Hi Federico,<br>
<br>
You have to create some vertex cells. So use a polydata or
unstructured grid instead of pointset. Polydata is the easier you'd
make a cell array like this: 1 0 1 1 1 2 ... 1 n where n is the
number of points, and add this with SetVerts method. You won't have
to use the Delaunay filter to see this.<br>

type="cite">Hi. I want to show a colored point cloud (vtkPointSet)
returning from a custom filter. In my custom filter, I prepare the
pointCloud in this way:<br>
<br>
vtkSmartPointer<vtkPointSet> pointCloud =
vtkSmartPointer<vtkPolyData>::New();<br>
pointCloud->SetPoints(points);<br>
pointCloud->GetPointData()->SetScalars(distances);<br>
pointCloud->Update();<br>
<br>
output->DeepCopy(pointCloud);<br>
<br>
points is a vtkPoints and distances is a vtkDoubleArray.<br>
<br>
The problem is that nothing is showing. If instead of using a
vtkPointSet I use a vtkPolyData and filter it with a
vtkDelaunay2D, it shows some points, but other points are left out
(Do you know why is this happening?). If I use a vtkDelaunay3D,
again, I see nothing.<br>
<br>
Do you know why is this happening? What do you recommend to build
point clouds? <br>
<br>
I would really appreciate any suggestion.<br>
<br>
Thanks in advance,<br>
<br>
Federico<br>
