Member Function Documentation

void VtkWriter::set_transform_position

(

bool

transform_position

)

[inline]

Sets the variable that toggles the transform from ijk to RAS before writing the fiber to VTK.

void VtkWriter::State2Tensor	(	State &	state,
		mat_t &	D,
		int	tensorNumber
	)			[protected]

Reconstructs the tensor from the state for each case.

Parameters:

[out]

D

The calculated diffusion tensor

Todo:

I think there is something wrong with choosing a orthonormal basis for the tensor

bool VtkWriter::Write	(	const std::string &	file_name,
		const std::string &	tractsWithSecondTensor,
		const std::vector< Fiber > &	fibers,
		bool	write_state,
		bool	store_glyphs
	)

Writes the fibers to the VTK file and attaches the selected values to the fiber.

Parameters:

[in]	file_name	The path of the output fiber file (*.vtk)
[in]	tractsWithSecondTensor	File path for the fibers generated with the second tensor This one is optional.
[in]	store_glyphs	Write glyphs (i.e. main tensor directions) to a file named glyphs_{tracts}.

void VtkWriter::writeFibersAndTensors	(	std::ofstream &	output,
		const std::vector< Fiber > &	fibers,
		const int	tensorNumber
	)			[protected]

Writes the fibers and all values attached to them to a VTK file

bool VtkWriter::WriteGlyphs	(	const std::string &	file_name,
		const std::vector< Fiber > &	fibers
	)

Write the glyphs (i.e. main tensor directions) to a file named glyphs_{tracts}.

void VtkWriter::WritePoint	(	const vec_t &	point,
		std::ofstream &	output,
		int &	counter
	)			[protected]

Writes a point to the output stream, and performs the ijk-RAS transform if set to do so. Also this function makes sure that the output VTK file is well formatted.
