IInertiaProcessor::get_DesiredExpansion method (manipulations.h)

The DesiredExpansion property specifies the desired change in the object's average radius.

This property is read/write.

Syntax

HRESULT get_DesiredExpansion(
  FLOAT *expansion
);

Parameters

expansion

Return value

None

Remarks

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

If inertia processing has already started, setting DesiredExpansion 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.
