[vtkusers] Point selection

[Carlos Martinez Burgos]

Hi all.

I have a PolyData with many vertexes forming a point cloud. I render it
successfully. I use a PointPicker to select points from the cloud. I get
the cell id and I know what point I have selected.

I want to change the color of that point, without change the others. Can I
change the properties of each point of the polydata independently? Should
I use a new polydata with one vertex in the same position and set its
properties?

How can I do it?

Thanks.
