Constructor Detail

PgTetraVertexStar

public PgTetraVertexStar()

Constructor.

Method Detail

init

public void init()

Initialization.

getTetIndex

public PiVector getTetIndex()

Get list of adjacent tetrahedra.

getVertexLocInd

public PiVector getVertexLocInd()

Get list of local indices of central vertex in adjacent tetrahedra.

getNeighbourVertexStarInd

public PiVector[] getNeighbourVertexStarInd()

Get neighbour information in the vertexStar. Neighbour information is given like in PgTetraSet by neighbour tetrahedron indices, stored to the opposite vertices, but with indices refering to the position in the vertex star's m_tetIndex array

isClosed

public boolean isClosed()

Get closed information - vertex star is not closed if the center vertex is at the boundary.

getSize

public int getSize()

Get number of tetrahedra in vertex star.

makeVertexStar

public void makeVertexStar(PgTetraSet tetraSet,
                           int vertexInd,
                           int tetInd)

Compute the vertex star for a given vertex index.

Parameters:

tetraSet - The tetraSet carrying the connectivity information.

vertexInd - Index of the center vertex for the Vertex Star.

tetInd - Index of an adjacent tetrahedron, may (but should not) be -1.
