const [virtual]

Returns the squared distance to this.

if this has more than two vertices (ie. more than one line segment), acts on the closest line segment.

virtual bool DtVertexList::getClosestVertex	(	const DtVector &	point,
		DtVector &	vertex
	)		const [virtual]

Sets vertex to be the vertex closest to point in this object geometry.

Referenced by DtLocalVectorIterator::setToClosest(), and DtRwVectorIterator::setToClosest().

virtual DtListItem* DtVertexList::getClosestVertex

(

const DtVector &

point

)

const [virtual]

Returns a pointer to the item in this list which is closestto point.

virtual bool DtVertexList::getClosestLine	(	const DtVector &	point,
		DtVector &	linePt1,
