Public Function TryGetCumulativeDelta (coordinateSystem As SpatialCoordinateSystem) As SpatialManipulationDelta

Parameters

coordinateSystem: SpatialCoordinateSystem

The coordinate system in which to express the delta.

Returns

SpatialManipulationDelta

The delta.

Remarks

This motion is expressed in the specified coordinate system. If you want the path followed by the manipulation to represent translation through the world as the user walks around, specify an anchored or stationary coordinate system. If you want the path to stay relative to the user and ignore the user's translation, specify a locator-attached coordinate system.

This method will return null if the specified coordinate system cannot be located at the moment.
