allPointsAreRelevant()

bool TriangulatedGridder2D::allPointsAreRelevant ( ) const

overridevirtual

Implements Gridder2D.

clone()

Gridder2D* TriangulatedGridder2D::clone ( ) const

overridevirtual

Implements Gridder2D.

getWeights()

bool TriangulatedGridder2D::getWeights ( const Coord &  , TypeSet< double > &  weights, TypeSet< int > &  relevantpoints  ) const

overridevirtual

Only use this if multiple setValues() are called for the same setPoints() The output weights and pointset must then be provided to the getValue function

Implements Gridder2D.

pointsChangedCB()

bool TriangulatedGridder2D::pointsChangedCB ( CallBacker *  )

overrideprotectedvirtual

Reimplemented from Gridder2D.

setGridArea()

void TriangulatedGridder2D::setGridArea ( const Interval< float > &  , const Interval< float > &    )

overridevirtual

Given that we want to calculate cpt, is data at dpt usable. Tells gridder that you will not call setGridPoint outside these ranges. May speed up calculation.

Reimplemented from Gridder2D.
