Member Function Documentation

◆ coord()

virtual const Coord& BendPointFinder2DBase::coord ( int idx ) const

protectedpure virtual

Implemented in BendPointFinder2DGeom, BendPointFinderTrcKey, and BendPointFinder2D.

◆ getMaxSqDistToLine()

float BendPointFinder2DBase::getMaxSqDistToLine	(	int &	idx,
		int	start,
		int	stop
	)		const

protectedvirtual

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

Returns: the squre of the largest distance

Implements BendPointFinderBase.
