Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms unless otherwise specified. These terms are only used to distinguish one element from another. For example, the first motion data may be referred to as second motion data, and similarly, the second motion data may be referred to as first motion data, without departing from the scope of the present application.

Fig. 1 is a diagram of an application environment of an animation data processing method provided in an embodiment, as shown in fig. 1, in the application environment, including a terminal 110 and a server 120. When animation motion data needs to be processed, for example, imported skeletal animation data needs to be reduced through a Unity engine of the terminal, the terminal 110 may obtain, from the server 120, an original key frame data set of a current animation object to be subjected to data processing, where the original key frame data set includes motion data of each key frame in a current transformation dimension, and then process the animation data by using the animation data processing method provided by the embodiment of the present invention, so as to reduce the data volume of the original animation data.

The Unity engine is a specialized game engine developed by Unity Technologies, and has good cross-platform performance, and animation can be created or animation data can be processed through the Unity engine. The terminal 110 may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, and the like. The terminal 110 and the computer device 120 may be connected through communication connection manners such as bluetooth, USB (Universal Serial Bus), or network, which is not limited herein. The server 120 may be an independent physical server, or may be a server cluster formed by a plurality of physical servers, and may be a cloud server that provides basic cloud computing services such as a cloud server, a cloud database, a cloud storage, and a CDN. In addition, it is understood that the animation data method provided by the embodiment of the invention can also be executed in a server. The raw key frame data set may also be stored in the terminal 110, and therefore, when the animation data needs to be processed, the terminal 110 may obtain the raw key frame data set from a local storage.

As shown in fig. 2, in an embodiment, an animation data processing method is provided, and this embodiment is mainly illustrated by applying the method to the terminal 110 in fig. 1. The method specifically comprises the following steps:

step S202, an original key frame data set corresponding to the current animation object to be subjected to data processing is obtained, wherein the original key frame data set comprises motion data of each key frame in the current transformation dimension.

In particular, animation may provide a visual effect to a viewer that the animated character changes continuously by playing a series of images continuously. The current animated object may be determined according to the particular animation. For example, for a character in an animation, the current animation object may be a hand of the animated character. For a tree in an animation, an animated object may be a branch of the tree. The key frame is a picture for representing a key action of the animated character in the animation. The locations of the keyframes in the animation may be set as desired. For example, the animation designer may design the pictures of the 1 st frame, the 5 th frame and the 15 th frame of each second animation according to the animation scene, and the 1 st frame, the 5 th frame and the 15 th frame are key frames, while the pictures corresponding to other non-key frames may be interpolated according to the positions, action states and time of the key frames by using a computer to obtain animation data of the non-key frames between the key frames. The motion data may include one or more of displacement motion data, rotational motion data, and zoom motion data. The displacement motion data may be used to represent the distance that the animated object moves over time. Rotational motion data may be used to represent the angle at which an animated object rotates over time. The scaling motion data may be used to represent the multiple by which the animated object is zoomed in or out over time. The transformation dimension is used to represent the direction of motion transformation of the animated object. The motion of the animation is directional, and a transformation dimension may represent a motion transformation direction for a type of motion. For example, in the case of a displacement motion, if the motion is a three-dimensional animation, the motion is described by a coordinate system and includes three motion directions: x-direction, Y-direction, and Z-direction, i.e., three transformation dimensions. The scaling motion is described in a coordinate system, and includes scaling in X, Y and Z different transformation directions. The motion data in the raw keyframe data set may include one or more transform dimensions. When a plurality of transformation dimensions exist, the motion data of only one of the transformation dimensions can be processed, namely, one of the transformation dimensions is used as the current transformation dimension. Motion data for multiple transform dimensions may also be processed. For example, the current transformation dimension may be an X dimension in the displacement motion, or may be an X dimension in the displacement motion and a Y dimension in the scaling motion. The motion data may include specific motion values and corresponding motion trends for the keyframes. The motion trend can be represented by the curvature of the motion curve, and the curvature can be further divided into a forward curvature and a backward curvature. Curvature refers to the rotation rate of the tangential angle of the points of the curve versus the arc length.

In one embodiment, the current animation object is a skeletal animation object, and when the current motion type is a displacement motion type and/or a rotation motion type, the motion data of each key frame in the original key frame data set in the current transformation dimension is relative motion data, and the relative motion data is motion data of the current animation object moving relative to a parent object of the current animation object. In the skeleton animation, the animation role of the skeleton animation has a skeleton structure formed by interconnected skeletons, each skeleton in the skeleton structure is an animation object, the animation objects have a hierarchical relationship, the motion data of the skeletons at the sub-level is the motion data when moving relative to the skeleton at the parent level, and the skeletons can move by controlling the displacement motion data, the rotation motion data and the scaling motion data of the skeletons to generate the animation.

For example, when the animated character is an animation, such as a puppy, the skeleton structure of the puppy is shown in fig. 3, wherein the torso is at a first level, and the head, left arm, right arm, left leg, and right leg are at a second level, and the torso is at a parent level of the head, left arm, right arm, left leg, and right leg. And a third level may be included below the second level. The displacement motion data and the rotation motion data corresponding to the animation object are data which perform relative motion with respect to the parent hierarchy. For example, the displacement of the left arm is (68, -30) in millimeters and the rotation angle is-30, meaning that the left arm is translated 68 millimeters along the X-axis, -30 millimeters along the Y-axis, and-30 degrees on the torso.

Step S204, acquiring the current key frame to be processed, and acquiring the forward adjacent key frame and the backward adjacent key frame of the current key frame to be processed in the current transformation dimension.

Specifically, the forward adjacent key frame refers to a key frame before the current key frame to be processed in the current transformation dimension, and the backward adjacent key frame refers to a key frame after the current key frame to be processed in the current transformation dimension. The original key frame data set comprises a plurality of key frames, and the key frames in the original key frame data set can be sequentially used as current key frames to be processed according to the sequence of the key frames. In some embodiments, the first key frame and the last key frame may not be considered as current pending key frames, since the first key frame has no forward neighboring key frame and the last key frame has no backward neighboring key frame.

Step S206, acquiring first motion data of the forward adjacent key frame in the current transformation dimension, and acquiring second motion data of the backward adjacent key frame in the current transformation dimension.

Specifically, after a current key frame to be processed, a forward adjacent key frame and a backward adjacent key frame of the current key frame to be processed are obtained, motion data of the forward adjacent key frame and the backward adjacent key frame in a current transformation dimension are obtained from an original key frame data set, the motion data of the forward adjacent key frame in the current transformation dimension are used as first motion data, and the motion data of the backward adjacent key frame in the current transformation dimension are used as second motion data.

Step S208, obtaining the current motion data of the current to-be-processed key frame in the current transformation dimension, and comparing the current motion data with the first motion data and the second motion data respectively to obtain a current comparison result.

Specifically, the alignment results may include agreement or disagreement. The criterion of whether to be consistent may be set as required, for example, the criterion may be completely the same as the criterion of consistency, or the criterion may be consistent when the difference is smaller than a certain threshold. For example, in a unity game engine, the motion data is generally reserved to 9 bits after decimal point by default, but the animation precision can reach the required precision after the motion data is reserved to 3 bits after decimal point through demonstration. Therefore, if the integer of the motion data is the same as the first 3 decimal places after the decimal place, it can be determined that the motion data is identical. And after the first motion data and the second motion data are obtained, comparing the current motion data with the first motion data to obtain a first comparison result, and comparing the current motion data with the second motion data to obtain a second comparison result. And then the first comparison result and the second comparison result are integrated to obtain the current comparison result. In one embodiment, the current comparison result is consistent when the first comparison result is consistent and the second comparison result is consistent. When either or both of the first comparison result and the second comparison result are inconsistent, the current comparison result is inconsistent.

In one embodiment, the motion data may be reduced before being compared. For example, data of 3 bits after the decimal point of the motion data is retained.

And step S210, deleting the current motion data according to the current comparison result.

Specifically, after the current comparison result is obtained, whether the current motion data is deleted is determined according to the current comparison result. And if the current comparison result is consistent, deleting the current motion data. And if the current comparison result is inconsistent, keeping the current motion data.

For example, as shown in fig. 4A, the abscissa represents the playing time of the animation, the ordinate represents the displacement motion value, the transformation dimension is the displacement motion data in the X-axis direction, and a1 to a4 are key frames as an example. As shown in fig. 4A, when the current to-be-processed key frame is a2, the motion data of a2 and the forward neighboring key frame a1 in the current transformation dimension are inconsistent, and the motion data of a2 and the backward neighboring key frame a3 in the current transformation dimension are consistent, so that the current comparison result of a2 is inconsistent, and the motion data of a2 key frame in the current transformation dimension is retained. When the current key frame to be processed is a3, the motion data of a3 and the forward adjacent key frame a2 in the current transformation dimension are consistent, and the motion data of a3 and the backward adjacent key frame a4 in the current transformation dimension are consistent, so that the current comparison result of a3 is consistent, and the motion data of a3 key frame in the current transformation dimension are deleted.

Step S212, the step of obtaining the current key frame to be processed is returned until the key frame to be processed in the original key frame data set is processed, and the current key frame data set is obtained.

Specifically, the original key frame data set may include a plurality of to-be-processed key frames, and if the to-be-processed key frames are not processed completely, the step of obtaining the current to-be-processed key frame is returned, the next to-be-processed key frame is obtained as the current to-be-processed key frame, and steps S204 to S210 are repeated. And obtaining the current key frame data set until the key frame to be processed in the original key frame data set is processed. For example, taking fig. 4A as an example, the key frames of the original key frame data set are a 1-a 4, wherein the middle key frames a2 and a3 are to-be-processed key frames, and first, a2 is used as the current to-be-processed key frame, and steps S204-S210 are performed, and since the current comparison result corresponding to a2 is inconsistent, the motion data of a2 in the current transformation dimension is retained. Then, the a3 is used as the current key frame to be processed, and the steps S204 to S210 are executed, because the current comparison result corresponding to the a3 is consistent. Therefore, the motion data of a3 in the current transformation dimension is deleted from the original key frame data set, and the current key frame data set is obtained.

Step S214, obtaining a current motion type corresponding to the current transformation dimension, and deleting current dimension motion data according to the current motion type, wherein the current dimension motion data is motion data of each key frame in the current key frame data set in the current transformation dimension.

Specifically, the motion types may include a displacement motion type, a rotation motion type, and a zoom motion type. And after the current key frame data set is obtained, determining whether to delete the motion data of each key frame in the current key frame data set in the current transformation dimension according to the current motion type by taking the motion type corresponding to the current transformation dimension as the current motion type, namely determining whether to delete the motion data of the current dimension according to the current motion type.

In some embodiments, if the motion data of the current keyframe data set in the current transformation dimension includes motion data of three or more keyframes, it indicates that there is motion data of a keyframe in the current transformation dimension that is different from the motion data of the forward neighboring keyframe or the backward neighboring keyframe. The motion data for each key frame in the current set of key frame data in the current transform dimension is not deleted. For example, in fig. 4A, after the motion data of the a3 key frame in the current transformation dimension is deleted, the motion data of the current transformation dimension further includes the motion data of three key frames, i.e., a1, a2 and a4, so that the motion data of three key frames, i.e., a1, a2 and a4, in the current transformation dimension is retained.

In one embodiment, the step of deleting the motion data of the current dimension according to the current motion type comprises: and when the current dimension motion data are only the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame of the current animation object, deleting the current dimension motion data corresponding to the first key frame and/or the current dimension motion data corresponding to the last key frame according to the current motion type.

Specifically, when the current dimensional motion data only includes the current dimensional motion data corresponding to the first key frame and the current dimensional motion data corresponding to the last key frame, that is, when the current dimensional motion data only includes the motion data of the first key frame and the motion data of the last key frame, it is necessary to determine whether to delete the current dimensional motion data corresponding to the first key frame and the current dimensional motion data corresponding to the last key frame according to the current motion type. For the skeleton animation, when the current motion type is a rotation motion type, current dimension motion data corresponding to a first key frame and current dimension motion data corresponding to a last key frame can be reserved, so that the current animation object is controlled to rotate according to the rotation motion data of the first key frame and the rotation motion data of the last key frame. When the current motion type is a displacement motion type, when the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame are both 0, it is indicated that the current animation object does not perform relative motion relative to the parent level in the current transformation dimension, so that the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame can be deleted. When the current motion type is a zooming motion type, if the current dimensional motion data corresponding to the first key frame and the current dimensional motion data corresponding to the last key frame are the same, that is, the zooming multiples are the same, the current dimensional motion data corresponding to the last key frame can be deleted, and the current dimensional motion data corresponding to the first key frame is retained, so that the animation object can be zoomed according to the zooming multiples of the first key frame. In the implementation of the present invention, taking an animation game as an example, because the data volume of animation data in the animation game is very large, after the current key data set is obtained, if the current dimensional motion data is only the current dimensional motion data corresponding to the first key frame and the current dimensional motion data corresponding to the last key frame of the current animation object, whether to delete the current dimensional motion data corresponding to the first key frame and/or the current dimensional motion data corresponding to the last key frame in the current key frame data set can be further determined according to the current motion type, so that the data volume of the animation data can be further reduced, the occupied memory during the running of the game application is small, and the speed during the running of the animation game application is improved.

According to the animation data processing method, the motion data of each key frame to be processed of the animation object can be compared with the motion data of the key frames adjacent in the front and back in the same transformation dimension according to the transformation dimension, the motion data of the key frames to be processed in the transformation dimension is deleted according to the current comparison result, the current key frame data set is obtained, the motion data of each key frame in the current key frame data set in the transformation dimension can be deleted according to the motion type of the transformation dimension, therefore, the invalid motion data of the key frames can be deleted, the occupation rate of computer resources is reduced while the animation precision is kept, and the operation speed of computer equipment is improved.

For example, as shown in fig. 4B, the left image is an animation image schematic diagram obtained by using the animation data processing method provided by the embodiment of the present invention, and the right image is an animation image schematic diagram obtained by using an animation data processing method in the prior art.

In one embodiment, the animation data processing method may further include: and when the current motion type is the rotary motion type, skipping the step of acquiring the current motion type corresponding to the current conversion dimension and deleting the current dimension motion data according to the current motion type. I.e. when it is rotational motion data, step S214 is not executed after the current key frame data set is obtained.

In one embodiment, the animation data processing method may further include: and determining whether the current animation object is in a white list, and when the current animation object is in the white list, skipping the step of acquiring the current motion type corresponding to the current transformation dimension and deleting the motion data of the current dimension according to the current motion type.

Specifically, the animation objects in the white list may be preset, and may be specifically set according to actual needs. For example, the animated objects in the whitelist may include the left upper arm and the left leg. And if the current animation object is in the white list, skipping the step of acquiring the current motion type corresponding to the current transformation dimension and deleting the motion data of the current dimension according to the current motion type. That is, after the current key frame data set is obtained, step S214 is not executed.

In an embodiment, as shown in fig. 5, step S214 is to obtain a current motion type corresponding to a current transform dimension, and the step of deleting the motion data of the current dimension according to the current motion type may specifically include the following steps:

step S502, when the current motion type is a displacement motion type, determining the relative displacement state of the current animation object according to the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame.

Specifically, the first key frame refers to the first key frame, and the last key frame refers to the last key frame. When the current motion type is a displacement motion type, the current transformation dimension may be a dimension corresponding to movement in an X-axis direction, a Y-axis direction, or a Z-axis direction. The displacement state may be a stationary state or a moving state. The displacement state may include a relative displacement state as well as an absolute displacement state. Relative displacement state refers to a displacement state relative to a parent hierarchy. When the relative displacement state is a relatively stationary state, it means that the current animation object is stationary with respect to the animation object of the parent hierarchy, and if the animation object of the parent hierarchy is moving, the current animation object is also moving as the animation object of the parent hierarchy, so that the current animation object is stationary with respect to the animation object of the parent hierarchy. The relative displacement state of the current animation object can be determined according to the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame. If the displacement motion value of the current dimension motion data corresponding to the first key frame is 0 and the curvature of the corresponding displacement curve is 0, the displacement motion value of the current dimension motion data corresponding to the last key frame is 0 and the curvature of the corresponding displacement curve is 0, and the relative displacement state of the current animation object is a static state.

In step S504, when the relative displacement state is a static state, the current dimensional motion data corresponding to the first key frame and the current dimensional motion data corresponding to the last key frame are deleted.

Specifically, when the relative displacement state is a static state, it indicates that the current animation object does not move in the current transformation dimension relative to the animation object of the parent level, and therefore, the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame may be deleted.

In an embodiment, as shown in fig. 6, step S214 is to obtain a current motion type corresponding to a current transform dimension, and deleting the current dimension motion data according to the current motion type may specifically include the following steps:

step S602, when the current motion type is a zoom motion type, determining a relative zoom state of the current animation object according to the current dimension motion data corresponding to the first key frame and the current dimension motion data corresponding to the last key frame.

In particular, zooming may include zooming out or zooming in. The zoom state includes no zoom or zoom. The zoom state may include a relative zoom state, which refers to a zoom state of a key frame of the current animation object from the head key frame to the tail key frame with respect to the head key frame, and an absolute zoom state, which refers to a zoom state with respect to the original current animation object. For example, if the scaling value of the first key frame is 2, the curvature of the corresponding scaling curve is 0, the scaling value of the last key frame is 2, and the curvature of the corresponding scaling curve is 0, the relative scaling state is a no scaling state, and the absolute scaling state is a scaling state because the current animation object is twice as large as the original current animation object.

Step S604, when the relative zoom state is no zoom, deleting the current dimensional motion data corresponding to the last key frame, and retaining the current dimensional motion data corresponding to the first key frame.

Specifically, when the relative scaling state is no scaling, it indicates that the current animation object is not scaled in the current transformation dimension relative to the animation object of the first key frame, so that the current dimension motion data corresponding to the last key frame may be deleted, and the current dimension motion data corresponding to the first key frame may be retained.

In one embodiment, as shown in fig. 7, the step of obtaining the first motion data of the forward neighboring key frame in the current transformation dimension and obtaining the second motion data of the backward neighboring key frame in the current transformation dimension at step S206 further includes:

step S702, acquiring the decimal number of the motion data of each key frame in the original key frame data set in the current transformation dimension.

Specifically, after the original key frame data set is obtained, the decimal place number of the motion data of the current transformation dimension is obtained. For example, if the motion data is 2.123456789 meters, the decimal place is 9 digits.

Step S704, when the decimal place number of the motion data of the current transformation dimension exceeds the decimal place number threshold, the motion data of the current transformation dimension is reduced to obtain reduced motion data.

In particular, the decimal place threshold may be set according to the accuracy requirement of the animation. For example, it has been demonstrated that the accuracy requirement of the game can be satisfied if the decimal place number is 3 digits in the standard unit, and therefore, the decimal place threshold value may be 3. When the simplification is performed, the simplification may be performed by using a rounding method, or may be performed by using a four-round six-into five-even method, which is not limited herein. The decimal digit of the simplified motion data is consistent with the decimal digit threshold. It can be understood that the current motion data, the first motion data, and the second motion data of the current to-be-processed keyframe in the current transformation dimension may be motion data obtained by reducing the motion data of the original keyframe data set.

The following describes an animation data processing method provided by an embodiment of the present invention, taking a game animation as an example, as shown in fig. 8, specifically including the following steps:

in step S802, animation motion data of the game is imported into the unity game animation engine. Suppose that the game animation data includes motion data of three types of motions of 4 key frames in displacement, rotation, and scaling. The displacement motion data may include motion data in three transformation dimensions, such as an X-axis direction, a Y-axis direction, and a Z-axis direction. The scaling motion data may include motion data in three transform dimensions, an X-axis direction, a Y-axis direction, and a Z-axis direction.

Step S804, the animation motion data of the game is simplified. And rounding off the reserved motion data decimal 3 bits to obtain the simplified motion data.

Step S806, acquiring the current key frame to be processed, and acquiring the forward adjacent key frame and the backward adjacent key frame of the current key frame to be processed. And when the first time of acquisition is carried out, the second key frame is taken as the current key frame to be processed according to the key frame sequence, and the first key frame and the third key frame are respectively the forward adjacent key frame and the backward adjacent key frame of the current key frame to be processed.

Step S808, acquiring first motion data of a forward adjacent key frame in the current transformation dimension, and acquiring second motion data of a backward adjacent key frame in the current transformation dimension. The next motion direction in the displacement, rotation and scaling motion types can be used as the current transformation dimension, and the data of each current transformation dimension is processed respectively. Taking the zoom motion data on the Y axis as the motion data of the current transformation dimension as an example, the zoom motion data of the first key frame on the Y axis is the first motion data, the zoom motion data of the third key frame on the Y axis is the second motion data,

step S810, obtaining current motion data of the current to-be-processed key frame in the current transformation dimension, and comparing the current motion data with the first motion data and the second motion data respectively to obtain a current comparison result. The zoom motion data of the second key frame on the Y axis is compared with the zoom motion data of the first key frame on the Y axis and the zoom motion data of the third key frame on the Y axis, and if the zoom motion data of the second key frame on the Y axis is the same as the zoom motion data of the first key frame on the Y axis, the zoom motion data of the second key frame on the Y axis is the same as the zoom motion data of the third key frame on the Y axis, so the comparison results are consistent.

And step S812, deleting the current motion data according to the current comparison result. And deleting the zooming motion data of the second key frame on the Y axis to obtain a current key frame data set because the comparison result is consistent.

Step S814, determining whether the processing of the to-be-processed key frame of the current dimension conversion is completed, if yes, entering step S816, and if not, returning to step S806. Since two pending key frames are included: the second key frame and the third key frame, so it is necessary to return to step S806. And taking the third key frame as the current key frame to be processed, wherein the forward adjacent key frame of the third key frame in the current transformation dimension is the first key frame and the backward adjacent key frame is the fourth key frame because the zooming motion data of the second key frame on the Y axis is deleted. It is assumed that the zoom motion data of the third key frame in the Y-axis is the same as the zoom motion data of the first key frame and the zoom motion data of the fourth key frame, and therefore, the zoom motion data of the third key frame in the Y-axis can be deleted.

Step S816, obtaining a current motion type corresponding to the current transform dimension, and deleting the current dimension motion data according to the current motion type. For the zooming motion data in the Y-axis direction, the current key frame data set includes the motion data of the first key frame and the motion data of the fourth key frame, and it is assumed that the zooming motion data of the first key frame in the Y-axis direction is the same as the zooming motion data of the fourth key frame in the Y-axis direction, so the zooming motion data of the fourth key frame in the Y-axis direction can be deleted, and the zooming motion data of the first key frame in the Y-axis direction is retained.
