Detailed Description

A set of 3D linestring features, also known as "polylines." Each linestring is basically a simple set of 3D points.

Member Function Documentation

bool vtFeatureSetLineString3D::FindClosest	(	const DPoint2 &	p,
		int &	close_feature,
		DPoint3 &	close_point
	)

For a given 2D point, find the linear feature closest to it (horizontally), and the closest point on that feature. Return true if a feature was found.

void vtFeatureSetLineString3D::Reserve ( int iNum )

virtual

If you know how many entities you will be adding to this FeatureSet, is it more efficient to reserve space for that many.

Implements vtFeatureSet.
