Syntax

public static class TextureObjects

Methods

cuTexObjectCreate(ref CUtexObject, ref CudaResourceDesc, ref CudaTextureDescriptor, ref CudaResourceViewDesc)

Creates a texture object and returns it in pTexObject. pResDesc describes the data to texture from. pTexDesc describes how the data should be sampled. pResViewDesc is an optional argument that specifies an alternate format for the data described by pResDesc, and also describes the subresource region to restrict access to when texturing. pResViewDesc can only be specified if the type of resource is a CUDA array or a CUDA mipmapped array.

Declaration

public static CUResult cuTexObjectCreate(ref CUtexObject pTexObject, ref CudaResourceDesc pResDesc, ref CudaTextureDescriptor pTexDesc, ref CudaResourceViewDesc pResViewDesc)

Parameters

Type	Name	Description
CUtexObject	pTexObject	Texture object to create
CudaResourceDesc	pResDesc	Resource descriptor
CudaTextureDescriptor	pTexDesc	Texture descriptor
CudaResourceViewDesc	pResViewDesc	Resource view descriptor

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuTexObjectCreate(ref CUtexObject, ref CudaResourceDesc, ref CudaTextureDescriptor, IntPtr)

Creates a texture object and returns it in pTexObject. pResDesc describes the data to texture from. pTexDesc describes how the data should be sampled. pResViewDesc is an optional argument that specifies an alternate format for the data described by pResDesc, and also describes the subresource region to restrict access to when texturing. pResViewDesc can only be specified if the type of resource is a CUDA array or a CUDA mipmapped array.

Declaration

public static CUResult cuTexObjectCreate(ref CUtexObject pTexObject, ref CudaResourceDesc pResDesc, ref CudaTextureDescriptor pTexDesc, IntPtr pResViewDesc)

Parameters

Type	Name	Description
CUtexObject	pTexObject	Texture object to create
CudaResourceDesc	pResDesc	Resource descriptor
CudaTextureDescriptor	pTexDesc	Texture descriptor
System.IntPtr	pResViewDesc	Resource view descriptor (Null-Pointer)

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuTexObjectDestroy(CUtexObject)

Destroys the texture object specified by texObject.

Declaration

public static CUResult cuTexObjectDestroy(CUtexObject texObject)

Parameters

Type	Name	Description
CUtexObject	texObject	Texture object to destroy

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuTexObjectGetResourceDesc(ref CudaResourceDesc, CUtexObject)

Returns the resource descriptor for the texture object specified by texObject.

Declaration

public static CUResult cuTexObjectGetResourceDesc(ref CudaResourceDesc pResDesc, CUtexObject texObject)

Parameters

Type	Name	Description
CudaResourceDesc	pResDesc	Resource descriptor
CUtexObject	texObject	Texture object

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuTexObjectGetResourceViewDesc(ref CudaResourceViewDesc, CUtexObject)

Returns the resource view descriptor for the texture object specified by texObject. If no resource view was set for texObject, the ::CUDA_ERROR_INVALID_VALUE is returned.

Declaration

Parameters

Type	Name	Description
CudaResourceViewDesc	pResViewDesc	Resource view descriptor
CUtexObject	texObject	Texture object

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuTexObjectGetTextureDesc(ref CudaTextureDescriptor, CUtexObject)

Returns the texture descriptor for the texture object specified by texObject.

Declaration

public static CUResult cuTexObjectGetTextureDesc(ref CudaTextureDescriptor pTexDesc, CUtexObject texObject)

Parameters

Type	Name	Description
CudaTextureDescriptor	pTexDesc	Texture descriptor
CUtexObject	texObject	Texture object

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.
