Detailed Description

Base class that does the majority of the work finding bendpoints. Adaptions to different data-types are done in subclasses.

Constructor & Destructor Documentation

BendPointFinderBase::BendPointFinderBase ( int  sz, float  eps  )

protected

Member Function Documentation

const TypeSet<int>& BendPointFinderBase::bendPoints ( ) const

inline

bool BendPointFinderBase::doFinish ( bool  success )

protectedvirtual

Called after all doWork have finished.

Parameters

success

indicates whether all doWork returned true.

Reimplemented from ParallelTask.

bool BendPointFinderBase::doPrepare ( int  nrthreads )

protectedvirtual

Called once, before any doWork is called.

Reimplemented from ParallelTask.

bool BendPointFinderBase::doWork ( od_int64  , od_int64  , int    )

protected

void BendPointFinderBase::findInSegment ( int  , int    )

private

virtual float BendPointFinderBase::getMaxSqDistToLine ( int &  idx, int  start, int  stop  ) const

protectedpure virtual

Give the index of the point that is furthest from the line from start to stop.

Returns

the squre of the largest distance

Implemented in BendPointFinder3D, and BendPointFinder2DBase.
