Public Function GetQuadLayerUpdateParameters (layer As HolographicQuadLayer) As HolographicQuadLayerUpdateParameters

Parameters

layer: HolographicQuadLayer

The quad layer to update.

Returns

HolographicQuadLayerUpdateParameters

The update parameters.

Windows requirements

Device family	Windows 10 Fall Creators Update (introduced in 10.0.16299.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v5.0)

Remarks

To display quad layers, an application creates the necessary HolographicQuadLayer instances and adds them to a HolographicCamera's mutable QuadLayers list. To synchronize a retained quad layer update with a given immediate-mode holographic frame, an application requests an HolographicQuadLayerUpdateParameters instance from that frame by calling HolographicFrame.GetQuadLayerUpdateParameters. Any updates requested on that HolographicQuadLayerUpdateParameters instance will apply starting in that frame.

Note

The AcquireBufferToUpdateContent or AcquireBufferToUpdateContentWithHardwareProtection method must be called when updating a HolographicQuadLayer object for the first time.
