MeshGeoToolsLib::MeshNodesAlongPolyline Class Reference

Detailed Description

This class computes the ids of the mesh nodes along a polyline.

The mesh nodes are sorted as follow: [ ids of sorted nodes according to their distance to the starting point of ply ]

Constructor & Destructor Documentation

MeshNodesAlongPolyline()

MeshGeoToolsLib::MeshNodesAlongPolyline::MeshNodesAlongPolyline	(	MeshLib::Mesh const &	mesh,
		GeoLib::Polyline const &	ply,
		double	epsilon_radius,
		SearchAllNodes	search_all_nodes )

Constructor of object, that search mesh nodes along a GeoLib::Polyline polyline within a given search radius. So the polyline is something like a tube.

Parameters

mesh	Mesh the search will be performed on.
ply	Along the GeoLib::Polyline ply the mesh nodes are searched.
epsilon_radius	Search / tube radius
search_all_nodes	switch between searching all mesh nodes and searching the base nodes.
