C Specification

The XrGraphicsBindingD3D12KHR structure is defined as:

// Provided by XR_KHR_D3D12_enable
typedef struct XrGraphicsBindingD3D12KHR {
    XrStructureType        type;
    const void*            next;
    ID3D12Device*          device;
    ID3D12CommandQueue*    queue;
} XrGraphicsBindingD3D12KHR;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • device is a pointer to a valid ID3D12Device to use.

  • queue is a pointer to a valid ID3D12CommandQueue to use.

Description

To create a D3D12-backed XrSession, the application provides a pointer to an XrGraphicsBindingD3D12KHR structure in the XrSessionCreateInfo::next chain when calling xrCreateSession. The D3D12 device specified in XrGraphicsBindingD3D12KHR::device must be created in accordance with the requirements retrieved through xrGetD3D12GraphicsRequirementsKHR, otherwise xrCreateSession must return XR_ERROR_GRAPHICS_DEVICE_INVALID.

Creating a session using this structure triggers several requirements on the runtime regarding swapchain images. See the specification of XrSwapchainImageD3D12KHR for details.
