6.9.1. Direct3D 11 Interoperability [DEPRECATED]

This section describes deprecated Direct3D 11 interoperability functionality.

Functions

CUresult cuD3D11CtxCreate(CUcontext *pCtx, CUdevice *pCudaDevice, unsigned int Flags, ID3D11Device *pD3DDevice)

Create a CUDA context for interoperability with Direct3D 11.

CUresult cuD3D11CtxCreateOnDevice(CUcontext *pCtx, unsigned int flags, ID3D11Device *pD3DDevice, CUdevice cudaDevice)

Create a CUDA context for interoperability with Direct3D 11.

CUresult cuD3D11GetDirect3DDevice(ID3D11Device **ppD3DDevice)

Get the Direct3D 11 device against which the current CUDA context was created.

6.9.1.1. Functions

CUresult cuD3D11CtxCreate(CUcontext *pCtx, CUdevice *pCudaDevice, unsigned int Flags, ID3D11Device *pD3DDevice)

Create a CUDA context for interoperability with Direct3D 11.

Deprecated:

This function is deprecated as of CUDA 5.0.

This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA context with a D3D11 device in order to achieve maximum interoperability performance.

See also

cuD3D11GetDevice, cuGraphicsD3D11RegisterResource

Note

Note that this function may also return error codes from previous, asynchronous launches.

Parameters

  • pCtx – - Returned newly created CUDA context

  • pCudaDevice – - Returned pointer to the device on which the context was created

  • Flags – - Context creation flags (see cuCtxCreate() for details)

  • pD3DDevice – - Direct3D device to create interoperability context with

Returns

CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN

CUresult cuD3D11CtxCreateOnDevice(CUcontext *pCtx, unsigned int flags, ID3D11Device *pD3DDevice, CUdevice cudaDevice)
