[vtkusers] Converting Points to Vertices

Hi Erik,
I'm assuming that your points are stored in a vtkPoints data structure.
You will need to create a vtkPolyData and set points to the vtkPoints
You will need to create a vtkCellArray and add the points then use

Here is an example (in C++):

vtkPolyData *PointsPoly=vtkPolyData::New();
vtkPoints *Points=vtkPoints::New();
vtkCellArray *Verts=vtkCellArray::New();

// Fill your points in 'Points'

int NumberOfVerts= // Fill hte number of points in here;

for(int i=0;i<NumberOfVerts;i++)
	int Id=i;


Good luck
