Transition¶
struct Transition
Create an animation transition function using * a one-dimensional cubic bezier curve.
This use the exact same algorithm as in CSS. The first and last control points of the cubic bezier curve are fixed to (0,0) and (1,1) respectively.
Variables¶
| Name | Description |
|---|---|
| m_controlPoints | The control points. |
Functions¶
| Name | Description |
|---|---|
| Transition | Constructs a new Transition curve. |
| Transition | Constructs a new Transition curve. |
| Ease | Given an animation duration percentage (in the range [0, 1]), * it calculates the animation progression percentage from the configured curve. |
Variable Details¶
m_controlPoints¶
BeizerCurveControlPoints m_controlPoints
The control points.
