The InitialRadius property specifies the distance from the edge of the target to its center before the object was changed.
This property is read/write.
HRESULT put_InitialRadius( [in] FLOAT radius ); HRESULT get_InitialRadius( [out] FLOAT *radius );
The initial distance from the edge of the target to its center.
Returns S_OK on success; otherwise, returns an error code such as E_FAIL.
If Inertia processing has already started, setting InitialRadius will reset the inertia engine to the initial state with new radius value applied.
Call this function to set initial state of inertia. You would call this function most likely during the ManipulationCompleted event of the IManipulationProcessor, or in the constructor of the IInertiaProcessor interface.
