Detailed Description

Information on volume node data.

This class represents all information needed for trilinear interpolation and partial derivative computation. It holds a grid location and the node data on the corners of the grid cube containing that location.

byte cmtk::ProbeInfo::GetNumberOfValuesAbove

(

const Types::DataItem

threshold )

const [inline]

Return number of values above (or equal to) threshold.

Definition at line 116 of file cmtkProbeInfo.h.

byte cmtk::ProbeInfo::GetNumberOfValuesBelow

(

const Types::DataItem

threshold )

const [inline]

Return number of values below threshold.

Definition at line 127 of file cmtkProbeInfo.h.

Vector3D& cmtk::ProbeInfo::GetPartialDerivatives

(

Vector3D &

d )

const [inline]

Return partial derivatives of node data w.r.t.

grid dimensions. The data on the cube faces is used for a finite-difference approximation of the first-order derivatives w.r.t. the grid dimensions x, y, and z.

Parameters:

d	The object of type Vector3D in which the result is to be stored.

Returns:

A reference to the destination parameter.

Types::Coordinate cmtk::ProbeInfo::Offsets[6]

Relative location of the probed coordinate.

Represented are the relative distances of the probed coordinate from the surrounding cube's faces. Values range from 0 to 1. The order of the coefficients is dX0, dY0, dZ0, dX1, dY1, dZ1. Lower x-coordinates for example are weighted with dX0, others respectively.

Types::DataItem cmtk::ProbeInfo::Values[8]

Node data on cube corners around given location.

The order of the data elements is as follows: (x0,y0,z0), (x1,y0,z0), (x0,y1,z0), (x1,y1,z0), (x0,y0,z1), (x1,y0,z1), (x0,y1,z1), (x1,y1,z1).
