4.19. Direct3D 11 Interoperability [DEPRECATED]
This section describes deprecated Direct3D 11 interoperability functions.
Functions
- __host__ cudaError_t cudaD3D11GetDirect3DDevice ( ID3D11Device** ppD3D11Device )
- Gets the Direct3D device against which the current CUDA context was created.
- __host__ cudaError_t cudaD3D11SetDirect3DDevice ( ID3D11Device* pD3D11Device, int device = -1 )
- Sets the Direct3D 11 device to use for interoperability with a CUDA device.
Functions
- __host__ cudaError_t cudaD3D11GetDirect3DDevice ( ID3D11Device** ppD3D11Device )
-
Gets the Direct3D device against which the current CUDA context was created.
Parameters
- ppD3D11Device
- - Returns the Direct3D device for this thread
Returns
Deprecated
This function is deprecated as of CUDA 5.0.
Description
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA device with a D3D11 device in order to achieve maximum interoperability performance.
Note:Note that this function may also return error codes from previous, asynchronous launches.
See also:
- __host__ cudaError_t cudaD3D11SetDirect3DDevice ( ID3D11Device* pD3D11Device, int device = -1 )
-
Sets the Direct3D 11 device to use for interoperability with a CUDA device.
Parameters
- pD3D11Device
- - Direct3D device to use for interoperability
- device
- - The CUDA device to use. This device must be among the devices returned when querying cudaD3D11DeviceListAll from cudaD3D11GetDevices, may be set to -1 to automatically select an appropriate CUDA device.
Returns
cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidValue, cudaErrorSetOnActiveProcess
