Function Documentation
cudaError_t cudaD3D9MapResources (int count, IDirect3DResource9 ** ppResources)
Deprecated
This function is deprecated as of CUDA 3.0.
Maps the count Direct3D resources in ppResources for access by CUDA.
The resources in ppResources may be accessed in CUDA kernels until they are unmapped. Direct3D should not
access any resources while they are mapped by CUDA. If an application does so, the results are undefined.
This function provides the synchronization guarantee that any Direct3D calls issued before
cudaD3D9MapResources() will complete before any CUDA kernels issued after cudaD3D9MapResources() begin.
If any of ppResources have not been registered for use with CUDA or if ppResources contains any duplicate
entries then cudaErrorInvalidResourceHandle is returned. If any of ppResources are presently mapped for
access by CUDA then cudaErrorUnknown is returned.
Parameters:
count - Number of resources to map for CUDA
ppResources - Resources to map for CUDA
Returns:
cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

cudaGraphicsMapResources
cudaError_t cudaD3D9RegisterResource (IDirect3DResource9 * pResource, unsigned int flags)
Deprecated
This function is deprecated as of CUDA 3.0.
Registers the Direct3D resource pResource for access by CUDA.
If this call is successful, then the application will be able to map and unmap this resource until it is
unregistered through cudaD3D9UnregisterResource(). Also on success, this call will increase the internal
reference count on pResource. This reference count will be decremented when this resource is unregistered
through cudaD3D9UnregisterResource().
This call potentially has a high-overhead and should not be called every frame in interactive
applications.
The type of pResource must be one of the following.
• IDirect3DVertexBuffer9: No notes.
• IDirect3DIndexBuffer9: No notes.
• IDirect3DSurface9: 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: When a texture is registered, all surfaces associated with all mipmap levels of
all faces of the texture will be accessible to CUDA.
The flags argument specifies the mechanism through which CUDA will access the Direct3D resource. The
following value is allowed:
• cudaD3D9RegisterFlagsNone: Specifies that CUDA will access this resource through a void*. The pointer,
size, and pitch for each subresource of this resource may be queried through
cudaD3D9ResourceGetMappedPointer(), cudaD3D9ResourceGetMappedSize(), and
cudaD3D9ResourceGetMappedPitch() respectively. This option is valid for all resource types.
Not all Direct3D resources of the above types may be used for interoperability with CUDA. The following
are some limitations:
• The primary rendertarget may not be registered with CUDA.
• Resources allocated as shared may not be registered with CUDA.
• Any resources allocated in D3DPOOL_SYSTEMMEM or D3DPOOL_MANAGED may not be registered with CUDA.
• Textures which are not of a format which is 1, 2, or 4 channels of 8, 16, or 32-bit integer or
floating-point data cannot be shared.
• Surfaces of depth or stencil formats cannot be shared.
If Direct3D interoperability is not initialized on this context, then cudaErrorInvalidDevice is returned.
If pResource is of incorrect type (e.g, is a non-stand-alone IDirect3DSurface9) or is already registered,
then cudaErrorInvalidResourceHandle is returned. If pResource cannot be registered then cudaErrorUnknown
is returned.
Parameters:
pResource - Resource to register
flags - Parameters for resource registration
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

cudaError_t cudaD3D9ResourceGetMappedArray (cudaArray ** ppArray, IDirect3DResource9 * pResource, unsigned
int face, unsigned int level)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pArray an array through which the subresource of the mapped Direct3D resource pResource,
which corresponds to face and level may be accessed. The value set in pArray may change every time that
pResource is mapped.
If pResource is not registered then cudaErrorInvalidResourceHandle is returned. If pResource was not
registered with usage flags cudaD3D9RegisterFlagsArray, then cudaErrorInvalidResourceHandle is returned.
If pResource is not mapped, then cudaErrorUnknown is returned.
For usage requirements of face and level parameters, see cudaD3D9ResourceGetMappedPointer().
Parameters:
ppArray - Returned array corresponding to subresource
pResource - Mapped resource to access
face - Face of resource to access
level - Level of resource to access
Returns:
cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

cudaGraphicsSubResourceGetMappedArray
cudaError_t cudaD3D9ResourceGetMappedPitch (size_t * pPitch, size_t * pPitchSlice, IDirect3DResource9 *
pResource, unsigned int face, unsigned int level)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pPitch and *pPitchSlice the pitch and Z-slice pitch of the subresource of the mapped Direct3D
resource pResource, which corresponds to face and level. The values set in pPitch and pPitchSlice may
change every time that pResource is mapped.
The pitch and Z-slice pitch values may be used to compute the location of a sample on a surface as
follows.
For a 2D surface, the byte offset of the sample at position x, y from the base pointer of the surface is:
y * pitch + (bytes per pixel) * x
For a 3D surface, the byte offset of the sample at position x, y, z from the base pointer of the surface
is:
z* slicePitch + y * pitch + (bytes per pixel) * x
Both parameters pPitch and pPitchSlice are optional and may be set to NULL.
If pResource is not of type IDirect3DBaseTexture9 or one of its sub-types or if pResource has not been
registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned. If pResource was not
registered with usage flags cudaD3D9RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned.
If pResource is not mapped for access by CUDA then cudaErrorUnknown is returned.
For usage requirements of face and level parameters, see cudaD3D9ResourceGetMappedPointer().
Parameters:
pPitch - Returned pitch of subresource
pPitchSlice - Returned Z-slice pitch of subresource
pResource - Mapped resource to access
face - Face of resource to access
level - Level of resource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

cudaError_t cudaD3D9ResourceGetMappedPointer (void ** pPointer, IDirect3DResource9 * pResource, unsigned int
face, unsigned int level)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pPointer the base pointer of the subresource of the mapped Direct3D resource pResource, which
corresponds to face and level. The value set in pPointer may change every time that pResource is mapped.
If pResource is not registered, then cudaErrorInvalidResourceHandle is returned. If pResource was not
registered with usage flags cudaD3D9RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned.
If pResource is not mapped, then cudaErrorUnknown is returned.
If pResource is of type IDirect3DCubeTexture9, then face must one of the values enumerated by type
D3DCUBEMAP_FACES. For all other types, face must be 0. If face is invalid, then cudaErrorInvalidValue is
returned.
If pResource is of type IDirect3DBaseTexture9, then level must correspond to a valid mipmap level. Only
mipmap level 0 is supported for now. For all other types level must be 0. If level is invalid, then
cudaErrorInvalidValue is returned.
Parameters:
pPointer - Returned pointer corresponding to subresource
pResource - Mapped resource to access
face - Face of resource to access
level - Level of resource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

corresponds to face and level. The value set in pSize may change every time that pResource is mapped.
If pResource has not been registered for use with CUDA then cudaErrorInvalidResourceHandle is returned.
If pResource was not registered with usage flags cudaD3D9RegisterFlagsNone, then
cudaErrorInvalidResourceHandle is returned. If pResource is not mapped for access by CUDA then
cudaErrorUnknown is returned.
For usage requirements of face and level parameters, see cudaD3D9ResourceGetMappedPointer().

cudaError_t cudaD3D9ResourceGetSurfaceDimensions (size_t * pWidth, size_t * pHeight, size_t * pDepth,
IDirect3DResource9 * pResource, unsigned int face, unsigned int level)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pWidth, *pHeight, and *pDepth the dimensions of the subresource of the mapped Direct3D
resource pResource which corresponds to face and level.
Since anti-aliased surfaces may have multiple samples per pixel, it is possible that the dimensions of a
resource will be an integer factor larger than the dimensions reported by the Direct3D runtime.
The parameters pWidth, pHeight, and pDepth are optional. For 2D surfaces, the value returned in *pDepth
will be 0.
If pResource is not of type IDirect3DBaseTexture9 or IDirect3DSurface9 or if pResource has not been
registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned.
For usage requirements of face and level parameters, see cudaD3D9ResourceGetMappedPointer.
Parameters:
pWidth - Returned width of surface
pHeight - Returned height of surface
pDepth - Returned depth of surface
pResource - Registered resource to access
face - Face of resource to access
level - Level of resource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle,
Note:
Note that this function may also return error codes from previous, asynchronous launches.
See also:
cudaGraphicsSubResourceGetMappedArray
cudaError_t cudaD3D9ResourceSetMapFlags (IDirect3DResource9 * pResource, unsigned int flags)
Deprecated
This function is deprecated as of CUDA 3.0.
Set flags for mapping the Direct3D resource pResource.
Changes to flags will take effect the next time pResource is mapped. The flags argument may be any of the
following:
• cudaD3D9MapFlagsNone: Specifies no hints about how this resource will be used. It is therefore assumed
that this resource will be read from and written to by CUDA kernels. This is the default value.
• cudaD3D9MapFlagsReadOnly: Specifies that CUDA kernels which access this resource will not write to this
resource.
• cudaD3D9MapFlagsWriteDiscard: Specifies that CUDA kernels which access this resource will not read from
this resource and will write over the entire contents of the resource, so none of the data previously
stored in the resource will be preserved.
If pResource has not been registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned.
If pResource is presently mapped for access by CUDA, then cudaErrorUnknown is returned.
Parameters:
pResource - Registered resource to set flags for
flags - Parameters for resource mapping
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.
