Detailed Description

interface for analysing distances between polyline objects (see GeometricAlgorithms::analyseDistance)

Member Function Documentation

pure virtual

this function is called if non max. distance threshold is set or the distance is below the given threshold.

Note: if lineIdx1 == lineIdx2 then the closest point is a vertex and not a point on a segment

Parameters

[in]	distance	shortest 3d/2d distance between basePt (=base[idx]) and polyline 'other'
[in]	idx	index of the current vertex (of the base polyline)
[in]	basePt	current vertex (of the base polyline)
[in]	lineIdx1	source point index of closest segment of polyline 'other'
[in]	lineIdx2	target point index of closest segment of polyline 'other'
[in]	minDistPt	point on polyline 'other' with the shortest distance to basePt

virtual void exceeds ( unsigned idx )

pure virtual

this function is called if the distance between the current base vertex and the 'other' polyline exceeds the given distance threshold

Parameters

[in] idx index of the current vertex (of the base polyline)
