The NormalEquation type defines a discriminated union used to specify the equation to use when generating values.
The basic cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| Linear *1 | Increase linearly from 0.0 to +1.0 (inclusive) |
| QuarterPipe | Resembles the lower-right quarter of a circle |
| HockeyStick | Resembles a hockey stick with the toe on the ground pointing to the left |
| SkiSlope | Flattens at the bottom, centre, and top |
| Bump | Looks like a bump |
| SineWave | Looks like part of a sine equation from 0.0 to 2*PI but 'raised' by 0.5 |
| CosineWave | Looks like part of a cosine equation from 0.0 to 2*PI but 'raised' by 0.5 |
The Sine cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseSineIn | Is a slow curve at the start tending to almost straight at the end (a bit like HockeyStick) |
| EaseSineOut | Is a curve which is almost straight at the start with a slow curve at the end (a bit like HockeyStick flipped diagonally) |
| EaseSineInOut | Is a curve which flattens at the bottom, centre, and top (a bit like SkiSlope) |
The Cubic cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseCubicIn | Is like EaseSineIn but with more curve |
| EaseCubicOut | Is like EaseSineOut with more curve |
| EaseCubicInOut | Is like EaseSineInOut but with more curve |
The Quint cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseQuintIn | Is like EaseCubicIn but with more curve |
| EaseQuintOut | Is like EaseCubicOut but with more curve |
| EaseQuintInOut | Is like EaseCubicInOut but with more curve |
The Circ cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseCircIn | Is a curve which resembles the lower-right quarter of a circle (a bit like QuarterPipe) |
| EaseCircOut | Is a curve which resembles the upper-left quarter of a circle (a bit like QuarterPipe flipped diagonally) |
| EaseCircInOut | Is a slow curve at the start tending to almost straight at the end (a bit like EaseQuintInOut but with more curve) |
The Quad cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseQuadIn | Is like EaseSineIn but with a little more curve |
| EaseQuadOut | Is like EaseSineOut but with a little more curve |
| EaseQuadInOut | Is like EaseSineInOut but with a little more curve |
The Quart cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseQuartIn | Is like EaseCubicIn but with more curve |
| EaseQuartOut | Is like EaseCubicOut but with more curve |
| EaseQuartInOut | Is like EaseCubicInOut but with more curve |
The Expo cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseExpoIn | Is like EaseQuartIn but with more curve |
| EaseExpoOut | Is like EaseQuartOut but with more curve |
| EaseExpoInOut | Is like EaseQuartInOut but with more curve |
The Bounce cases are:
| Case Name | Equation Produces Sequence Of Values Which |
|---|---|
| EaseBounceIn | Is a curve which performs progressively larger 'hops' until it reaches the maximum value |
| EaseBounceOut | Is a curve which performs progressively smaller 'upside-down hops' until it reaches the maximum value |
| EaseBounceInOut | Is a curve which looks like EaseBounceIn followed by EaseBounceOut |
- *1 : The default case.
To specify an equation simply supply its name, such as NormalEquation.Linear.
Functions are available for converting to and from POCO types and DU cases. See the overview documentation for more information about these.
Exception-free processing versions - FailSafe, Option, and Result - of some functions are available. See the overview documentation for more information about these.
