Constructor & Destructor Documentation

VAPoR::WaveletBlock3D::WaveletBlock3D	(	unsigned int	bs,
		unsigned int	n,
		unsigned int	ntilde,
		unsigned int	nthreads
	)

Constructor for the WaveletBlock3D class.

Parameters

[in]	bs	Dimension of a block along X, Y, and Z coordinates axis
[in]	Number	of wavelet filter coefficients. Valid values are from 1 to Lifting1D::MAX_FILTER_COEFF
[in]	ntilde	Number of wavelet lifting coefficients. Valid values are from 1 to Lifting1D::MAX_FILTER_COEFF
[in]	nthreads	Number of execution threads that may be used by the class for parallel execution.

Note: The success or failure of this constructor can be checked with the GetErrCode() method.

Member Function Documentation

void VAPoR::WaveletBlock3D::ForwardTransform	(	const float *	src_super_blk[8],
		float *	dst_super_blk[8]
	)

Perform a forward wavelet transform on a super block

Performs a forward, 3D wavelet transform on each of eight neighboring blocks contained in a super block, src_super_blk. The resulting Lambda and Gamma coefficients are stored in a destination super block, dst_super_blk. The distribution of coefficients stored in the space pointed to by dst_super_blk is as follows: block 0 contains the L (Lambda) subband, block 1 contains the Hz (Gamma) subband, blocks 2 & 3 contain the Hy subband, blocks 4 - 7 contain the Hx subband.

Parameters

[in]	src_super_blk	An array of pointers to blocks.
[out]	dst_super_blk	An array of pointers to blocks.

Note: The resulting transformed coefficients are stored as tranposed arrays. The blocks may be re-ordered to conventional, X, Y, Z order with the Transpose() method.

void VAPoR::WaveletBlock3D::inverse_transform_thread ( )

void VAPoR::WaveletBlock3D::InverseTransform	(	const float *	src_super_blk[8],
		float *	dst_super_blk[8]
	)

Perform an inverse wavelet transform on a super block

Performs a inverse, 3D wavelet transform on each of eight neighboring blocks contained in a super block, src_super_blk. The resulting coefficients are stored in a destination super block, dst_super_blk.

Parameters

[in]	src_super_blk	An array of pointers to blocks
[out]	dst_super_blk	An array of pointers to blocks.

See also: ForwardTransform()

void VAPoR::WaveletBlock3D::TransposeBlks ( float * super_blk[8] )

Transpose a super block created by ForwardTransform() to X, Y, Z order.

The gamma coefficient blocks returned by ForwardTransform() are tranposed. This method can be used to perform an in-place tranpose restoring gamma blocks to their natural, X, Y, Z order.

Parameters

[in,out] src_super_blk An array of pointers to blocks
