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 a 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.

| Windows version | SDK version | Value added |
|---|---|---|
| 1809 | 17763 | AcquireBufferToUpdateContentWithHardwareProtection |
| 1809 | 17763 | CanAcquireWithHardwareProtection |
Properties
| CanAcquireWithHardwareProtection |
Gets whether hardware content protection is supported for this quad layer. |
Methods
| AcquireBufferToUpdateContent() |
Gets a Direct3D 11 back buffer whose contents will be displayed for this quad layer from this frame forward. |
| AcquireBufferToUpdateContentWithHardwareProtection() |
Gets a hardware-protected Direct3D 11 back buffer whose contents will be displayed for this quad layer from this frame forward. |
| UpdateContentProtectionEnabled(Boolean) |
Updates whether this quad layer contains protected content. |
| UpdateExtents(Vector2) |
Updates the extents of this quad layer in world coordinates. |
| UpdateLocationWithDisplayRelativeMode(Vector3, Quaternion) |
Updates the center location of this quad layer relative to the center of the displays, setting it to remain at that display-relative location in future frames. |
| UpdateLocationWithStationaryMode(SpatialCoordinateSystem, Vector3, Quaternion) |
Updates the center location of this quad layer in the world, setting it to remain at that world location in future frames. |
| UpdateViewport(Rect) |
Updates the viewport rectangle within the quad layer's texture that will be displayed to the screen. |
