ISpinEffect_KC Interface

ISpinEffect_KC interface provides access to spin effect, which implements animation of a fast rotation of an object

Spin effect can be queried form ISection inmplemented by the object to be animated

To implement the effect use Modelign Studio to create a Surface Of Revolution, which represents spinning state of the object and make it an invisible child of the orginal object. Obtain ISection of the object to be animated. Query ISpinEffect_KC from the ISection. Call ISpinEffect_KC.Setup() with objectSpan queried from the spinning state object. Call ISpinEffect_KC.Begin() / End to start / stop the animation.

The animated obejct has to be a top level one in the model. unless itis desired its parent to be span too

HRESULT Setup(ISection* objectSpan, IView* iView)

Parameters

objectSpan - [in] Spinning representation of the object

Remarks:

Associates a spinning representation of the object to be span. The representation obejct has to have considing local frame and its contour has to coinside with spinning contour of the initial object for the animation to be realistic.


HRESULT Begin(int durationMilliSeconds)

Parameters

durationMilliSeconds - [in] Duration of animation of spining start

Remarks:

The method will show the animated object starting and accelerating spinning. In the end of the period the animated object will be hidden and it spinning representation will be shown instead


HRESULT End(int durationMilliSeconds)

Parameters

durationMilliSeconds - [in] Duration of animation of spining end

Remarks:

The method will show actions of the Begin() method in reverse order: The spinning representation will hidden and the initial object will be shown spinning instead. The spinning will slow down and will stop in the end of the period
