[vtkusers] Handling of vectors in VTK

[Aurelien Marsan]

Dear VTK users,

I would like to have more informations about the handling of vectors in 
VTK.

It seems to me that it is only possible to define a single PointData 
Array as a vectors. Is that really the case ?
If yes, that lead to some major issues when using vtkTranformFilter : 
only the array set as active Vectors is correctly handled. Could you 
then tell me the right way to achieve the rotation ?

Thanks in advance for your answer,

Aurélien Marsan
