202 Module Documentation 4.34 Direct3D 9 Interoperability Modules • Direct3D 9 Interoperability [DEPRECATED] Functions • CUresult cuD3D9CtxCreate (CUcontext ∗pCtx, CUdevice ∗pCudaDevice, unsigned int Flags, IDirect3DDevice9 ∗pD3DDevice) Create a CUDA context for interoperability with Direct3D 9. • CUresult cuD3D9GetDevice (CUdevice ∗pCudaDevice, const char ∗pszAdapterName) Gets the CUDA device corresponding to a display adapter. • CUresult cuGraphicsD3D9RegisterResource (CUgraphicsResource ∗pCudaResource, IDirect3DResource9 ∗pD3DResource, unsigned int Flags) Register a Direct3D 9 resource for access by CUDA. 4.34.1 Detailed Description This section describes the Direct3D 9 interoperability functions of the low-level CUDA driver application programming interface. 4.34.2 Function Documentation 4.34.2.1 cuD3D9CtxCreate (CUcontext ∗ pCtx, CUdevice ∗ pCudaDevice, unsigned int Flags, IDirect3DDevice9 ∗ pD3DDevice) Creates a new CUDA context, enables interoperability for that context with the Direct3D device pD3DDevice, and associates the created CUDA context with the calling thread. The created CUcontext will be returned in ∗pCtx. Direct3D resources from this device may be registered and mapped through the lifetime of this CUDA context. If pCudaDevice is non-NULL then the CUdevice on which this CUDA context was created will be returned in ∗pCudaDevice. On success, this call will increase the internal reference count on pD3DDevice. This reference count will be decremented upon destruction of this context through cuCtxDestroy(). This context will cease to function if pD3DDevice is destroyed or encounters an error. 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 Generated for NVIDIA CUDA Library by Doxygen
4.34 Direct3D 9 Interoperability 203 Note: Note that this function may also return error codes from previous, asynchronous launches. See also: cuD3D9GetDevice, cuGraphicsD3D9RegisterResource 4.34.2.2 cuD3D9GetDevice (CUdevice ∗ pCudaDevice, const char ∗ pszAdapterName) Returns in ∗pCudaDevice the CUDA-compatible device corresponding to the adapter name pszAdapterName obtained from EnumDisplayDevices() or IDirect3D9::GetAdapterIdentifier(). If no device on the adapter with name pszAdapterName is CUDA-compatible, then the call will fail. Parameters: pCudaDevice - Returned CUDA device corresponding to pszAdapterName pszAdapterName - Adapter name to query for device Returns: Note: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_VALUE, CUDA_ERROR_UNKNOWN See also: Note that this function may also return error codes from previous, asynchronous launches. cuD3D9CtxCreate 4.34.2.3 cuGraphicsD3D9RegisterResource (CUgraphicsResource ∗ pCudaResource, IDirect3DResource9 ∗ pD3DResource, unsigned int Flags) Registers the Direct3D 9 resource pD3DResource for access by CUDA and returns a CUDA handle to pD3Dresource in pCudaResource. The handle returned in pCudaResource may be used to map and unmap this resource until it is unregistered. On success this call will increase the internal reference count on pD3DResource. This reference count will be decremented when this resource is unregistered through cuGraphicsUnregisterResource(). This call is potentially high-overhead and should not be called every frame in interactive applications. The type of pD3DResource must be one of the following. • IDirect3DVertexBuffer9: may be accessed through a device pointer • IDirect3DIndexBuffer9: may be accessed through a device pointer • IDirect3DSurface9: may be accessed through an array. Only stand-alone objects of type IDirect3DSurface9 may be explicitly shared. In particular, individual mipmap levels and faces of cube maps may not be registered directly. To access individual surfaces associated with a texture, one must register the base texture object. • IDirect3DBaseTexture9: individual surfaces on this texture may be accessed through an array.
