IInertiaProcessor::DesiredExpansionDeceleration property

The DesiredExpansionDeceleration property specifies the rate at which the object will stop expanding.

This property is read/write.

Syntax


HRESULT put_DesiredExpansionDeceleration(
  [in]   FLOAT deceleration
);

HRESULT get_DesiredExpansionDeceleration(
  [out]  FLOAT *deceleration
);

Property value

The rate at which the object will stop expanding.

Error codes

Returns S_OK on success; otherwise, returns an error code such as E_FAIL.

Remarks

DesiredExpansionDeceleration and DesiredExpansion are mutually exclusive. If one is set, the other should be NaN.

If inertia processing has already started, setting DesiredExpansionDeceleration will reset the inertia engine to the initial state with new deceleration value applied.

Call this function to set the 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.
