a tile shown according to an exemplary embodiment. As Figure 1 shown, for the terrain in a game scene, from the perspective of a given virtual camera, the entire terrain is divided into individual tiles, and each Tile is equivalent to a plot unit.

[0030] The size of the Tile and the mip level (the multi-level progressive version of the texture) are related to the distance from the virtual camera. The closer the Tile, the lower the mip level, the higher the corresponding precision, and the smaller the coverage range. The farther the Tile, the higher the mip level, the lower the corresponding precision, and the larger the coverage range.

[0031] Figure 2 It is a flowchart of tile texture update shown according to an exemplary embodiment. As Figure 2 shown, for the update of each plot unit (tile), according to the terrain material of the terrain, the corresponding terrain texture is mixed, and then, on the basis of the terrain texture, the pixels of the corresponding decals are sequentially superimposed in the order of the number of decal layers on the Tile to obtain a complete terrain with decals.

[0032] When all the Tiles displayed on the screen need to be refreshed, the GPU (Graphics Processing Unit) resources consumed are very large. Therefore, when updating the terrain's Runtime Virtual Texture (RVT), considering the impact on running efficiency, it is usually updated frame by frame. That is to say, first update the Tiles with a higher mip level, and then update the Tiles with a lower mip level. In this way, during actual updates, players can clearly see the loading process of the game scene from blurred to clear, especially when there is a large-scale update of the terrain, which will be more incongruous. Therefore, in related technologies, a transition loading interface or transition special effects are usually used to block this loading process, and after the update is completed, the updated terrain is shown to the user.

[0033] Figure 3 is an effect diagram showing frame-by-frame update according to an exemplary embodiment. As Figure 3 shown, from the first frame to the third frame to the fifth frame to the ninth frame, the terrain gradually becomes clear from blurred.

[0034] In this regard, if there is a decal change in the terrain, the terrain's Runtime Virtual Texture is updated. When there are frequent decal changes in the game scene, it will result in huge and unacceptable performance consumption. Moreover, when there is a large-scale update of the Runtime Virtual Texture, there will be a relatively obvious loading process. If the Runtime Virtual Texture is continuously refreshed during the game process, the terrain will keep changing between blurred and clear.

[0035] Based on the above technical problems, the embodiments of the present disclosure provide a texture rendering method, which can not only support the dynamic refresh of event textures in the game scene while taking into account the running performance of the device to achieve the effect of dynamically changing the game scene, but also there will be no obvious loading process.

[0036] The following will describe in detail the texture rendering method proposed in the embodiments of the present disclosure with reference to the accompanying drawings.

[0037] Figure 4 is a flowchart of a texture rendering method according to an exemplary embodiment. As Figure 4 shown, the embodiments of the present disclosure provide a texture rendering method, which can specifically be executed by a texture rendering device, and this device can be implemented in a software and / or hardware manner and configured in an electronic device. As Figure 4 shown, the method may include the following steps.

[0038] In step 410, in response to an event for triggering an event texture change of a target virtual object in the virtual scene, determine the target tile where the event texture change of the target virtual object occurs.

[0039] Here, the target virtual object in the virtual scene can be the terrain, walls, etc. in the virtual scene. That is to say, the texture rendering method provided by the embodiments of the present disclosure can be applicable to both the event texture rendering of the terrain and the event texture rendering of the walls.

[0040] The event texture can refer to a kind of texture in the virtual scene. The event texture can be a texture newly added to the original texture of the target virtual object, and the event texture can be triggered by an event triggered in the virtual scene. Exemplarily, the event texture can refer to a decal. Decals are used to add patterns or specific materials to the surface of an object, and these patterns or materials can interact with the lighting in the virtual scene and produce realistic effects. It should be understood that the event texture can be used to achieve some special effects, such as bullet holes, bloodstains, marks, etc., to enhance the visual performance and immersion of the game. The occurrence of event texture change of the target virtual object in the virtual scene can refer to the increase or deletion of the event texture of the target virtual object.

[0041] It should be noted that the occurrence of event texture change of the target virtual object in the virtual scene is triggered by an event in the game. For example, when a virtual bomb explodes on the ground, a crater texture mark will be left on the ground. Another example is that when a virtual bullet hits the wall, a bullet hole texture mark will be left on the wall.

[0042] When detecting an event for triggering the event texture change of the target virtual object in the virtual scene, the electronic device determines the target tile where the event texture change of the target virtual object occurs. Here, a tile is an image block used to compose the target virtual object. For example, taking the terrain as an example, the terrain is cut into individual tiles, and each tile is equivalent to a plot unit.

[0043] It should be understood that the target tile where the event texture change of the target virtual object occurs refers to the tile where there is an increase or deletion of the event texture on the target virtual object. For example, when adding a layer of event texture to a certain area on the terrain, the tiles intersected by the event texture in this area are the target tiles.

[0044] It should be noted that the target tiles where the event texture change occurs can be determined before the rendering of each frame of the picture starts.

[0045] In step 420, based on the event texture after the change of the target tile, the texture data corresponding to the target tile in the virtual texture of the target virtual object is updated to obtain the updated virtual texture.

[0046] Here, the event texture after the target tile change may refer to the event texture currently still included on the target tile. For example, the event texture after the target tile change refers to all the event textures superimposed on the target tile. The virtual texture (VT) of the target virtual object is texture data formed through a graphics processing technology, aiming to optimize the memory usage and rendering performance of large scenes. By dynamically loading and unloading texture data, virtual textures load part of the texture data into memory when needed, thus achieving the effective utilization of huge texture sets.

[0047] It should be understood that when the types of target virtual objects are different, the types of virtual textures corresponding to the target virtual objects may also be different.

[0048] When the target virtual object is terrain, the virtual texture of the target virtual object is the runtime virtual texture (RVT). RVT is a texture management system that allows for the dynamic loading, updating, and management of texture data at runtime. By storing texture data in virtual memory and dynamically loading it into video memory as needed, RVT optimizes memory usage and rendering performance.

[0049] When the target virtual object is a wall, the virtual texture of the target virtual object is the streaming virtual texture (SVT). The streaming virtual texture is texture data formed through a texture streaming technology, aiming to optimize the memory usage and rendering performance of high-resolution textures in large scenes. SVT reduces memory occupancy and bandwidth consumption by splitting texture data into small pages (equivalent to tiles) and dynamically loading these pages into video memory as needed.

[0050] When the event texture of the target tile of the target virtual object changes, the texture data corresponding to the target tile in the virtual texture is updated to obtain the updated virtual texture. That is to say, for the virtual texture of the target virtual object, when the event texture of the target virtual object changes, the texture of the image block corresponding to the target tile on the virtual texture is locally updated, rather than updating the entire virtual texture again. Therefore, based on the virtual texture, by locally updating the texture data with event texture changes, the dynamic update ability of event textures can be achieved at a relatively small performance cost, thus supporting the dynamic refresh of event textures in game scenes while taking into account the device's operability. Especially on mobile terminals, it can support the rendering of a large number of event textures and the dynamic update of event textures.

[0051] It should be noted that when the event texture of the target virtual object changes again, the texture data of the target tile whose event texture changes currently is updated on the updated virtual texture. That is to say, only one virtual texture of the target virtual object needs to be maintained. When the event texture of the target virtual object changes, the texture data of the image block whose event texture changes in the virtual texture is updated.

[0052] In step 430, the target virtual object is displayed based on the updated virtual texture.

[0053] Here, the updated virtual texture can be rendered onto the target virtual object, so as to display the rendered target virtual object.

[0054] Thus, by determining the target tile whose event texture of the target virtual object changes, and based on the event texture after the change of the target tile, updating the texture data corresponding to the target tile in the virtual texture of the target virtual object to obtain the updated virtual texture, and then displaying the target virtual object based on the updated virtual texture, not only can the dynamic update ability of the event texture be realized with a small performance cost by locally updating the texture data whose event texture changes on the basis of the virtual texture, but also the event texture in the game scene can be supported to be dynamically refreshed while taking into account the running performance of the device. Especially on mobile terminals, it can support the rendering of a large number of event textures and the dynamic update of event textures.

[0055] It should be noted that rendering event textures (decals) through virtual textures generally can support the rendering of a large number of event textures. However, since real-time updating of virtual textures will cause excessive performance consumption, the event textures rendered through virtual textures generally cannot be dynamically updated. Through the texture rendering method provided by the embodiments of the present disclosure, the event textures that cannot be dynamically updated can be made to be dynamically updated, and the consumed performance is small.

[0056] Figure 5 Yes Figure 4 The detailed flowchart of step 420 shown is as follows. As Figure 5 shown, in some implementable embodiments, step 420 may include the following steps.

[0057] In step 421, according to the texture change type corresponding to the target tile, the first texture data corresponding to the target tile is obtained from the cache pool or the virtual texture corresponding to the target virtual object.

[0058] Here, the texture change types corresponding to the target tile may include a first texture change type for characterizing the addition of event textures on the target tile and a second texture change type for characterizing the deletion of event textures on the target tile. The first texture change type means that, based on the event textures originally included in the target tile, one or more layers of event textures are superimposed. The second texture change type means that, based on the event textures originally included in the target tile, one or more layers of event textures are deleted.

[0059] For different types of texture change types, the first texture data corresponding to the target tile can be obtained from the cache pool or the virtual texture corresponding to the target virtual object. For example, for the first texture change type, the first texture data corresponding to the target tile can be obtained from the virtual texture corresponding to the target virtual object. For the second texture change type, the first texture data corresponding to the target tile can be obtained from the cache pool.

[0060] Among them, the cache pool is used to cache the texture data of the virtual texture that does not contain event textures of the target virtual object. It should be understood that the cache pool can cache the texture data of the virtual texture corresponding to each Tile.

[0061] Figure 6 is a schematic diagram of drawing a virtual texture shown according to an exemplary embodiment. As Figure 6 shown, the runtime virtual texture corresponding to the terrain can be mixed according to the terrain material of the terrain. The runtime virtual texture at this time contains the terrain material but does not contain event textures. The obtained runtime virtual texture is not only written into the physical map, but also an additional cache pool is opened to cache the texture data of each tile of the runtime virtual texture. Therefore, the cache pool caches the original texture data of the virtual texture that does not contain event textures of the target virtual object.

[0062] In step 422, based on the event texture and the first texture data after the change of the target tile, the second texture data corresponding to the target tile is obtained.

[0063] Here, after obtaining the first texture data corresponding to the target tile from the cache pool or the virtual texture corresponding to the target virtual object, the second texture data corresponding to the target tile can be obtained based on the event texture and the first texture data after the change of the target tile.

[0064] For example, for the first texture change type, the newly added event texture can be superimposed on the first texture data to obtain the second texture data. For the second texture change type, the remaining event texture of the target tile can be superimposed on the first texture data to obtain the second texture data.

[0065] It should be noted that the second texture data of the target tile may refer to the texture data after the event texture of the target tile has changed. It is worth noting that by using the first texture data obtained from the cache pool or the virtual texture of the target virtual object to generate the second texture data, there is no need to regenerate the texture data of the target tile through the material, thereby further reducing performance consumption.

[0066] In step 423, update the second texture data to the position corresponding to the target tile in the virtual texture of the target virtual object to obtain the updated virtual texture.

[0067] Here, after obtaining the second texture data, update the second texture data to the position corresponding to the target tile in the virtual texture of the target virtual object to locally update the image block where the event texture of the virtual texture of the target virtual object has changed, and obtain the updated virtual texture.

[0068] Thus, through the above implementation, the tiles in the virtual texture where the event texture has changed can be updated based on the existing first texture data, without having to regenerate the texture data of the target tile through the material, thereby further reducing performance consumption.

[0069] In some implementable embodiments, in step 421, when the texture change type corresponding to the target tile indicates the addition of an event texture on the target tile, the first texture data corresponding to the target tile can be obtained from the virtual texture of the target virtual object. Correspondingly, in step 422, the added event texture can be superimposed on the first texture data to obtain the second texture data corresponding to the target tile.

[0070] Here, when the texture change type corresponding to the target tile is the first texture change type, directly copy the first texture data corresponding to the target tile from the virtual texture of the target virtual object to the RenderTarget (rendering target), and then, on the basis of the first texture data, superimpose and draw the added event texture to obtain the second texture data corresponding to the target tile.

[0071] It is worth noting that when the texture change type corresponding to the target tile indicates the addition of an event texture on the target tile, in fact, one or more layers of added event textures are drawn on the original texture data of the target tile, so the first texture data of the target tile can be copied from the virtual texture of the target virtual object.

[0072] Figure 7 is a schematic diagram of updating a virtual texture shown according to an exemplary embodiment. As Figure 7As shown in the figure, taking the event texture as a decal as an example, the first texture data corresponding to the target tile 702 can be copied from the runtime virtual texture 701 of the terrain. Then, the newly added decal (event texture) is superimposed on the first texture data to obtain the second texture data 703 by drawing. Next, the second texture data 703 is updated to the position corresponding to the target tile 702 on the runtime virtual texture 701 of the terrain, thereby realizing the partial update of the runtime virtual texture 701 of the terrain.

[0073] Thus, through the above-described embodiments, in the case of adding an event texture to the target tile, the new second texture data can be generated based on the first texture data corresponding to the target tile on the virtual texture of the target virtual object, thereby realizing the update of the virtual texture.

[0074] In some implementable embodiments, in step 421, in the case where the texture change type corresponding to the target tile indicates deleting the event texture on the target tile, the first texture data corresponding to the target tile can be obtained from the cache pool. Correspondingly, in step 422, the second texture data corresponding to the target tile can be obtained based on the remaining event textures and the first texture data on the target tile.

[0075] Here, in the case where the texture change type corresponding to the target tile is the second texture change type, since the event texture is deleted on the target tile and the second texture data of the target tile cannot be obtained by drawing based on the first texture data on the virtual texture, the first texture data corresponding to the target tile can be copied from the cache pool. Then, based on the first texture data, in the order of the remaining event textures on the target tile, the remaining event textures are superimposed and drawn on the first texture data to obtain the second texture data corresponding to the target tile.

[0076] It should be understood that since the cache pool is used to cache the texture data of the virtual texture of the target virtual object that does not contain event textures, the first texture data copied from the cache pool does not contain the data of the event texture.

[0077] Figure 8 is a schematic diagram of updating a virtual texture shown according to another exemplary embodiment. As Figure 8 shown, taking the event texture as a decal as an example, the first texture data corresponding to the target tile 802 can be copied from the cache pool corresponding to the terrain. Then, the remaining decals (event textures) of the target tile 802 are superimposed on the first texture data to obtain the second texture data 803 by drawing. Next, the second texture data 803 is updated to the position corresponding to the target tile 802 on the runtime virtual texture 801 of the terrain, thereby realizing the partial update of the runtime virtual texture 801 of the terrain.

[0078] In some embodiments, in the case where the cache pool does not cache the first texture data corresponding to the target tile, the texture materials of the target virtual object corresponding to the target tile are mixed to obtain the third texture data corresponding to the target tile, and the remaining decals of the target tile are overlaid on the third texture data to obtain the second texture data corresponding to the target tile.

[0079] Among them, when the cache pool does not cache the first texture data corresponding to the target tile, the texture data of the target tile cannot be found in the cache pool. At this time, it is necessary to regenerate the texture data of the target tile.

[0080] Such as Figure 8 As shown, in the case where the cache pool does not find the first texture data of the target tile 805, the terrain material of the target tile 805 is mixed to obtain the third texture data of the target tile 805. It should be noted that the third texture data is essentially the same as the first texture data copied from the cache pool. Then, the remaining decals of the target tile 805 are overlaid on the third texture data to obtain the second texture data 804 corresponding to the target tile 805. Then, the second texture data 804 is updated to the position corresponding to the target tile 805 on the runtime virtual texture 801 of the terrain, thereby realizing the partial update of the runtime virtual texture 801 of the terrain.

[0081] It is worth noting that it is generally difficult to trigger the situation where the cache pool does not cache the first texture data corresponding to the target tile during runtime. Because during actual rendering, all Tiles in the current view will be on the virtual texture, and the texture data of all Tiles will be updated to the cache pool for caching. During actual operation, the larger the cache pool, the higher the hit rate of the cache pool. The size of the cache pool can be set according to the actual memory situation.

[0082] Thus, through the above embodiments, in the case of deleting the event texture on the target tile, new second texture data can be generated based on the first texture data corresponding to the target tile in the cache pool, thereby realizing the update of the virtual texture. Even if the cache pool does not cache the first texture data corresponding to the target tile, since only the third texture data of the target tile needs to be regenerated, the performance consumption is not large.

[0083] In some implementable embodiments, in step 410, in response to an event for triggering an event texture change of a target virtual object in the virtual scene, according to the oriented bounding box corresponding to the changed event texture and the quadtree corresponding to the target virtual object, the target tile where the target virtual object has an event texture change is determined.

[0084] Here, an Oriented Bounding Box (OBB) is a cuboid that can be arbitrarily rotated according to the first moment of an object and is used to approximate the object more precisely. The OBB is essentially a cuboid, but different from the traditional Axis-Aligned Bounding Box (AABB), the faces of the OBB do not have to be parallel to any of the three coordinate planes and can be rotated according to the actual shape and orientation of the object, making the OBB more precise when approximating the object and significantly reducing the number of enclosing volumes.

[0085] Among them, each node of the quadtree includes a tile of the target virtual object. Taking the terrain of the target virtual object as an example, the quadtree is used to divide the terrain space, and the Tiles in the terrain are inserted into the quadtree, and each Tile will be assigned to a node of the quadtree.

[0086] The spatial range of the OBB bounding box can be used as a query condition to perform a spatial query in the quadtree to find all the nodes that intersect the OBB bounding box. For each intersecting node, check whether the Tile of the terrain contained in the node intersects the OBB bounding box. If it intersects, the Tile is covered by the event texture, and then the Tile is the target tile.

[0087] Figure 9 is a schematic diagram showing the determination of the target tile according to an exemplary embodiment. As Figure 9 shown, the target tile 902 where the terrain has an event texture change can be obtained through the oriented bounding box 901 corresponding to the event texture with changes and the quadtree of the terrain.

[0088] Thus, through the oriented bounding box and the quadtree, the target tile where the event texture of the target virtual object changes can be accurately determined.

[0089] In some implementable embodiments, in step 420, the tile update rate for updating the virtual texture of the target virtual object can be determined according to the data volume of the target tile, and then based on the event texture after the target tile changes, the texture data corresponding to the tile update rate in the virtual texture of the target virtual object is updated to obtain the updated virtual texture.

[0090] Here, the data volume of the target tile refers to the number of target tiles. For example, if a special effect covers all the terrain within the screen range, then all the Tiles of the terrain displayed on the screen are target tiles that need to be refreshed, and the data volume of the target tiles is all the Tiles of the terrain displayed on the screen. The tile update rate is the number of target tiles that can be updated in one frame of the screen. For example, the tile update rate can be 100 target tiles updated in one frame.

[0091] Among them, the data volume is directly proportional to the tile update rate. That is to say, the larger the data volume of the target tile, the greater the tile update rate. Correspondingly, the larger the number of target tiles that can be updated in a frame of the picture.

[0092] After determining the tile update rate, based on the event texture of the target tile after the change, the texture data of the corresponding number of target tiles in the virtual texture of the target virtual object corresponding to the tile update rate can be updated.

[0093] It should be noted that when the tile update rate for updating the target tiles in each frame of the picture is fixed, the tiles covered by the event texture will change from blurred to clear during the virtual texture update. In the embodiments of the present disclosure, the number of target tiles that can be updated in each frame can be dynamically adjusted according to the data volume of the target tiles, so as to avoid the change process from blurred to clear. Thus, by dynamically adjusting the tile update rate, the change process from blurred to clear can be avoided in the picture, greatly improving the game experience of players.

[0094] In some implementable embodiments, in step 420, during the update of the special effect resources corresponding to the event, based on the event texture of the target tile after the change, the texture data corresponding to the target tile in the virtual texture of the target virtual object can be updated to obtain the updated virtual texture.

[0095] Here, following the above embodiments, the change of the event texture of the target virtual object is triggered by an event, and this event can be a special effect event. For example, when a virtual bomb explodes on the ground, a texture mark such as a crater will be left. At this time, special effect resources and post-processing of the event will appear in the foreground. For example, special effects such as smoke, fire, and distortion caused by the virtual bomb will appear.

[0096] Correspondingly, during the update of the special effect resources corresponding to the event, the texture data corresponding to the target tile in the virtual texture of the target virtual object can be updated to block the update process of the target tile through the special effect resources corresponding to the event, so as to minimize the visually perceived change process of the terrain update.

[0097] Figure 10 It is a schematic diagram of updating a virtual texture shown according to an exemplary embodiment. As Figure 10 shown, after the explosion event occurs, during the process of displaying the explosion special effect corresponding to the explosion event, local updates are performed on the target tiles in the RVT of the terrain. When the explosion special effect is displayed, the RVT of the terrain is updated. Then, in the vision of the player, the change process of the terrain from blurred to clear will not be seen.

[0098] Thus, by updating the virtual texture during the update of the special effect resources corresponding to the event, the update process of the target tile can be blocked by the special effect resources corresponding to the event, thereby minimizing the visually perceived change process of the terrain update.
