There is always a question about the necessity of PPT animation and the sound of rationality. One of the main points of rebuttal is that PPT can achieve a lot of effects, 36 into animation, 22 emphasis, 36 exit animations, 26 path animations, a total of 198 animations, and they can be combined with each other to achieve different The effect, the number is simply not calculated.
In fact, there are four basic animation properties: transparency, rotation, scale, position.
[Keyword 1: Transparency]
Animation is a change in transparency, such as a change from 100% transparency to 0%, from 0% to 100%, and any change between values.
Corresponding to the PPT, there are some changes from the A object to the B object. Since the PPT does not have a tween animation like Flash (the 2016 PPT has already implemented some tween), you can use A to fade out and B to fade in, or it has a good effect. of.
1, (enter) fade out, generally called: fade in
2, (exit) fade out, generally called: fade out
Reminder: PPT animation is a process animation, Flash or AE is a keyframe animation (or tweened animation). For example, the following rotation, from 0 to 275, can not set an initial 0 like AE, and then set a final state of 275, the animation automatically tween. PPT can only add one [Dagonal], and the degree of rotation is set to 275. If necessary, when you rotate to 180, zoom in again, and you need to calculate it in time.
[Keyword 2: Rotation]
Animation is the change in the angle of rotation of the object, such as from 0° to 275° (clockwise) or from 45° to -90° (counterclockwise).
Corresponding to PPT, ie (emphasis) gyro
[Keyword 3: Proportion]
An animation is a change in the size of an object. For example, from the original size, to 50% of the size, or 200% of the size.
Corresponding to PPT, ie
(emphasis) zoom in/out
[Keyword four: location]
Animation is the movement of an object from position A to position B, which can be linear motion, curved motion, or other lines.
Corresponding to PPT, ie (action path) custom path
As for other animations in PPT, there are two categories.
1, can be obtained from the above four combinations
For example, (enter) flying in is the path animation;
(emphasis) the seesaw, that is, the rotation;
(exit) telescopic, which is fade out (transparency) + horizontal magnification (proportion)
2, special effects animation (can not be combined)
For example, (in and out) erasure, blinds and other basic animations
(exit) basic types such as blinds
In short, as long as you master the four attribute animations (corresponding to PPT, 5 animations: fade in, fade out, gyro, zoom in/out, custom path), you can master almost all PPT animations.
