Rx::LFR::Net::ICudaDataImages::~ICudaDataImages ( )

inline

Destructor.

Member Function Documentation

virtual void Rx::LFR::Net::ICudaDataImages::Download ( EImage  eImgID, Rx::Net::Image^  xImg  )

inlinevirtual

Downloads the image with the given image ID.

Parameters

eImgID	The image ID.
xImg	[in,out] If non-null, the image.

virtual void Rx::LFR::Net::ICudaDataImages::Free ( EImage  eImgID )

inlinevirtual

Frees memory used by image defined by eImgID. This invalidates the image.

Parameters

eImgID

The image ID.

virtual void Rx::LFR::Net::ICudaDataImages::FreeAll ( )

inlinevirtual

Frees the memory used by all images. This invalidates all images.

virtual size_t Rx::LFR::Net::ICudaDataImages::GetDevicePointerPitch ( EImage  eImgID )

inlinevirtual

Gets device pointer pitch, which is the width in bytes of the allocation. Given a row and column of an array element of type T, the address is computed as:

T* pElement = (T*)((char*)BaseAddress + Row * pitch) + Column;

Parameters

eImgID

The image ID.

Returns

The device pointer pitch.

// Host code:
// Assuming the image in this example is of type luminance, float (TPixel_L_f).
char* pcBaseAdress = (char*) GetImageDevicePointer(EImage::DepthRay);
size_t nPitch = GetDevicePointerPitch(EImage::DepthRay);

// CUDA code:
// Get the pointer of the pixel on the CUDA device, at row 10 and column 42.
Rx::TPixel_L_f* tPixel = (((Rx::TPixel_L_f*) (pcBaseAdress + 10 * nPitch)) + 42);

virtual System::IntPtr Rx::LFR::Net::ICudaDataImages::GetImageDevicePointer ( EImage  eImgID )

inlinevirtual

Gets the CUDA device pointer to the data of the image defined by the given ID.

The pointer maps to the memory on a CUDA device and cannot be used on the host.

Parameters

eImgID

The image ID.

Returns

The image device pointer.

virtual Rx::Net::ImageFormat ^ Rx::LFR::Net::ICudaDataImages::GetImageFormat ( EImage  eImgID )

inlinevirtual

Gets the image format of the image defined by the given ID.

Parameters

eImgID

The image ID.

Returns

The image format.

virtual bool Rx::LFR::Net::ICudaDataImages::IsValid ( EImage  eImgID )

inlinevirtual

Query if the image with the given image ID is valid.

Parameters

eImgID

The image ID.

Returns

True if valid, false if not.

virtual void Rx::LFR::Net::ICudaDataImages::Upload ( EImage  eImgID, Rx::Net::Image^  xImg  )

inlinevirtual

Uploads the image with the given image ID.

Parameters

eImgID	The image ID.
xImg	[in,out] If non-null, the image.
