create
Interpolator create (Path path)
Create an Interpolator for an arbitrary Path. The Path must begin at (0, 0) and end at (1, 1). The x-coordinate along the Path is the input value and the output is the y coordinate of the line at that point. This means that the Path must conform to a function y = f(x).
Path must not have gaps in the x direction and must not loop back on itself such that there can be two points sharing the same x coordinate. | Parameters | |
|---|---|
path | Path: the Path to use to make the line representing the Interpolator |
| Returns | |
|---|---|
Interpolator | the Interpolator representing the Path |
create
Interpolator create (float controlX1, float controlY1, float controlX2, float controlY2)
Create an Interpolator for a cubic Bezier curve. The end points (0, 0) and (1, 1) are assumed.
| Parameters | |
|---|---|
controlX1 | float: the x coordinate of the first control point of the cubic Bezier |
controlY1 | float: the y coordinate of the first control point of the cubic Bezier |
controlX2 | float: the x coordinate of the second control point of the cubic Bezier |
controlY2 | float: the y coordinate of the second control point of the cubic Bezier |
| Returns | |
|---|---|
Interpolator | the Interpolator representing the cubic Bezier curve |
create
Interpolator create (float controlX, float controlY)
Create an Interpolator for a quadratic Bezier curve. The end points (0, 0) and (1, 1) are assumed.
| Parameters | |
|---|---|
controlX | float: the x coordinate of the quadratic Bezier control point |
controlY | float: the y coordinate of the quadratic Bezier control point |
| Returns | |
|---|---|
Interpolator | the Interpolator representing the quadratic Bezier curve |
