IHolographicQuadLayerUpdateParametersInterop interface (windows.graphics.holographic.interop.h)

The IHolographicQuadLayerUpdateParametersInterop interface is a nano-COM interface, used to commit Direct3D 12 buffer resources for quad layer rendering in the corresponding HolographicFrame.

The interface allows COM interop with the HolographicQuadLayerUpdateParameters class for applications that use Direct3D 12 for holographic rendering. Nano-COM allows Direct3D 12 objects to be used directly as parameters for API calls, rather than going through a container object.

Inheritance

The IHolographicQuadLayerUpdateParametersInterop interface inherits from the IInspectable interface.

Methods

The IHolographicQuadLayerUpdateParametersInterop interface has these methods.

Remarks

To use this interface in C++/WinRT, retrieve the HolographicQuadLayerUpdateParameters object from the HolographicFrame, and then QueryInterface for the IHolographicQuadLayerUpdateParametersInterop interface.

auto quadLayerParameters{ holographicFrame.GetQuadLayerUpdateParameters(m_quadLayer) };
winrt::com_ptr<IHolographicQuadLayerUpdateParametersInterop> quadLayerParametersInterop{
    quadLayerParameters.as<IHolographicQuadLayerUpdateParametersInterop>() };

To use this interface in C++/CX, first cast the HolographicQuadLayerUpdateParameters object (after retrieving it from the HolographicFrame) to IInspectable*. Then QueryInterface for the IHolographicQuadLayerUpdateParametersInterop interface from the IInspectable pointer.

auto quadLayerParameters = holographicFrame->GetQuadLayerUpdateParameters(m_quadLayer);
Microsoft::WRL::ComPtr<IHolographicQuadLayerUpdateParametersInterop> quadLayerParametersInterop;
{
    Microsoft::WRL::ComPtr<IInspectable> iInspectable = reinterpret_cast<IInspectable*>(quadLayerParameters);
    DX::ThrowIfFailed(iInspectable.As(&quadLayerParamsInterop));
}
