CreateParabolicTransitionFromAcceleration Method

IUIAnimationTransitionLibrary2::CreateParabolicTransitionFromAcceleration method

Creates a parabolic-acceleration scalar transition.

Syntax


HRESULT CreateParabolicTransitionFromAcceleration(
  [in]  DOUBLE                  finalValue,
  [in]  DOUBLE                  finalVelocity,
  [in]  DOUBLE                  acceleration,
  [out] IUIAnimationTransition2 **transition
);

Parameters

finalValue [in]

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

finalVelocity [in]

The velocity, in units/second, at the end of the transition.

acceleration [in]

The acceleration, in units/second², during the transition.

transition [out]

The new parabolic-acceleration 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

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 following figure shows the change in value over time of an animation variable during a parabolic-acceleration transition.
