Automatic Animation
GeoGebra allows you to animate not only free numbers and/or angles at the same time, but also dependent points that are constrained on an object (segment, line, function, curve, etc.). In order to be automatically animated, free numbers / angles need to be shown as sliders in the Graphics View.
If you want to animate a free number or angle in GeoGebra, as well as a dependent point, you need to select Animation On in the Context Menu of that number, angle or point. In order to stop the animation, you need to un-check Animation On in the same context menu.
In the Properties Dialog on tab Slider you can change the behavior of the animation:
On the one hand, you may control the Speed of the animation.
On the other hand, you can decide how the animation cycle is repeated:
- ⇔ Oscillating
- The animation cycle alternates between Decreasing and Increasing.
- ⇒ Increasing
- The slider value is always increasing. After reaching the maximum value of the slider, it jumps back to the minimum value and continues the animation.
- ⇐ Decreasing
- The slider value is always decreasing. After reaching the minimum value of the slider, it jumps back to the maximum value and continues the animation.
- ⇒ Increasing (Once)
- The slider value is always increasing. After reaching the maximum value of the slider, it stops at this value and ends the animation.
Manual Animation
To manually change a number, angle or point position continuously, select the Move Tool. Then, click on a free number, angle or a dependent point and press either the + or – key or the arrow keys on you keyboard. Keeping one of these keys pressed allows you to produce manual animations.
Keyboard Shortcuts
- Shift + arrow key gives you a step width of 0.1 units
- Ctrl + arrow key gives you a step width of 10 units
- Alt + arrow key gives you a step width of 100 units
