Detailed Description

Stores the data of deterministic fiber tractograms.

Derived or optional data as tangents, FA, etc. are not saved in here, and never will be! Just the polylines.

Constructor & Destructor Documentation

◆ WTractData()

WTractData::WTractData	(	std::shared_ptr< std::vector< float > >	pointComponents,
		std::shared_ptr< std::vector< size_t > >	startIndices
	)

Constructs a new WTractData.

Parameters

pointComponents	x, y, and z components of each position of each tract
startIndices	For each tract the index of the first x component in pointComponents.

Member Data Documentation

◆ m_pointComponents

std::shared_ptr< std::vector< float > > WTractData::m_pointComponents

private

Stores the all components of all vertices of all tracts.

First x, y and finally z component are arranged in this manner: $[x_0, y_0, z_0, ..., x_{m_0}, y_{m_0}, z_{m_0}, ... , ..., x_{m_k}, y_{m_k}, z_{m_k}]$ where there are $k$ many tracts where the i'th tract has $m_i$ vertices, but $3m_i$ compontents. In other words: m_points.size() / 3 == number of vertices.

Note: the reason for beeing restricted to float is, that graphic boards and also the tracking algorithms which produce those tracks are just using floats.

Definition at line 63 of file WTractData.h.

◆ m_startIndices

std::shared_ptr< std::vector< size_t > > WTractData::m_startIndices

private

Stores for every tract the index number where it starts in the m_pointComponents array.

This means the index of each tracts first component $x_0$ .

Note: the reason for using size_t instead of unsigned int is that more tracts with more points are in sight.
