Detailed Description

TriLinearInterpolator performs a linear interpolation in x then y then z

Performs a linear interpolation in x then y then z returning a 1D value.

Definition at line 38 of file TriLinearInterpolator.h.

Constructor & Destructor Documentation

interpolation::TriLinearInterpolator::TriLinearInterpolator ( ThreeDGrid *  grid, double ***  F  )

inline

Constructor for grids with constant spacing

Parameters

grid	3d mesh on which data is stored - adds a reference to *this into the mesh smart pointer thing.
F	function data with points on each element of the grid. Indexing goes like [index_x][index_y][index_z]. Interpolator3dGridTo1d now owns this memory All the data handling is done at Interpolator3dGridTo1d

Definition at line 83 of file TriLinearInterpolator.h.

void interpolation::TriLinearInterpolator::function ( const double  Point[3], double  Value[1]  ) const

virtual

Get the interpolated value of the function at some point

First does bound checking, then makes linear interpolations using the standard 1d interpolation formula
\(y(x) \approx \frac{\Delta y}{\Delta x} dx + y_0\)
\(y(x) \approx \frac{y_1(x_1)-y_0(x_0)}{dx}(x-x_0) + y_0\)
Interpolate along 4 x grid lines to make a 2D problem, then interpolate along 2 y grid lines to make a 1D problem, then finally interpolate in z to get the value.

Implements interpolation::Interpolator3dGridTo1d.
