[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] In some games, there are terrain areas that need to be updated in real time, and the rendering on this terrain area is an important visual and functional element. For example, in a strategy game (Simulation Game, SLG), in a surface scene containing a farmland area, the following effects need to be achieved: in the long view (when the virtual camera is far away), the material of the target terrain area can be updated in real time according to the growth status of the crops in the current target terrain area (such as seedlings, maturity, harvest, etc.).

[0028] Runtime Virtual Texture (RVT) is a texture technology in game engines that allows complex materials and details to be rendered into virtual textures at runtime, thereby improving performance and detail. However, in related technologies, RVT cannot be updated in real time, and cannot directly show the target terrain area in the distance and the area rendering effect of real-time update changes as the crop growth status changes.

[0029] Based on this, the embodiments of the present invention provide a rendering display method, a rendering display device, an electronic device and a storage medium, which use RVT technology to render the target terrain area in the long view to improve performance, and based on RVT, realize the rendering performance of the target terrain area that is updated in real time as the crop growth status changes.

[0030] In one embodiment of the present invention, the rendering display method can be run on a local terminal device (touch or non-touch client device) or a server. When the rendering display method is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

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

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

[0033] In a possible implementation, an embodiment of the present invention provides a rendering display method, which provides a graphical user interface through a terminal device, wherein the terminal device can be the local terminal device mentioned above, or can be a client device in the cloud interaction system mentioned above. A graphical user interface is provided through the terminal device, and the graphical user interface can display interface content, such as game scene screens, communication interaction windows, game map data, etc., according to the type of application started.

[0034] To facilitate understanding of this embodiment, a rendering display method disclosed in an embodiment of the present invention is first described in detail. Figure 1This is a flow chart of a rendering and display method provided by an embodiment of the present invention. In this embodiment, the rendering and display method includes steps S110 to S120.

[0035] In step S110, the region information of the target terrain region on the virtual surface is recorded in the Mask channel of the runtime virtual texture RVT, the region information includes crop type information, and different crop type information corresponds to different combinations of crop types and crop growth states.

[0036] In some embodiments, the target terrain area may be a farmland area, and in other embodiments, the target terrain area may be a grassland area, a hillside area, or other terrain areas.

[0037] In this embodiment, the crop growth status includes, for example, seedling, mature, harvest and other growth states.

[0038] In some embodiments, the region information also includes a rotation value. The above step of recording the region information of the target terrain region on the virtual surface in the Mask channel of the runtime virtual texture RVT includes: recording the crop type information and the rotation value of the region information in different percentiles of the Mask channel of the RVT. In one example, the crop type information of the region information is recorded in the percentile of the Mask channel of the RVT, and the rotation value is recorded in the thousandth of the Mask channel of the RVT.

[0039] In step S120, during the rendering stage, regional information is obtained from the Mask channel. If the distance between the target terrain area corresponding to the regional information and the virtual camera is greater than or equal to a preset distance threshold, a first map corresponding to the crop type and crop growth status is obtained based on the crop type information, and a crop effect is generated in the target terrain area based on the first map.

[0040] In some embodiments, the region information further includes a region definition value. The region definition value is used to define a target terrain region on the virtual surface. In one example, a definition threshold is preset so that grids with region definition values ​​greater than or equal to the definition threshold are located in the target terrain region.

[0041] In some embodiments, after the step of acquiring area information from the Mask channel, the rendering and display method further includes: determining the target terrain area on the virtual surface based on a comparison result of the area definition value of the sampling grid and a preset definition threshold.

[0042] In one example, the definition threshold is 0.9. At this time, based on the comparison result of the area definition value of the sampling grid and the preset definition threshold, the step of determining the target terrain area on the virtual surface is: if the area definition value of the sampling grid (for example, the area definition value recorded in the "maskRVT" column) is greater than 0.9, then the sampling grid belongs to the target terrain area.

[0043] When the distance between the target terrain area corresponding to the area information and the virtual camera is greater than or equal to the distance threshold, it is equivalent to the distant view state and switches to the distant view rendering mode.

[0044] Figure 2 A flowchart of the steps of obtaining a first map corresponding to a crop type and a crop growth state based on crop type information, and generating a crop effect in a target terrain area based on the first map in a rendering display method provided in an embodiment of the present invention. In some embodiments, the steps of obtaining a first map corresponding to a crop type and a crop growth state based on crop type information, and generating a crop effect in a target terrain area based on the first map include steps S121 to S123.

[0045] In step S121, based on the crop type information, a first numerical value corresponding to the crop type information is output.

[0046] The first value is the crop state value, which is used to correspond to different growth states of the crop. In some embodiments, a plurality of first values, namely, a plurality of crop state values, are defined by a material parameter set, and a corresponding first value, namely, a crop state value, is selected for output according to crop type information.

[0047] In step S122, based on the first numerical value, a map corresponding to the first numerical number is selected from the texture array to obtain a first map corresponding to the crop type and the crop growth status.

[0048] In some embodiments, the first value is used as the Z coordinate of the texture array sample to select a map corresponding to the first value number from the texture array.

[0049] In step S123 , a crop effect is generated in the target terrain area based on the first map.

[0050] In some embodiments, the region information further includes a rotation value. In some embodiments, the step of generating a crop effect in the target terrain region based on the first texture includes: setting UV coordinates of the first texture based on the rotation value, and generating a crop effect in the target terrain region based on the first texture.

[0051] In some embodiments, the rendering and display method further includes: if the distance between the target terrain area corresponding to the region information and the virtual camera is less than a preset distance threshold, generating a crop model corresponding to the crop type information on the target terrain area. That is, when the distance between the target terrain area corresponding to the region information and the virtual camera is less than the preset distance threshold, it is equivalent to a close-up state, and the close-up rendering mode is switched.

[0052] In some embodiments, if the distance between the target terrain area corresponding to the area information and the virtual camera is less than a preset distance threshold, the target terrain area is further configured with a second map, and the second map includes a surface soil effect. That is, in the close-up rendering mode, a crop model corresponding to the crop type information is generated on the target terrain area, and the target terrain area is configured with a second map, and the second map includes a surface soil effect.

[0053] In some embodiments, the step of generating a crop effect in the target terrain area based on the first texture includes: blending the first texture with the second texture in the target terrain area. That is, in the distant view, blending the first texture including the surface crop effect with the second texture including the surface soil effect in the target terrain area.

[0054] In some embodiments, the step of generating a crop effect in the target terrain area based on the first texture further includes: determining a mixing ratio of the first texture and the second texture based on the distance between the target terrain area corresponding to the area information and the virtual camera. Therefore, in the distant view, as the distance between the target terrain area corresponding to the area information and the virtual camera changes, the mixing ratio of the first texture and the second texture in the target terrain area changes accordingly, so as to achieve a smoother transition of the rendering effect of the target terrain area when the viewing angle is zoomed.

[0055] According to the rendering and display method of the embodiment of the present invention, the regional information of the target terrain area on the virtual surface is recorded in the Mask channel of the virtual texture RVT at runtime. In the embodiment of the present invention, the regional information includes crop type information. Different crop type information corresponds to different combinations of crop types and crop growth states. Therefore, different crop type information can match the maps showing different crops in different growth states. In the rendering stage, the regional information is obtained from the Mask channel, and the rendering mode of the target terrain area is switched based on the distance between the target terrain area and the virtual camera. If the distance between the target terrain area corresponding to the regional information and the virtual camera is greater than or equal to the distance threshold, it is a distant view at this time. Based on the crop type information, a first map corresponding to the crop type and the crop growth state is obtained, and a crop effect is generated in the target terrain area based on the first map. At this time, the rendering effect in the target terrain area is expressed as the crop model is removed from the target terrain area, and the surface material of the target terrain area has a specific surface crop texture effect. Moreover, since the first map corresponds to the crop type information, the rendering effect of the target terrain area in the distant view can also be updated with the crop type information. In the above rendering scheme, the performance of the target terrain area in the distance can be improved through RVT technology, and based on RVT, the rendering performance of the target terrain area can be updated in real time as the growth status of the crop changes.

[0056] In some embodiments of the present invention, during the rendering stage, the region information is obtained from the Mask channel, and the rendering mode of the target terrain region is switched based on the distance between the target terrain region corresponding to the region information and the virtual camera. If the distance between the target terrain region and the virtual camera is less than the preset distance threshold, it is a close view, so it is switched to the close view rendering mode. In the close view rendering mode, a crop model corresponding to the crop type information is generated on the target terrain region. At this time, the rendering effect of the target terrain region is manifested as a crop model of a farmland normally displayed on the surface of the target terrain region. Optionally, in the close view rendering mode, a second map is also configured in the target terrain region, wherein the second map includes a surface soil effect. At this time, the rendering effect of the target terrain region is manifested as the surface of the target terrain region being a soil surface material, and the crop model of a farmland is normally displayed on the surface of the target terrain region. If the distance between the target terrain area and the virtual camera is greater than or equal to the distance threshold, it is a distant view, so it is switched to distant view rendering mode. In the distant view rendering mode, based on the crop type information, a first map corresponding to the crop type and the crop growth state is obtained, and a crop effect is generated in the target terrain area based on the first map, wherein the first map includes a surface crop effect. At this time, the rendering effect in the target terrain area is manifested as the crop model is removed from the target terrain area, and the surface material of the target terrain area has a specific surface crop texture effect. Moreover, since the first map corresponds to the crop type information, the rendering effect of the target terrain area in the distant view can also be updated with the crop type information.

[0057] According to the rendering and display method of an embodiment of the present invention, large-scale crop texture data is dynamically managed at runtime through RVT technology, which significantly reduces video memory usage and rendering overhead. In some embodiments, through vertex animation and physical simulation technology, the crops in the target terrain area appear more naturally in dynamic environments such as wind and rain, thereby enhancing the immersion of the game. In some embodiments, through dynamic materials and blending technologies such as pixel jitter, the material transition of crops in the target terrain area during the growth stage is ensured to be natural, avoiding harsh visual effects. In some embodiments, the rendering and display method of an embodiment of the present invention can combine level of detail (LOD) and asynchronous loading technology to maintain high frame rates in large-scale scenes and provide a smooth gaming experience.

[0058] The embodiment of the present invention also provides a rendering display device. Figure 3 The structural block diagram of a rendering display device provided by an embodiment of the present invention is as follows. The rendering display device comprises an information recording module 110 and a first rendering module 120 .

[0059] The information recording module 110 is used to record the regional information of the target terrain area on the virtual surface in the Mask channel of the virtual texture RVT at runtime. The regional information includes crop type information. Different crop type information corresponds to different combinations of crop types and crop growth states.

[0060] The first rendering module 120 is used to obtain area information from the Mask channel, and when the distance between the target terrain area corresponding to the area information and the virtual camera is greater than or equal to a preset distance threshold, obtain a first map corresponding to the crop type and crop growth status based on the crop type information, and generate a crop effect in the target terrain area based on the first map.

In the embodiment of the present invention, the regional information includes crop type information. Different crop type information corresponds to different combinations of crop types and crop growth states. Therefore, different crop type information can match maps showing different crops in different growth states. In the rendering stage, the first rendering module 120 is used to obtain the regional information from the Mask channel, and when the distance between the target terrain area corresponding to the regional information and the virtual camera is greater than or equal to a preset distance threshold, based on the crop type information, obtain the first map corresponding to the crop type and the crop growth state, and generate a crop effect in the target terrain area based on the first map. At this time, the rendering effect in the target terrain area is manifested as the crop model is removed from the target terrain area, and the surface material of the target terrain area has a specific surface crop texture effect. Moreover, since the first map corresponds to the crop type information, the rendering effect of the target terrain area in the distant view can also be updated with the crop type information. In the above rendering scheme, the performance of the target terrain area in the distance can be improved through RVT technology, and based on RVT, the rendering performance of the target terrain area can be updated in real time as the growth status of the crop changes.

[0062] In some embodiments, the region information further includes a rotation value, and the information recording module 110 is configured to record the crop type information and the rotation value of the region information in different quantiles of the Mask channel of the RVT.

[0084] According to an embodiment of the present invention, the electronic device includes a processor 901 and a memory 902. When the processor 901 executes machine executable instructions to implement the above rendering display method, the region information of the target terrain area on the virtual surface is recorded in the Mask channel of the virtual texture RVT at runtime. In the embodiment of the present invention, the region information includes crop type information.
