[vtkusers] Question ? [Reading data from txt file]

[agatte]

Hi ;)

I have very simple question a propos de reading txt file
I have a data in txt file :
<nb points>
<nb triangles>
<point 0 X> <point 0 Y> <point 0 Z>
<point 1 X> <point 1 Y> <point 1 Z>
...
<point N X> <point N Y> <point N Z>
<triangle 0 A> <triangle 0 B> <triangle 0 C>
<triangle 1 A> <triangle 1 B> <triangle 1 C>
...
This is example :

2778
5552
3.060173	 -23.518985	 34.600001
2.738770	 -23.433715	 34.675001
2.868080	 -23.186338	 34.385715

4.470410	 -23.289412	 34.350001
4.601595	 -23.551782	 34.600..
....

2659	 2777	 2778
2658	 2777	 2659

What I could read it in VTK ?

I have already tried with  example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/InfoVis/ReadDelimitedFile

But I couldn't read well data value of points/triangle. 
I received : output :
x: 1.#QNANy: 0z: 0 n: 0 0 0
x: 1.#QNANy: 0z: 0 n: 0 0 0
x: 1.#QNANy: 0z: 0 n: 0 0 0
x: 1.#QNANy: 0z: 0 n: 0 0 0
x: 1.#QNANy: 0z: 0 n: 0 0 0

x: 1.#QNANy: 0z: 0 n: 0 0 0
x: 1.#QNANy: 0z: 0 n: 0 0 0...



I would appreciate for any help or advice.
