Member Function Documentation

sortByDistance()

virtual void sortByDistance ( const DM::IPoint &  refPt, int  dim, bool  ascending = true  )

pure virtual

sorting points by distance to given reference point

Parameters

[in]	refPt	reference point used for distance computation
[in]	dim	dimension of distance (2 = 2d distance, 3 = 3d distance)
[in]	ascending	sort in ascending or descending order

sortByDistanceAndClip()

virtual void sortByDistanceAndClip ( const DM::IPoint &  refPt, int  dim, double  maxDistance, bool  ascending = true  )

pure virtual

sorting points by distance to given reference point and remove points that exceeds a certain distance

Parameters

[in]	refPt	reference point used for distance computation
[in]	dim	dimension of distance (2 = 2d distance, 3 = 3d distance)
[in]	maxDistance	all points that are further away than the given distance are dropped
[in]	ascending	sort in ascending or descending order
