IUIAnimationTransitionLibrary2::CreateSinusoidalTransitionFromVelocity method

Creates a sinusoidal scalar transition where amplitude is determined by initial velocity.

Syntax

C++


HRESULT CreateSinusoidalTransitionFromVelocity(
  [in]  UI_ANIMATION_SECONDS    duration,
  [in]  UI_ANIMATION_SECONDS    period,
  [out] IUIAnimationTransition2 **transition
);

Parameters

duration [in]: The duration of the transition.
period [in]: The period of oscillation of the sinusoidal wave.
transition [out]: The new sinusoidal-velocity transition.

Return value

If this 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 following figure shows the change in value over time of an animation variable during a sinusoidal-velocity transition.
