Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

1) Virtual scene

A virtual scene is a virtual scene that an application program displays (or provides) while running on a terminal. The virtual scene can be a simulation environment scene of a real world, a half-simulation half-fictional three-dimensional environment scene, or a pure fictional three-dimensional environment scene. The virtual scene may be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene, and a three-dimensional virtual scene, and the following embodiments are exemplified by the virtual scene being a three-dimensional virtual scene, but are not limited thereto. Optionally, the virtual scene may also be used for virtual scene fight between at least two virtual characters. Optionally, the virtual scene may also be used to fight between at least two virtual characters using a virtual firearm. Optionally, the virtual scene may be further operable to use the virtual firearm to fight between at least two virtual characters within a target area range that is continuously smaller over time in the virtual scene. Virtual scenes are typically presented by application generation in a computer device such as a terminal based on hardware (such as a screen) in the terminal. The terminal can be a mobile terminal such as a smart phone, a tablet computer or an electronic book reader; alternatively, the terminal may be a notebook computer or a personal computer device of a stationary computer.

2) Virtual object

Virtual objects refer to movable objects in a virtual scene. The movable object may be at least one of a virtual character, a virtual animal, a virtual vehicle. Alternatively, when the virtual scene is a three-dimensional virtual scene, the virtual object is a three-dimensional stereoscopic model created based on an animated skeleton technique. Each virtual object has its own shape, volume, and orientation in the three-dimensional virtual scene and occupies a portion of the space in the three-dimensional virtual scene.

3) Multiple levels of detail

Multiple Detail Levels (LOD), the LOD refers to determining the resource allocation of object rendering according to the position and importance of the nodes of the object model in the display environment, and reducing the number of planes and the Detail of non-important objects, so as to obtain efficient rendering operation. In general, the lower the LOD level, the more important the object model, whereas the higher the LOD level, the less important the object model.

4) Skeletal animation LOD

The skeletal animation LOD is to determine the detail level of playing the skeletal animation according to the distance between the virtual object playing the skeletal animation and the virtual camera and the importance level of the virtual object. In general, for virtual objects far away from the virtual camera or not important, a manner of simplifying a skeleton or reducing the updating frequency of the animation can be adopted to solve the problem of game performance brought in the skeleton animation rendering process.

5) Screen space rendering size

In the UE4 (the virtual Engine 4), the size of the skeletal animation mesh body on the screen may be identified using the rendering size of the skeletal animation mesh body in the screen space, and the LOD level corresponding to the virtual object may be determined according to the size value. In general, the farther a virtual object is from a virtual camera, the smaller the rendering size on the screen, the larger the LOD level; conversely, the closer the virtual object is to the virtual camera, the larger the rendered size on the screen, and the smaller the LOD level.

6) Animation update interval

The animation update interval may also be referred to as a skeletal animation update interval frame number. The skeletal animation update interval frame number is the frame number of the interval between two skeletal animation updates. If the skeleton animation update interval frame number is 0, the skeleton animation is indicated to be updated every frame. In general, the animation update interval may be converted into an animation update frequency, and the smaller the animation update interval, the higher the animation update frequency, and the smaller the frame number of the skeleton animation update interval.

Referring to fig. 1, a schematic diagram of a skeletal animation updating system according to an embodiment of the present application is shown. The system may include: computer device 110, terminal 120, and server 140.

The computer device 110 is a terminal corresponding to a developer, on which a development and editing platform for supporting an application program of a virtual environment is installed, the developer can edit and update the application program on the terminal, and transmit an updated application program installation package to the server 140 through a wired or wireless network, and the terminal 120 can download the application program installation package from the server 140 to implement update of the application program.

The terminal 120 installs and runs an application supporting a virtual environment, which may be a multi-person online fight program. When the terminal 120 runs the application, a user interface of the application is displayed on a screen of the terminal 120. The application may be any of a multiplayer online tactical Game (Multiplayer Online Battle Arena Games, MOBA), a fleeing Game, a simulated strategy Game (SLG). The terminal 120 is a terminal used by a first user, and the first user uses the terminal 120 to control a first virtual object located in a virtual scene to perform activities, where the first virtual object may be referred to as a master virtual object of the first user. The activities of the first virtual object include, but are not limited to: adjusting at least one of body posture, climbing, crawling, walking, running, riding, flying, jumping, driving, picking up, shooting, attacking, throwing, releasing skills. Illustratively, the first virtual object is a first virtual character, such as an emulated character or a cartoon character. The device types of the terminal 120 include: at least one of a smart phone, a tablet computer, an electronic book reader, an MP3 player, an MP4 player, a laptop portable computer, and a desktop computer. Only one terminal is shown in fig. 1, but in different embodiments there are a number of other terminals that can access the server 140.

The computer device 110 and the terminal 120 are connected to the server 140 via a wireless network or a wired network.

Server 140 includes at least one of a server, a server cluster formed by a plurality of servers, a cloud computing platform, and a virtualization center. The server 140 is used to provide background services for applications supporting a three-dimensional virtual environment. Optionally, the server 140 takes on primary computing work and the terminal takes on secondary computing work; alternatively, the server 140 takes on secondary computing work and the terminal takes on primary computing work; alternatively, a distributed computing architecture is used between the server 140 and the terminal for collaborative computing. The virtual scene may be a three-dimensional virtual scene, or the virtual scene may be a two-dimensional virtual scene. The following embodiment takes as an example that the virtual scene is a three-dimensional virtual scene.

In the related art, the problem of influencing game performance when a skeletal animation is displayed is solved. The LOD levels of the virtual objects need to be distinguished, in one case, when the LOD levels of the virtual objects are higher, the performance problem of exhibiting the skeletal animation can be solved by replacing a simpler skeletal model and animation resources with the virtual objects; and when the LOD level of the virtual object is lower, more complex and fine skeleton models and finer skeleton animation resources can be used interchangeably to ensure skeleton animation expression effects in the virtual scene. According to the scheme, skeleton models and corresponding animation resources for replacement, which correspond to different LOD levels, are required to be manufactured for different virtual objects, so that on one hand, the manufacturing cost of skeleton animation is improved, and on the other hand, as resources, which need to be replaced, of different LOD levels are required to be loaded into a memory during operation, additional memory overhead is brought to the virtual scene during operation.

In another case, when the LOD level of the virtual object is higher, the skeleton animation update frequency of the skeleton model of the whole virtual object can be reduced; and when the LOD level of the virtual object is lower, the normal skeleton animation updating frequency of the virtual object can be restored. Under the scheme, when the LOD level of the virtual object is lower, if the animation update rate of the whole skeleton model of the virtual object is limited, the animation of the virtual object is relatively stagnant, so that the expression effect of the skeleton animation is affected; if the overall animation update frequency of the virtual object is not limited, the performance problem in the process of actually displaying the skeleton animation can not be solved, and meanwhile, in the actual application process, the balance between the performance and the animation expression effect is difficult to obtain.

According to the skeleton animation updating method, a first scene picture is displayed in a virtual scene interface, wherein the first scene picture comprises a first virtual object with at least one skeleton group, and the respective animation updating interval of the at least one skeleton group in the skeleton animation is determined based on the rendering size of the skeleton group, so that the skeleton animation of the first virtual object is updated. Referring to fig. 2, a schematic diagram of a bone animation update procedure according to an exemplary embodiment of the present application is shown. The method may be performed by a computer device, which may be a terminal or a server. As shown in fig. 2, the computer device may update the skeletal animation of the virtual object in the virtual scene by performing the following steps.

Step 201, displaying a virtual scene interface, where the virtual scene interface is used to display a picture obtained by shooting a virtual scene with a virtual camera.

In the embodiment of the application, the terminal displays a virtual scene display interface obtained by shooting a virtual scene through a virtual camera on a display screen.

Step 202, a first scene picture is displayed in the virtual scene interface, wherein the first scene picture contains a first virtual object, and the first virtual object corresponds to at least one skeleton group.

In the embodiment of the application, the terminal displays a first scene picture containing a first virtual object in a virtual scene display interface.

The first virtual object may be a virtual object controlled by a terminal, or may be a virtual object controlled by another terminal or an application program.

In one possible implementation manner, the first virtual object is displayed in the virtual scene in the three-dimensional environment through a constructed three-dimensional model, and the three-dimensional model comprises a skeleton model of the first virtual object and is used for simulating a skeleton structure in reality, so that the first virtual object is controlled to flexibly execute various actions.

The skeleton model is composed of at least one skeleton group, and each skeleton corresponding to the at least one skeleton group is matched with each other to control the first virtual object to execute each action, and each action is displayed in a skeleton animation updating mode. Any one bone group includes at least one parent bone and at least one child bone.

Since the skeleton animation update operation corresponding to a skeleton is usually performed in a local space of the skeleton, the transformation data of a child skeleton in world space depends on all its parents, and all its parents must participate in the update at this time in order to ensure that the child skeleton obtains the correct transformation result. Similarly, when one sub-skeleton decides that the current frame is to skip updating, if a certain sub-skeleton thereof decides to update, the transform data obtained by that sub-skeleton is problematic. In executing the bone animation, it is necessary to execute the decision logic of whether or not the frame is to update the bone animation of the corresponding bone group in order from the parent bone to the child bone. That is, when a parent bone decides to skip updating the corresponding bone animation, all child bones in the bone group no longer update the bone animation when a frame, and other child bones in the bone group are not required to perform subsequent decision logic of whether to update the bone animation. Similarly, when a skeleton determines that the current frame is to perform updating of the skeleton animation, all parent skeletons corresponding to the skeleton cannot skip updating of the skeleton animation corresponding to the skeleton group.

Step 203, in the first scene picture, updating the skeleton animation of the first virtual object; at least one skeleton group has a respective animation update interval in the skeleton animation, and the animation update interval of the skeleton group is inversely related to the rendering size of the skeleton group.

In the embodiment of the present application, in a first scene, a rendering size corresponding to a skeleton group is acquired, an animation update interval corresponding to the skeleton group with which the rendering size is inversely related is determined, and based on respective animation update intervals of at least one skeleton group in skeleton animations, the skeleton animations of each skeleton group in a first virtual object are updated, so that the skeleton animations of the first virtual object are updated.

In one possible implementation manner, the skeleton model corresponding to the first virtual object at least includes one skeleton group needing to perform the skeleton animation LOD, and the skeleton not included in the skeleton group needing to perform the skeleton animation LOD is set to perform animation update every frame.

In summary, according to the scheme shown in the embodiment of the present application, by acquiring the rendering size corresponding to at least one skeleton group of the first virtual object, determining the respective animation update interval of at least one skeleton group negatively related to the rendering size in the skeleton animation, and then updating the skeleton animation of the first virtual object based on the animation update interval, so that when the skeleton animation is updated, the frequency of updating the skeleton animation can be different through different skeleton groups, for the skeleton group with a larger rendering size, a higher frequency refresh is used, a display effect is ensured, for the skeleton group with a smaller rendering size, a lower frequency refresh is used, and therefore, processing resources and electric quantity resources are saved, and the consumption of processing resources and electric quantity resources is reduced while the display effect of the skeleton animation of the virtual object is ensured.

Referring to fig. 3, a method flowchart of a bone animation update method according to an exemplary embodiment of the present application is shown. The method may be performed by a computer device, which may be a terminal or a server. As shown in fig. 3, taking a computer device as an example of a terminal, the terminal may update a skeletal animation of a virtual object in a virtual scene by performing the following steps.

Step 301, a first scene picture is displayed in a virtual scene interface.

In the embodiment of the application, the terminal displays the virtual scene interface in response to the start of the operation of the virtual scene, and then displays the first scene picture when the virtual camera observes that the first virtual object exists in the virtual scene.

The virtual scene interface is used for displaying pictures obtained by shooting virtual scenes through the virtual camera. The first scene picture comprises a first virtual object, and the first virtual object corresponds to at least one skeleton group.

In one possible implementation, the bone group in the bone model is at least one of a stem bone group and a terminal bone group.

The skeleton groups of the trunk are skeleton groups near the root in skeleton trees corresponding to the skeleton models, and the skeleton groups of the tail ends are skeleton groups near leaf nodes in the skeleton trees.

For example, taking a human skeletal model as an example, the backbone skeleton group may include at least one of a spine skeleton group, an arm skeleton group, a shoulder skeleton group, a leg skeleton group, and a head skeleton group; the end skeletal set may include at least one of a hand skeletal set, a foot skeletal set, and a apparel portion skeletal set. In addition, the skeletal model of the first virtual object may also be a non-human skeletal model.

Step 302, a first distance between a virtual camera and a first virtual object is obtained.

In the embodiment of the application, the terminal acquires a first distance between the virtual camera and the first virtual object.

Wherein the first distance may be a straight line distance from the virtual camera to a center of gravity of the first virtual object. Alternatively, it may be a vertical distance between the virtual camera and a plane perpendicular to the horizontal ground where the center of gravity of the first virtual object is located.

Step 303, determining rendering sizes corresponding to the at least one skeleton group respectively based on the first distance.

In the embodiment of the application, the terminal determines rendering sizes corresponding to each skeleton group on the skeleton model of the first virtual object based on the acquired first distance.

The terminal determines the rendering size of each skeleton group on the screen space on the skeleton model of the first virtual object based on the acquired first distance.

In one possible implementation, the rendering sizes respectively corresponding to the respective bone groups are related to model sizes respectively corresponding to the respective bone groups in addition to the magnitudes of the first distances.

For example, if a bone group a and a bone group B exist in the bone model of the first virtual object, the model size corresponding to the bone group a is greater than the model size corresponding to the bone group B, when the first virtual object enters the first virtual scene and is observed by the virtual camera, a first distance between the bone group a and the virtual camera and a first distance between the bone group B and the virtual camera are determined, and if the first distance between the bone group a and the virtual camera and the first distance between the bone group B and the virtual camera are equal, the rendering size corresponding to the bone group a is greater than the rendering size corresponding to the bone group B because the model size corresponding to the bone group a is greater than the model size corresponding to the bone group B.

Step 304, determining an animation update interval corresponding to at least one skeleton group based on the rendering sizes corresponding to at least one skeleton group respectively.

In the embodiment of the application, the terminal can determine the animation update interval of each skeleton group in the current frame based on the rendering sizes corresponding to each skeleton group on the obtained skeleton model.

Wherein, the animation update interval refers to the number of frames of the interval between two skeletal animation updates of the skeletal group.

In one possible implementation, a configuration map is obtained, and based on the rendering size, an animation update interval corresponding to each of the at least one skeleton group is determined from the configuration map.

That is, after the terminal obtains the rendering size corresponding to each skeleton group, the terminal searches the animation update interval corresponding to each skeleton group from the configuration mapping table stored in the server.

The configuration mapping table is used for indicating the corresponding relation between the rendering size and the animation updating interval respectively configured by at least one skeleton group.

For example, as shown in table 1 below, if the skeleton model includes skeleton group X, skeleton group Y, and skeleton group Z, the configuration mapping table may indicate that, for all parent skeletons and child skeletons in skeleton group X, when the rendering size of the virtual object corresponding to the rendering size in the screen space is smaller than a, the animation update interval corresponding to each skeleton in skeleton group X is a frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than A and smaller than B, the animation updating interval corresponding to each skeleton in the skeleton group X is B frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than B and smaller than C, the animation updating interval corresponding to each skeleton in the skeleton group X is C frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than C, the animation updating interval corresponding to each skeleton is 0 frames, namely, each frame is subjected to skeleton animation updating. For all the father bones and the child bones in the skeleton group Y, when the rendering size of the virtual object corresponding to the virtual object in the screen space is smaller than D, the animation updating interval corresponding to each bone in the skeleton group Y is D frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than D and smaller than E, the animation updating interval corresponding to each skeleton in the skeleton group Y is E frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than E, the animation updating interval corresponding to each skeleton is 0 frame; for all the father bones and the child bones in the skeleton group Z, when the rendering size of the virtual object corresponding to the virtual object in the screen space is smaller than F, the animation updating interval corresponding to each bone in the skeleton group Z is F frames; when the rendering size of the virtual object corresponding to the virtual object in the screen space is larger than F, the animation updating interval corresponding to each skeleton is 0 frame; generally, if there is a relationship A < B < C, then there is a > B > C; if D < E is present, then D > E is present.

TABLE 1

In one possible implementation, in response to at least one bone group being a first bone group and a second bone group, an animation update interval corresponding to the first bone group and the second bone group, respectively, is determined based on the rendering size and a position of the first bone group and the second bone group in the bone model.

Wherein, under the same rendering size, the distance between the skeleton group and the tail end of the skeleton model is inversely related to the animation updating interval corresponding to the skeleton group.

For example, in configuring the mapping relationship between the rendering size and the animation update interval for each bone group in the bone model of the virtual object, the configuration rule of the mapping relationship may conform to that the animation update interval for a bone group (such as a finger bone group, a toe bone group, a skirt bone group, etc.) closer to the end of the bone model is smaller as the animation update interval for a bone group (such as a torso bone group, a leg bone group, an arm bone group, etc.) closer to the top of the bone model is larger under the rendering size of the same screen space.

In one possible implementation, in response to the rendering size being less than or equal to a first threshold, the animation update interval corresponding to the end skeleton group is greater than the animation update interval corresponding to the backbone skeleton group; in response to the rendering size being greater than the first threshold, the animation update interval corresponding to the end skeleton group is equal to the animation update interval corresponding to the backbone skeleton group.

For example, if the first distance between the first virtual object and the virtual camera is smaller than the first threshold x, the rendering size of the skeleton model corresponding to the first virtual object in the screen space is smaller than or equal to the specified value, so in this case, in order to reduce the influence of the skeleton animation on the running performance of the virtual scene, the update rate of the skeleton animation should be reduced, at this time, the speed of updating the skeleton animation by the skeleton group at the end position of the skeleton model may be preferentially reduced, and then if the rendering size continues to be reduced, the reduction of the update rate of the skeleton animation by the skeleton group near the end position may be restarted. If the first distance between the first virtual object and the virtual camera is greater than or equal to a first threshold x, that is, the rendering size of the skeleton model corresponding to the first virtual object in the screen space is greater than or equal to a specified value, the skeleton animation needs to be updated more finely, so that the animation display effect of the skeleton animation can be improved by updating the skeleton animation every frame.

In step 305, based on the animation update intervals corresponding to the skeleton groups, the skeleton animation of the first virtual object is updated in the first scene.

In the embodiment of the application, in the process of updating the skeleton animation, the terminal determines the skeleton animation of the updated first virtual object displayed in the first scene based on the obtained animation updating interval corresponding to each skeleton group of the current scene.

In one possible implementation manner, determining an animation execution list corresponding to a current frame picture based on an animation update interval; and updating the skeleton animation corresponding to the first virtual object in the first scene picture based on the animation execution list corresponding to the current frame picture.

The animation execution list includes names of skeleton groups which need to be subjected to skeleton animation updating in a skeleton model corresponding to a first virtual object of the current frame of picture.

In one possible implementation manner, in response to the bone model of the first virtual object including at least the first bone group, and the animation update interval corresponding to the first bone group is the first update interval, first, a first counter value corresponding to the first bone group is detected, then, in response to the first counter value being greater than or equal to the first update interval, the first bone group is added to the animation execution list corresponding to the current frame picture, and the first counter value is zeroed. And in response to the first counter value being smaller than the first updating interval, accumulating the first counter value, wherein the first skeleton group does not join the animation execution list corresponding to the current frame picture.

The first counter is used for recording corresponding frame pictures when the first skeleton group carries out corresponding skeleton animation updating last time, and is distant from interval frames between current frame pictures.

Fig. 4 is a logic flow diagram for determining whether a bone animation update is performed on a current frame group according to an embodiment of the present application. As shown in fig. 4, each bone in the bone model of the first virtual object has a respective counter, for any bone in the bone model, the initial value of the counter is set to zero (S41), then, each frame of picture starts to calculate the bone for which the current frame needs to be subjected to the bone animation update (S42), firstly, the animation update interval corresponding to the bone in the current frame of picture is obtained based on the rendering size under the screen space corresponding to the current frame of picture and the configuration data table corresponding to the animation update interval, and the relationship between the current counter value of the bone and the animation update interval size is determined (S43). If the current counter value of the skeleton is less than the animation update interval, the counter value is incremented by 1 (S44), and it is determined that the skeleton is not being updated for the skeleton animation in the current frame (S45), and then the subsequent animation update logic is continued (S46). If the value of the counter is greater than the number of frames of the animation update interval, it is determined that the skeleton of the current frame is required to be updated (S47), and at the same time, the counter value corresponding to the skeleton is cleared (S48), and then the subsequent animation update logic is continued (S46).

In another possible implementation, the list of animation executions includes any one of the bone groups in the bone model in an initial state in response to the animation; and in response to the first counter value being smaller than the first updating interval, removing the first skeleton group from the animation execution list corresponding to the current frame picture, and determining the animation execution list corresponding to the current frame picture.

Wherein the first bone set is any one bone set in the bone model.

For example, the total number of bones included in the bone model of the first virtual object in the virtual scene is 127, with the terminal bone numbers of the hand, foot, and skirt portions being 84. When the bone animation LOD is enabled, after the animation update frequency of the end bone parts is reduced, 84 end bones are removed in the animation execution list, and only bones of the spine, the arms, the shoulders, the legs and the head remain in the animation execution list, and the number of the bones is 43.

In one possible implementation manner, acquiring a skeleton identifier corresponding to at least one skeleton group in an animation execution list; in the first scene picture, updating the skeleton animation of the skeleton group corresponding to the skeleton mark in the skeleton model in the current frame picture.

When the animation execution list is configured, the names of skeleton groups are added in the table, and in the process of updating the skeleton animation through the animation execution list, the skeleton names need to be converted into skeleton index values of the skeleton in the skeleton model. Therefore, it is necessary to convert the bone names in the animation execution list into index value lists of these bones and their sub-bones according to mapping information between each bone name in the bone model to the bone index value at the initialization stage and when the first virtual object changes the bone model.

That is, in the virtual scene operation process, the terminal determines the animation update interval corresponding to each skeleton group in the current picture based on the rendering size of the virtual object in the current screen space and the configuration data for determining the animation update interval corresponding to each skeleton group acquired from the server. When the rendering size of the virtual object in the screen space is large, that is, when the virtual object is included closer to the virtual camera or the actual model size of the virtual object is large, a small animation update interval can be maintained for each skeleton group of the virtual object in this case; when the rendering size of the virtual object in the screen space is smaller, namely the virtual object is far away from the virtual camera or the actual model size of the virtual object is smaller, for each skeleton group of the virtual object under the condition, the animation updating interval corresponding to the tail end skeleton group in the virtual object is preferentially increased, so that the problem that the performance of the game is influenced due to the fact that the skeleton animation is displayed is solved while the animation effect in the virtual scene is ensured.

Fig. 5 is a schematic diagram illustrating a corresponding skeletal animation update situation under different rendering sizes according to an embodiment of the present application. As shown in fig. 5, when the same virtual object performs the same hand-engaging action, the corresponding rendering sizes are different, and the animation update conditions corresponding to two adjacent frames of pictures of the skeleton of the finger part are also different. When the virtual object is located at a short distance from the virtual camera, the rendering size in the screen space is large, and when the virtual object is located at the first frame 511, the finger portion skeleton of the virtual object is in the expanded state 513, and when the virtual object is located at the second frame 512, the finger portion skeleton of the virtual object is in the slightly curved state 514. When the virtual object is located at a medium distance from the virtual camera, the rendering size in the screen space is slightly smaller than the rendering size at a short distance, the finger portion skeleton of the virtual object is in an expanded state 523 at a first frame 521 at a medium distance, and the finger portion skeleton of the virtual object is in a fully curved state 524 at a second frame 522 at a medium distance. When the virtual object is located at a long distance from the virtual camera, the rendering size in the screen space is small, and the finger portion skeleton of the virtual object is in the expanded state 533 in the long-distance first frame 531 and is still in the expanded state 534 in the long-distance second frame 532.

For example, the terminal may display a calculation process for determining a bone animation update based on the calculation instructions. As shown in table 2 below, the configuration data of the end skeleton group corresponding to the skeleton animation of the first virtual object.

TABLE 2

If the virtual camera is located right above the head of the terminal main control virtual object, that is, if the first scene is a scene displayed at the first view angle, if the distance between the main control virtual object and the virtual object of the enemy camp as the first virtual object in the virtual scene is far, the rendering size of the screen space corresponding to the virtual object of the enemy camp is smaller, and the rendering size is calculated to be 0.0014, and based on the data configured in table 2, the rendering size is smaller than the rendering size of the smallest screen space in the configuration data by 0.002, so that the frame number of the update interval of the skeleton animation of the current frame may be 180. In addition, when the value of the counter corresponding to the end skeleton is smaller than the skeleton animation updating interval frame number 180, the end skeleton does not participate in animation updating, and the number of the skeletons actually participating in updating is only 43 skeleton bones.

The relevant parameters in this process can be shown as ScreenSize (0.001419) TotalNumberOfBones (127) remannnumberofbones (43) updateRate (180) FrameCounter (12).

Wherein, the ScreenSize represents the rendering size in the screen space corresponding to the virtual object; totalNumberOfBones represents the total bone number in the bone model of the virtual object; the Remain NumberOfBones represents the number of bones participating in the updating of the bone animation in the current frame picture of the virtual object; updateRate represents the number of frames of the animation update interval of the end bones (e.g., hand, foot, and skirt bones) of the virtual object of the current frame; the FrameCounter indicates the value of the counter of the skeleton corresponding to the current frame picture.

As the value of the counter corresponding to the skeleton is incremented every frame, when the value of the counter exceeds 180, the number of skeletons participating in the update immediately becomes 127, and for this frame, the skeletons of the whole body of the virtual object participate in the animation update, and then the value of the counter immediately returns to zero to restart counting.

The relevant parameters of the process can be shown as ScreenSize (0.001413) TotalNumberOfBones (127) remalnnumberofbones (127) updateprate (180) FrameCounter (0).

When the main control virtual object gradually approaches to the virtual object of the enemy campaigns, the rendering size of the screen space of the virtual object of the enemy campaigns gradually increases, and when the rendering size of the screen space increases to 0.0024 (between 0.002 and 0.004 in the corresponding configuration data), the frame number of the updating interval of the skeleton animation of the character is reduced to 90, that is to say, the skeleton animation of the tail end skeleton of the first virtual object is updated every 90 frames at the moment.

The relevant parameters of the process can be shown as ScreenSize (0.002409) TotalNumberOfBones (127) remalnnumberofbones (43) updateRate (90) FrameCounter (35).

When the main control virtual object is closer to the first virtual object, the rendering size of the corresponding screen space is also increased continuously, the number of animation update interval frames corresponding to the skeleton animation is gradually reduced, and the update frequency of the tail end skeleton is gradually increased.

The relevant parameters of the process can be shown as ScreenSize (0.004804) TotalNumberOfBones (127) remalnnumberofbones (43) updateRate (30/5/0) FrameCounter (4).

Through the scheme shown in the embodiment, the multi-detail level of the skeletal animation can effectively reduce the time-consuming performance burrs of the terminal animation on the animation thread, and the following test can be performed.

On the same terminal equipment, the UE4 development building type is used for packaging, and when the main control virtual object and 20 other virtual objects are respectively used for fight under the two conditions of starting and not starting the skeleton animation LOD, the corresponding skeleton animation performance cost is tested. During the test, the master virtual object does not enable the skeletal animation LOD.

The specific test results are shown in table 3 below. As can be seen from the data in table 3, the average per frame overhead of the animation on the main thread is 3.36ms and the average per frame overhead on the asynchronous thread is 3.89ms without the skeletal animation LOD enabled. While in the case of enabling the skeletal animation LOD, the average overhead per frame of the animation on the main thread is 2.98ms, the time consumption is reduced by 11.3%, the average overhead per frame on the asynchronous thread is 2.46ms, and the time consumption is reduced by 36.8%.

TABLE 3 Table 3

Wherein, on the data with the maximum time consumption, the maximum time consumption of the animation on the main thread is found to be 8.68ms and the maximum time consumption on the asynchronous thread is found to be 21.12ms under the condition that the skeletal animation LOD is not enabled. While in the case of enabling the skeletal animation LOD, the maximum time consumption of the animation on the main thread is 10.66ms, the animation is improved by 18.6%, the maximum time consumption on the asynchronous thread is 10.88ms, and the animation is reduced by 48.5%. Fig. 6 is a schematic diagram of animation time consumption on an animation thread according to an embodiment of the present application, and as shown in fig. 6, by comparing an animation overhead schematic diagram 61 on a main thread and an asynchronous thread when a bone animation LOD is not formed with an animation overhead schematic diagram 62 on a main thread and an asynchronous thread when a bone animation LOD is opened, it can be found that the bone animation LOD can effectively reduce performance burrs of animation time consumption on the animation thread.
