步骤101，获取待生成动画曲线的起止时间段和关键帧信息，并根据关键帧信息对待生成动画曲线的起止时间段进行分段处理以拆分成多个关键帧，其中，关键帧信息包括每个关键帧对应的时间和每个关键帧对应的状态值。Step 101: Obtain the start and end time periods and key frame information of the animation curve to be generated, and perform segmentation processing on the start and end time periods of the animation curve to be generated according to the key frame information to split into multiple key frames, wherein the key frame information includes each key frame. The time corresponding to each keyframe and the state value corresponding to each keyframe.
也就是说，首先获取待生成动画曲线的起止时间段和关键帧信息，然后根据关键帧信息中的每个关键帧对应的时间点将待生成动画曲线的起止时间段拆分成多个关键帧，另外，多个关键帧中的每个关键帧有其对应的状态值。That is to say, first obtain the start and end time period and key frame information of the animation curve to be generated, and then split the start and end time period of the animation curve to be generated into multiple key frames according to the time point corresponding to each key frame in the key frame information , and in addition, each keyframe in the plurality of keyframes has its corresponding state value.
需要说明的是，关键帧，是指位于待生成动画曲线的起止时间段内的某个待生成动画曲线开始的第一帧；待生成动画曲线的起止时间段，为用户输入的待生成动画曲线的持续时间，包括开始时间点和结束时间点；关键帧信息，为用户输入的包括位于待生成动画曲线的起止时间段内的对应时间点上的多个关键帧以及每个关键帧对应的状态值；状态值，可以为用户输入的待进行动画处理的对象的长度、宽度、高度、位移、透明度等效果的变化状态值，待进行动画处理的对象，可以为用户输入的图像、文字等信息。It should be noted that the key frame refers to the first frame of a certain animation curve to be generated within the start and end time period of the animation curve to be generated; the start and end time period of the animation curve to be generated is the animation curve to be generated input by the user.

作为一个示例，假设获取到的待生成动画曲线的起止时间段为12S、关键帧信息为0S、1；3S、1；6S，0.5,9S，1；12S，1；则，根据上述获取到的关键帧信息可在起止时间段0-12S之间的第3S***一个关键帧，且在该时刻待进行动画处理的对象放大为上一关键帧的1倍；在起止时间段0-12S之间的第6S***一个关键帧，且在该时刻待进行动画处理的对象为缩小为上一关键帧，即3S时的0.5倍；在起止时间段0-12S之间的第9S***一个关键帧，且在该时刻待进行动画处理的对象放大为上一关键帧，即6S时的0.5倍，以此类推，将动画过程拆分成多个关键帧，使每个关键帧承载着某个时刻的状态值。As an example, it is assumed that the obtained start and end time period of the animation curve to be generated is 12S, and the key frame information is 0S, 1; 3S, 1; 6S, 0.5, 9S, 1; 12S, 1; then, according to the above obtained The key frame information can insert a key frame in the 3S between the start and end time period 0-12S, and the object to be animated at this moment is enlarged to 1 times of the previous key frame; between the start and end time period 0-12S Insert a key frame in the 6S, and the object to be animated at this moment is reduced to the previous key frame, that is, 0.5 times when it is 3S; Insert a key frame in the 9S between the start and end time period 0-12S, And the object to be animated at this moment is enlarged to the previous key frame, that is, 0.5 times of the 6S time, and so on, the animation process is divided into multiple key frames, so that each key frame carries a certain moment.

作为一个示例，首先获取每两个相邻关键帧之间对应的插值算法，其中，插值算法中对应有可调的参数；接着获取插值算法的每个可调参数对应的参数值，并根据参数值对该对应的可调参数进行调整，以得到每两个相邻关键帧之间对应的动画值；然后根据每两个相邻关键帧之间对应的动画值生成每两个相邻关键帧之间对应的动画曲线。As an example, first obtain the corresponding interpolation algorithm between every two adjacent key frames, wherein the interpolation algorithm has corresponding adjustable parameters; then obtain the parameter value corresponding to each adjustable parameter of the interpolation algorithm, and according to the parameter The corresponding adjustable parameter is adjusted to obtain the corresponding animation value between every two adjacent keyframes; then each two adjacent keyframes are generated according to the corresponding animation value between every two adjacent keyframes The corresponding animation curve between them.
需要说明的是，上述插值算法可为三次曲线插值算法、球面插值算法中的任意一种，其中三次曲线插值算法采用三阶贝塞尔曲线进行处理，球面插值算法采用四元数slerp进行处理。It should be noted that the above-mentioned interpolation algorithm may be any one of a cubic curve interpolation algorithm and a spherical interpolation algorithm, wherein the cubic curve interpolation algorithm uses a third-order Bezier curve for processing, and the spherical interpolation algorithm uses a quaternion slerp for processing.
也就是说，在进行动画生成的过程中，可对动画曲线进行配置，通过在相邻关键帧之间使用插值算法以生成相邻关键帧之间对应的动画曲线，其中，不同关键帧之间可使用不同的差值算法，使得动画更加丰富，并可根据用户喜好进行自定义动画曲线，解决了动画固化单一的问题。That is to say, in the process of animation generation, the animation curve can be configured, by using an interpolation algorithm between adjacent keyframes to generate animation curves corresponding to adjacent keyframes, wherein, between different keyframes Different difference algorithms can be used to make the animation more abundant, and the animation curve can be customized according to user preferences, which solves the problem of single animation curing.
