Constructor & Destructor Documentation

MeshNodesOnPoint()

MeshGeoToolsLib::MeshNodesOnPoint::MeshNodesOnPoint	(	MeshLib::Mesh const &	mesh,
		GeoLib::Grid< MeshLib::Node > const &	mesh_grid,
		GeoLib::Point const &	pnt,
		double	epsilon_radius,
		SearchAllNodes	search_all_nodes )

Constructor of object, that search mesh nodes at a GeoLib::Point point within a given search radius.

Parameters

mesh	Mesh object whose nodes are searched
mesh_grid	Grid object constructed with mesh nodes
pnt	a point
epsilon_radius	Search radius
search_all_nodes	whether this searches all nodes or only base nodes
