Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Before describing embodiments of the present application, some terms involved in the present application will be first described.

1. Game engine: a software development environment designed for creating real-time interactive contents is mainly used for developing electronic games in early stages, and is now widely used in other fields, such as animation production, special effect production, etc.

2. Real-time animation pipeline: the computer calculates the picture and outputs and displays the picture, and the frame rate reaches at least 25 frames and above so that the human eyes feel coherent and real-time. The game engine allows teams to quickly obtain high resolution assets, physical-based simulations and movements, realistic textures and cloths, a wide variety of particle effects, as well as cameras and complex lighting. The method has the advantages of real-time control, rapid iteration and rapid creative decision making which cannot be realized in the past.

3. Virtual camera: the camera in the game engine can be manually controlled by a user, directly assigned or driven by a mobile terminal device (such as a mobile phone, a tablet and the like). In some embodiments, the virtual camera may also be referred to as a virtual video camera, virtual lens, virtual camera, etc., as the application is not limited in this regard.

4. Sequence r: the multi-track editor of the illusion engine is used for creating and previewing the cutscene sequence in real time. By creating a Level Sequences (Level Sequences) and adding Tracks (Tracks), the user can define the composition of the individual Tracks and thus determine the content of the scene. The Track may contain Animation (Animation) for animating characters, deformation (Transformation) for moving everything in the scene, audio (Audio) for including music or sound effects, several other Track (Track) types, etc.

5. Nonlinear clipping: is a modern splicing approach in the post-production of movies and television, which means that any one frame in a video clip can be accessed.

6. Lens language: it is the story that is told with the lens. From the change of the shot subject and picture, the content to be expressed by the shot person through the lens is felt.

7. Animation: is a form of expression. Animation is a comprehensive art, which is an artistic expression form integrating a plurality of artistic categories such as painting, cartoon, movie, digital media, photography, music, literature and the like.

8. Video: is a playing mode. Video generally refers to various techniques for capturing, recording, processing, storing, transmitting, and reproducing a series of still images as electrical signals. When the continuous image changes more than 24 frames of pictures per second, according to the persistence of vision principle, the human eyes cannot distinguish a single static picture; it appears as a smooth continuous visual effect, such that successive pictures are called videos. Animation and video are also important media forms in multimedia technology, and have very deep sources. Animation and video are often considered to be the same thing, mainly because they all fall into the category of "dynamic images". The dynamic image is a continuously progressive still image or a sequence of graphics, which are sequentially displayed in a changing manner along the time axis, thereby producing a media format for the motion vision perception. However, animation and video are in fact two different concepts. Each frame of the image of the animation is generated manually or by a computer. The still image frames are sequentially played at a speed of 15 frames/second to 20 frames/second according to the characteristics of the human eyes, and a sense of movement is generated. Each frame of image of the video is obtained by capturing a natural scene or moving object in real time. The video signal may be generated by a continuous image signal input device such as a video camera, video recorder, or the like.

Referring to fig. 1, a schematic diagram of an implementation environment of an embodiment of the present application is shown. The solution implementation environment can be implemented as an architecture of a configuration system for a virtual camera. The implementation environment of the scheme can comprise: a terminal device 100 and a server 200.

The terminal device 100 may be an electronic device such as a PC (Personal Computer ), a tablet, a cell phone, a wearable device, an in-vehicle terminal, or the like. A client running a target application, which may be an application having an animation function, such as a game engine, may be installed in the terminal device 100. Illustratively, the target application is a game engine that can run a mirror tool, and configure the virtual camera according to the mirror tool to generate the virtual camera sequence. The mirror tool can be based on a plug-in the target application program or can be independent of the application program outside the target application program. In addition, the present application is not limited to the form of the target Application program, including but not limited to App (Application), applet, etc. installed in the terminal device 100, but may also be in the form of a web page.

The server 200 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud computing services. The server 200 may be a background server of the target application program, and is configured to provide a background service for a client of the target application program.

Communication between the terminal device 100 and the server 200 may be performed through a network, such as a wired or wireless network.

In the method for configuring a virtual camera according to the embodiment of the present application, the execution subject of each step may be a terminal device, and taking the implementation environment of the solution shown in fig. 1 as an example, the method for configuring a virtual camera may be executed by the terminal device 100, for example, a client of a target application installed and running in the terminal device 100 executes the method for configuring a virtual camera, and for example, a mirror tool installed and running in the terminal device 100 executes the method for configuring a virtual camera.

In the related art, to configure a virtual camera sequence, a designer first needs to put forward a mirror idea to an animation producer, and the animation producer manually records the animation of the virtual camera in the animation sequence in the form of a key frame in a game engine, so that complex animation motions need to be repeatedly calculated, adjusted, smoothed and other operations. The planner and the animation producer can communicate with each other for multiple rounds and repeatedly modify the animation, so that the production of the lens animation can be finished finally.

As shown in fig. 2, a column with punctual identifiers therein represents a key frame, such as key frame 210, wherein a column of punctual identifiers is used to represent the location and configuration parameters of the virtual camera in the virtual scene in the key frame. For example, the punctuation marks in the keyframe 210 represent, in order from top to bottom, the x-axis coordinates, y-axis coordinates, z-axis coordinates, roll parameters, pitch parameters, yaw parameters, scale parameters of the virtual camera in the virtual scene. Each key frame may set one or more of the parameters described above, e.g., only y-axis coordinates and z-axis coordinates are set in key frame 220. The planners and animation makers often judge how to set a certain machine position and a certain motion path through pictures obtained by shooting by the virtual camera, and then manually set key frames as shown in fig. 2, so as to complete the configuration of a virtual camera sequence.

However, in the virtual scene, the position information and the information of the relative relation between the virtual object and the virtual camera can be obtained in real time, the logic time and effort for designing the lens language by the picture watching effect are consumed, and the natural advantage of the virtual environment is not utilized. And the lens language of a section of animation often needs to be modified and iterated many times to be finally determined, if the key frame of a section of animation of the virtual camera is already set, and the whole lens is required to be moved backwards by a certain distance, each key frame needs to be modified, and the iteration cost is high and repeated communication with animation production needs to be planned.

The embodiment of the application provides a configuration method of a virtual camera, which can import data into a mirror transporting tool, determine configuration parameters of the virtual camera according to the imported data, and further generate a virtual camera sequence. And determining configuration parameters of the virtual camera by utilizing the relation between the positions of the virtual object and the virtual camera in the virtual scene and the shooting picture of the virtual camera, and automatically generating a virtual camera sequence without manual adjustment of an animation producer.

Referring to fig. 3, a flowchart of a method for configuring a virtual camera according to an embodiment of the application is shown. The method may be performed by the terminal device 100 shown in fig. 1. The method may include at least one of the following steps 310-340.

Step 310, a user interface of the mirror tool is displayed, with an import control displayed in the user interface.

The mirror tool refers to a tool for configuring the virtual camera, and the mirror tool may be a separate application program or may be a plug-in based on a target application program (such as a game engine), which is not limited in this application.

The user interface of the mirror tool refers to an interface for human-machine interaction in which an animator can configure a virtual camera to generate a virtual camera sequence.

If the mirror tool is a game engine-based plug-in, the user interface of the mirror tool may be a user interface independent of the game engine, or may be an interface area displayed in the user interface of the game engine, which is not limited by the present application. Illustratively, the user interface of the mirror tool may be a separate user interface 400 as shown in FIG. 4, or may be one of the interface regions 510 in the user interface of the game engine as shown in FIG. 5.

At least one control used for configuring the virtual camera is displayed in the user interface of the mirror transporting tool, and an animation producer can realize operations of adding, deleting, modifying, shearing, migrating and the like of the virtual camera according to each control included in the user interface.

In some embodiments, an import control is displayed in the user interface for importing data into the mirror tool. Illustratively, as shown in FIG. 4, an import control 401 is displayed in the user interface 400.

In response to the operation for the import control, a virtual camera sequence generated from import data is displayed, the virtual camera sequence including at least one virtual camera, the import data defining a category and an order of the respective virtual cameras, step 320.

In some embodiments, the imported data is imported into the mirror tool in a pre-set canonical form. The present application is not limited to the canonical form. For example, the canonical form may be in the form of a table, or may be in the form of text.

As shown in table 1, the imported data may include the following, for example, in the form of a table in the canonical form.

The first 3 columns of the plan description, time and range shown in table 1 are normalized descriptions by the animator countermeasure description for the animation ideas that the planner provides to the animator, to obtain the table composed of the last six columns shown in table 1. The six tables in the last column of table 1 are the imported data in the standard form.

In some embodiments, the category of the virtual camera is determined by the class of the mirror and the name of the mirror, and the order of the virtual cameras is in turn determined by the start frame and the end frame of the virtual camera.

The lens class refers to classification obtained according to lens rules of the virtual camera, and can comprise fixed positions, basic lens and programmed lens generation. The fixed camera position means that the virtual camera is in a fixed position for shooting. The basic moving mirror means that the virtual camera shoots according to basic movement rules, for example, the virtual camera shoots in a push-pull mode. The programmatically generating the lens refers to a relatively complex lens-moving method, such as a circular surrounding lens-moving method, in which the virtual camera performs circular surrounding shooting with the shooting object as the center.

The mirror name refers to the name of the mirror mode of the virtual camera. For example, the long-range view is a long-range view of a subject, in which a virtual camera photographs at a fixed position and the photographed image is a captured image. The close-up is that the virtual camera shoots at a fixed position, and the shot picture is the close-up picture of the shooting object. Push-pull means that the virtual camera shoots a shooting object in a push-pull manner according to a motion track.

Table 1: importing data examples

The frame starting is used for determining the position when the virtual camera starts shooting, the frame dropping is used for determining the position when the virtual camera ends shooting, the starting frame refers to the time stamp when the virtual camera starts shooting, and the ending frame refers to the time stamp when the virtual camera ends shooting.

Of course, the imported data may include not only the class of the mirror, the name of the mirror, the starting frame, the falling frame, the starting frame, the ending frame, but also other data information of the virtual camera, which is not limited in the present application. For example, the imported data further includes a subject of the virtual camera. The photographed object refers to a virtual object photographed by a virtual camera in a virtual scene. The virtual object may be a virtual character in a virtual scene or a virtual object in a virtual scene, which is not limited in the present application. For example, the virtual object may be a game character or a virtual object in a game scene.

In some embodiments, the imported data may or may not include the shooting objects corresponding to the virtual cameras.

For example, if the photographed objects of the virtual cameras in the virtual camera sequence are the same (for example, the photographed objects of the virtual cameras in the virtual camera sequence are all virtual object 1), the imported data may include the photographed objects corresponding to the virtual cameras, or may not include the photographed objects corresponding to the virtual cameras, or may be set in a unified manner.

For example, if there is a difference in the photographed objects of the respective virtual cameras in the virtual camera sequence (for example, the photographed objects of the respective virtual cameras in the virtual camera sequence include the virtual object 1, the virtual object 2, and the virtual object 3), the photographed objects respectively corresponding to the respective virtual cameras may be included in the imported data. The virtual camera sequence is a virtual camera arranged in a shooting time sequence, and the virtual camera sequence comprises at least one virtual camera, and pictures shot by each virtual camera can obtain a video. Illustratively, as shown in table 1, the respective virtual cameras included in the virtual camera sequence are arranged in the order of the start frame and the end frame shown in table 1.

In some embodiments, virtual cameras may be categorized according to their mirror rules.

For example, a virtual camera is divided into a fixed lens and a dynamic lens according to whether it moves.

For example, the virtual cameras may be classified according to the above-mentioned classes of the mirrors, and the classes of the virtual cameras may be classified into fixed positions, basic mirrors, and programmed mirrors.

For example, the virtual cameras may be divided according to the names of the above-mentioned fortune mirrors, and the kinds of the virtual cameras may be divided into long-range view, short-range view, medium-range view, push-pull view, circular surround view, and the like.

In some embodiments, the import data is imported into the mirror tool in the form of a file, for example, the import data is imported into the mirror tool in the form of an excel table file.

In some embodiments, in response to an operation on the import control, a file selection interface is displayed in which at least one file is displayed; and in response to the selection operation on the target file, importing the data stored in the target file into the mirror carrier.

Illustratively, in response to operation of the import control 401 in FIG. 4, a file selection interface 600 is displayed as shown in FIG. 6, in which the user may select a target file. In response to a selection operation for the target file 610, the data stored in the target file 610 is imported into the mirror tool.

Illustratively, as shown in FIG. 4, a virtual camera sequence 402 is generated and displayed from the imported data, the virtual camera sequence 402 including at least one virtual camera therein. In some embodiments, the sequence of virtual cameras is displayed in the order of the virtual cameras. For example, taking the virtual camera shown in table 1 as an example, the virtual camera sequence is displayed in the order of fixed machine position-perspective, base fortune mirror-push-pull, fixed machine position-perspective, programmatically generated fortune mirror-circular surround, fixed machine position-perspective, base fortune mirror-push-pull.

In some embodiments, the type of virtual camera may be determined according to the mirror name included in the imported data, the order of the virtual cameras may be determined according to the start frame and the end frame included in the imported data, and thus the configuration parameters of the virtual cameras may be determined.

In some embodiments, the pictures taken by the virtual camera in the same lens-transporting mode are similar in picture composition, for example, the virtual camera adopts a close-up lens-transporting mode to take the eyes of the shooting object, and then in the virtual scene, after determining the position of the shooting object of the virtual camera, the position of the virtual camera can be determined according to the relationship between the distance between the virtual camera and the shooting object and the pictures taken by the virtual camera. For example, in the case where the distance between the virtual camera and the subject is 10m, the head of the subject is included in the screen captured by the virtual camera, and in the case where the distance between the virtual camera and the subject is 5m, the half-face of the subject is included in the screen captured by the virtual camera, based on which the position of the virtual camera can be easily determined.

In some embodiments, the order of the individual virtual cameras may be determined from the start and end frames in the imported data.

By the method, the virtual camera sequence can be automatically generated according to the imported data, animation production personnel are not required to manually adjust the position of the virtual camera, the operation is simple, and the efficiency is high.

In some embodiments, import data is obtained in response to an operation on an import control; for a virtual camera defined by the imported data, determining configuration parameters of the virtual camera according to the type of the virtual camera and the position information of a shooting object; and generating and displaying a virtual camera sequence according to the sequence of each virtual camera defined by the imported data and the configuration parameters of each virtual camera.

In some embodiments, the location information of the shooting object may be location information of the shooting object in the virtual scene, or may be bone information of the shooting object. The bone information of the photographic subject may include bone composition of the photographic subject, position information of the bone of the photographic subject in the virtual scene, bone orientation of the photographic subject.

In some embodiments, if the type of the virtual camera is a fixed lens, a configuration parameter of the virtual camera is determined according to the position information of the shooting object, where the configuration parameter of the virtual camera includes a position of the virtual camera.

In some embodiments, if the type of the virtual camera is a dynamic lens, the configuration parameters of the virtual camera are determined according to the position information of the shooting object, and the configuration parameters of the virtual camera include the position and the motion trail of the virtual camera.

The virtual camera is illustratively a fixed-camera-position long-range camera, and the position of the virtual camera is determined according to the type of the virtual camera and the position information of the shooting object.

The virtual camera generates a mirror circular surrounding camera for programming, and the position of the virtual camera and the movement track of the virtual camera are determined according to the type of the virtual camera and the position information of a shooting object. The motion trail of the virtual camera can be expressed by spline lines and spline points. Spline refers to a line presented in the preview screen for describing the motion trail of the virtual camera, and spline points refer to points on the spline for describing key frames of the motion trail of the virtual camera.

In some embodiments, the configuration parameters of the virtual camera are determined according to the type of the virtual camera, the position information of the photographing object, and the orientation of the photographing object.

In response to the operation for a first virtual camera of the at least one virtual camera, configuration parameters of the first virtual camera are displayed, the configuration parameters being used to determine a mirror rule for the virtual camera in the virtual scene, and the configuration parameters being automatically generated by the mirror tool from the imported data, step 330.

Illustratively, as shown in FIG. 4, in response to an operation for a first virtual camera 402a of the at least one virtual camera, configuration parameters 403 of the first virtual camera are displayed. The configuration parameters of the first virtual camera are used to determine a mirror rule of the virtual camera in the virtual scene, which may include at least one of: the position of the virtual camera, the motion track, the number of spline points, the running speed, the motion radius, whether the motion is reversed, the spline proportion, the shooting object, the amplitude and the like.

The spline of the virtual camera refers to the motion trail of the virtual camera, and the spline of the virtual camera refers to a key frame on the motion trail of the virtual camera. The radius of motion is used to describe the range of motion of the virtual camera.

In some embodiments, the user interface also displays therein a diagrammatic configuration parameter of the first virtual camera, the detailed configuration parameter of the first virtual camera being displayed in response to operation of the first virtual camera with respect to the at least one virtual camera. Illustratively, the diagrammatic configuration parameters of the first virtual camera may be displayed in a first area 404 of the user interface 400, and the detailed configuration parameters 403 of the first virtual camera are displayed in the user interface 400 in response to operation for the first virtual camera.

In some embodiments, the outline configuration parameters correspond to simple mirror rules of the virtual camera, such as the position of the virtual camera, the rotation angle of the virtual camera, etc.; the detailed configuration parameters correspond to the responsible mirror rules of the virtual camera, such as the number of spline points, spline proportions, etc. of the virtual camera.

In some embodiments, the configuration parameters of the virtual camera are automatically generated by the mirror tool based on the imported data without manual setting by the animator.

In response to the configuration save operation for the virtual camera sequence, step 340, configuration information for the virtual camera sequence is saved, the configuration information including configuration parameters for each virtual camera included in the virtual camera sequence.

In some embodiments, the generated virtual camera sequence may be saved and applied in an animation sequence.

In some embodiments, a save control is also displayed in the user interface that saves configuration information for the virtual camera sequence in response to a configuration save operation for the virtual camera sequence (e.g., clicking on the save control after selecting the virtual camera sequence).

Illustratively, as shown in FIG. 4, the configuration information for the virtual camera sequence is saved in response to a configuration save operation for the virtual camera sequence (e.g., after the virtual camera sequence is selected, the save control 405 is clicked). For example, a path selection interface as shown in fig. 6 may be displayed, and the user may select a target storage path in the path selection interface, and store configuration information of the virtual camera sequence into the target storage path in response to a selection operation for the target storage path. The target storage path is determined in the path selection interface.

According to the technical scheme provided by the embodiment of the application, the mirror tool automatically generates and displays the virtual camera sequence by importing data into the mirror tool so as to complete the configuration of the virtual camera. The virtual camera is not required to be manually adjusted by an animation producer, and the position and the motion trail of the virtual camera are determined according to the picture shot by the virtual camera, so that the process of configuring the virtual camera is simplified, the operation is simple, and the efficiency of configuring the virtual camera is improved.

In some embodiments, the method provided by the embodiment of the application further supports modification of the configuration parameters of the virtual camera.

In some embodiments, after step 330, step 350 is also included.

In step 350, the modified configuration parameters of the first virtual camera are displayed in response to the modification operation for the configuration parameters of the first virtual camera.

Illustratively, as shown in FIG. 4, the animator may perform a modification operation on the configuration parameters 403 of the first virtual camera displayed in the user interface 400, such as the configuration parameters of the first virtual camera being editable, and display the modified configuration parameters of the first virtual camera in response to the modification operation on the configuration parameters of the first virtual camera.

In some embodiments, a modification control may be displayed in the user interface, the configuration parameters of the first virtual camera are adjusted to an editable state in response to operation of the modification control, and the modified configuration parameters of the first virtual camera are displayed in response to modification operation of the configuration parameters of the first virtual camera. Illustratively, the modified start frame of the first virtual camera is displayed in response to a modification operation for the start frame of the first virtual camera. Illustratively, the modified coordinate position of the first virtual camera is displayed in response to a modification operation for the coordinate position of the first virtual camera in the virtual scene.

By the method, the configuration parameters of the virtual camera can be adjusted in a self-defined manner by the animation producer under the condition of unsatisfied virtual camera sequence generated automatically.

In some embodiments, at least one preset virtual camera is also displayed in the user interface, the preset virtual camera having at least one initial configuration parameter.

In some embodiments, the initial configuration parameters corresponding to different preset virtual cameras may be the same or different. For example, the initial configuration parameters corresponding to the preset distant view camera and the initial configuration parameters corresponding to the preset close view camera may be the same or different. For example, initial positions of the preset far-view camera and the preset near-view camera are all original point positions in the virtual scene. For example, the distance between the initial and the shooting object corresponding to the preset distant view camera is 500m, and the distance between the initial and the shooting object corresponding to the preset close view camera is 200m.

Illustratively, as shown in FIG. 4, a plurality of preset virtual cameras 406 are displayed in the user interface 400, including fixed camera-perspective, fixed camera-close-up, base mirror-push-pull, programmatically generating mirror-circular surrounds, and the like.

Therefore, when the virtual camera is added, the animation producer only needs to select the corresponding preset virtual camera, and does not need to set the type of the virtual camera, so that the operation of adding the virtual camera is simplified.

In some embodiments, embodiments of the present application also support adding virtual cameras in a virtual camera sequence.

Illustratively, the step of adding a virtual camera may include at least one of the following steps 1-3.

For example, the first time stamp is 10s, the second time stamp is 20s, and if the pointer time is 10s, the fourth virtual camera in the virtual camera sequence is switched to the target virtual camera, and the shooting period of the target virtual camera starts from 10s to 20 s.

And 3, if the pointer time is between the first timestamp and the second timestamp, adding a target virtual camera in the virtual camera sequence, and adjusting the shooting period of the fourth virtual camera from the first timestamp to the pointer time, wherein the shooting period of the target virtual camera from the pointer time to the second timestamp.

For example, the pointer time is located at the third time stamp 1030, and the photographing period of the fourth virtual camera is adjusted from the start of the first time stamp 1010 to the end of the third time stamp 1030, and the photographing period of the target virtual camera is adjusted from the start of the third time stamp 1030 to the end of the second time stamp 1020.

For example, if the first time stamp is 10s and the second time stamp is 20s, and the pointer time is 15s, the target virtual camera is added to the virtual camera sequence, and the shooting period of the fourth virtual camera is adjusted from 10s to 15s, and the shooting period of the target virtual camera is adjusted from 15s to 20 s.

The public preset adding module rewrites the coordinate position, focal length, shooting object, focal distance and other information of the virtual camera in the virtual scene by calling stored information of different preset objects (including the preset virtual camera) and combining the read skeleton information of the shooting object, and draws spline lines of different motion tracks in real time to complete the generation and instantiation of the virtual camera.

Referring to fig. 12, a block diagram of a lens and sequence creation module of a mirror carrier according to an embodiment of the application is shown.

After the virtual camera generation instantiation is completed, each virtual camera exists in the virtual scene, can directly display and call, and can also be used for outputting real-time signals such as real-time rendering. If a real-time rendering sequence is desired or a virtual camera sequence is involved in advance, an animation sequence needs to be created. The animation sequence includes a virtual camera sequence, an audio track, an animation of a photographed object, and the like.

The user can input the initial frame, the end frame and the frame rate generated by the animation sequence or fill in the normalized shot script, and click the create sequence button to trigger the generation of the animation sequence function. The function creates an animation sequence, creates a virtual camera array for the selected virtual camera, and creates necessary motion tracks and key frames for each virtual camera in the created animation sequence by traversing the virtual camera array and judging configuration parameters of each virtual camera, so that the motions of the virtual cameras can be reproduced in the animation sequence.

The mirror tool simultaneously provides another user interface, so that a user can modify the configuration parameters of the virtual camera in real time through the user interface, and the motion rules of the virtual camera and the motion rules in the animation sequence can be rewritten in real time.

The mirror tool provides a conversion function at the same time, so that the virtual camera sequence based on the mirror tool can be converted into the virtual camera sequence supported by the game engine, and the animation sequence based on the mirror tool can be converted into a common animation sequence, and the operation of the mirror tool is not depended.

Referring to fig. 13, a block diagram of a quick editing and previewing module of a mirror carrier according to an embodiment of the present application is shown.

The switching logic of the virtual camera with the animation sequence is complex and can not preview the shot picture of each camera at the current time point, so that the mirror-transporting tool simultaneously provides a user interface capable of simulating the signal switching table, and a user can rapidly finish the functions of editing the virtual camera and previewing the virtual camera.

Clicking the start preview control, displaying real-time images of all virtual cameras in the virtual camera sequence in the user interface, selecting a certain virtual camera, and binding the current virtual camera track by the virtual camera switching sequence track, wherein the range is from the current frame to the end frame, and each section is switched into a virtual camera chapter (shooting period of one virtual camera).

When the virtual camera sequence is quickly clipped, the mirror tool will first determine whether the current frame is within a certain completed virtual camera chapter. If the current frame is the initial frame of a certain virtual camera chapter, selecting a target virtual camera, converting the virtual camera binding of the virtual camera chapter into a target virtual camera binding picture, if the current frame is positioned in the middle of the certain virtual camera chapter, segmenting the virtual camera chapter, wherein the front part of the current frame is the original virtual camera binding picture, and the rear part of the current frame is the target virtual camera binding picture.
