CAAT.Interpolator
Interpolator object instances are used mainly in CAAT.Behavior objects to define the way they are applied.
The default interpolator applied to any Behavior is a linear ramp, that is, the Behavior is applied in regular time increments.
A CAAT.Interpolator object has the ability to modify this linearity, and apply Behaviors differently, in example accelerating, exponentially, etc. Despite the interpolator function being applied, the behavior will apply for the range of values it had defined.
In CAAT an interpolator is an object with a function getPosition( time ) which returns an object of the form {x: time, y: float}. The time parameter is a value between 0 and 1, meaning 0 behavior's start time and 1 behavior's start time + duration.
Interpolators have a function setPingPong() which modifies the time parameter. If this method is called, the interpolator will take half application time to go from start to end values, the other half to go from end to start values.
Here you can see the visual representation of every defined CAAT.Interpolator. The x axis means behavior application time, and the y axis means the resulting value time to apply the behavior for.
Linear Interpolator
Instance interpolators are created by calling new CAAT.Interpolator().createLinearInterpolator
| Pinpong=false | Pinpong=true |
Linear Inverse Interpolator
Instance interpolators are created by calling new CAAT.Interpolator().createLinearInterpolator
| Pinpong=false | Pinpong=true |
Exponential Interpolator
Instance interpolators are created by calling new CAAT.Interpolator().createExponentialInInterpolator or new CAAT.Interpolator().createExponentialOutInterpolator or new CAAT.Interpolator().createExponentialInOutInterpolator.
The exponential interpolator, accepts two parameters. The exponent of the Interpolator function and the previously described pingpong boolean value.
| Pinpong=false | |||
| Exponent | ExponentialIn | ExponentialOut | ExponentialInOut |
| 2 | |||
| 4 | |||
| 6 | |||
| Pinpong=true | |||
| Exponent | ExponentialIn | ExponentialOut | ExponentialInOut |
| 2 | |||
| 4 | |||
| 6 | |||
Bounce Interpolator
Instance interpolators are created by calling new CAAT.Interpolator().createBounceInInterpolator or new CAAT.Interpolator().createBounceOutInterpolator or new CAAT.Interpolator().createBounceInOutInterpolator.
| Pinpong=false | ||
| BounceIn | BounceOut | BounceInOut |
| Pinpong=true | ||
| BounceIn | BounceOut | BounceInOut |
Elastic Interpolator
Instance interpolators are created by calling new CAAT.Interpolator().createElasticInInterpolator or new CAAT.Interpolator().createElasticOutInterpolator or new CAAT.Interpolator().createElasticInOutInterpolator.
| Pinpong=false | |||
| Parameters | ElasticIn | ElasticOut | ElasticInOut |
| amp=1.1, liquid=.4 | |||
| amp=1.0, liquid=.2 | |||
| Pinpong=true | |||
| Parameters | ElasticIn | ElasticOut | ElasticInOut |
| amp=1.1, liquid=.4 | |||
| amp=1.0, liquid=.2 | |||
