[vtkusers] How to create vtkPolyDataObject from coordinates

[arwtyxouymz]

Hi,

I have two problems.

Firstly,
I have a set of coordinates, and I want to convert the set to vtkPolyData.

Secondly,
after the converting, I want to calculate the normals at each points in
vtkPolyData.

I think my second problem can be solved by using vtkPolyDataNormals, but my
set of coordinates is very complex, so I'm worry about the normals are
calculated correctly.

I attach the example of my set.

I want to convert the red part to vtkPolyData, and I have the coordinates of
red part.

How should i do?

please help me!
