Diligent::IRenderDeviceD3D12 struct
#include <Graphics/GraphicsEngineD3D12/interface/RenderDeviceD3D12.h>

Exposes Direct3D12-specific functionality of a render device.

Base classes

auto GetD3D12Device() -> ID3D12Device*METHOD() virtual: Returns ID3D12Device interface of the internal Direct3D12 device object.
auto GetNextFenceValue(Uint32 QueueIndex) -> Uint64 METHOD() virtual: Returns the fence value that will be signaled by the GPU command queue next.
auto GetCompletedFenceValue(Uint32 QueueIndex) -> Uint64 METHOD() virtual: Returns the last completed fence value for the given command queue.
auto IsFenceSignaled(Uint32 QueueIndex, Uint64 FenceValue) -> Bool METHOD() virtual: Checks if the fence value has been signaled by the GPU. True means that all associated work has been finished.
auto CreateTextureFromD3DResource(ID3D12Resource* pd3d12Texture, RESOURCE_STATE InitialState, ITexture** ppTexture) -> void METHOD() virtual: Creates a texture object from native d3d12 resource.
auto CreateBufferFromD3DResource(ID3D12Resource* pd3d12Buffer, const BufferDesc& BuffDesc, RESOURCE_STATE InitialState, IBuffer** ppBuffer) -> void METHOD() virtual: Creates a buffer object from native d3d12 resoruce.
auto CreateBLASFromD3DResource(ID3D12Resource* pd3d12BLAS, const BottomLevelASDesc& Desc, RESOURCE_STATE InitialState, IBottomLevelAS** ppBLAS) -> void METHOD() virtual: Creates a bottom-level AS object from native d3d12 resoruce.
auto CreateTLASFromD3DResource(ID3D12Resource* pd3d12TLAS, const TopLevelASDesc& Desc, RESOURCE_STATE InitialState, ITopLevelAS** ppTLAS) -> void METHOD() virtual: Creates a top-level AS object from native d3d12 resoruce.

Returns ID3D12Device interface of the internal Direct3D12 device object.

The method does NOT call AddRef() on the returned interface, so Release() must not be called.

Creates a texture object from native d3d12 resource.

Parameters
pd3d12Texture in	- pointer to the native D3D12 texture
InitialState in	- Initial texture state. See Diligent::RESOURCE_STATE.
ppTexture out	- Address of the memory location where the pointer to the texture interface will be stored. The function calls AddRef(), so that the new object will contain one reference.

Creates a buffer object from native d3d12 resoruce.

Parameters
pd3d12Buffer in	- Pointer to the native d3d12 buffer resource
BuffDesc in	- Buffer description. The system can recover buffer size, but the rest of the fields need to be populated by the client as they cannot be recovered from d3d12 resource description
InitialState in	- Initial buffer state. See Diligent::RESOURCE_STATE.
ppBuffer out	- Address of the memory location where the pointer to the buffer interface will be stored. The function calls AddRef(), so that the new object will contain one reference.

Creates a bottom-level AS object from native d3d12 resoruce.

Parameters
pd3d12BLAS in	- Pointer to the native d3d12 acceleration structure resource
Desc in	- Bottom-level AS description.
InitialState in	- Initial BLAS state. Can be RESOURCE_STATE_UNKNOWN, RESOURCE_STATE_BUILD_AS_READ, RESOURCE_STATE_BUILD_AS_WRITE. See Diligent::RESOURCE_STATE.
ppBLAS out	- Address of the memory location where the pointer to the bottom-level AS interface will be stored. The function calls AddRef(), so that the new object will contain one reference.

Creates a top-level AS object from native d3d12 resoruce.

Parameters
pd3d12TLAS in	- Pointer to the native d3d12 acceleration structure resource
Desc in	- Top-level AS description.
InitialState in	- Initial TLAS state. Can be RESOURCE_STATE_UNKNOWN, RESOURCE_STATE_BUILD_AS_READ, RESOURCE_STATE_BUILD_AS_WRITE, RESOURCE_STATE_RAY_TRACING. See Diligent::RESOURCE_STATE.
ppTLAS out	- Address of the memory location where the pointer to the top-level AS interface will be stored. The function calls AddRef(), so that the new object will contain one reference.
