[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. At the same time, in the description of the embodiments of the present application, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] Embodiments of the present application provide an animation generation method, device, electronic device, and computer-readable storage medium.

[0030] Specifically, this embodiment will be described from the perspective of an animation generation device. The animation generation device can be integrated into an electronic device. That is, the animation generation method of the embodiment of the present application can be performed by an electronic device. Optionally, the electronic device can include a terminal device. The terminal device can be a mobile phone, tablet computer, smart Bluetooth device, laptop computer, game console, or personal computer (PC).

[0031] The animation generation method provided in the embodiments of the present application can be applied, for example, to an animation generation system. The animation generation system may include a player terminal device and a server. The terminal device may include both receiving and transmitting hardware, i.e., a device having receiving and transmitting hardware capable of performing bidirectional communication over a bidirectional communication link. The player terminal device and the server may communicate bidirectionally via a network.

[0032] Optionally, the server may be a standalone server, or a server network or server cluster consisting of servers, including but not limited to a computer, a network host, a single network server, a set of multiple network servers, or a cloud server consisting of multiple servers. A cloud server is composed of a large number of computers or network servers based on cloud computing.

[0033] The following is a detailed description of each step in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments. Although the flowcharts illustrate a logical order, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0034] The animation generation method of this embodiment obtains the object gaze points corresponding to the first virtual object and the second virtual object in the virtual scene, respectively, where the object gaze points are the gaze points of the virtual camera when shooting the virtual objects; determines the first camera shooting parameters when the virtual camera shoots the corresponding virtual objects; based on the object gaze points and the first camera shooting parameters, determines the second camera shooting parameters of multiple animation frames to be shot by the virtual camera during the transition shooting process, where the transition shooting is the transition from shooting the first virtual object to shooting the second virtual object; based on the second camera shooting parameters, controls the virtual camera to shoot multiple animation frames in the virtual scene to obtain an object transition animation, which can make the animation presentation effect of the transition shooting between the two virtual objects more natural and enhance the player's visual experience.

[0035] Please refer to Figure 1 Taking a terminal as an example, this embodiment provides an animation generation method. The specific process of the animation generation method can be as follows: Step 101 to Step 104, wherein:

[0036] Step 101: Obtain object gaze points corresponding to a first virtual object and a second virtual object in a virtual scene, respectively. The object gaze points are gaze points when a virtual camera is photographing the virtual objects.

[0037] It is understandable that in order to enable the terminal to understand the position that the virtual camera focuses on when shooting the first virtual object and the second virtual object, the terminal can introduce an object gaze point, which can be the gaze point of the virtual camera when shooting the virtual object, that is, it indicates the position that the virtual camera focuses on when shooting the virtual object, so that when the virtual camera transfers the virtual object being shot, it can perform shooting transfer based on the position that the virtual camera focuses on when shooting different virtual objects, so as to ensure that the transition of the picture shot by the virtual camera during the shooting transfer process is more natural, thereby ensuring the player's visual experience.

[0038] For example, Figure 2 As shown, Figure 2 The virtual scene shown includes at least two virtual characters, character A and character B. Camera A is used to film character A, and the subject's gaze point when camera A films character A is point A. Camera B is used to film character B, and the subject's gaze point when camera B films character B is point B. For ease of description, in this example, camera A and camera B are used to film characters A and B, respectively. In actual applications, camera A and camera B can be the same virtual camera.

[0039] It should be noted that the above-mentioned virtual scene is a virtual scene displayed (or provided) when the application is running on a terminal or server. Optionally, the virtual scene can be a simulation environment of the real world, or a semi-simulation and semi-fictitious virtual environment, or a purely fictitious virtual environment. The virtual scene can be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene or a three-dimensional virtual scene. The embodiment of the present application does not limit the dimension of the virtual scene. For example, the virtual scene may include the sky, land, ocean, etc., and the land may include environmental elements such as deserts and cities, and the user can control the virtual object to move in the virtual scene.

[0040] It should be noted that the first virtual object and the second virtual object are both virtual objects, and the above-mentioned virtual objects refer to dynamic objects or static objects in the virtual scene. The virtual object can be an object that can be controlled by the user or an object that cannot be controlled by the user. Optionally, the virtual object can be a virtual character, a virtual animal, an animated character, etc. The virtual object can be a virtual image in the virtual scene that is used to represent the user. The virtual scene can include at least one virtual object, and each virtual object has its own shape and volume in the virtual scene, occupying a part of the space in the virtual scene. In one possible implementation, the user can control the virtual object to move in the virtual scene, for example, control the virtual object to run, jump, crawl, etc., and can also control the virtual object to use the skills, virtual props, etc. provided by the application to fight with other game characters.

[0041] In some embodiments, a specific interaction behavior may be performed between the first virtual object and the second virtual object, but no specific interaction behavior may be performed between the first virtual object and the second virtual object.

[0042] In some embodiments, the first virtual object and the second virtual object may both be virtual objects controlled by the current device; or, the first virtual object and the second virtual object may also be virtual objects controlled by different terminals, for example, the first virtual object is a virtual object controlled by the current device, and the second virtual object is a virtual object controlled by other terminal devices.

[0043] The current terminal is a terminal controlled by the current user through the game account, which means that the first virtual object is a virtual object controlled by the current user.

[0044] Among them, the other terminals can be terminals controlled by other users through user accounts, which means that the second virtual object refers to a virtual object controlled by other users. Alternatively, the other terminals can also be game servers, which means that the second virtual object is an NPC character provided by the game server. The specific settings can be made according to needs and are not limited here.

[0045] In some embodiments, the above-mentioned obtaining of the object gaze points corresponding to the first virtual object and the second virtual object in the virtual scene may include: obtaining the initial camera position, camera orientation and initial camera arm length when the above-mentioned virtual camera shoots the above-mentioned first virtual object or the above-mentioned second virtual object respectively; determining the object gaze point corresponding to the above-mentioned first virtual object based on the initial camera position, camera orientation and initial camera arm length corresponding to the above-mentioned first virtual object; determining the object gaze point corresponding to the above-mentioned second virtual object based on the initial camera position, camera orientation and initial camera arm length corresponding to the above-mentioned second virtual object.

[0046] For example, based on Figure 2 In the example shown, the terminal can determine the position of camera A in the virtual scene as the initial camera position corresponding to character A, the orientation between camera A and point A as the camera orientation corresponding to character A, and the distance between camera A and point A as the initial camera arm length corresponding to character A.

[0047] In addition, the terminal can also determine the position of camera B in the virtual scene as the initial camera position corresponding to character B, the orientation between camera B and point B as the camera orientation corresponding to character B, and the distance between camera B and point B as the initial camera arm length corresponding to character B.

[0048] Specifically, the above-mentioned determination of the object gaze point corresponding to the first virtual object based on the initial camera position, camera orientation and initial camera arm length corresponding to the first virtual object may include: determining a first direction vector of the virtual camera toward the object gaze point corresponding to the first virtual object based on the camera orientation corresponding to the first virtual object; determining a first relative position vector between the virtual camera and the object gaze point corresponding to the first virtual object based on the first direction vector and the initial camera arm length corresponding to the first virtual object; determining the object gaze point corresponding to the first virtual object based on the initial camera position corresponding to the first virtual object and the first relative position vector.

[0049] Specifically, the above-mentioned determination of the object gaze point corresponding to the second virtual object based on the initial camera position, camera orientation and initial camera arm length corresponding to the second virtual object may include: determining a second direction vector of the virtual camera toward the object gaze point corresponding to the second virtual object based on the camera orientation corresponding to the second virtual object; determining a second relative position vector between the virtual camera and the object gaze point corresponding to the second virtual object based on the second direction vector and the initial camera arm length corresponding to the second virtual object; and determining the object gaze point corresponding to the second virtual object based on the initial camera position corresponding to the second virtual object and the second relative position vector.

[0050] For example, set the initial camera position camera_location, the direction vector corresponding to the camera orientation to addition_yaw_diretion, the initial camera arm length arm_length, and the object focus point focus_location, that is, focus_location = camera_location - addition_yaw_diretion * arm_length.

[0051] Step 102: Determine first camera shooting parameters when the virtual camera shoots the corresponding virtual object.

[0052] Among them, the above-mentioned first camera shooting parameters are used to indicate the parameters of the virtual camera when shooting the corresponding virtual object in the virtual scene, that is, one first camera shooting parameter is the parameter of the virtual camera when shooting the first virtual object in the virtual scene, and another first camera shooting parameter is the parameter of the virtual camera when shooting the second virtual object in the virtual scene.

[0053] It can be understood that the shooting parameters of the first camera when shooting the first virtual object can be exactly the same as the shooting parameters of the first camera when shooting the second virtual object, or can be completely different, or can be at least partially different. The specific parameters can be determined based on the user's requirements for the scene effect of the corresponding virtual scene, and are not limited here.

[0054] Specifically, the above-mentioned first camera shooting parameters may include camera pose indication parameters to determine the camera pose of the virtual camera based on the camera pose indication parameters. Alternatively, the above-mentioned shooting parameters may also directly include the camera pose of the virtual camera to directly use the camera pose of the virtual camera to control the virtual camera.

[0055] The camera position indication parameters may include but are not limited to the camera rotation angle and the camera arm length.

[0056] The camera rotation angle is used to indicate the shooting posture of the virtual camera when shooting the corresponding virtual object. The camera rotation angle can be an Euler angle, including but not limited to yaw angle, pitch angle, roll angle, etc., and can be set according to needs and is not limited here. For example, the value range of the camera rotation angle can be -180° to 180°, or 0° to 360°.

[0057] Among them, the above-mentioned yaw angle refers to the angle of rotation of the camera around the vertical axis (usually the upward direction of the camera itself), which describes the direction of the camera's left and right rotation; the above-mentioned pitch angle refers to the angle of rotation of the camera around the horizontal axis (usually the left and right direction of the camera), which describes the direction of the camera looking up or down; the above-mentioned roll angle refers to the angle of rotation of the camera around the front-to-back axis (usually the direction of the camera lens), which determines the horizontal tilt of the camera.

[0058] The camera arm length is used to indicate the distance between the virtual camera and the camera gaze point, and the value range of the camera arm length can be a positive rational number.

[0059] Specifically, the above-mentioned determination of the first camera shooting parameters when the virtual camera shoots the corresponding virtual object may include: obtaining a first camera position of the virtual camera when shooting the first virtual object, calculating a first difference based on the first camera position and the object gaze point corresponding to the first virtual object, and using the first difference as the camera arm length corresponding to the first virtual object; and / or, obtaining a second camera position of the virtual camera when shooting the second virtual object, calculating a second difference based on the second camera position and the object gaze point corresponding to the second virtual object, and using the second difference as the camera arm length corresponding to the second virtual object.

[0060] Step 103: Based on the object gaze point and the first camera shooting parameters, determine the second camera shooting parameters of the multiple animation frames to be shot by the virtual camera during the transition shooting process, where the transition shooting is transitioning from shooting for the first virtual object to shooting for the second virtual object.

[0061] It can be understood that by determining the second camera shooting parameters corresponding to different animation frames during the transition shooting process based on the object gaze point and the first camera shooting parameters, it is possible to avoid directly moving the virtual camera in a straight line from the position of shooting the first virtual object to the position of shooting the second virtual object, which would result in a stiff animation effect of the transition shooting between the two virtual objects, and to avoid the situation where the virtual camera passes through the virtual objects when the two virtual objects are face to face or nearly face to face, thereby improving the player's visual experience and avoiding visual discomfort to the player.

[0062] In some embodiments, the second camera shooting parameters include the target viewpoint and camera parameters of the above-mentioned virtual camera. The above-mentioned second camera shooting parameters of the multiple frames of animation frames to be shot by the above-mentioned virtual camera during the transition shooting process based on the above-mentioned object gaze point and the above-mentioned first camera shooting parameters may include: determining the transition process indication parameters of each animation frame; interpolating the above-mentioned object gaze point based on the above-mentioned transition process indication parameters of each animation frame to obtain the target viewpoint corresponding to each animation frame; interpolating the above-mentioned first camera shooting parameters based on the above-mentioned transition process indication parameters of each animation frame to obtain the camera parameters corresponding to each animation frame.

[0063] In this embodiment, by determining the target viewpoints corresponding to the multiple animation frames of the virtual camera during the transition process, the situation in which the animation of the virtual object during the transition process is shot and rendered stiffly is avoided.

[0064] The transition progress indicator parameter is used to indicate the relative progress of the corresponding animation frame during the transition shooting process.

[0065] In this embodiment, since the transition process indication parameter refers to the relative situation between the above-mentioned object gaze points or the above-mentioned first camera shooting parameters, based on the transition process indication parameter, the target viewpoint and camera parameters corresponding to each animation frame can be determined from the corresponding range composed of the object gaze points or the first camera shooting parameters corresponding to the first virtual object and the second virtual object respectively.

[0066] Specifically, the transition progress indication parameter may include a preset ratio coefficient, and the preset ratio coefficient is used to indicate the relative progress of the animation frame during the transition shooting process.

[0067] For example, Figure 3 As shown, in Figure 3 The transition progress indicator parameter may be 10%, to indicate that the content captured by the animation frame is the content when the transition capture process reaches 10%, such as Figure 4 As shown, in Figure 4 The transition progress indicator parameter may be 50%, indicating that the content captured by the animation frame is the content when the transition capture process reaches 50%, such as Figure 5 As shown, in Figure 5 The transition process indication parameter can be 90%, indicating that the content captured by the animation frame is the content when the transition shooting process reaches 90%. For example, the transition process indication parameter can be 100%, indicating that the content captured by the animation frame is the content when the transition shooting process ends, that is, the content when the virtual camera shoots the second virtual object.

[0068] Specifically, the above-mentioned transition process indication parameter may include a value in a parameter value range, and the parameter value range is composed of at least two critical values, each critical value corresponds to an object gaze point or a first camera shooting parameter, that is, the parameter value range matches the position range corresponding to the object gaze point or the parameter range corresponding to the first camera shooting parameter, and the two have a mapping relationship.

[0069] Among them, the above-mentioned target viewpoint is the camera gaze point of the virtual camera, which indicates the position that the virtual camera focuses on when shooting the virtual scene, so as to indicate the content that the virtual camera currently needs to shoot based on the camera gaze point, that is, the content that needs to be presented in the animation frame to be shot.

[0070] It can be understood that since the above-mentioned target viewpoint is determined based on the object gaze point of the first virtual object and the second virtual object, the shooting transition situation can be indicated by the change of the target viewpoint, that is, in the process of transitioning from shooting for the first virtual object to shooting for the second virtual object, the target viewpoint can be used to indicate the picture that needs to be paid attention to in the transition process, that is, the closer the target viewpoint is to the object gaze point corresponding to the second virtual object, the greater the degree of attention to the second virtual object, and thus the proportion of the second virtual object in the captured animation frame will be greater.

[0071] For example, Figures 3 to 5 As shown, Figures 3 to 5 The virtual scene shown includes two object gaze points, namely point A and point B, and a target viewpoint is set between point A and point B. Figure 3 In the virtual scene shown, when the transition shooting process reaches 10%, the target viewpoint is close to point A, indicating that the current focus on character A is greater, that is, the virtual camera begins to transition to character B. Figure 4 In the virtual scene shown, when the transition shooting process reaches 50%, the target viewpoint is at the center of point A and point B, indicating that the current attention to character A and character B is balanced, that is, the transition shooting process of the virtual camera is centered. Figure 5 In the virtual scene shown, when the transition shooting process reaches 90%, the target viewpoint is close to point B, indicating that the current focus on character B is relatively large, that is, the virtual camera is about to completely shoot character B.

[0072] Specifically, the above-mentioned object gaze point is interpolated based on the above-mentioned transition process indication parameters of each animation frame to obtain the target viewpoint corresponding to each animation frame, including: based on the above-mentioned transition process indication parameters of each animation frame, taking values within the position range corresponding to the above-mentioned object gaze point to obtain the target viewpoint corresponding to each animation frame.

[0073] Exemplarily, based on the above-mentioned transition process indication parameter of an animation frame, taking values within the position range corresponding to the above-mentioned object gaze point to obtain a target viewpoint corresponding to an animation frame can include: determining a position difference vector between at least two object gaze points; determining the product between the position difference vector and the transition process indication parameter; and determining the target viewpoint corresponding to an animation frame based on the object gaze point and the product.

[0074] For example, based on Figure 2 In the example shown, if the position of point A is set to location_a and the position of point B is set to location_b, the position difference vector diretion can be obtained by calculating the difference between location_a and location_b.

[0075] Then, by setting the transition process indication parameter to focus_point, the position of the target viewpoint focus_location can be calculated, that is, focus_location=location_a+diretion*focus_point.

[0076] In some embodiments, the camera parameters in the second camera shooting parameters are used to indicate parameters of the virtual camera when shooting the virtual scene during the transition shooting process.

[0077] It is understandable that, since the camera parameters corresponding to the multiple animation frames are obtained based on the first camera shooting parameters corresponding to the first virtual object and the second virtual object, the camera parameters corresponding to the multiple animation frames are not the same.

[0078] Specifically, the above-mentioned camera parameters may include camera pose indication parameters to determine the camera pose of the virtual camera based on the camera pose indication parameters, or the above-mentioned shooting parameters may directly include the camera pose of the virtual camera to directly use the camera pose of the virtual camera to control the virtual camera.

[0079] The camera position indication parameters may include but are not limited to the camera rotation angle and the camera arm length.

[0080] The camera rotation angle is used to indicate the shooting posture of the virtual camera when shooting the virtual scene during the transition shooting process. The camera rotation angle can be an Euler angle, including but not limited to yaw angle, pitch angle, roll angle, etc., and can be set according to needs and is not limited here. For example, the value range of the camera rotation angle can be -180° to 180°, or 0° to 360°.

[0081] Among them, the above-mentioned yaw angle refers to the angle of rotation of the camera around the vertical axis (usually the upward direction of the camera itself), which describes the direction of the camera's left and right rotation; the above-mentioned pitch angle refers to the angle of rotation of the camera around the horizontal axis (usually the left and right direction of the camera), which describes the direction of the camera looking up or down; the above-mentioned roll angle refers to the angle of rotation of the camera around the front-to-back axis (usually the direction of the camera lens), which determines the horizontal tilt of the camera.

[0082] The camera arm length is used to indicate the distance between the virtual camera and the target viewpoint, and the value range of the camera arm length can be a positive rational number.

[0083] In some embodiments, the above-mentioned camera posture indication parameters include the camera arm length, and the above-mentioned transition process indication parameters based on each animation frame interpolate the above-mentioned first camera shooting parameters to obtain the camera parameters corresponding to each animation frame, which may include: based on the above-mentioned transition process indication parameters of each animation frame, interpolating the arm length value range corresponding to the above-mentioned first camera shooting parameters to obtain the camera arm length corresponding to each animation frame.

[0084] For example, if the camera arm length in the first camera shooting parameter corresponding to the first virtual object is 50m, and the camera arm length in the first camera shooting parameter corresponding to the second virtual object is 100m, then the arm length corresponding to the above first camera shooting parameter has a value range of 50m to 100m.

[0085] It can be understood that since the camera arm length corresponding to each animation frame is determined based on the arm length value range corresponding to the first camera shooting parameter, the shooting transition can be indicated by the change in the camera arm length, that is, in the process of transitioning from shooting for the first virtual object to shooting for the second virtual object, the closer the virtual camera is to the second virtual object, the closer the camera arm length corresponding to the animation frame is to the camera arm length corresponding to the second virtual object, thereby making the shooting transition in the captured animation frame more natural.

[0086] For example, Figures 3 to 5 As shown, in Figure 3 In the virtual scene shown, when the transition shooting process reaches 10%, the camera arm length corresponding to the animation frame is close to the camera arm length corresponding to character A, indicating that the virtual camera begins to transition shooting towards character B. Figure 4 In the virtual scene shown, when the transition shooting process reaches 50%, the camera arm length corresponding to the animation frame is the median between the camera arm length corresponding to character A and the camera arm length corresponding to character B. Figure 5 In the virtual scene shown, when the transition shooting process reaches 90%, the camera arm length corresponding to the animation frame is close to the camera arm length corresponding to character B, that is, the virtual camera is about to shoot character B completely.

[0087] In some embodiments, the above-mentioned camera posture indication parameters include the camera rotation angle, and the above-mentioned transition process indication parameters based on each animation frame interpolate the above-mentioned first camera shooting parameters to obtain the camera parameters corresponding to each animation frame, which may include: based on the above-mentioned transition process indication parameters of each animation frame, interpolating the angle value range corresponding to the above-mentioned first camera shooting parameters to obtain the camera rotation angle corresponding to each animation frame.

[0088] For example, if the camera rotation angle in the first camera shooting parameter corresponding to the first virtual object is -180°, and the camera rotation angle in the first camera shooting parameter corresponding to the second virtual object is 180°, then the angle value range corresponding to the above first camera shooting parameter is -180° to 180°.

[0089] It can be understood that since the camera rotation angle corresponding to each animation frame is determined based on the angle value range corresponding to the first camera shooting parameter, the shooting transition can be indicated by the change in the camera rotation angle, that is, in the process of transitioning from shooting for the first virtual object to shooting for the second virtual object, the closer the virtual camera is to the second virtual object, the closer the camera rotation angle corresponding to the animation frame is to the camera rotation angle corresponding to the second virtual object, thereby making the shooting transition in the captured animation frame more natural.

[0090] For example, Figures 3 to 5 As shown, in Figure 3 In the virtual scene shown, when the transition shooting process reaches 10%, the camera rotation angle corresponding to the animation frame is close to the camera rotation angle corresponding to character A, indicating that the virtual camera begins to transition shooting towards character B. Figure 4 In the virtual scene shown, when the transition shooting process reaches 50%, the camera rotation angle corresponding to the animation frame is the median between the camera rotation angle corresponding to character A and the camera rotation angle corresponding to character B. Figure 5 In the virtual scene shown, when the transition shooting process reaches 90%, the camera rotation angle corresponding to the animation frame is close to the camera rotation angle corresponding to character B, that is, the virtual camera is about to shoot character B completely.

[0091] Step 104 : Based on the second camera shooting parameters, control the virtual camera to shoot multiple animation frames in the virtual scene to obtain an object transition animation.

[0092] In this embodiment, the second camera shooting parameters corresponding to the plurality of animation frames are used to show the changes in the shooting parameters during the camera shooting transition process, such as the change in the gaze point, so as to control the movement trajectory of the virtual camera during the transition shooting process to be smoother. Figure 6 As shown, Figure 6 The figure shows the poses of the virtual camera corresponding to different animation frames during the transition shooting process. It can be seen that by controlling the virtual camera based on the shooting parameters of the second camera, the movement trajectory of the virtual camera during the transition shooting process can be smoother.

[0093] In some embodiments, based on the above-mentioned second camera shooting parameters, controlling the above-mentioned virtual camera to shoot multiple animation frames in the above-mentioned virtual scene to obtain the object transition animation may include: based on the above-mentioned target viewpoint and the above-mentioned camera parameters corresponding to each animation frame, controlling the virtual camera to shoot corresponding animation frames in the above-mentioned virtual scene to obtain the object transition animation.

[0094] Specifically, the above-mentioned camera parameters include camera posture indication parameters. The above-mentioned control of the virtual camera to shoot the corresponding animation frames in the above-mentioned virtual scene based on the above-mentioned target viewpoint and the above-mentioned camera parameters corresponding to each animation frame may include: determining the camera posture corresponding to each animation frame based on the above-mentioned target viewpoint and the above-mentioned camera posture indication parameters corresponding to each animation frame; and controlling the virtual camera to shoot the corresponding animation frame in the above-mentioned virtual scene based on the above-mentioned camera posture corresponding to each animation frame.

[0095] Among them, the above-mentioned camera posture is used to indicate the position and / or posture of the virtual camera when shooting the virtual scene. The camera posture can be used to control the virtual camera to maintain the corresponding position and posture when shooting, so as to capture the content that meets the expectations.

[0096] It can be understood that the above-mentioned camera posture is obtained based on the camera gaze point. Therefore, when the virtual camera is controlled based on the camera posture, the virtual camera can shoot the above-mentioned virtual scene toward the above-mentioned camera gaze point.

[0097] Specifically, the above-mentioned camera pose indication parameters include a camera rotation angle and a camera arm length. The above-mentioned determination of the camera pose corresponding to each animation frame based on the above-mentioned target viewpoint and the above-mentioned camera pose indication parameters corresponding to each animation frame may include: determining the direction vector of the above-mentioned virtual camera toward the above-mentioned target viewpoint based on the above-mentioned camera rotation angle and the above-mentioned target viewpoint; determining the relative position vector between the above-mentioned virtual camera and the above-mentioned target viewpoint based on the above-mentioned direction vector and the above-mentioned camera arm length; and determining the camera pose of the above-mentioned virtual camera based on the above-mentioned target viewpoint and the above-mentioned relative position vector.

[0098] For example, if the camera rotation angle is set to arm_rotation_blend, the target viewpoint can be used as a starting point, and arm_rotation_blend can be converted into a direction vector arm_direction_blend of the virtual camera toward the target viewpoint.

[0099] Then, set the camera arm length to arm_length_blend and the position of the target viewpoint to focus_point_blend, and the camera pose of the above virtual camera can be calculated, that is, focus_point_blend-arm_direction_blend*arm_length_blend.

[0100] From the above content, it can be seen that by obtaining the object gaze points corresponding to the first virtual object and the second virtual object in the virtual scene respectively, the above object gaze points are the gaze points of the virtual camera when shooting the virtual objects; the first camera shooting parameters of the above virtual camera when shooting the corresponding virtual objects are determined; based on the above object gaze points and the above first camera shooting parameters, the second camera shooting parameters of the multiple frames of animation frames to be shot by the above virtual camera during the transition shooting process are determined, and the above transition shooting is the transition from shooting for the first virtual object to shooting for the second virtual object; based on the above second camera shooting parameters, the above virtual camera is controlled to shoot multiple animation frames in the above virtual scene to obtain the object transition animation, so as to obtain the second camera shooting parameters of the multiple frames of animation frames in the transition shooting process through the object gaze points corresponding to each virtual object, which are used to control the virtual camera to perform transition shooting, so as to make the animation presentation effect of the transition shooting between the two virtual objects more natural and enhance the player's visual experience.
