Example 1

According to an embodiment of the present invention, there is provided a method for generating an animation curve, and in this embodiment, the method for generating an animation curve may be applied to a hardware environment of a terminal 102 provided with an animation curve generation tool as shown in fig. 1. As shown in fig. 1, the terminal 102 may include, but is not limited to, one of the following: cell-phone, panel computer. When generating an animation curve, the animation curve generation tool of the terminal 102 may generate an animation curve of the target animation according to the start time and the end time of the target animation, the state value of the start key frame of the target animation, and the state value of the end key frame of the target animation.

According to an embodiment of the present invention, there is provided a method for generating an animation curve, as shown in fig. 2, the method including:

s202: acquiring the starting time and the ending time of the target animation, the state value of the starting key frame of the target animation and the state value of the ending key frame of the target animation;

s204: obtaining the state values of the target animation at all moments within the range from the starting moment to the ending moment according to the state values of the starting key frame and the ending key frame;

s206: generating an animation curve of the target animation according to the state values at all the moments;

s208: an animation curve is displayed in the screen.

It should be noted that the animation curve in the embodiment of the present invention may be a one-dimensional animation curve, or may also be a complex animation curve such as a two-dimensional animation curve and a three-dimensional animation curve, which is not limited in this embodiment of the present invention.

Under the above circumstances, according to the animation curve generation method provided by the embodiment of the present invention, in step S202, it is necessary to obtain the start time and the end time of the target animation, the state value of the start key frame of the target animation, and the state value of the end key frame of the target animation.

In the embodiment of the invention, the key frames refer to the first frame at which the target animation starts and the last frame at which the target animation ends; the starting time of the target animation is the time corresponding to the first frame at which the target animation starts; the ending time of the target animation refers to the time corresponding to the last frame of the ending of the target animation; the state values can be the length, width, height, transparency and the like of the object, for example, if the length, width, height and transparency of the object are changed by the target animation, the state values of the target animation are considered to be 4, which are the length, width, height and transparency of the object respectively; animation value, which is a state value v of each frame of target animation change and a value p (t, v) formed by animation frame time t; the animation curve is a curve composed of a series of animation values p (t, v) generated by using the state value v as an ordinate and the time t of each frame of the target animation as an abscissa t.

Alternatively, the animation curve generating device may receive the duration of the target animation input by the designer, and determine the starting time and the ending time of the target animation according to the duration of the target animation. For example, the duration of the target animation inputted by the designer is 5s, and the animation curve generating device may determine the start time of the target animation to be 0s and the end time of the target animation to be 5s based on the 5 s.

Alternatively, the state value of the start key frame of the target animation and the state value of the end key frame of the target animation may be input to the animation curve generation device by the designer, for example, if the designer wants to change the transparency of the picture a from opaque to transparent, the state value V of the start key frame of the target animation may be input₀1, the state value V of the termination key frame of the target animation₁Is 0.

Under the above circumstances, according to the animation curve generation method provided by the embodiment of the present invention, in step S204, the state values of the target animation at each time point within the range from the start time point to the end time point may be obtained according to the state value of the start key frame and the state value of the end key frame. Further, in step S206, an animation curve of the target animation is generated from the state values at the respective times.

In the embodiment of the present invention, after the start time and the end time of the target animation, the state value of the start key frame of the target animation, and the state value of the end key frame of the target animation are obtained, the state values of the target animation at each time within the range from the start time to the end time can be obtained according to the above parameters. For example, as shown in fig. 3, before step S204, the method further includes:

The normalization is a dimensionless processing means, so that the absolute value of the physical system value becomes a certain relative value relation, i.e. a dimensionless expression is transformed into a dimensionless expression and becomes a highlight. For example, in a range from 0s as the start time of the target animation to 5s as the end time of the target animation, the value obtained by normalizing the 3 rd second is 3/5-0.6.
