<br><br><div dir="ltr">HI, <div><br></div><div>basically I just need 1 component out of the vectorData (and later on select other component).</div><div>As u see in my previous email, the vtkDataArray reads all the data (from qflow velocities) and put it in the vtkDataArray, So basically, vtkDataArray hold all the data, with the information that it knows that it has 3 components (it is defined in the file). Also I can not use another reader, because I'm loading VTI files, which requires a different reader. I hope this will answer your question. </div>
