While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a schematic flow diagram of a custom animation curve generation method according to an embodiment of the present invention, and as shown in fig. 1, the custom animation curve generation method includes the following steps:
That is to say, the start-stop time period and the key frame information of the animation curve to be generated are firstly obtained, then the start-stop time period of the animation curve to be generated is split into a plurality of key frames according to the time point corresponding to each key frame in the key frame information, and in addition, each key frame in the plurality of key frames has a corresponding state value.
It should be noted that the key frame refers to a first frame at the beginning of a certain animation curve to be generated within a start-stop time period of the animation curve to be generated; the starting and stopping time period of the animation curve to be generated is the duration of the animation curve to be generated, which is input by a user and comprises a starting time point and an ending time point; the key frame information comprises a plurality of key frames which are input by a user and positioned at corresponding time points in the starting and stopping time period of the animation curve to be generated and a state value corresponding to each key frame; the state value may be a change state value of the length, width, height, displacement, transparency and other effects of the object to be animated, which is input by the user, and the object to be animated may be information such as an image and characters, which is input by the user.
As an example, it is assumed that the obtained starting and stopping time period of the animation curve to be generated is 12S, and the key frame information is 0S or 1; 3S, 1; 6S, 0.5,9S, 1; 12S, 1; then, according to the obtained key frame information, a key frame can be inserted in the 3 rd S between the starting time period and the ending time period of 0-12S, and the amplification of an object to be subjected to animation processing at the moment is 1 time of that of the previous key frame; inserting a key frame in the 6 th S between the starting time period and the stopping time period of 0-12S, wherein the object to be animated at the moment is reduced to the last key frame, namely 0.5 time of the object to be animated in the 3 th S; and inserting a key frame in the 9 th S between the start-stop time periods 0-12S, amplifying the object to be subjected to animation processing at the moment to be 0.5 times of the previous key frame, namely 6S, and so on, splitting the animation process into a plurality of key frames to enable each key frame to bear the state value at a certain moment.
102, obtaining an interpolation algorithm corresponding to each two adjacent key frames, and generating an animation curve corresponding to each two adjacent key frames according to the interpolation algorithm.
It should be noted that, a plurality of interpolation algorithms are preset, and a corresponding animation curve is generated according to the interpolation algorithm corresponding to each two adjacent key frames input by the user.
As an example, firstly, obtaining an interpolation algorithm corresponding to every two adjacent key frames, wherein the interpolation algorithm corresponds to an adjustable parameter; then obtaining a parameter value corresponding to each adjustable parameter of the interpolation algorithm, and adjusting the corresponding adjustable parameter according to the parameter value to obtain an animation value corresponding to each two adjacent key frames; and then generating an animation curve corresponding to each two adjacent key frames according to the corresponding animation value between each two adjacent key frames.
It should be noted that the interpolation algorithm may be any one of a cubic curve interpolation algorithm and a spherical interpolation algorithm, where the cubic curve interpolation algorithm uses a third-order bezier curve to process, and the spherical interpolation algorithm uses a quaternion slerp to process.
That is to say, in the process of generating animation, the animation curve can be configured, and the corresponding animation curve between adjacent key frames can be generated by using an interpolation algorithm between the adjacent key frames, wherein different difference algorithms can be used between different key frames, so that the animation is richer, and the animation curve can be customized according to the user preference, thereby solving the problem of single solidification of the animation.
And 103, splicing the animation curves between every two adjacent key frames to obtain a complete animation curve.
It should be noted that after a complete animation curve is obtained, when a user needs to customize an animation, a corresponding animation value can be obtained from the generated animation curve according to a time point to complete the animation.
