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.
