Detailed Description

template<typename TValueType>
class kanzi::KeyframeAnimation< TValueType >::BezierKeyframe

Use bezier keyframes to animate property value along a bezier curve.

A Bezier keyframe consists of two control points in addition to a keyframe value for the animated property. A control point is a pair of a floating point numbers stored in Vector2:

  • The X coordinate of a control point specifies the animation time of that control point. The value of the control point is defined in relative units, where 0.0 corresponds to the time of the previous keyframe and 1.0 corresponds to the time of the current keyframe.
  • The Y coordinate of a control point specifies the value of the animated property of that control point. The value of the control point is defined in the same absolute units as the value of the keyframe.

Returns the first control point of the keyframe.

Returns
The first control point of the keyframe.
template<typename TValueType >
void kanzi::KeyframeAnimation< TValueType >::BezierKeyframe::setControlPoint0 ( Vector2  controlPoint)
inline

Sets the first control point for a keyframe.

Parameters
controlPointA control point that you want to use as the first control point of the keyframe.
template<typename TValueType >
Vector2 kanzi::KeyframeAnimation< TValueType >::BezierKeyframe::getControlPoint1 ( ) const
inline

Returns the second control point of the keyframe.

Returns
The second control point of the keyframe.

float  normalizedTime 
)
inlineoverridevirtual

Returns the value for the animated property at a given time.

Parameters
currentValueThe current value of the animated property.
normalizedTimeThe time at which you want to get the value of the animated property. 0.0 corresponds to the time of the previous keyframe. 1.0 corresponds to the time of this keyframe.
Returns
The value of the animated property at a given time.
