Current animation is mostly based on editing of a timeline, which is an abstract representation that simulates the time lapse of an animation. As shown in fig. 1 and 2, after the animation starts to be played in the timeline editor, the timeline moves from left to right, representing the lapse of time. During animation, tracks can be added in the editor to control the characters and resources that appear in the animation. The specific control mode is to set command bars on the track. When the timeline passes a certain command bar of the track, the command is executed. Thus, specific roles, special effects, etc. elements can be created at specific points in time of the timeline. And various actions of the character, such as moving, playing bone animation and the like, can be controlled at a specific position of the time line.

Referring to FIG. 4, a schematic diagram of an animation system according to a preferred embodiment of the invention is shown. In this embodiment, the animation system includes an animation rendering engine and a timeline editor, where the animation rendering engine may be a unity2019.1 version engine, and the timeline editor is a commonly used editor framework, and may be fully developed independently without depending on a specific development platform. The animation rendering engine will design the formation behavior instructions according to the designer of the animation to be used as control of the out-going objects that appear within the animation. The outgoing object is an object appearing in the picture of the animation, such as everything presented in the picture, such as a man and woman owner, an animal image, a building, weather, magic skills, and the like. The behavior instructions for the outgoing object are image changes such as appearance changes such as shape and structure, appearance changes such as morphology, and position and effect changes.
In this embodiment, to implement the classification type and collection type processing for the outgoing objects, the timeline editor relies on the timeline track of the animation, and includes a classification unit, an action giving unit and a control unit.
The classification unit obtains the behavior instructions of each outgoing unit, or edits the behavior actions of each outgoing object according to the design of the animation designer, for example, the main angle of a man of the animation is designed to lift the left hand, apply boxing, speak with the mouth, or the match angle of the main angle is closed together with the mouth to speak, point to a certain direction, etc., when some outgoing objects have the same or similar behavior, for example, a plurality of objects are designed in the animation picture to simultaneously move from the left side of the picture to the right side of the picture at a similar speed, or a plurality of big trees designed in the animation picture swing along the wind, etc., the outgoing objects are regarded as having approximate behaviors, and after judging that the approximate behaviors are obtained, the outgoing objects are moved along the windThe ex-field objects are clustered into one cluster, and the like, and the ex-field objects are clustered into a first cluster and a second cluster on the basis of the behavior of the ex-field objects in all the ex-field objects. . . Nth cluster where n e Z + . That is, all the outgoing objects are grouped and categorized based on the similarity of the behavior of the outgoing objects. The behavior similarity referred to in this embodiment includes the similarity of appearance changes of a plurality of panelists, such as a regular large mouth, a smiling face, and the like, and also includes the similarity of action behaviors of a plurality of panelists, such as a regular hand lifting, a simultaneous leg lifting, and the like, and also includes the similarity of positions of a plurality of panelists, such as all walking from left to right (regardless of walking distance, only direction). It will be appreciated that, depending on the division of the behavior similarity, the number of clusters may be different, and all the outgoing objects may be clustered in one cluster (first cluster), or every two outgoing objects may be clustered in one cluster (first cluster, second cluster, etc.).
After the collection of the presence objects into clusters, the action imparting unit will impart to each cluster an object behavior such that the presence objects within the same cluster have the same behavior. For example, the first cluster is given object behavior in which these ex-presence objects lift both hands for a certain period of time, and for example, the second cluster is given object behavior in which these ex-presence objects fly from the left side to the right side of the animated picture for a certain period of time. When assigning object behavior to clusters, the object behavior assigned to different clusters is different (if the same, the clusters may merge) such that the presence objects within different clusters perform different actions according to the design. In this embodiment, it may be appreciated that the assignment of the cluster to the action may not have precedence or causal relationships, and first when the outgoing object is clustered within a certain cluster, it is not indicated that the outgoing object has a certain behavior, nor that the outgoing object has a certain similarity of behavior with other outgoing objects within the cluster, but that part of the outgoing objects may or should have a certain behavior according to future designs of animation designers, and are clustered within a certain cluster according to the possible behavior in the future. And a combined action giving unit which gives the object behavior designed when the animation designer gathers out the field object. That is, the classification unit and the action assignment unit are grouped and assigned based on the same future behavior of the animated designer for the presence object.
The control unit is internally provided with spontaneous behavior instructions, after the object is collected and endowed with the object behavior during animation design, the object is collected in a certain cluster after the execution according to the object behavior on the time axis of the animation, but after the object behavior endowed by the action endowing unit is finished according to the design, the corresponding instructions are executed through the control of the spontaneous behavior instructions of the control unit so as to display further behavior. For example, all birds within an animation screen are grouped into a certain cluster, and the object behavior imparted to the cluster by the action imparting means appears to fly from the lower left of the screen to the middle of the screen. When birds, which are the objects of the present, fly from the lower left of the picture to the middle of the picture, the behavior of the object is performed, and the spontaneous behavior instructions are that the birds randomly spread from the middle to the periphery of the picture, so that the whole behavior of the birds in the picture appears to fly from the lower left of the picture to the middle and then spread to the periphery. That is, the control unit gives the cluster a certain behavior autonomy, and when the object performance is completed or some other condition is met, the outgoing objects in the cluster execute random, preset or certain behaviors.
In the whole process of the time line moving, if the cluster where the object unit is located is issued with the object behavior, the object unit generates behavior according to the command of the cluster; if the object unit completes the command of the object behavior of the cluster or does not receive the command of the object behavior of the cluster, spontaneous behavior is generated according to the judgment of the control unit.
Through the configuration, on one hand, after the outgoing objects are collected, a certain action design can be uniformly carried out on part of the outgoing objects in a cluster mode, and on the other hand, the outgoing objects have certain behavior autonomy due to the arrangement of the control unit, so that the thought of animation design personnel on an animation design scheme is saved, and the expressive force of pictures is enriched.
With continued reference to FIG. 4, in a preferred embodiment, to facilitate the design and production of animations, the categorization defines each of the outbound objects as an object unit by unit, and the action design is performed for each outbound object in the form of a minimum unit. Each object unit is provided with a unit expression element and a unit control element, the unit expression element renders appearance changes to the object unit so as to display the appearance changes of the object unit, and the unit control element renders object behavior expressions to the object unit so that the object unit makes certain behaviors. For example, when the object unit receives a command to move to a certain position, the unit control unit controls the object unit to move to the position, and if the object unit collides with other object units, the object unit is avoided. After pre-designing the appearance change and/or the object behavior of the object unit, the classification unit defines the behavior similarity of the object on the basis of the similar appearance change and/or behavior change.
Further, each cluster includes a cluster control element and a cluster command element, the cluster control element being connected to the action imparting unit, receiving the imparted object performance, and being connected to the unit control element to impart the object performance thereto. That is, the object behavior of the plurality of object units designed by the animation designer will be given to each object unit within the cluster by the action giving unit, the cluster control unit, the unit control unit. The cluster command element is connected with the control unit, receives the spontaneous behavior instruction designed by the animation personnel, is connected with the unit control element, and gives the spontaneous behavior instruction to the unit control element, so that part or all of the object units in the same cluster execute the autonomous behaviors included in the spontaneous behavior instruction.
In order to confirm whether the object units perform corresponding object behavior, a state machine is provided in each object unit, wherein the state machine indicates the behavior state of the object unit, for example, the behavior state of the object unit recorded by the state machine may be that the object unit is static, moves in a screen at a certain speed, changes from small to large, and the like. The state machine sends the behavior state of the object unit to the control unit, and after the control unit acquires the behavior state change of the object unit, the control unit acquires whether the object unit has executed the behavior of the object, or triggers other conditions (such as reaching a certain position and executing the action to a certain completion degree), the control unit sends a spontaneous behavior instruction to the cluster command unit, so that the object unit executes the spontaneous behavior. For example, the control unit knows whether the object unit is moving or is an attack target at the current time, and the control unit controls the object unit to perform corresponding actions, for example, the control unit can set to stand in place to wait after the object unit moves to a specified place.
Considering that it is possible to perform the same or different object performance at some moments of the timeline even for the same or similar object units, as shown in fig. 5, some object units are clustered into the second cluster within 1-5 seconds and 6 seconds are clustered into the first cluster (but still can be clustered into the second cluster), in the case that the object units perform the object performance or spontaneous behavior instruction with the highest priority according to the priorities of the object performance and spontaneous behavior instructions when the object units receive at least two object performance or spontaneous behavior instructions at the same moment. Depending on the priority, an object unit in a cluster may stop its current object behavior and instead perform a particular action unless the current object behavior or spontaneous behavior instruction has a higher priority than the object behavior or spontaneous behavior instruction. Such as attacking a certain cluster/object unit, evading a certain cluster/object unit, cluster reorganization, etc., may be used as a cluster command.
In a further preferred embodiment a track model of the control clusters is added in the timeline editor, on which track various cluster commands can be created. Cluster commands include cluster creation, cluster movement, cluster behavior, and the like. Specifically, when the classification unit gathers the outgoing objects into clusters, any one or more of a cluster unit model, a cluster arrangement model, the number of cluster units and a cluster behavior instruction of each cluster are set. The clustered unit model may be a type of clustered unit, such as people, animals, plants, buildings, weather, etc.; the cluster arrangement model is a preset mode of arranging object units in a cluster, such as a straight-line mode, a zigzag mode, an F mode, an S mode and the like; the number of the cluster units represents the number of the object units included in each cluster after being clustered according to the behavior approximation degree; and the cluster behavior instruction is the object behavior. On the one hand, the cluster unit model, the cluster arrangement model, the number of cluster units and the arrangement of the cluster behavior instructions can increase the aggregation speed of the classification units or the endowing speed of the action endowing units in a preset mode. In addition, when the action giving unit gives the object behavior representation to each cluster, the object behavior representation includes any one or more of a target object, a moving target cluster, a moving target position, a moving speed, or a moving mode, wherein the target object is another target object to which the object unit moves, the moving target cluster represents which clusters will move in the screen according to the object behavior representation at a certain moment and rest, the moving target position represents a moving time end position of the object unit, the moving speed represents a speed of the object unit when moving, and the moving mode is a moving form of the object unit when moving, such as a linear form, a spiral form, a folded line form, and the like.
In the above embodiment, the track model of the control cluster added by the timeline editor may also be regarded as the track model set in the control unit, and by recording cluster creation, cluster movement and cluster behavior, the animation designer can control and grasp the animation.
In a further alternative embodiment, the timeline editor further comprises a reorganization unit that monitors the object behavior of all or part of the object units in any cluster, and when the object behavior of part of the object units is different, the reorganization unit issues a command to deconstruct the cluster, separate the object units from the cluster and cluster the object units with the same behavior similarity again to a new cluster, considering that the behavior similarities according to which part of the object units are not consistent in some time periods, i.e. the object units in the cluster are no longer consistent or similar, but should be partitioned into other clusters. It will be appreciated that, for deconstructing a cluster, it is not represented by complete decomposition of the cluster, but rather, some object units in the cluster may be extracted and placed in other clusters, or some object units in the cluster may be extracted from some object units in another cluster or clusters, and after a cluster is newly built, some objects are placed in the new cluster, so that commands are issued to the new clusters to execute corresponding object behavior.
For some object units with more specific behaviors, a separate track can be set for the object unit, and a specific object behavior can be given to the object unit. Specifically, the classification unit divides all object units into a main angle unit and an angle allocation unit according to the importance degree of the object units in the animation, or extracts the main angle unit only from the object units, and after determining the main angle unit, the classification unit divides the cluster of the main angle unit and the angle allocation unit into a cluster (or independent units) independently. And controlling all behaviors of the principal angle unit according to an original time line editing mode, namely configuring principal angle behavior manifestation and principal angle behavior instructions for the principal angle unit by using independent tracks. While the object units in other clusters, i.e. corner units, are presented only for some co-lining the corner units, because the behavior patterns are relatively uniform, the object behavior can still be configured for corner units in a uniform manner as described above.
Using this timeline editor, animation designers can concentrate on animating and rendering the primary character. For other numerous coordination angles, animation designers only need to distribute the coordination angles into a specific cluster, set autonomous behavior instructions of the cluster, set corresponding commands in a time line, and make the behavior of the coordination angles according to the commands. By combining the control unit and the action giving unit, the coordination angles can also show rich behaviors, and the animation scene is not distorted at all. In addition, animation designers do not need to spend excessive time on corner fitting, and can finish large-scale cluster animation by simple operation. Thus, a great deal of time can be saved for the user, and the animation production efficiency is greatly improved.
Example 1
The control unit can control each object unit in the cluster to make a behavior conforming to the command according to the characteristics of the cluster by replacing the behavior of manual editing by the control unit. The control unit will only function if no cluster command is received, which can be understood as a default nature. The cluster command can be used for enabling animation designers to issue commands to a plurality of object units in batches, and the object units are driven to make specific behaviors in a control unit mode, so that the animation designers can very conveniently control roles without specific instructions, and enable the animation designers to make proper behaviors. For example, the animation designer may configure the cluster as a bird cluster, and the control unit may configure the autonomous behavior instructions to fly around randomly. The animation designer may instruct this cluster to fly to a fixed point on the timeline. Each bird in the cluster flies to the fixed point at this time. When they all fly around this fixed point, the object performance is completed. At this point, the autonomous behavior instructions configured by the control unit come into effect, they fly randomly around, exhibiting a leisure state.

s100: the time line editor relies on a time line track of the animation, and a classification unit thereof clusters the outgoing objects with the same behavior similarity to a first cluster and a second cluster according to the behavior similarity of the outgoing objects. . .

the action imparting unit and the control unit impart individual principal angle behavior manifestations and principal angle behavior instructions to the principal angle unit.
9. A method of animation comprising the steps of:
the time line editor relies on a time line track of an animation, and a classification unit thereof classifies the out-of-the-field objects with the same behavior similarity into a first cluster and a second cluster according to the behavior similarity of the out-of-the-field objects + ；
The action giving unit of the time line editor gives the object behavior to each cluster, so that the outgoing objects collected into the same cluster have the same behavior, and the given object behavior of different clusters is different;
the control unit of the time line editor is internally provided with spontaneous behavior instructions, and when the execution of the outgoing objects in any cluster is completed, the outgoing objects receive the spontaneous behavior instructions and execute the spontaneous behavior instructions.
10. A computer readable storage medium having stored thereon a computer program, characterized in that the computer program when executed by a processor realizes the steps of:
the time line editor relies on a time line track of an animation, and a classification unit thereof classifies the out-of-the-field objects with the same behavior similarity into a first cluster and a second cluster according to the behavior similarity of the out-of-the-field objects + ；
The action giving unit of the time line editor gives the object behavior to each cluster, so that the outgoing objects collected into the same cluster have the same behavior, and the given object behavior of different clusters is different;
the control unit of the time line editor is internally provided with spontaneous behavior instructions, and when the execution of the outgoing objects in any cluster is completed, the outgoing objects receive the spontaneous behavior instructions and execute the spontaneous behavior instructions.
