Detailed Description

Snaps points at the center of a cell.

vtkCellCentersPointPlacer is a class to snap points on the center of cells. The class has 3 modes. In the ParametricCenter mode, it snaps points to the parametric center of the cell (see vtkCell). In CellPointsMean mode, points are snapped to the mean of the points in the cell. In 'None' mode, no snapping is performed. The computed world position is the picked position within the cell.

Usage:
The actors that render data and wish to be considered for placement by this placer are added to the list as
placer->AddProp( actor );

double  worldOrient[9] 
)
overridevirtual

Given a renderer and a display position in pixel coordinates, compute the world position and orientation where this point will be placed.

This method is typically used by the representation to place the point initially. For the Terrain point placer this computes world points that lie at the specified height above the terrain.

Reimplemented from vtkPointPlacer.

◆ ComputeWorldPosition() [2/2]

int vtkCellCentersPointPlacer::ComputeWorldPosition ( vtkRenderer ren,
double  displayPos[2],
double  refWorldPos[3],
double  worldPos[3],
double  worldOrient[9]

Given a renderer, a display position, and a reference world position, compute the new world position and orientation of this point.

This method is typically used by the representation to move the point.

Reimplemented from vtkPointPlacer.

Get the Prop picker.

◆ SetMode()

virtual void vtkCellCentersPointPlacer::SetMode ( int  )
virtual

Modes to change the point placement.

Parametric center picks the parametric center within the cell. CellPointsMean picks the average of all points in the cell. When the mode is None, the input point is passed through unmodified. Default is CellPointsMean.

◆ GetMode()

virtual int vtkCellCentersPointPlacer::GetMode ( )
virtual

Modes to change the point placement.

Parametric center picks the parametric center within the cell. CellPointsMean picks the average of all points in the cell. When the mode is None, the input point is passed through unmodified. Default is CellPointsMean.
