Detailed Description

parametric tensor product B-spline surface.

NAME: ParametricTPSurface - parametric tensor product B-spline surface

DESCRIPTION:

A class for representation of the parametric tensor product surface. It is built on the basis of class TPSurface

Constructor & Destructor Documentation

ParametricTPSurface::ParametricTPSurface ( ) [inline]
 

No special initialization is needed.

ParametricTPSurface::~ParametricTPSurface ( ) [inline]
 

Member Function Documentation

Ptv(NUMT) ParametricTPSurface::derivative ( int order1,
int order2,
real t1,
real t2 )
 

returns also a "Ptv(NUMT)" as result which contains the corresponding derivatives to the two parameters.

void ParametricTPSurface::getCoef ( MatSimple(NUMT) & xc,
MatSimple(NUMT) & yc,
MatSimple(NUMT) & zc )
 

gets the coefficients.

void ParametricTPSurface::interpolation ( const MatSimple(NUMT) & xm,
const MatSimple(NUMT) & ym,
const MatSimple(NUMT) & zm,
int k1 = 4,
int k2 = 4,
const char * method1 = "Uniform",
const char * method2 = "Uniform",
bool repeat = false )
 

carries out interpolation according to input data. This is the only interpolation function in the class. The orders for the two spline spaces can be specified as input. The function operates in two modes:

(i) If both of the Spline spaces are already built up and the input data are suitable, an interpolation is taken out using the original spline spaces.

(ii) Otherwise, new spline spaces will be created and used in the inpolation process.

void ParametricTPSurface::makeTable ( int num1,
int num2,
MatSimple(NUMT) & xtable,
MatSimple(NUMT) & ytable,
MatSimple(NUMT) & ztable )
 

fills three "MatSimple(NUMT)" objects with x,y and z values.

bool ParametricTPSurface::ok ( ) const
 

checks whether the surface is ready for usage.

Ptv(NUMT) ParametricTPSurface::operator() ( real t1,
real t2 )
 

bool ParametricTPSurface::redim ( const SplineSpace & space1_,
const SplineSpace & space2_ ) [inline]
 

attaches new spline spaces.

void ParametricTPSurface::scan ( Is is )
 

reads interpolating data directly from an ASCII file and carries out cubic interpolation.

void ParametricTPSurface::setCoef ( const MatSimple(NUMT) & xc,
const MatSimple(NUMT) & yc,
const MatSimple(NUMT) & zc )
 

assigns the three coefficient matrices.
