IUIAnimationTransitionLibrary::CreateSinusoidalTransitionFromVelocity method (uianimation.h)

Creates a sinusoidal-velocity transition, with an amplitude determined by the initial velocity.

Syntax

HRESULT CreateSinusoidalTransitionFromVelocity(
  [in]  UI_ANIMATION_SECONDS   duration,
  [in]  UI_ANIMATION_SECONDS   period,
  [out] IUIAnimationTransition **transition
);

Parameters

[in] duration

The duration of the transition.

[in] period

The period of oscillation of the sinusoidal wave in seconds.

[out] transition

The new sinusoidal-velocity transition.

Return value

If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See Windows Animation Error Codes for a list of error codes.

Remarks

The value of the animation variable oscillates around the initial value over the entire duration of a sinusoidal-range transition. The amplitude of the oscillation is determined by the velocity when the transition begins.

The figure below shows the effect on an animation variable over time during a sinusoidal-velocity transition.
