Embodiments of the present application provide a method and an apparatus for adaptive display of a virtual scene, an electronic device, a computer-readable storage medium, and a computer program product, which are capable of smoothly switching and displaying a virtual object based on an accurate level-of-detail model. In order to facilitate easier understanding of the adaptive display method for a virtual scene provided in the embodiments of the present application, an exemplary implementation scenario of the adaptive display method for a virtual scene provided in the embodiments of the present application is first described.

In some embodiments, the virtual scene may be an environment for game characters to interact with, for example, game characters to play against in the virtual scene, and the two-way interaction may be performed in the virtual scene by controlling actions of the game characters, so that the user can relieve life stress during the game.

In an implementation scenario, referring to fig. 1A, fig. 1A is an application mode schematic diagram of an adaptive display method for a virtual scene provided in an embodiment of the present application, and is applicable to application modes that can complete calculation of related data of the virtual scene 100 completely depending on a computing capability of graphics processing hardware of a terminal 400, such as a game in a single-computer/offline mode, and output of the virtual scene is completed through various different types of terminals 400, such as a smart phone, a tablet computer, and a virtual reality/augmented reality device.

As an example, types of Graphics Processing hardware include a Central Processing Unit (CPU) and a Graphics Processing Unit (GPU).

When the visual perception of the virtual scene 100 is formed, the terminal 400 calculates and displays required data through the graphic computing hardware, completes the loading, analysis and rendering of the display data, and outputs a video frame capable of forming the visual perception on the virtual scene at the graphic output hardware, for example, a two-dimensional video frame is displayed on a display screen of a smart phone, or a video frame realizing a three-dimensional display effect is projected on a lens of an augmented reality/virtual reality glasses; in addition, the terminal 400 may also form one or more of auditory perception, tactile perception, motion perception, and taste perception by means of different hardware in order to enrich the perception effect.

As an example, the terminal 400 runs a client 410 (e.g. a standalone version of a game application), and outputs a virtual scene including role play during the running process of the client 410, wherein the virtual scene may be an environment for game role interaction, such as a plain, a street, a valley, and the like for game role battle; taking the example of displaying the virtual scene 100 from a first-person perspective, in the virtual scene 100, the virtual object 101 and the plane 102 are located in the field of view of the camera, the virtual object 101 may be a game character controlled by a user (or a player), that is, the virtual object 101 is controlled by a real user (an enemy), and will operate in the virtual scene in response to the real user's operation of buttons (including a rocker button, an attack button, a defense button, and the like), for example, when the real user moves the rocker button to the left, the virtual object will move to the left in the virtual scene, and may also remain stationary in place, jump, and use various functions (such as skills and props); the virtual object 101 may also be Artificial Intelligence (AI) set in a virtual scene fight by training; the virtual object 101 may also be a Non-user Character (NPC) set in the virtual scene interaction; the virtual object 101 may also be an immovable object or a movable object in the virtual scene 100.

For example, taking the top view angle of the first human-scale view angle to display the virtual scene 100 as an example, the virtual ground and the virtual object 101 in the field of view of the camera are displayed in the virtual scene, and the virtual object controlled by the player in the virtual scene is subjected to dive, that is, the camera is subjected to dive, so that the virtual object 101 and the virtual ground in the field of view of the camera are closer to the camera, and an accurate and adaptive detail level model is determined by combining two parameters, namely a camera position parameter and a graphic processing performance parameter, of the virtual scene 100, so that the virtual object 101 and the virtual ground are smoothly switched based on the accurate and adaptive detail level model, more appropriate details of the virtual object 101 and the virtual ground can be seen, the human-computer interaction effect of the virtual scene is improved, and the use experience of the user is also improved.

In another implementation scenario, referring to fig. 1B, fig. 1B is an application mode schematic diagram of the adaptive display method for a virtual scene provided in this embodiment, which is applied to a terminal 400 and a server 200, and is adapted to complete virtual scene calculation depending on the calculation capability of the server 200 and output an application mode of the virtual scene at the terminal 400.

Taking the visual perception forming the virtual scene 100 as an example, the server 200 performs calculation of display data (e.g., scene data) related to the virtual scene and sends the calculated display data to the terminal 400 through the network 300, the terminal 400 relies on graphics computing hardware to complete loading, parsing and rendering of the calculated display data, and relies on graphics output hardware to output the virtual scene to form the visual perception, for example, a two-dimensional video frame may be presented on a display screen of a smart phone, or a video frame realizing a three-dimensional display effect may be projected on a lens of augmented reality/virtual reality glasses; for perception in the form of a virtual scene, it is understood that an auditory perception may be formed by means of corresponding hardware outputs of the terminal 400, for example using a microphone, a tactile perception using a vibrator, etc.

As an example, the terminal 400 runs a client 410 (e.g., a network-based game application) thereon, and performs game interaction with other users by connecting to the server 200 (e.g., a game server), the terminal 400 outputs the virtual scene 100 of the client 410, displays the virtual scene 100 in a first-person perspective as an example, a virtual object 101 and a plane 102 in the virtual scene 100, which are located in the field of view of the camera, the virtual object 101 may be a game character controlled by a user (or player), i.e., the virtual object 101 is under the control of a real user (adversary), will operate in a virtual scene in response to the real user's operation of buttons (including rocker buttons, attack buttons, defense buttons, etc.), for example, when a real user moves the rocker button to the left, the virtual object will move to the left in the virtual scene, and may also remain stationary, jump, and use various functions (such as skills and props); the virtual object 101 may also be Artificial Intelligence (AI) set in a virtual scene fight by training; the virtual object 101 may also be a Non-user Character (NPC) set in the virtual scene interaction; the virtual object 101 may also be an immovable object or a movable object in the virtual scene 100.

In general, the computer programs described above may be any form of application, module or plug-in.

Taking a computer program as an application program as an example, in actual implementation, the terminal 400 is installed and runs with an application program supporting a virtual scene. The application program may be any one of a First-Person Shooting game (FPS), a third-Person Shooting game, a virtual reality application program, a three-dimensional map program, or a multi-player gunfight type live game. The user uses the terminal 400 to operate virtual objects located in a virtual scene for activities including, but not limited to: adjusting at least one of body posture, crawling, walking, running, riding, jumping, driving, picking, shooting, attacking, throwing, building a virtual building. Illustratively, the virtual object may be a virtual character, such as a simulated character or an animated character, among others.

The method for adaptively displaying a virtual scene provided in the embodiment of the present application may be executed by the terminal 400 in fig. 1A alone, or may be executed by the terminal 400 and the server 200 in fig. 1B in cooperation.

Next, a description will be given taking an example in which the terminal 400 in fig. 1A alone performs the adaptive display method of the virtual scene provided in the embodiment of the present application. Referring to fig. 3A, fig. 3A is a schematic flowchart of an adaptive display method of a virtual scene provided in an embodiment of the present application, and will be described with reference to the steps shown in fig. 3A.

For example, when the first parameter is a graphics processing performance parameter, determining a plurality of detail level models adapted to the graphics processing performance parameter of the virtual scene, then determining a target detail level model adapted to a camera position parameter of the virtual scene from the plurality of detail level models, and displaying a virtual object in the virtual scene in the field of view of the camera according to the target detail level model; when the first parameter is the camera position parameter, a plurality of detail level models which are matched with the camera position parameter of the virtual scene are determined, then a target detail level model which is matched with the graph processing performance parameter of the virtual scene is determined from the plurality of detail level models, and a virtual object which is positioned in the visual field of the camera in the virtual scene is displayed according to the target detail level model.

In some embodiments, the camera distance parameter is one of: a distance between a camera of the virtual scene and a virtual object in a field of view of the camera; the vertical distance between the camera and the plane of the virtual scene (e.g., reference plane such as virtual ground, virtual water surface, virtual sky, etc.); the difference in the vertical distance between the camera and the plane of the virtual scene and the height of the virtual object.

For example, when the height of the virtual object in the virtual scene is small, the height of the virtual object in the virtual scene may be ignored in calculating the camera distance parameter, thereby increasing the calculation rate of the camera distance parameter.

The following description takes the first parameter as the graphics processing performance parameter as an example:

referring to fig. 3B, fig. 3B is an optional flowchart of a method for adaptively displaying a virtual scene according to an embodiment of the present application, and fig. 3B illustrates that step 101 in fig. 3A may be implemented by steps 1011 to 1012: in step 1011, when the first parameter is a graphic processing performance parameter, a performance parameter configuration file is obtained, wherein the performance parameter configuration file includes an association relationship between different graphic processing performance parameters and different detail level models; in step 1012, the performance parameter configuration file is queried based on the graphics processing performance parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphics processing performance parameters of the virtual scene.

For example, the association relationship between different graphics processing performance parameters and different detail level models is configured in advance and stored in a performance parameter configuration file, after the graphics processing performance parameters of the virtual scene are obtained, the association relationship between the different graphics processing performance parameters and the different detail level models included in the performance parameter configuration file is inquired based on the graphics processing performance parameters of the virtual scene so as to inquire a plurality of detail level models adapted to the graphics processing performance parameters of the virtual scene, then the plurality of detail level models are further screened by combining the camera distance parameters so as to obtain a target detail level model adapted to the camera distance parameters and the graphics processing performance parameters, and all virtual objects in the virtual scene are displayed based on the target detail level model.

As an example, the graphics processing performance parameter of the virtual scene is high performance, and the performance parameter configuration file is queried based on the graphics processing performance parameter of the virtual scene, so that the multiple detail level models adapted to the graphics processing performance parameter of the virtual scene are lod1, lod2, and lod 3.

For example, the embodiment of the present application may display all virtual objects in the virtual scene based on the determined target level of detail model, for example, the level of detail of the virtual object 1 is lod1, and the level of detail of the virtual object 2 is lod 1; the embodiment of the present application may further perform personalized setting on the virtual objects in the virtual scene, that is, different virtual objects may be displayed by different degrees of detail, for example, the degree of detail of the virtual object 1 is lod1, and the degree of detail of the virtual object 2 is lod 2.

It should be noted that, by configuring the configuration table by dividing the virtual object, a plurality of configuration tables can be configured at the same time, thereby speeding up the configuration efficiency and facilitating the lookup of the configuration information of the detail level model.

In some embodiments, the performance parameter profile includes associations of different graphics processing performance parameters to different level of detail models for different virtual objects; inquiring a performance parameter configuration file based on the graphic processing performance parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing performance parameters of the virtual scene, wherein the detail level models comprise: and inquiring the performance parameter configuration file based on the virtual object in the virtual scene and the graphic processing performance parameter of the virtual scene to obtain a plurality of detail level models which are matched with the graphic processing performance parameter and the virtual object of the virtual scene.

According to the situation that the virtual object in the virtual scene is set in an individualized mode, the incidence relation between different graphic processing performance parameters and different detail level models for the different virtual objects is configured in advance and stored in a performance parameter configuration file, after the graphic processing performance parameters of the virtual scene are obtained, the performance parameter configuration file is inquired on the basis of the virtual object in the virtual scene and the graphic processing performance parameters of the virtual scene so as to inquire a plurality of detail level models matched with the graphic processing performance parameters and the virtual objects of the virtual scene, the detail level models are further screened in combination with the camera distance parameters subsequently so as to obtain a target detail level model matched with the camera distance parameters and the graphic processing performance parameters, and the virtual object in the virtual scene is displayed on the basis of the target detail level model.

In some embodiments, the graphics processing performance parameters include graphics processing hardware parameters, and the performance parameter configuration file includes associations of different graphics processing hardware parameters to different level of detail models; inquiring a performance parameter configuration file based on the graphic processing performance parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing performance parameters of the virtual scene, wherein the detail level models comprise: before the virtual scene operation is finished, inquiring a performance parameter configuration file based on the graphic processing hardware parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing hardware parameters of the virtual scene; the hardware parameters of the graphic processing are inquired according to the model of the electronic equipment displaying the virtual scene, and the hardware parameters of the graphic processing comprise at least one of the following parameters: processor model, memory capacity.

For example, the processor includes a central processing unit, a graphics processing unit, and the like, processors of different models, memories of different capacities, and the speed of running software is different, and when the virtual scene starts running or runs, the performance parameter configuration file is queried based on the graphics processing hardware parameters of the virtual scene, so as to obtain a plurality of detail level models adapted to the graphics processing hardware parameters of the virtual scene, for example, when the memory capacity of the electronic device displaying the virtual scene is large and the processor capability is strong, the detail level of the plurality of detail level models adapted to the graphics processing hardware parameters of the virtual scene is high.

In some embodiments, the graphics processing performance parameters comprise graphics processing software parameters, and the performance parameter configuration file comprises associations of different graphics processing software parameters to different level of detail models; inquiring a performance parameter configuration file based on the graphic processing performance parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing performance parameters of the virtual scene, wherein the detail level models comprise: inquiring a performance parameter configuration file based on the parameters of the graphic processing software during the virtual scene operation to obtain a plurality of detail level models which are matched with the parameters of the graphic processing software during the virtual scene operation; wherein the graphics processing software parameters include at least one of: memory free capacity, processor free computing power.

For example, the processor includes a central processing unit, a graphics processing unit, and the like, when the electronic device runs software, the speed of running the software is different, and during the running of the virtual scene, the performance parameter configuration file is queried based on the graphics processing software parameters of the virtual scene, so as to obtain a plurality of detail level models adapted to the graphics processing software parameters of the virtual scene in real time. The computing power depends on the number of cores, the frequency of the cores, the core single clock cycle, and the like.

In some embodiments, the graphics processing performance parameters include graphics processing software parameters and graphics processing hardware parameters, the performance parameter configuration file includes first associations of different graphics processing hardware parameters to different level of detail models, second associations of different graphics processing software parameters to different level of detail models; inquiring a performance parameter configuration file based on the graphic processing performance parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing performance parameters of the virtual scene, wherein the detail level models comprise: when the graphic processing software parameters of the virtual scene are larger than the performance threshold, inquiring a first incidence relation included in a performance parameter configuration file based on the graphic processing hardware parameters of the virtual scene to obtain a plurality of detail level models adapted to the graphic processing hardware parameters of the virtual scene; and when the graphic processing software parameters of the virtual scene are smaller than or equal to the performance threshold, inquiring a second incidence relation included in the performance parameter configuration file based on the graphic processing hardware parameters during the virtual scene operation to obtain a plurality of detail level models adapted to the graphic processing software parameters during the virtual scene operation.

For example, when the graphics processing software parameter of the virtual scene is greater than the performance threshold, it is indicated that the speed of the software running is relatively fast, at this time, a plurality of detail level models adapted to the graphics processing hardware parameter of the virtual scene can be completely inquired according to the first association relationship between different graphics processing hardware parameters and different detail level models, and the detail level models adapted to the graphics processing hardware parameter of the virtual scene can meet the smoothness of the virtual scene running; when the graphic processing software parameters of the virtual scene are less than or equal to the performance threshold, it is indicated that the speed of the operating software is slow, and at this time, a plurality of detail level models which are adapted to the graphic processing software parameters of the virtual scene in real time need to be inquired according to the second association relationship between different graphic processing software parameters and different detail level models, and the detail level models which are adapted to the graphic processing software parameters of the virtual scene can meet the smoothness of the operation of the virtual scene.

In step 102, a target level of detail model which is adapted to a second parameter of the virtual scene is determined from the plurality of level of detail models; wherein the second parameter is the other of the camera distance parameter and the graphics processing performance parameter other than the first parameter.

Taking the second parameter as the camera distance parameter as an example, after a plurality of detail level models which are adaptive to the graphic processing performance parameter of the virtual scene are determined, a target detail level model which is adaptive to the camera position parameter of the virtual scene is determined from the plurality of detail level models, and a virtual object which is positioned in the visual field of the camera in the virtual scene is displayed according to the target detail level model, so that the detail degree presented by the virtual object meets the actual requirement under the condition that the virtual scene is ensured to operate smoothly.

The following description will be given taking the second parameter as the camera distance parameter as an example:

in some embodiments, when the second parameter is a camera distance parameter, determining a target level of detail model adapted to the second parameter of the virtual scene from the plurality of level of detail models comprises: acquiring a distance parameter configuration file, wherein the distance parameter configuration file comprises incidence relations between different camera distance parameters and different detail level models; and inquiring a distance parameter configuration file based on the camera distance parameter of the virtual scene to obtain a target detail level model matched with the camera distance parameter of the virtual scene.

For example, the association relations between different camera distance parameters and different detail level models are configured in advance and stored in a distance parameter configuration file, after the camera distance parameters of the virtual scene are obtained, the association relations between the different camera distance parameters and the different detail level models included in the distance parameter configuration file are inquired based on the camera distance parameters of the virtual scene so as to inquire a target detail level model adapted to the second parameters of the virtual scene, and therefore the target detail level model adapted to the camera distance parameters and the graphic processing performance parameters is obtained, and all virtual objects in the virtual scene are displayed based on the target detail level model.

In some embodiments, the distance parameter configuration file includes association relations between different camera distance intervals and different detail level models, and the camera distance intervals are obtained by dividing value intervals of camera distance parameters; inquiring a distance parameter configuration file based on the camera distance parameter of the virtual scene to obtain a target detail level model adaptive to the camera distance parameter of the virtual scene, wherein the target detail level model comprises the following steps: inquiring a camera distance interval included in the distance parameter configuration file based on the camera distance parameter of the virtual scene to obtain a camera distance interval corresponding to the camera distance parameter of the virtual scene; based on the camera distance interval corresponding to the camera distance of the virtual scene, the incidence relation between different camera distance intervals and different detail level models included in the distance parameter configuration file is inquired, and a target detail level model adaptive to the camera distance parameters of the virtual scene is obtained.

For example, according to the actual display requirement of the virtual object, dividing the value intervals of the camera distance parameters to obtain a plurality of camera distance intervals, pre-configuring the association relations between different camera distance intervals and different detail level models, storing the association relations in a distance parameter configuration file, after obtaining the camera distance parameters of the virtual scene, firstly inquiring the camera distance intervals included in the distance parameter configuration file based on the camera distance parameters of the virtual scene, and inquiring the camera distance intervals corresponding to the camera distance parameters of the virtual scene; based on the camera distance interval corresponding to the camera distance of the virtual scene, the incidence relation between different camera distance intervals and different detail level models included in the distance parameter configuration file is inquired, and the target detail level model matched with the camera distance parameters of the virtual scene is inquired.

In step 103, virtual objects in the virtual scene that are in the field of view of the camera are displayed according to the target level of detail model.

For example, after a target detail level model adapted to a camera distance parameter and a graphic processing performance parameter is determined, all virtual objects in a virtual scene are displayed based on the target detail level model, so that the detail degree presented by the virtual objects meets the actual requirement under the condition of ensuring smooth operation of the virtual scene.

For example, a user representation corresponding to an account controlling a virtual object in a virtual scene may be counted by historical data. And performing prediction processing on the detail level model by combining the detail level preference model with a plurality of detail level models which are adaptive to the second parameter of the virtual scene and the user portrait to obtain a detail level model (namely a target detail level model) which is possibly preferred by the account. The preference model of the level of detail can be a trained neural network model, and the neural network model can be obtained by training a plurality of samples of the model of the level of detail, samples of the portrait of the user and samples of the model of the target level of detail.

In some embodiments, when there are a plurality of level of detail models adapted to the second parameter of the virtual scene, acquiring a complexity level of a virtual object in the virtual scene that is located in a field of view of the camera; and calling a detail level prediction model based on a plurality of detail level models which are adaptive to the second parameter of the virtual scene and the complexity degree to obtain a target detail level model.

For example, the level of detail preference model is combined with a plurality of level of detail models adapted to the second parameter of the virtual scene and the complexity to perform prediction processing on the level of detail models, so as to obtain an appropriate level of detail model (i.e. a target level of detail model). The detail level preference model may be a trained neural network model, and the neural network model may be obtained by training a plurality of detail level model samples, virtual object samples, and target detail level model samples.

In some embodiments, displaying a virtual object in a virtual scene that is in a field of view of a camera according to a target level of detail model includes: obtaining model parameters of a target detail level model, wherein the model parameters comprise model meshes and model materials; and displaying a virtual object positioned in the visual field of the camera in the virtual scene according to the model parameters.

For example, after the target detail level model is determined, the model parameters of the target detail level model are loaded, so that the virtual object in the visual field of the camera in the virtual scene is displayed according to the model parameters acquired in real time, and the virtual object can be immediately taken and used, so that the phenomenon that the model parameters are loaded in advance and the storage space is occupied is avoided.

In some embodiments, before displaying a virtual object in a field of view of a camera in a virtual scene according to a target level of detail model, obtaining model parameters for each level of detail model, wherein the model parameters include a model mesh and a model material; storing the model parameters of each detail level model to a cache space; displaying a virtual object in a virtual scene that is in a field of view of a camera according to a target level of detail model, comprising: obtaining model parameters of a target detail level model from a cache space; and displaying a virtual object in the virtual scene, which is positioned in the visual field of the camera, according to the model parameters of the target detail level model.

For example, the model parameters of each detail level model are loaded in advance, and after the target detail level model is determined, the model parameters of the target detail level model are obtained from the cache space in time; and displaying the virtual object positioned in the visual field of the camera in the virtual scene according to the model parameters of the target detail level model, thereby saving the loading time of the model parameters when the virtual object needs to be displayed.

In summary, the adaptive display method for the virtual scene provided in the embodiment of the present application determines the accurate and adaptive target detail level model by combining the two parameters, i.e., the camera position parameter and the graphics processing performance parameter, of the virtual scene, so that the smooth switching of the virtual object is performed based on the accurate and adaptive target detail level model, the human-computer interaction effect of the virtual scene is improved, and related communication resources and computing resources are saved.

Next, a description will be given taking an example in which the terminal 400 in fig. 1A alone performs the adaptive display method of the virtual scene provided in the embodiment of the present application. Referring to fig. 3C, fig. 3C is a schematic flowchart of an adaptive display method of a virtual scene provided in an embodiment of the present application, and will be described with reference to the steps shown in fig. 3C.

It should be noted that the method shown in fig. 3C may be executed by various forms of computer programs running on the terminal 400, and is not limited to the client 410 described above, but may also be the operating system 461, software modules and scripts described above, so that the client should not be considered as limiting the embodiments of the present application.

In step 201, a virtual object in the virtual scene that is in the field of view of the camera is displayed based on the first level of detail model.

For example, the first level of detail model is adapted to the current vertical distance, and virtual objects in the virtual scene that are in the field of view of the camera are displayed by the level of detail model adapted to the current vertical distance.

As shown in fig. 4B, when the current vertical distance is a medium distance, the camera is closer to the mountain 401 (i.e., the virtual object), and the details of the mountain 401 can be clearly seen.

In step 202, in response to a change in the vertical distance of the camera relative to the plane of the virtual scene, updating a virtual object in the virtual scene that is in the field of view of the camera based on the second level of detail model; wherein the level of detail of the second level of detail model is inversely related to the changed vertical distance.

For example, when the vertical distance of the camera with respect to the plane of the virtual scene is shorter, the virtual object in the visual field of the camera in the virtual scene is updated and displayed based on the second level-of-detail model, and the level of detail of the virtual object after updating and displaying is higher, as shown in fig. 4A, the camera is very close to the mountain 401, a great amount of detail of the mountain 401 can be clearly seen, and compared with fig. 4B, the number of the model surfaces included in the mountain in fig. 4A is increased, and the model material is better; when the vertical distance of the camera relative to the plane of the virtual scene is longer, the virtual object positioned in the visual field of the camera in the virtual scene is updated and displayed based on the second level-of-detail model, and the detail degree of the virtual object after updating and displaying is lower, as shown in fig. 4C, the camera is far away from the mountain 401, partial details of the mountain 401 can be seen, and compared with fig. 4B, the number of the model surfaces contained in the mountain in fig. 4C is reduced, and the model material is also simplified.

In some embodiments, the vertical distance of the camera relative to the plane of the virtual scene is one of: a vertical distance between the camera and a plane of the virtual scene; the difference in the vertical distance between the camera and the plane of the virtual scene and the height of the virtual object.

In some embodiments, prior to updating the virtual object in the field of view of the camera in the display virtual scene based on the second level of detail model, determining a plurality of level of detail models that are adapted to graphics processing performance parameters of the virtual scene; from the plurality of level of detail models, a second level of detail model is determined that fits the changed vertical distance.

For example, a plurality of detail level models adapted to the graphics processing performance parameters of the virtual scene are determined, then a second detail level model adapted to the changed vertical distance is determined from the plurality of detail level models, and the virtual object in the virtual scene in the visual field of the camera is updated and displayed according to the second detail level model, so that the accurate second detail level model is adapted in combination with the distance parameters of the camera and the graphics processing performance parameters, and the details of the virtual object in the virtual scene are reflected on the basis of the appropriate second detail level model.

In some embodiments, prior to updating the virtual object in the field of view of the camera in the displayed virtual scene based on the second level of detail model, determining a plurality of level of detail models that fit the changed vertical distance; from the plurality of level of detail models, a second level of detail model is determined that is adapted to graphics processing performance parameters of the virtual scene.

For example, a plurality of detail level models adapted to the changed vertical distance are determined, then a second detail level model adapted to the graphics processing performance parameters of the virtual scene is determined from the plurality of detail level models, and the virtual object in the virtual scene in the visual field of the camera is updated and displayed according to the second detail level model, so that the accurate second detail level model is adapted in combination with the distance parameters and the graphics processing performance parameters of the camera, and the details of the virtual object in the virtual scene are reflected on the basis of the appropriate second detail level model.

It should be noted that the process of adapting to the graphics processing performance parameter of the virtual scene and the process of adapting to the vertical distance are similar to the process of adapting to the above-described embodiment.

In summary, the adaptive display method for the virtual scene provided in the embodiment of the present application determines the adaptive detail level model quickly by using the parameter of the vertical distance between the camera and the plane of the virtual scene, so that the smooth switching of the virtual object is performed based on the adaptive detail level model, the human-computer interaction effect of the virtual scene is improved, and the related communication resources and the computing resources are saved.

Next, an exemplary application of the embodiment of the present application in a practical application scenario will be described.

The following description takes a virtual scene as an example:

in the related art, the load solution provided by Unity loads all model meshes (mesh) and model materials at the beginning of a game, and the overhead on a memory is increased. In addition, the Lodgroup scheme also fails to solve the problem of model lod.

In order to solve the above problem, an embodiment of the present application provides an adaptive display method for a virtual scene, which can be used for a model lod and a distance lod. The method is used for adapting to different models and loading models with different detail degrees (namely different level models) at different distances so as to improve the running performance of the game; the adaptive display method for the virtual scene, provided by the embodiment of the application, can reload the model mesh and the model material included in the lod when the lod is needed, switch to display the lod after the lod is loaded, and can also preload in advance; in the embodiment of the application, when the game runs, the corresponding configuration file is determined according to the model, and then the configuration file is inquired according to the vertical distance to switch different lods.

It should be noted that more and more SLG games are top-down, and the whole world in the game is observed by changing the position and height of the camera. Taking a scene as a mountain as an example, as shown in fig. 4A, under a high-end machine and a low viewing angle, a camera is close to a mountain 401, and a great deal of details of the mountain 401 can be clearly seen, that is, a game mountain includes a great number of triangular meshes; as shown in fig. 4B, at a medium viewing angle in a high-end camera, the camera is closer to the mountain 401, and the details of the mountain 401 can still be clearly seen; as shown in fig. 4C, the camera is far from the mountain 401 under the high viewing angle of the high-end machine, and can see part of the details of the mountain 401, and compared with fig. 4A, the number of the model surfaces included in the mountain in fig. 4C is reduced, and the model material is also simplified; as shown in fig. 4D, the camera is close to the mountain 401 at a low viewing angle of the low-end camera, so that a lot of details of the mountain 401 can be clearly seen, and compared with fig. 4A, the number of model surfaces included in the mountain in fig. 4C is reduced, but the details are seen with the naked eye to be as good as the effect of the high-end camera.

It should be noted that the art designer creates LOD providing different models and names LOD01, LOD02, LOD03, LOD04, etc., and the model mesh (mesh) and model material are named in this way, such as xxx _01.mesh, xxx _02.mesh, xxx _03.mesh, xxx _01.mat, xxx _02.mat, xxx _03.mat, etc. The model details of lod are sequentially from high to low and exist in the form of prefab, and the prefab is associated with the corresponding mesh and the model material.

In addition, the embodiment of the present application provides a configuration tool, which can be used by an art designer to configure the model lod and the distance lod, for example, configuration items shown in table 1 and table 2 are provided.

TABLE 1

TABLE 2

The above configuration is explained below:

1) MainCity in Table 1, Hill in Table 2 is the module name, and MC _ Hav01_01 is the prefix of prefab in the module interior, placed in the first column of the resource menu bar shown in Table 1, where the suffix 01, 02, 03, 04 of MC _ Hav01_01 is the index of lod.

2) S, A, B, C are model classes, which respectively represent extreme, high, medium and low, S1, S2 and S3 respectively represent different height levels (which are divided according to the distance in actual use), and respectively represent low, medium and high. Different models lod are configured, the model lod can be flexibly expanded to an N gear, the maximum N gear can be matched with the maximum model gear of the client, and as shown in fig. 5, the model lod is flexibly expanded to an S gear 501, an A gear 502, a B gear 503 and a C gear 504.

3) There are three items of distance lod at S1 as shown in table 1, namely, one item of distance lod at lod1, lod2, lod3, S2 and S3, as shown in fig. 6, "+" 601 is used to add distance lod, "x" 602 is used to delete distance lod, "resource" column is prefix of prefab of lod, "distance value" column is maximum display distance of object from camera, beyond which distance is not displayed, if there is next layer, it is automatically switched to lod of next layer. Wherein different models lod can be repeated.

It should be noted that, because the game is a depression, the actual distance of the camera is reduced to the vertical distance between the object (i.e. the virtual object in the game) and the camera, so that the calculation overhead of the central processing unit can be reduced. Of course, if one wants to use for non-top down games, it is also possible to simply change the vertical distance to the actual distance, just a little bit more computationally and code complexity.

As shown in fig. 7, after the art designer completes configuration, the "save LOD configuration" button 701 is clicked to save the LOD configuration and generate 2 configuration files, one of which is information about a configuration tool of the art designer and one of which is a configuration file of the LOD model class provided to the client.

Information about the configuration tool of the art designer: as shown in fig. 8, the configuration items are configured and stored according to the divided module profiles, so that the art designer can edit different modules at the same time, and the modules are convenient to look up.

Regarding the binning configuration (lodddevicecfg): different files are divided according to different model gears, namely LodDeviceCfg-S, LodDeviceCfg-A, LodDeviceCfg-B, LodDeviceCfg-C.

When the game runs, corresponding configuration files are selected according to different models, and different lods are switched according to the vertical distance, wherein the specific flow is shown in fig. 9:

and step 11, judging the model after the game is started.

And step 12, reading the lod configuration of the corresponding model.

And step 13, loading the model configuration of the corresponding land parcel in the visual field after the camera moves. For example, when a camera is moved to a particular location, the corresponding model configuration is loaded based on the model information stored in the parcel.

And step 14, reading the lod configuration according to the model ID to acquire a corresponding configuration item.

And step 15, loading the model of the corresponding layer according to the current height of the camera.

And step 16, judging whether the model needs to be switched or not when the height of the camera (namely the vertical distance between the object and the camera) changes, and switching lod when the height is not in the current height range.

For example, when the level of the height of the camera is greater than or equal to the current level, loading the previous model, displaying the previous model, and hiding the current level; and when the level of the height of the camera is smaller than the current level and smaller than or equal to the next level, loading the next level model, displaying the next level model and hiding the current level.

Because the loading is asynchronous, after the loading is finished, whether the current vertical distance is within the distance range of the current lod needs to be judged again, and if the current vertical distance is not within the distance range of the current lod, the switching needs to be continued.

Note that, when attribute information (transform) such as coordinates, scaling, and rotation differs for the same model, the corresponding model can be acquired from the lod system, and the transform can be processed as follows.

a. If the object is not suitable for instantiation (gpu instance) processing by an image processor, instantiation is required, and transform information in the instance is modified;

b. if the object is suitable for processing with gpu instance, then instantiation is not required and transform information can be converted to the object's Matrix4x4 for processing.

In summary, the adaptive display method for the virtual scene provided by the embodiment of the application has the following beneficial effects:

1) the distance between the object model (the model corresponding to the object) and the camera is calculated simply, namely the actual distance is reduced to the vertical height of the camera minus the vertical height of the object model, and if the object model is small, the vertical height of the object model can be ignored, so that the distance calculation of the embodiment of the application is simple and efficient, and is suitable for most SLG games.

2) According to the method and the device, the model mesh and the model material included by the lod are loaded when the lod is needed, and seamless switching is performed after the lod is loaded, so that the memory overhead is reduced.

3) The embodiment of the application can process the model lod and the distance lod, can conveniently expand the model lod and the distance lod, and can better meet the actual project requirements.
