NAME
vtkEdgePoints - generate points on isosurface
SYNOPSIS
#include "/opt/vtk-c++/graphics/vtkEdgePoints.h"
class VTK_EXPORT vtkEdgePoints : public vtkDataSetToPolyDataFilter
vtkEdgePoints();
static vtkEdgePoints *New() {return new vtkEdgePoints;};
const char *GetClassName() {return "vtkEdgePoints";};
void PrintSelf(ostream& os, vtkIndent indent);
void SetValue(float);
float GetValue();
DESCRIPTION
vtkEdgePoints is a filter that takes as input any dataset and generates for output a set of points that lie on an isosurface. The points are created by interpolation along cells
edges whose end-points are below and above the contour value.
CAVEATS
vtkEdgePoints can be considered a "poor man's" dividing cubes algorithm (see vtkDividingCubes). Points are generated only on the edges of cells, not in the interior, and at lower density than dividing cubes. However, it is more general than dividing cubes since it treats any type of dataset.
SUMMARY
void SetValue(float)
Set/get the contour value.
vtkEdgePoints()
Construct object with contour value of 0.0.
