[0002] In a network game of a simulation management survival type in a snow scene, thermal energy is an important survival resource. Taking a game scene of a town as an example, a player needs to continuously improve the heating of each building in the city to resist the continuous decrease of the environmental temperature, and if the heating of a certain building is insufficient, the temperature will be low, thereby affecting the normal operation of the building. In order to facilitate the player to view the thermal energy distribution of each building in the city in real time, it is necessary to provide a display mode of a direct thermal energy rendering effect.

[0003] In some related technical solutions, the thermal energy data in the game scene is saved into a 3-channel map, and the rendering effect of the current building in the thermal energy display mode is obtained from the 3-channel map according to the position of the building in the world space.

[0004] However, the above technical solution causes large rendering performance overhead, thereby affecting the smoothness in the game running process.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] The present disclosure provides a thermal energy effect rendering method, a thermal energy effect rendering device, a computer storage medium and an electronic device, which can reduce the performance overhead of game picture rendering, thereby improving the smoothness of game running.

[0007] In a first aspect, an embodiment of the present disclosure provides a thermal energy effect rendering method, comprising: determining a first position of a virtual model to be rendered in a current game scene; finding first thermal energy data corresponding to the first position from a pre-constructed rendering texture map; wherein the rendering texture map comprises different positions in the current game scene and thermal energy data corresponding to each position; finding a target color value corresponding to the first thermal energy data from a pre-constructed color lookup table; wherein the color lookup table comprises different thermal energy data and color values corresponding to each thermal energy data; and rendering a thermal energy effect in the target virtual model based on the target color value, to obtain a target virtual model corresponding to the virtual model to be rendered.

[0008] In a second aspect, an embodiment of the present disclosure provides a thermal effect rendering device, the device comprising: a position determining module configured to determine a first position of a virtual model to be rendered in a current game scene; a data searching module configured to search for first thermal data corresponding to the first position from a pre-constructed rendering texture map; wherein the rendering texture map comprises different positions in the current game scene and thermal data corresponding to each position; a color searching module configured to search for a target color value corresponding to the first thermal data from a pre-constructed color lookup table; wherein the color lookup table comprises different thermal data and color values corresponding to each thermal data; and a thermal rendering module configured to render a thermal effect in the target virtual model based on the target color value to obtain a target virtual model corresponding to the virtual model to be rendered.

[0009] In a third aspect, an embodiment of the present disclosure provides a computer readable storage medium having a computer program stored thereon, the computer program being executed by a processor to implement the thermal effect rendering method as described above.

[0010] In a fourth aspect, an embodiment of the present disclosure provides an electronic device, comprising: a processor; and a memory configured to store executable instructions of the processor; wherein the processor is configured to execute the thermal effect rendering method as described above via execution of the executable instructions.

[0011] The technical solution of the present disclosure has the following beneficial effects:

[0012] The heat energy effect rendering method determines a first position of a virtual model to be rendered in a current game scene, finds first heat energy data corresponding to the first position from a pre-constructed rendering texture map, finds a target color value corresponding to the first heat energy data from a pre-constructed color lookup table, and renders a heat energy effect in the target virtual model based on the target color value to obtain a target virtual model corresponding to the virtual model to be rendered. On the one hand, the rendering texture map only stores heat energy data of virtual models in the current game scene, forming a single-channel rendering texture map, and the color lookup table is also a one-dimensional data table, which occupies less data storage space, thereby solving the technical problem that the performance overhead of game picture rendering is large due to the use of a three-channel color map in the prior art, which further affects the fluency of game running, and achieving the technical effect of reducing the performance overhead of game picture rendering and further improving the fluency of game running. On the other hand, the method is not limited by specific programs, and can avoid storing data in a three-channel color map by using specific operation programs that need to be executed on a graphics processing unit (GPU), such as Compute shader technology. However, devices that can carry Compute shader are very limited, which affects the popularity of heat energy rendering effect display, thereby realizing the improvement of the coverage of heat energy rendering effect display.

[0024] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings.

In addition, to avoid "double negatives" in the claims, the terms "neither / nor" and "none" are used in the claims to indicate that the term does not include the possibility of the presence of the feature or features.

[0025] In addition, the drawings are only schematic and are non-limiting. Like reference numerals designate corresponding parts throughout the several views. Some embodiments will be described using the expression "coupled" and "connected" along with their derivatives, which are intended to mean either an indirect or direct connection. Thus, any connection made between components in the description can be "coupled" or "connected" whether or not it is made directly or indirectly through one or more intervening components also "coupled" or "connected." Further, the term "coupled" is intended to also encompass a relationship in which one or more intervening components are present.

[0026] The flow diagrams depicted in the figures are merely exemplary and do not necessarily include all of the steps that can be implemented by the embodiments. For example, one or more steps can be combined or omitted, and the order of the steps can be changed about from the examples shown. Further, the steps need not be performed in the order shown, but can be performed in any order, or in parallel.

[0027] In order to help the skilled in the art better understand the technical solutions of the present disclosure, the related content involved in the technical solutions of the present disclosure will be introduced below.

[0028] (1) Render Texture: record data objects in the form of images, which are often used to save intermediate results in the rendering process.

[0029] (2) Compute Shader technology: a computing program executed on a GPU, based on Compute Shader, programmers can directly use the GPU as a parallel processor, and the GPU will not only have 3D rendering capability, but also have other computing capabilities. Compute Shader is often used to assist the Central Processing Unit (CPU) in computing.

[0030] (3) Lookup table (LUT): a set of data correspondence is stored in the form of an image. A set of parameters (usually two-dimensional coordinates of the image) can be used as a lookup entry to read a set of related data (usually color values on the corresponding two-dimensional coordinates of the image).

[0031] The thermal energy effect rendering method provided by the exemplary embodiments of the present disclosure can be applied to application scenarios that need to display thermal energy rendering effects. For example, for a network game of the simulation management survival type in a snow environment, thermal energy is an important survival resource closely related to the core gameplay of the game. Players need to continuously heat the entire city to resist the continuous decline of the environmental temperature, so as to maintain the normal activities of virtual characters in the city. If the heating of a building is insufficient, resulting in a low temperature, the building will not be able to operate normally. Therefore, in order to facilitate players to quickly view the thermal energy distribution of each building in the city, it is necessary to provide a display method of thermal energy rendering effects.

[0032] In order to realize the display method of thermal energy rendering effects, in some technical solutions, compute shader is used to perform parallel calculation on the thermal energy data of the current game scene, and the thermal energy data is saved into a global 3-channel color RenderTexture. During rendering, the color of the RenderTexture is sampled according to the coordinate position of the current rendering building in the world space, so that the color of the current building in the thermal display mode can be obtained.

[0033] However, the above method of using compute shader to store the heat data of the whole game scene in combination with a 3-channel color Render Texture has the following problems. On the one hand, the 3-channel color Render Texture occupies a large storage space, and thus the Render Texture occupies the memory resources of the device running the game during the game running process, resulting in a large heat rendering performance consumption and affecting the fluency of the game running, and further affecting the game experience of the players. On the other hand, since there are limited mobile devices supporting the compute shader function, only some high-end models support it, and currently this technology is mostly applied to the scene of playing games on a Personal Computer (PC) client. Therefore, the above method is limited by the game device, resulting in a low popularization rate or coverage.

[0034] The exemplary embodiments of the present disclosure consider the above problems and propose a heat effect rendering method, which saves the heat data to a single-channel render texture map. The format of the render texture map is 1024 R8_UNorm. Since the R8_UNorm type is only 8 bits, the performance overhead is very small, and the color lookup table (LUT map) is also a one-dimensional picture, the size of the LUT map is 4 512 pixels, and the data storage space occupied is extremely low, so that the global heat display effect can be realized. Therefore, the method can ensure the picture quality of the heat rendering effect display, and the small memory occupation can improve the game performance. At the same time, the hardware function used by the method can support the use of most mobile devices, so that most of the mobile devices of the user group of the game can run the heat rendering effect of the game, and the coverage of the heat rendering effect display is improved.

[0035] Figure 1 The system architecture diagram of the heat effect rendering method provided by the exemplary embodiments of the present disclosure is schematically shown as Figure 1 shown, the heat rendering system 100 includes one or more of terminal devices 101, 102, 103, and 104, a network 105, and a server 106. The network 105 is used to provide a communication link medium between the terminal devices 101, 102, 103, and 104 and the server 106. The network 105 can include various connection types, such as wired, wireless communication links, or optical fiber cables, etc. The terminal devices 101, 102, 103, and 104 can be smart phones, tablet computers, notebook computers, desktop computers, etc., but are not limited thereto.

[0036] It should be understood that Figure 1The number of terminal devices, networks, and servers in the figure is only illustrative. According to the implementation needs, there can be any number of terminal devices, networks, and servers. For example, the server 106 can be a stand-alone physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, and basic cloud computing services such as big data and artificial intelligence platforms.

[0037] The thermal energy effect rendering method provided by the embodiments of the present disclosure can be executed in the server 106. Accordingly, the game interaction device is generally arranged in the server 106. The thermal energy effect rendering method provided by the embodiments of the present disclosure can also be executed in the terminal device. Accordingly, the thermal energy effect rendering device can also be arranged in the terminal device. The thermal energy effect rendering method provided by the embodiments of the present disclosure can also be partially executed in the server 106 and partially executed in the terminal. Accordingly, part of the modules of the thermal energy effect rendering device can be arranged in the server 106, and part of the modules can be arranged in the terminal device.

[0038] For example, in an exemplary embodiment, a user can play a game through the terminal device 101, 102, 103, or 104. The server 106 can start a game process to make the terminal devices 101, 102, 103, and 104 enter the same game. If the player plays the game through the terminal device 101, the terminal device 101 determines a first position of a virtual model to be rendered in a current game scene, and finds first thermal energy data corresponding to the first position from a pre-constructed rendering texture map; wherein the rendering texture map contains different positions in the current game scene and thermal energy data corresponding to each position; the terminal device 101 finds a target color value corresponding to the first thermal energy data from a pre-constructed color lookup table; wherein the color lookup table contains different thermal energy data and color values corresponding to each thermal energy data; and renders the thermal energy effect in the target virtual model based on the target color value to obtain a target virtual model corresponding to the virtual model to be rendered.

[0039] However, those skilled in the art can easily understand that the above application scenarios are only for example, and the present exemplary embodiment is not limited thereto.

[0040] The following takes the terminal device as the execution subject and takes any one of the above terminal devices as an example to illustrate the thermal energy effect rendering method. Referring to Figure 2 The thermal energy effect rendering method provided by the embodiments of the present disclosure can include the following steps S201-S204:

[0041] Step S201, determining a first position of a virtual model to be rendered in a current game scene.

[0042] Step S202, find the first thermal energy data corresponding to the first position from the pre-constructed rendering texture map; wherein the rendering texture map contains different positions in the current game scene and the thermal energy data corresponding to each position.

[0043] Step S203, find the target color value corresponding to the first thermal energy data from the pre-constructed color lookup table; wherein the color lookup table contains different thermal energy data and the color value corresponding to each thermal energy data.

[0044] Step S204, render the thermal energy effect in the target virtual model based on the target color value to obtain the target virtual model corresponding to the virtual model to be rendered.

[0045] In the technical scheme provided by some embodiments of the present disclosure, by determining the first position of the virtual model to be rendered in the current game scene, finding the first thermal energy data corresponding to the first position from the pre-constructed rendering texture map, finding the target color value corresponding to the first thermal energy data from the pre-constructed color lookup table, and rendering the thermal energy effect in the target virtual model based on the target color value, the target virtual model corresponding to the virtual model to be rendered is obtained. On the one hand, the method only stores the thermal energy data of each virtual model in the current game scene in the rendering texture map, forming a single-channel rendering texture map, and the color lookup table is also a one-dimensional data table, occupying less data storage space, thereby solving the technical problem that the large performance overhead of game picture rendering caused by the three-channel color map used in the prior art affects the smoothness of game running, and achieving the technical effect of reducing the performance overhead of game picture rendering and improving the smoothness of game running. On the other hand, the method is not limited by specific programs, and can avoid the need to use specific operation programs executed on the GPU to store data into a three-channel color map, such as the Compute shader tool. However, devices that can carry Compute shader are very limited, which affects the popularity of thermal energy rendering effect display, thereby improving the coverage rate of thermal energy rendering effect display.

[0046] In the following, each step of the thermal energy effect rendering method in the exemplary embodiments of the present disclosure will be further described in detail.

[0047] In step S201, the first position of the virtual model to be rendered in the current game scene is determined.

[0048] In an optional embodiment of the present disclosure, the current game scene can be a game scene captured and displayed in the game view by the current virtual camera, and the virtual models to be rendered are all virtual models viewable within the view range of the current game scene; or the current game scene can be the entire current game scene, and the virtual models to be rendered are all virtual models in the game scene.

[0049] It should be understood that the virtual models to be rendered can be related to the direction of the virtual camera, and the player can adjust the direction of the virtual camera in real time through the control operation of the auxiliary control, so as to view the thermal rendering effect of each virtual model and improve the game experience of the player.

[0050] In order to facilitate understanding of the virtual models to be rendered in the current game scene, the following Figure 3 , Figure 4 will be described in detail.

[0051] Figure 3 , Figure 4 are display schematic diagrams of different game views containing the same virtual models under the same game scene. Among them, Figure 3 schematically shows the virtual model to be rendered under the first view angle in the present exemplary embodiment.

[0052] As shown in Figure 3 , in the first view angle, the current game scene contains virtual model A, virtual model B, virtual model C and virtual model D, wherein virtual model C and virtual model D are respectively blocked by virtual model A and virtual model B. In order to reduce the rendering performance consumption and system calculation amount, only virtual model A and virtual model B within the view range can be taken as the virtual models to be rendered.

[0053] Figure 4 schematically shows the virtual model to be rendered under the second view angle in the present exemplary embodiment. As shown in Figure 4 , the second view angle is a top view angle of the game scene, and all virtual models in the game scene can be viewed under the second view angle, so the virtual models to be rendered are virtual model A, virtual model B, virtual model C and virtual model D.

[0054] It should be noted that, Figure 3 , Figure 4 , the virtual model in the current game scene can also include a two-dimensional virtual model composed of the ground. For example, in the simulation survival type game scene of urban heating, the ground also has temperature data, and when rendering, the ground will also be displayed with the color value corresponding to the thermal energy data of the ground.

[0055] In an optional embodiment of the present disclosure, the virtual model occupies space in the virtual space world, and when determining the first position of the virtual model to be rendered in the current game scene, the virtual model A shown in FIG. 8 is taken as an example, an xyz coordinate system is established with the lower left corner position as the coordinate origin, the current game scene is projected into the xoy plane along the z-axis direction, and the center position (coordinate value (5, 5)) is taken as the first position of the virtual model A in the current game scene. Figure 4

[0056] It should be understood that the coordinate value of the first position is related to the selected coordinate system. However, the first position of the virtual model to be rendered in the current game scene, that is, the relative position of the virtual model in the game scene is not affected by the collection direction of the virtual camera, and is only the coordinate form under different directions, wherein the coordinate values of different coordinate forms can be converted to each other.

[0057] In some example embodiments of the present disclosure, before determining the first position of the virtual model to be rendered in the current game scene, the current game scene can be switched to the rendering mode in response to a rendering confirmation operation for the current game scene.

[0058] Exemplarily, the target virtual model obtained by rendering the heat energy effect in the virtual model to be rendered is a special display effect in the game. In the process of playing the game by the player, the first state is usually displayed. When the player needs to view the distribution of heat energy in the current game scene, the first state needs to be switched to the rendering mode, so as to display in the second state. Wherein, the first state is the actual display state of the virtual model, that is, the display state of the building similar to the actual environment, and the second state is the heat energy display effect corresponding to the target virtual model.

[0059] Exemplarily, when the current game scene is switched to the rendering mode, the player can trigger the heat energy effect control on the graphical user interface, and the terminal device switches the current game scene to the rendering mode in response to a rendering confirmation operation for the current game scene.

[0060] By responding to the rendering confirmation operation for the current game scene to switch the current game scene to the rendering mode, the rendering mode can be switched when the player actively triggers, so as to reduce the rendering performance consumption while improving the human-computer interaction experience of the player.

[0061] In another optional embodiment of the present disclosure, the terminal device can collect game data at the current time, and automatically switch the current game scene to the rendering mode according to the game data.

[0062] ​The game data is related to a currently running game. Taking a current game scene as an example, the game data can be the positions of the buildings and the thermal energy data, etc.

[0063] Exemplarily, the current game scene can be automatically switched to the rendering mode when the game data meets a preset condition. For example, the temperature value of the virtual model to be rendered in the current game scene is lower than a certain temperature threshold, and the number of the virtual models to be rendered whose temperature value is lower than the certain temperature threshold is greater than a preset number, the current game scene is automatically switched to the rendering mode, so as to timely supplement the thermal energy for the player, thereby assisting the player in playing the game and improving the game experience of the player.

[0064] In step S202, the first thermal energy data corresponding to the first position is found from the pre-constructed rendering texture map. The rendering texture map contains different positions in the current game scene and the thermal energy data corresponding to each position.

[0065] According to some embodiments of the present disclosure, the UV coordinate in the rendering texture map is determined according to the first position of the virtual model to be rendered in the virtual space, so as to determine the thermal energy data corresponding to the UV coordinate as the first thermal energy data corresponding to the first position. The specific program logic is as follows:

[0066] float2 heatUV = posWS.xz heatMapUVST.xy + heatMapUVST.zw;

[0067] float heatValue = tex2D(_HeatMapTexture, heatUV).x;

[0068] Further, before finding the first thermal energy data corresponding to the first position from the pre-constructed rendering texture map, the rendering texture map for the current game scene needs to be constructed.

[0069] Figure 5 An exemplary flowchart for constructing the rendering texture map for the current game scene in the present exemplary embodiment is schematically shown. Referring to FIG. 5, Figure 5 In an optional embodiment of the present disclosure, the above-mentioned step of constructing the rendering texture map for the current game scene can include the following steps S501-S502:

[0070] In step S501, the thermal energy data of each virtual model in the current game scene is determined.

[0071] In an example embodiment of the present disclosure, target temperature data of each virtual model in the current game scene is determined, a target heat energy interval corresponding to the target temperature data is determined in a pre-set heat energy interval, and heat energy data corresponding to the target heat energy interval is determined as target heat energy data corresponding to the target temperature data.

[0072] For example, the continuous temperature data can be divided into 10 heat energy intervals with the same interval in the temperature interval from-80℃ to 20℃.

[0073] The terminal device can collect the target temperature data of each virtual model in the current game scene in real time, determine the corresponding target heat energy interval according to the target temperature data, and determine the heat energy data corresponding to the target heat energy interval as the target heat energy data corresponding to the target temperature data.

[0074] For example, the continuous temperature data in the temperature interval is divided into 10 heat energy intervals, which can be sorted according to the size of the temperature data. The temperature data in each interval is uniformly converted into a heat energy data, respectively, as level 1 to level 10, wherein level 1 represents the heat energy interval with the lowest temperature, and level 10 represents the heat energy interval with the highest temperature. Assuming that the target temperature data of the virtual model is 10℃, and 10℃ is in the 9th heat energy interval, the current target heat energy data is 9.

[0075] The heat energy data corresponding to the target heat energy interval is determined as the target heat energy data corresponding to the target temperature data, which can configure the temperature in one interval as one heat energy data, thereby reducing the calculation amount and reducing the performance consumption in the rendering process.

[0076] In an optional embodiment of the present disclosure, initial temperature data of each virtual model in the current game scene is determined, and the initial temperature data is normalized to obtain target temperature data.

[0077] For example, the temperature in the interval from-80℃ to 20℃ is mapped to the heat energy interval from 0 to 1, and the temperature lower than-80℃ can be configured as 0, and the temperature higher than 20℃ can be configured as 1.

[0078] The terminal device normalizes the collected initial temperature data of each virtual model, and the specific calculation logic is as follows:

[0079] objectIntensity (target heat energy data) = objectHeatLevel (target heat energy interval where the current virtual model is located) / environmentMaxHeatLevel (total number of heat energy intervals of the game).

[0080] For example, if the target thermal energy data is 9 and the total number of thermal energy intervals divided in the game is 10, then the target thermal energy data = 9 / 10 = 0.9.

[0081] Step S502: Construct a rendering texture map based on the thermal data and the position of the corresponding virtual model.

[0082] Building and rendering texture maps based on the current game scene can improve scene matching and the accuracy of thermal rendering effects.

[0083] Figure 6 This schematically illustrates a rendering texture map in this exemplary embodiment, with reference to... Figure 6 , Figure 6 In the image (a), the virtual model to be rendered in the current game scene is shown from a top-down perspective. Figure 6 (b) in the text refers to Figure 6 The location of the virtual model shown in (a) and the rendering texture map constructed from the thermal data of each virtual model.

[0084] Normalizing the temperature data of each virtual model helps to limit the temperature data to a preset thermal energy range, so as to determine the color value corresponding to the thermal energy data in the future, thereby reducing the impact of abnormal data and improving the reliability of system calculation.

[0085] In step S203, the target color value corresponding to the first thermal energy data is obtained from a pre-constructed color lookup table; wherein, the color lookup table contains different thermal energy data and the color value corresponding to each thermal energy data.

[0086] For example, a color lookup table (LUT) contains a one-to-one mapping between thermal data and color values. Therefore, after determining the first thermal data, the LUT image can be sampled based on the first thermal data to obtain the color value of the current virtual model in thermal display mode. The program logic for this process is as follows:

[0087] half3 heatColor = tex2D(_HeatColorLUT, float2(heatValue, 0.5));

[0088] It should be understood that when the thermal energy data is in the range of 0-1, the corresponding color value in the color lookup table is also in the range of 0-1.

[0089] In step S204, the thermal effect in the target virtual model is rendered based on the target color value to obtain the target virtual model corresponding to the virtual model to be rendered.

[0090] In one optional embodiment of this disclosure, the target virtual model is displayed in the current game scene.

[0091] When the thermal energy effect in the target virtual model is rendered based on the target color value, the target virtual model can be displayed on the graphical user interface, i.e., displayed in different color values, so that the player can view the current thermal energy distribution in real time through different color values, thereby better implementing corresponding game strategy operations, and further improving the game experience of the player.

[0092] In some example embodiments of the present disclosure, if the first position of the virtual model is updated to a second position, the rendering texture map is updated based on the second position to obtain an updated first rendering texture map, and / or if the first thermal energy data of the virtual model is updated to second thermal energy data, the rendering texture map is updated based on the second thermal energy data to obtain an updated second rendering texture map.

[0093] For example, after the thermal energy effect in the target virtual model is rendered based on the target color value to obtain the target virtual model corresponding to the virtual model to be rendered, the rendering texture map can be updated in real time.

[0094] According to the update of the virtual model position information, the thermal energy data is updated in real time to obtain the updated second rendering texture map, thereby improving the accuracy of the thermal energy effect rendering.

[0095] For example, since the thermal energy distribution information changes continuously as the game progresses, in order to improve the accuracy of the generated target virtual model after rendering, the rendering texture map needs to be updated before the first thermal energy data corresponding to the first position is found from the pre-constructed rendering texture map.

[0096] At the same time, when updating the rendering texture map, in order to ensure the robust and stable operation of the system, the integrity of the system needs to be checked first, for example, whether the rendering texture map has been constructed, whether the thermal energy data is within the threshold interval set by the system, etc.

[0097] According to some embodiments of the present disclosure, when the thermal energy data of the virtual model changes, the rendering texture map is updated.

[0098] According to some embodiments of the present disclosure, when the position of the virtual model in the current game scene changes, the rendering texture map is updated.

[0114] The thermal energy effect rendering device 800 provided by the embodiments of the present disclosure can execute the technical solutions of the thermal energy effect rendering method in any of the above embodiments, and the implementation principles and beneficial effects thereof are similar to those of the thermal energy effect rendering method. For details, refer to the implementation principles and beneficial effects of the thermal energy effect rendering method, which will not be described here again.

[0115] In the example embodiments of the present disclosure, a computer readable storage medium is also provided, and the computer readable storage medium has a program product stored thereon, which can implement the method described in the present specification. In some possible implementation manners, various aspects of the present disclosure can also be implemented in the form of a program product, which includes program codes for causing a terminal device to execute the steps described in the “example method” section of the present specification according to various example embodiments of the present disclosure when the program product runs on the terminal device.

[0116] determine a first position of the virtual model to be rendered in the current game scene; find first heat data corresponding to the first position from a pre-constructed rendering texture map; wherein the rendering texture map contains different positions in the current game scene and heat data corresponding to each position; find a target color value corresponding to the first heat data from a pre-constructed color lookup table; wherein the color lookup table contains different heat data and color values corresponding to each heat data; and render a heat effect in the target virtual model based on the target color value to obtain a target virtual model corresponding to the virtual model to be rendered.

[0117] On the one hand, the method only stores heat data of each virtual model in the current game scene in the rendering texture map, forming a single-channel rendering texture map, and the color lookup table is also a one-dimensional data table, which occupies less data storage space, thereby solving the technical problem that the large performance overhead of game picture rendering caused by the use of a three-channel color map in the prior art, and further affecting the fluency of game running, and achieving the technical effect of reducing the performance overhead of game picture rendering, and further improving the fluency of game running. On the other hand, the method is not limited by a specific program, and can avoid the need for some technologies to use a specific operation program executed on a graphics processing unit (GPU) to store data in a three-channel color map, such as the Compute shader technology. However, devices that can carry the Compute shader are very limited, thereby affecting the popularity of the heat rendering effect display, and thereby improving the coverage of the heat rendering effect display.

[0118] In some example embodiments of the present disclosure, heat data of each virtual model in the current game scene is determined, and a rendering texture map is constructed according to the heat data and the positions of the corresponding virtual models.

[0119] Constructing the rendering texture map through the current game scene can improve scene matching and improve the accuracy of the heat rendering effect.

[0120] In some example embodiments of the present disclosure, target temperature data of each virtual model in the current game scene is determined, a target heat data interval corresponding to the target temperature data is determined in a pre-set heat data interval, and heat data corresponding to the target heat data interval is determined as the target heat data corresponding to the target temperature data.

[0121] Determining the heat data corresponding to the target heat data interval as the target heat data corresponding to the target temperature data can configure the temperature in one interval as one heat data, thereby reducing the amount of calculation and reducing the performance consumption in the rendering process.

[0122] In some example embodiments of the present disclosure, initial temperature data of each virtual model in the current game scene is determined; and the initial temperature data is normalized to obtain target temperature data.

[0123] The normalization of the temperature data of each virtual model facilitates limiting the temperature data in a preset thermal energy interval, so as to subsequently determine a color value corresponding to the thermal energy data, thereby reducing the influence of abnormal data and improving the reliability of system calculation.

[0124] In some example embodiments of the present disclosure, if the first position of the virtual model is updated to a second position, the rendering texture map is updated based on the second position to obtain an updated first rendering texture map, and / or if the first thermal energy data of the virtual model is updated to second thermal energy data, the rendering texture map is updated based on the second thermal energy data to obtain an updated second rendering texture map.

[0125] According to the update of the virtual model position information, the thermal energy data is updated in real time and the updated second rendering texture map is obtained, thereby improving the accuracy of thermal energy effect rendering.

[0126] In some example embodiments of the present disclosure, before determining the first position of the virtual model to be rendered in the current game scene, the current game scene can be switched to a rendering standby mode according to a rendering confirmation operation for the current game scene.

[0127] By responding to the rendering confirmation operation for the current game scene to switch the current game scene to the rendering standby mode, the rendering standby mode can be switched when triggered by the player, thereby reducing the rendering performance consumption while improving the human-computer interaction experience of the player.

[0128] In an optional embodiment of the present disclosure, the target virtual model is displayed in the current game scene.

[0129] After the thermal energy effect in the target virtual model is rendered based on the target color value, the target virtual model can be displayed on the graphical user interface, i.e., displayed with different color values, so that the player can view the current thermal energy distribution in real time through different color values, thereby better implementing corresponding game strategy operations and further improving the game experience of the player.
