Detailed Description

Interface to the buffer object implemented in D3D12.

Member Function Documentation

◆ GetD3D12Buffer()

virtual ID3D12Resource* Diligent::IBufferD3D12::GetD3D12Buffer	(	size_t &	DataStartByteOffset,
		Uint32	ContextId
	)

pure virtual

Returns a pointer to the ID3D12Resource interface of the internal Direct3D12 object.

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

Parameters

[in]	DataStartByteOffset	- Offset from the beginning of the buffer to the start of the data. This parameter is required for dynamic buffers, which are suballocated in a dynamic upload heap
[in]	ContextId	- Id of the context within which address of the buffer is requested.

Implemented in Diligent::BufferD3D12Impl.

◆ SetD3D12ResourceState()

virtual void Diligent::IBufferD3D12::SetD3D12ResourceState ( D3D12_RESOURCE_STATES state )
