Function Documentation

◆ allocateSharedImages()

xrt_result_t xrt::auxiliary::d3d::d3d12::allocateSharedImages ( ID3D12Device &  device,
const xrt_swapchain_create_info &  xsci,
size_t  image_count,
std::vector< wil::com_ptr< ID3D12Resource > > &  out_images,
std::vector< wil::unique_handle > &  out_handles 
)

Allocate images (ID3D12Resource) that have a corresponding native handle.

Parameters
deviceA D3D12 device to allocate with.
xsciSwapchain create info: note that the format is assumed to be a DXGI_FORMAT (conversion to typeless is automatic)
image_countThe number of images to create.
keyed_mutexWhether to create images with a shared "keyed mutex" as well
[out]out_imagesA vector that will be cleared and populated with the images.
[out]out_handlesA vector that will be cleared and populated with the corresponding native handles.
Returns
xrt_result_t, one of:
