Detailed Description

This class represents a Voronoi cell. A Voronoi cell corresponds to a certain site which is also a vertex of the dual Delaunay triangulation.

Member Function Documentation

getAdjacentVCells()

bool GEOM_FADE2D::VoroCell2::getAdjacentVCells

(

std::vector< VoroCell2 * > &

vAdjacentCells

)

const

Get adjacent Voronoi cells

Parameters

vAdjacentCells

is used to return the neighbor cells in counterclockwise order.

Returns

whether the cell is finite.

getArea()

double GEOM_FADE2D::VoroCell2::getArea

(

)

const

Get the area

Returns

the area of the cell if it is finite or -1.0 for an infinite cell.

getBoundaryPoints()

bool GEOM_FADE2D::VoroCell2::getBoundaryPoints	(	std::vector< Point2 > &	vPoints,
		std::vector< Vector2 > *	pvInfiniteDirections = NULL
	)		const

Get boundary points

Use this method to retrieve the Voronoi vertices of the present cell as Point2.

Parameters

[out]	vPoints	contains the boundary points in counterclockwise order.
[out]	pvInfiniteDirections	can optionally be used to retrieve the directions of the infinite Voronoi edges: When a pointer to a vector is provided for pvInfiniteDirections and the cell is finite, then the first stored Vector2 describes the direction of the infinite edge at vPoints[0] and the second one the direction of the infinite edge at vPoints.back().

Returns

whether the cell is finite

getCentroid()

double GEOM_FADE2D::VoroCell2::getCentroid

(

Point2 &

centroid

)

const

Get the centroid and area

Parameters

centroid

Returns

the area of the cell if it is finite OR -1.0 for an infinite cell.

getCustomCellIndex()

int GEOM_FADE2D::VoroCell2::getCustomCellIndex

(

)

const

Get custom cell-index

Returns

the custom cell index that has been set before or -1 when no custom cell index has been set.

getIncidentTriangles()

bool GEOM_FADE2D::VoroCell2::getIncidentTriangles

(

std::vector< Triangle2 * > &

vIncTriangles

const

Get incident triangles

The site of the present Voronoi cell is also a vertex of the dual Delaunay triangulation.

Parameters

vVoroVertices

)

const

Get Voronoi vertices

Used to retrieve the Voronoi vertices of the cell.

Parameters

[out]

vVoroVertices

contains VoroVertex2 objects in counterclockwise order.

Returns

whether the cell is finite

isFinite()

bool GEOM_FADE2D::VoroCell2::isFinite

(

)

const

Returns

whether the cell is finite

setCustomCellIndex()

void GEOM_FADE2D::VoroCell2::setCustomCellIndex

(

int

customCellIndex_

)

Set custom cell-index

Use this method to associate Voronoi cells with your own data structures or to assign labels for a visualization.

Parameters

customCellIndex_

is an arbitrary integer
