Detailed Description

Class to handle Radial Basis Function with a large set of 3D points as nodes.

The class specializes RBFKernel and employs a 3D point cloud as set of RBF nodes.

Examples

RBF() [1/2]

bitpit::RBF::RBF

(

RBFBasisFunction

bfunc = RBFBasisFunction::WENDLANDC2

)

Default constructor. RBFBasisFunction::WENDLANDC2 is default. RBFMode is INTERP, by default. Use setMode for changing it.

Default constructor. Requires optionally statements of type of RBFBasisFunction which must be used. RBFMode is INTERP, by default. Use setMode for changing it.

Member Function Documentation

addNode() [1/2]

int bitpit::RBF::addNode

(

const std::array< double, 3 > &

node

)

Adds a RBF node and sets it to active. Does not manage duplicated nodes. Supported in both modes.

Parameters

[in]

node

coordinates of node to be added

Returns

id of node within class

Examples

RBF_example_00001.cpp.

Definition at line 1271 of file rbf.cpp.

addNode() [2/2]

std::vector< int > bitpit::RBF::addNode

(

const std::vector< std::array< double, 3 > > &

node

)

Adds a list of RBF nodes and sets them to active. Does not manage duplicated nodes. Supported in both modes.

Parameters

[in]

node

coordinates of nodes to be added

Returns

id of node within class

Definition at line 1286 of file rbf.cpp.

getTotalNodesCount()

int bitpit::RBF::getTotalNodesCount

(

)

Gets the total number of nodes, active or not. Supported in both modes.

Returns

number of available RBF nodes

Definition at line 1260 of file rbf.cpp.

removeAllNodes()

void bitpit::RBF::removeAllNodes

(

)

Remove all nodes in RBF nodal list. Supported in both modes.

Definition at line 1347 of file rbf.cpp.

removeNode() [1/2]

bool bitpit::RBF::removeNode

(

int

id

)

Remove pre-existent node. RBF Node list is resized and renumbered after extraction. Supported in both modes.

Parameters

[in]

id

id of node

Returns

boolean, true if successfully extracted, false otherwise

Definition at line 1311 of file rbf.cpp.

removeNode() [2/2]

bool bitpit::RBF::removeNode

(

std::vector< int > &

list

)

Remove pre-existent set of nodes. RBF nodal list is resized and renumbered after extraction. Supported in both modes.

Parameters

[in]

list

id list of candidates to extraction

Returns

boolean, true if all nodes are successfully extracted, false if any of them or none are extracted

Definition at line 1329 of file rbf.cpp.

swap()

void bitpit::RBF::swap ( RBF & other )

protectednoexcept

Swap method. Exchange contents of each class member with those corresponding in the argument object.

Parameters

[in]

other

object to be swapped

Definition at line 1249 of file rbf.cpp.
