[vtkusers] Texture Coordinates

[Camille AFANGNIKE]

Hi Everybody,

I send this message to know how to use vtkTCoords. 

I read email on vtk forum :
..........................................
 Where I had 2D texture coordinates:
>
>vtkTCoords *tcoords = vtkTCoords::New();
>tcoords->SetNumberOfTCoords(N);
>...
>float p[3];
>p[0]=x; p[1]=y;
>tcoords->SetTCoord(i,p);
>...
>
>I replaced with:
>
>vtkFloatArray *tcoords = vtkTCoords::New();
>tcoords->SetNumberOfComponents(2);
>tcoords->SetNumberOfTuples(N);
>...
>float p[2];
>p[0]=x; p[1]=y;
>tcoords->SetTuple(i,p);
>......................................................

In fact my problem is that i can't see the 2D texture i have in my vtk file, after reading it. I don't know how to do with
so i try to recreate a vtkTexture. Do you know how to exploit texture data from a vtk file or could you tell me what to do with vtkTCoords...?
I don't want to reuse the imagedata i used the first time to create my 2D texture in the vtk file.

Thanks for your help !
