This class represents a Voronoi cell. A Voronoi cell corresponds to a certain site, which is a vertex of the dual Delaunay triangulation.
| bool GEOM_FADE2D::VoroCell2::getAdjacentVCells | ( | std::vector< VoroCell2 * > & | vAdjacentCells | ) | const |
Retrieves the Voronoi cells adjacent to the current cell. The cells are returned in counterclockwise order.
| [out] | vAdjacentCells | a vector to store the adjacent Voronoi cells. |
true if the cell is finite, false otherwise. | double GEOM_FADE2D::VoroCell2::getArea | ( | ) | const |
Retrieves the area of the Voronoi cell. If the cell is finite, the area is computed and returned. If the cell is infinite, -1.0 is returned.
| bool GEOM_FADE2D::VoroCell2::getBoundaryPoints | ( | std::vector< Point2 > & | vPoints, |
| std::vector< Vector2 > * | pvInfiniteDirections = NULL |
||
| ) | const |
This method retrieves the boundary points of the current Voronoi cell as Point2 objects. The points are returned in counterclockwise order.
| [out] | vPoints | contains the boundary points in counterclockwise order. |
| [out] | pvInfiniteDirections | an optional vector to store the directions of the infinite Voronoi edges. If the cell is finite, this parameter is ignored. Default value: NULL |
true if the cell is finite, false otherwise.| double GEOM_FADE2D::VoroCell2::getCentroid | ( | Point2 & | centroid | ) | const |
Retrieves the centroid of the Voronoi cell and its area. If the cell is finite, the area is computed and returned. If the cell is infinite, -1.0 is returned for the area.
| [out] | centroid | the centroid of the Voronoi cell. |
| int GEOM_FADE2D::VoroCell2::getCustomCellIndex | ( | ) | const |
Retrieves the custom cell index that was set previously. Returns -1 if no custom cell index has been set.
| bool GEOM_FADE2D::VoroCell2::getIncidentTriangles | ( | std::vector< Triangle2 * > & | vIncTriangles | ) | const |
Retrieves the Delaunay triangles that are incident to the site of the Voronoi cell. These triangles are returned in counterclockwise order.
| [out] | vIncTriangles | a vector to store the Delaunay triangles incident to the site of the cell. |
true if the cell is finite, false otherwise. | bool GEOM_FADE2D::VoroCell2::getNeighborSites | ( | std::vector< Point2 * > & | vSites | ) | const |
Retrieves the sites of the Voronoi cells adjacent to the current cell in counterclockwise order.
| [out] | vSites | a vector to store the sites of the neighbor cells. |
true if the cell is finite, false otherwise. | Point2* GEOM_FADE2D::VoroCell2::getSite | ( | ) | const |
Retrieves the site associated with the current Voronoi cell. The site is also a vertex of the dual Delaunay triangulation.
Point2. | bool GEOM_FADE2D::VoroCell2::getVoronoiVertices | ( | std::vector< VoroVertex2 * > & | vVoroVertices | ) | const |
Get Voronoi vertices
Used to retrieve the Voronoi vertices of the cell.
| [out] | vVoroVertices | contains VoroVertex2 objects of the current cell in counterclockwise order. |
true if the cell is finite, false otherwise.| bool GEOM_FADE2D::VoroCell2::isFinite | ( | ) | const |
Checks if the current Voronoi cell is finite.
true if the cell is finite, false otherwise. | void GEOM_FADE2D::VoroCell2::setCustomCellIndex | ( | int | customCellIndex_ | ) |
Use this method to associate Voronoi cells with your own data structures or to assign labels for visualization.
| customCellIndex_ | an arbitrary integer that will be assigned to the Voronoi cell. |
