ComputeTrianglesConnectivity() [1/3]

std::vector< std::size_t > Kratos::DelaunatorUtilities::ComputeTrianglesConnectivity

(

const std::vector< double > &

rCoordinates

)

This method returns the triangles connectivity from a list of coordinates (using triangle library)

Parameters

rCoordinates

The list of coordinates, first X, then Y, for each point of the point cloud

Returns

The connectivity vector

ComputeTrianglesConnectivity() [2/3]

std::pair< std::vector< std::size_t >, std::vector< double > > Kratos::DelaunatorUtilities::ComputeTrianglesConnectivity	(	const std::vector< double > &	rCoordinates,
		const std::vector< std::array< double, 2 >> &	rSegments,
		const double	AreaConstraint = 0
	)

This methods does a Constrained Delaunay Triangularization from a list of coordinates and segments (using triangle library)

Parameters

rCoordinates	The list of coordinates, first X, then Y, for each point of the point cloud
rSegments	The list of segments, each segment is determined in one std::array with from its i and j nodal ids
AreaConstraint	If provided, imposes that value as a constraint on the maximum area

Returns

A pair containing in first position a list with the triangles connectivities and in second position a list with the x and y nodal coordinates
