The first terminal 110 may generally refer to one of a plurality of terminals, and the second terminal 130 may generally refer to another of the plurality of terminals, and this embodiment is only illustrated by the first terminal 110 and the second terminal 130. The device types of the first terminal 110 and the second terminal 130 are the same or different, and include: at least one of a smartphone, a tablet, an e-book reader, an MP3 player, an MP4 player, a laptop portable computer, and a desktop computer.

Only two terminals are shown in fig. 1, but there are a plurality of other terminals 140 that may access the server 120 in different embodiments. Optionally, one or more terminals 140 are terminals corresponding to the developer, a development and editing platform supporting a client in the virtual environment is installed on the terminal 140, the developer can edit and update the client on the terminal 140, and transmit the updated client installation package to the server 120 through a wired or wireless network, and the first terminal 110 and the second terminal 130 can download the client installation package from the server 120 to update the client.

The first terminal 110, the second terminal 130, and the other terminals 140 are connected to the server 120 through a wireless network or a wired network.

The server 120 includes at least one of a server, a plurality of servers, a cloud computing platform, and a virtualization center. The server 120 is used for providing background services for clients supporting a three-dimensional virtual environment. Optionally, the server 120 undertakes primary computational work and the terminals undertake secondary computational work; alternatively, the server 120 undertakes the secondary computing work and the terminal undertakes the primary computing work; alternatively, the server 120 and the terminal perform cooperative computing by using a distributed computing architecture.

The server 120 may employ synchronization techniques to make the visual appearance consistent among multiple clients. Illustratively, the synchronization techniques employed by the server 120 include: a state synchronization technique or a frame synchronization technique.

State synchronization techniques

In an alternative embodiment based on fig. 1, the server 120 employs a state synchronization technique to synchronize with multiple clients. In the state synchronization technique, as shown in fig. 2, the combat logic runs in the server 120. When a state change occurs to a virtual object in the virtual environment, the server 120 sends the state synchronization result to all clients, such as clients 1 to 10.

In an illustrative example, client 1 sends a request to server 120 requesting virtual object 1 to release the frost skill, and server 120 determines whether the frost skill allows release and what the damage value to other virtual objects 2 is when the release of the frost skill is allowed. The server 120 then sends the skill release results to all clients, which update the local data and interface performance according to the skill release results.

Frame synchronization technique

In an alternative embodiment based on fig. 1, the server 120 employs a frame synchronization technique to synchronize with multiple clients. In the frame synchronization technique, as shown in fig. 3, combat logic operates in each client. Each client sends a frame synchronization request to the server, where the frame synchronization request carries data changes local to the client. After receiving a frame synchronization request, the server 120 forwards the frame synchronization request to all clients. And after each client receives the frame synchronization request, processing the frame synchronization request according to local combat logic, and updating local data and interface expression.

With reference to the above description of the virtual environment and the description of the implementation environment, a method for displaying a virtual environment screen provided in the embodiment of the present application is described, and an execution subject of the method is exemplified by a client running on a terminal shown in fig. 1. The terminal runs with a client, which is an application that supports a virtual environment.

Referring collectively to fig. 4, during a virtual environment-based competition, a client is displayed with a user interface. An exemplary user interface includes: a virtual environment screen 22 and a HUD (Head Up Display) panel 24. The virtual environment screen 22 is a screen obtained by observing the virtual environment with the view angle corresponding to the virtual object 26. The HUD panel 24 includes a plurality of human-computer interaction controls, such as a movement control, three or four skill release controls, and an attack button.

Illustratively, there is a one-to-one correspondence of camera models for each virtual object in the virtual environment. The virtual object 26 in fig. 4 corresponds to a camera model 28. The center of view (or focus) of the camera model 28 is the virtual object 26, and the center of view is the intersection of the virtual environment and the centerline that the camera model 28 emits in the direction of view, also referred to as the focus of the camera model 28. The object located at the observation center is located at the center of the virtual environment picture in the virtual environment picture acquired by the camera model 28. As virtual object 26 moves within the virtual environment, the three-dimensional coordinates (also called anchor point location) of camera model 28 within the virtual environment also move following the movement of virtual object 26. The camera model 28 has a lens height relative to the virtual object 26. The camera model 28 looks down the virtual object 26 at an oblique angle (e.g., 45 degrees).

The image captured by the camera model 28 in the virtual environment is the virtual environment image 22 displayed on the client.

The embodiment of the present application provides a scheme for dynamically changing the anchor point of the camera model 28, so as to dynamically change the view of the virtual environment picture 22, which better meets the expectations of the user.

In the example shown in fig. 5, the terminal displays a user interface including a virtual environment screen and a human-computer interaction control superimposed on the virtual environment screen. The man-machine interaction control comprises: the view adjustment control 32, the movement direction control 34, the skill release control 36, and the attack control 38, as shown in fig. 5 (a). By default, the virtual environment view is a view that is captured by the camera model 28 in the virtual environment with the first position where the virtual object 26 is located as the center of view. When the user wishes to change the field of view, the field of view adjustment control 32 is pressed. The field of view adjustment control 32 changes from the smaller eye display modality to the larger wheel display modality, as shown in fig. 5 (b). In the wheel display configuration, the field of view adjustment control 32 includes a wheel region and a rocker located in the center of the wheel region. Wherein, the rocker corresponds the anchor point position of camera model 28, and the adjustable range of the anchor point position that the carousel region corresponds camera model 28. Illustratively, the adjustable range is a circular range.

Illustratively, as the user drags the joystick to change positions in the wheel region, the anchor point position of the camera model 28 in the virtual environment also changes. After changing the anchor point position, the center of view of the camera model 28 will switch from a first position in which the virtual object 26 is located to a second position that is offset with respect to the virtual object 26. The positional relationship of the second position with respect to the first position corresponds to the positional relationship of the rocker with respect to the center position of the wheel area, as shown in fig. 5 (c).

When the user's finger is released, the camera model 28 will capture a view in the virtual environment with the second position offset from the virtual object 26 as the center of view, as shown in fig. 5 (d). Since the position of the virtual environment 26 may change all the time, the second position, which is offset with respect to the virtual object 26, may also change all the time.

The operation of the whole process may include the following steps:

clicking a rocker:

and clicking a rocker on the visual field adjusting control by the user, and returning the anchor point position of the camera model to the default position when the finger of the user presses down. The default position is the anchor position when the first virtual object controlled by the user is at the center of the screen.

Dragging a rocker:

1. as the user drags the rocker on the view adjustment control, the anchor point position of the camera model may shift from the default position. After the user's finger is lifted, the anchor point position of the camera model stays at the last offset position.

2. What the user drags the rocker is changed is the relative position of the anchor point position of the camera model and the first virtual object, that is, the anchor point position of the camera model is bound with the first virtual object. When the first virtual object moves, the anchor point position of the camera model also moves.

Fig. 6 is a flowchart illustrating a method for displaying a virtual environment screen according to an exemplary embodiment of the present application. The embodiment is exemplified by applying the method to the client. The method comprises the following steps:

step 602, displaying a first virtual environment screen, wherein the first virtual environment screen is a screen obtained by observing a virtual environment with a first position relative to a first virtual object as an observation center;

the first virtual object is a virtual object controlled by a client, but the possibility is not excluded that the first virtual object is controlled by another client or an artificial intelligence module. The client controls the activity of the first virtual object in the virtual environment according to the received user operation (or the man-machine operation). Illustratively, the activity of the first virtual object in the virtual environment includes: at least one of walking, running, jumping, climbing, lying down, attacking, skill releasing, prop picking up, and message sending.

The first virtual environment screen is a screen obtained by observing the virtual environment with the first position relative to the first virtual object as the observation center by the camera model. Optionally, the camera model also has a certain lens height with respect to the first virtual object. The virtual environment picture is a two-dimensional picture which is displayed on the client after picture collection is carried out on the three-dimensional virtual environment. Illustratively, the shape of the virtual environment screen is determined according to the shape of a display screen of the terminal or according to the shape of a user interface of the client. Taking the display screen of the terminal as a rectangle as an example, the virtual environment picture is also displayed as a rectangle picture.

A camera model bound with the first virtual object is arranged in the virtual environment. The first virtual environment picture is a picture taken by the camera model with a certain observation position in the virtual environment as an observation center. The viewing center is a first position relative to the first virtual object when the first virtual environment picture is acquired. For example, the first location is where the first virtual object is located. Taking the first virtual environment picture as an example, the intersection point of the rectangular diagonal lines in the first virtual environment picture is the object located at the observation center.

In general, the camera model bound to the first virtual object takes the position of the first virtual object as an observation center, and the position of the first virtual object in the virtual environment is the first position. When the virtual environment is a three-dimensional virtual environment, the observation center is the three-dimensional coordinates of the first virtual object in the virtual environment. For example, if the ground in the virtual environment is a horizontal plane, and the height coordinate of the observation center is 0, the observation center may be approximately represented as a two-dimensional coordinate on the horizontal plane.

Step 604, adjusting the observation center from a first position relative to the first virtual object to a second position relative to the first virtual object in response to the adjustment instruction of the observation center;

the adjustment instruction is an instruction for adjusting the observation center. The adjustment instruction is triggered by the user, but does not exclude the possibility that the adjustment instruction is automatically triggered by Artificial Intelligence (AI) in the terminal, or sent by the server.

When the terminal is an electronic device with a touch screen, the adjustment instruction may be an instruction triggered by a touch operation on the touch screen; when the terminal is an electronic device with a handle peripheral, the adjusting instruction can be an instruction triggered on a handle physical key; when the terminal is a VR or AR, the adjustment instruction may be an instruction triggered by eyes or voice of the user, and the triggering manner of the adjustment instruction is not limited in the embodiment of the present application.

Illustratively, the first position is a position at which the first virtual object is located, or the first position is a position at which a first offset exists with respect to the position at which the first virtual object is located.

Illustratively, the second position is a position at which there is a second offset relative to the position at which the first virtual object is located. Typically, the first location and the second location are different.

Since the position of the first virtual object is dynamically changed, the second position relative to the first virtual object is also changed following the change in the position of the first virtual object.

Step 606, displaying a second virtual environment picture, wherein the second virtual environment picture is a picture obtained by observing the virtual environment by taking a second position relative to the first virtual object as an observation center;

since the first virtual environment screen and the second virtual environment screen have different observation centers, the first virtual environment screen and the second virtual environment screen have different visual fields.

As shown in fig. 7, in the first virtual environment picture, the picture center is a first position 72 relative to the first virtual object, and the first position 72 is a position where the first virtual object is located, where the first virtual object is located in the picture center; in the second virtual environment screen, the screen center is a second position 74 with respect to the first virtual object, and the second position 74 is a position that is offset to the first virtual object in the upper right direction, and at this time, the first virtual object is positioned at the lower left corner of the screen center, and the user has a larger field of view at the upper right of the first virtual object and a smaller field of view at the lower left.

In summary, in the method provided in this embodiment, the observation center is modified from the first position to the second position relative to the first virtual object in response to the adjustment instruction of the observation center, so that the user can customize the observation center of the camera model, thereby obtaining the optimal view field range meeting the user's own desire, and displaying more effective information in the virtual environment picture as much as possible.

The adjustment instruction may be triggered by a drag operation of the user on a view adjustment control displayed on the touch display screen.

Fig. 8 is a flowchart illustrating a method for displaying a virtual environment screen according to another exemplary embodiment of the present application. The method may be performed by a client as shown in fig. 1. The method comprises the following steps:

step 802, displaying a first user interface, where the first user interface includes a first virtual environment picture and a visual field adjustment control, and the first virtual environment picture is a picture obtained by observing a virtual environment with a first position relative to a first virtual object as an observation center;

the client displays a first user interface, the first user interface comprising: a first virtual environment frame 90 captured by the camera model, and a field of view adjustment control 32 superimposed on the first virtual environment frame.

A camera model bound with the first virtual object is arranged in the virtual environment. The first virtual environment picture is that the camera model takes the position of the first virtual object as an observation center, and the position of the first virtual object in the virtual environment is the first position.

Illustratively, when the virtual environment is a three-dimensional virtual environment, the observation center is the three-dimensional coordinates of the first virtual object in the virtual environment. For example, if the ground in the virtual environment is a horizontal plane, and the height coordinate of the observation center is 0, the observation center may be approximately represented as a two-dimensional coordinate on the horizontal plane.

Optionally, the field of view adjustment control 32 includes: a wheel area a and a rocker b. The wheel area a is a circular area and the rocker b is a circular button. The area of rocker b is smaller than the area of wheel area a. In a case where the drag operation by the user is not received, the jog dial b is displayed at the center of the jog dial area a. In case of receiving a drag operation by the user, the jog dial b may change its position within the circular area of the jog dial area a.

The rocker b corresponds to an observation center of the camera model (that is, an anchor point position of the camera model), the wheel disc area a corresponds to a default observation center of the camera model, for example, a position of the first virtual object, and a circular area range of the wheel disc area a corresponds to an adjustable range of the observation center of the camera model.

Step 804, responding to a dragging instruction triggered when the rocker is dragged in the wheel disc area, and adjusting the observation center from a first position relative to the first virtual object to a second position relative to the first virtual object according to the position of the dragged rocker in the wheel disc area;

since the wheel area a corresponds to the default observation center of the camera model, the circular area range of the wheel area a corresponds to the adjustable range of the observation center of the camera model. Therefore, after receiving the dragging operation of the user, the client adjusts the observation center from the first position relative to the first virtual object to the second position relative to the first virtual object according to the position of the dragged rocker in the wheel area in response to the dragging instruction triggered when the rocker is dragged in the wheel area. Specifically, the method includes the following steps S1 to S5, as shown in fig. 9:

s1, responding to a dragging instruction triggered when the rocker is dragged in the wheel disc area, and calculating a wheel disc transverse offset value and a wheel disc longitudinal offset value of the position of the dragged rocker in the wheel disc area relative to the center position of the wheel disc area;

referring to fig. 10, assuming that the position of the dragged rocker in the wheel area is P2 and the center position of the wheel area is P1, the lateral offset value of the wheel is (P2-P1) the projection length in the horizontal direction (P2-P1). x, and the longitudinal offset value of the wheel is (P2-P1) the projection length in the vertical direction (P2-P1). z.

The wheel lateral offset value and the wheel longitudinal offset value are two-dimensional offsets on the UI layer, and the camera model is in a three-dimensional virtual environment, and the two-dimensional offsets need to be mapped into three-dimensional offsets.

Referring to fig. 10, an x-axis, a y-axis, and a z-axis are provided in the three-dimensional virtual environment. Wherein the y-axis corresponds to the lens height of the camera model. In this embodiment, the horizontal offset value of the wheel disc is set to correspond to the offset value of the camera model on the x axis, and the vertical offset value of the wheel disc is set to correspond to the offset value of the camera model on the z axis, both of which do not affect the position of the camera model on the y axis. That is, the lens height of the camera model is a fixed value or is otherwise adjusted, but is not related to the adjustment logic in this embodiment.

S2, determining a first camera offset value according to the wheel disc transverse offset value and determining a second camera offset value according to the wheel disc longitudinal offset value;

the first camera offset value is an offset value of the camera model in the x-axis and the second camera offset value is an offset value of the camera model in the z-axis. The X-axis and the z-axis are two coordinate axes parallel to the ground plane in the virtual environment, and the X-axis is perpendicular to the z-axis.

Optionally, the wheel lateral offset distance and the first camera offset value are in a positive correlation; the wheel longitudinal offset distance and the second camera offset value are in a positive correlation. For example, the wheel lateral offset distance is directly proportional to the first camera offset value; the wheel longitudinal offset distance and the second camera offset value are in a directly proportional relationship.

S3, calculating a first anchor point position of the camera model corresponding to the first virtual object based on the position of the first virtual object in the virtual environment;

the first anchor point position moves following the movement of the position of the first virtual object.

Optionally, the first anchor point location is a three-dimensional coordinate of the camera model in the virtual environment when the observation center of the camera model is the first virtual object.

S4, offsetting the first anchor point position according to the first camera offset value and the second camera offset value, and calculating to obtain a second anchor point position of the camera model;

and offsetting the first anchor point position on the x axis according to the first camera offset value, offsetting the first anchor point position on the z axis according to the second camera offset value, and calculating to obtain a second anchor point position of the camera model.

And S5, offsetting the camera model according to the second anchor point position, wherein the observation center of the offset camera model is the second position relative to the first virtual object.

And S6, responding to the position change of the first virtual object in the virtual environment, executing the steps of offsetting the first anchor point position according to the first camera offset value and the second camera offset value, and calculating to obtain a second anchor point position of the camera model.

Since the first virtual object can move in the three-dimensional virtual environment, when the position of the first virtual object in the three-dimensional virtual environment changes, the client performs the step of calculating the second position relative to the first virtual object according to the offset direction and the second offset distance by taking the position of the first virtual object in the virtual environment as a reference again.

The centre of view of the camera model (relative to the second position of the first virtual object) will still dynamically change following the position of the first virtual object.

Before the adjustment is finished to the next adjustment (manual or automatic adjustment for opening), the observation center of the camera model is kept at the second position, that is, the camera model continuously performs image acquisition by taking the second position relative to the first virtual object as the observation center.

806, displaying a second user interface, where the second user interface includes a second virtual environment picture and a view field adjustment control, and the second virtual environment picture is a picture obtained by observing the virtual environment with a second position relative to the first virtual object as an observation center;

and after the observation center is adjusted to be the second position, observing the virtual environment by using the camera model relative to the second position of the first virtual object as the observation center to obtain a second virtual environment picture. The client also superimposes and displays the visual field adjusting control on the second virtual environment picture, so that a second user interface is displayed.

Optionally, if the view adjustment control is opaque, the blocked area in the second virtual environment picture does not need to be displayed; and if the visual field adjusting control is transparent or semitransparent, overlapping the shielded area in the second virtual environment picture and the visual field adjusting control into a fused image for displaying.

In summary, in the method provided in this embodiment, the wheel disc offset information of the rocker on the two-dimensional plane is used to calculate the offset information of the camera model in the three-dimensional environment, so that the rocker change of the view field adjustment control and the three-dimensional offset of the camera model are in a positive correlation, and the "what you see is what you get" operation effect is achieved.

In an alternative embodiment based on fig. 8, the drag instruction comprises: at least two sub-instructions ordered in time. Typical drag instructions include: the touch control method comprises a touch start sub-instruction, a plurality of touch moving sub-instructions and a touch end sub-instruction which are sequenced according to time, wherein each sub-instruction carries real-time touch coordinates of a user on a touch screen. The touch start sub-instruction can be regarded as a first sub-instruction, and the touch end sub-instruction can be regarded as a last sub-instruction. As illustrated in fig. 11, the method further comprises:

step 803a, in response to receiving a first sub-instruction in the dragging instruction, switching the view field adjustment control from a default display mode to a wheel disc display mode, wherein the wheel disc display mode comprises a rocker and a wheel disc area;

and the display area of the default display form is smaller than that of the wheel disc display form.

Optionally, the default display modality is a smaller eye button. The smaller eye button does not obscure too much of the screen content on the second virtual environment screen.

Step 805, in response to receiving the last sub-instruction in the dragging instruction, the view adjustment control is switched from the wheel disc display form to the default display form.

In summary, the method provided in this embodiment provides two display forms for the visual field adjustment control, and the visual field adjustment control in the default display form has a smaller display area, so that the influence on the screen content in the virtual environment screen can be reduced.

In an alternative embodiment based on fig. 8, since the user may adjust the center of view of the camera model multiple times during a session, in order to ensure operational consistency during each adjustment. As shown in fig. 12, the method further includes:

in response to receiving the first sub-instruction in the drag instruction, the observation center is reset to the position of the first virtual object in the virtual environment, step 803 b.

And when the client receives the dragging operation on the visual field adjusting control, triggering a dragging instruction on the visual field adjusting control. The drag instruction includes: the touch control method comprises a touch start sub-instruction, a plurality of touch moving sub-instructions and a touch end sub-instruction which are sequenced according to time, wherein each sub-instruction carries real-time touch coordinates of a user on a touch screen.

In response to receiving the touch start sub-instruction, the client resets the observation center to a position in the virtual environment where the first virtual object is located. That is, the client resets the coordinates of the camera model in the virtual environment to the first anchor point position.

In summary, according to the method provided in this embodiment, when the dragging instruction on the view field adjustment control starts to be received, the observation center is reset to the position where the first virtual object is located in the virtual environment, so that the user can obtain consistent operation feeling when adjusting the observation center each time, and thus the observation center is quickly and accurately adjusted to the desired position of the user.

In an alternative embodiment, there is an upper limit to the adjustment range of the center of view of the camera model.

As shown in fig. 13, the client sets the maximum offset values of the observation center of the camera model in four directions, i.e., up, down, left, and right: UP, DOWN, LEFT, RIGHT. UP is the maximum offset value in the UP direction, DOWN is the maximum offset value in the DOWN direction, LEFT is the maximum offset value in the LEFT direction, and RIGHT is the maximum offset value in the RIGHT direction.

When the field of vision adjustment controlling part adopts the rim plate controlling part to realize, the rim plate controlling part includes: a wheel area and a rocker located on the wheel area. The position of the rocker on the region of the wheel (offset position with respect to the center of the wheel) corresponds to the center of view of the camera model (offset position with respect to the first virtual object). The circular area range of the wheel disc area corresponds to the maximum adjustable range of the observation center. Each position on the roulette region "one-to-one" corresponds to the maximum adjustable range of the viewing center in the virtual environment.

In an alternative embodiment, the anchor point position of the camera model is calculated as follows:

as shown in fig. 14, an included angle between the rocker and the horizontal direction is set to be α, a distance between the rocker and the circle in the wheel disc region is set to be a, and a radius of the circle in the wheel disc region is set to be B. If the rocker is deviated to the upper left corner, the anchor point position of the camera model is deviated from the default anchor point position to the upper left corner according to the same angle.

LEFT offset of camera model cos α LEFT (a/B);

the upward offset of the camera model is sin α UP (a/B).

In an alternative embodiment, the following three variables are first defined:

CameraOffset: to measure the offset value of the center of view of the camera model relative to the first virtual object. The control module of the camera model reads the value and adds the offset value to the logic of the camera model following the first virtual object, so that the function of offsetting the observation center of the camera model is achieved.

IsMoved: is used for distinguishing whether the operation of the user on the rocker is click operation or drag operation. When the user presses the rocker button, it is set to no (false); when the dragging distance of the user to the rocker exceeds the dead zone area, the drag distance is set to true.

DeadZone (dead zone): configured by the plan, a threshold value of a drag distance for distinguishing whether a touch operation on the jog dial is a click operation or a drag operation in the roulette region is schematically shown in fig. 15, and an edge of a dead zone is shown by a dotted circle 40.

As shown in fig. 16, the method for displaying the virtual environment screen includes the following steps:

step 1601, pressing a rocker of the visual field adjusting control;

and pressing a rocker of the visual field adjusting control by the user, and triggering and generating a touch starting event on the touch screen. The touch start sub-event carries the two-dimensional coordinates of the location of the user's press on the touch screen.

Step 1602, resetting the offset value of the camera model to zero;

the client resets the offset value CameraOffset of the camera model to zero. This clears the offset value of the previous camera model.

Step 1603, IsMoved ═ false;

and the client sets the value of IsMoved to false.

Step 1604, dragging a rocker of the visual field adjusting control;

the user drags a rocker of the visual field adjusting control, and continuously triggers (according to the reporting frequency of touch) a touch moving event on the touch screen. Each touch movement event carries two-dimensional coordinates of the user's touch location on the touch screen.

Step 1605, assigning the position of the dragged rocker to be P2;

and the client assigns the two-dimensional coordinate of the dragged rocker on the touch screen to P2.

Step 1606, determining whether | P2-P1| is greater than or equal to the dead zone radius, and IsMoved ═ true;

p1 is the two-dimensional coordinate of the touch screen where the center point of the wheel area is located.

In the process of dragging the rocker by the user, the client judges whether the displacement | P2-P1| of the position of the dragged rocker relative to the central point of the wheel area reaches the dead zone threshold value. I.e. | P2-P1| is ≧ deadZone.

If the dragging distance reaches the dead zone threshold, executing step 1607; if the drag distance does not reach the dead zone threshold, the IsMoved value is maintained.

Step 1607, IsMoved ═ true;

and the client sets the value of IsMoved to true.

Step 1608, calculate offset values for the camera model with vectors (P2-P1).

Firstly, a client reads five preset values:

LEFT: a maximum offset value in the left direction;

RIGHT: maximum offset value in right direction;

DOWN: maximum offset value in the down direction;

UP: maximum offset value in the up direction;

MAX _ RADIUS: maximum drag distance of the rocker in the area of the wheel.

Because at the User Interface (UI) level is a two-dimensional plane, (P2-P1) is a two-dimensional vector, and the anchor point location of the camera model is in a three-dimensional scene, the offset vector of the camera model is a three-dimensional vector. Assuming that the lens height of the camera model is kept constant, it is necessary to fix the y-coordinate offset component (coordinate component corresponding to the lens height) in the anchor point position of the camera model by 0, and then calculate the lens offset by the following steps:

1. the length of the calculation (P2-P1) is length,

2. the formula for calculating the offset value, camera offset.x, of the camera model in the x-axis (horizontal direction) is as follows

If (p2-p1). x >0, indicating a rightward shift;

cameraOffset.x＝(p2-p1).x/MAX_RADIUS*RIGHT；

other cases, indicating a leftward shift;

cameraOffset.x＝(p2-p1).x/MAX_RADIUS*LEFT。

3. the formula for calculating the offset value of the camera model in the z-axis (horizontal direction) cameraoffset.z is as follows:

if (p2-p1). z >0, indicating an upward shift;

cameraOffset.z＝(p2-p1).y/MAX_RADIUS*UP；

other cases, indicating a leftward shift;

cameraOffset.z＝(p2-p1).y/MAX_RADIUS*DOWN。

referring to fig. 16 in combination, it can be seen that the client generally configures a height for the height distance between the first virtual object operator and the camera model, and configures an inclination angle angel for the downward viewing angle of the camera model. The client then calculates the default anchor point position of the camera model from the current position of the first virtual object. Since the setting of the game, the x-axis of the camera relative to the first virtual character does not change, only the y-axis and the z-axis need to change, the calculation formula of the camera model in the virtual environment (following the first virtual object) is as follows:

cameraPos.x＝ActorPos.x；

cameraPos.y＝ActorPos.y+height*cos(angle)；

camearPos.z＝ActorPos.z–height*san(angle)；

after the default anchor point position cameraPos of the camera model is calculated, the final anchor point position of the camera model is obtained by adding the calculated offset value (cameraoffset.x, cameraoffset.z) to the cameraPos, and the lens offset effect on the camera model is also achieved.

cameraPos＝cameraPos+cameraOffset。

The arrangement of the x-axis, the y-axis and the z-axis in the three-dimensional virtual environment is shown in fig. 4.
