Detailed Description

A one-dimensional bicubic-interpolated look-up table.

The curve input is a discrete set of (x, y) pairs sampled from a continuous curve y = F(x). A smooth curve is formed from these points using bicubic interpolation, and then resampled at a specified number of evenly spaced values of x. The resampled values can then be used as a fast lookup table (with linear interpolation) to find y(x).

Constructor & Destructor Documentation

Curve::Curve ( )

Default constructor.

Copy constructor.

Curve::~Curve ( ) [virtual]

Destructor.

Member Function Documentation

vector_t InterpolatedData< float >::_compute_second_derivatives ( const vector_t & breaks,

const vector_t & data

) [protected, inherited]

void Curve::_compute_second_derivatives ( ) [protected, virtual]

Compute the second derivative for bicubic interpolation.

Implements InterpolatedData< float >.

std::string Curve::asString ( ) [virtual]

String representation.

Implements BaseType.

void BaseType::convertXML ( ) [virtual, inherited]

Convert XML data to internal format prior to serialization.
This method is currently only called by the XML parser for Object classes. If another BaseType class requires this method, a call must be added to the appropriate XML handler in the parser.

void Curve::dumpCurve ( FILE * f ) const

Dump the y(x) lookup table to an output file.

int InterpolatedData< float >::find ( vector_t b,

value_t v

) const [inherited]

Curve::vector_t Curve::getBreaks ( )

Get a list of the x values of the source data set.

virtual value_t InterpolatedData< float >::getPrecise ( value_t ,

value_t

) const [virtual, inherited]

Curve::value_t Curve::getPrecise ( value_t x ) const

Get the "precise" value y(x) from bicubic interpolation.

virtual value_t InterpolatedData< float >::getValue ( value_t ,

value_t

) const [virtual, inherited]

Curve::value_t Curve::getValue ( value_t x ) const

Get the "quick and dirty" value of y(x) from linear interpolation of the resampled lookup table.

void Curve::interpolate ( value_t spacing )

Interpolate the source data set and resample at at equaly spaced values of x to form the lookup table.

Parameters:

spacing the spacing between resampled values of X

const Curve & Curve::operator= ( const Curve & )

Assignment operator.

void BaseType::parseXML ( const char * cdata ) [virtual, inherited]

Parse cdata from within the XML tags for this object.

Reimplemented in SimDate, EnumLink, GeoPos, LLA, UTM, Matrix3, Quat, Real, and Vector3.

void Curve::serialize ( Archive & ) [virtual]

Serialize to or from a data archive.

Reimplemented from InterpolatedData< float >.

void Curve::setBreaks ( const vector_t & breaks )

Set the x values of the source data set.

void Curve::setData ( const vector_t & data )

Set the y values of the source data set.

std::string Curve::typeString ( ) [virtual]

Type representation.

Implements BaseType.
