IUIAnimationTransitionLibrary::CreateParabolicTransitionFromAcceleration method (uianimation.h)

Creates a parabolic-acceleration transition.

Syntax

HRESULT CreateParabolicTransitionFromAcceleration(
  [in]  DOUBLE                 finalValue,
  [in]  DOUBLE                 finalVelocity,
  [in]  DOUBLE                 acceleration,
  [out] IUIAnimationTransition **transition
);

Parameters

[in] finalValue

The value of the animation variable at the end of the transition.

[in] finalVelocity

The velocity at the end of the transition.

[in] acceleration

The acceleration during the transition.

[out] transition

The new parabolic-acceleration 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

During a parabolic-acceleration transition, the value of the animation variable changes from the initial value to the final value ending at the specified velocity. You can control how quickly the variable reaches the final value by specifying the rate of acceleration.

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