title: Paraview: How to draw arrow in a point cloud
body: <p>I would like to know if paraview can manage this scenario:</p>
  
  <p>I have a .txt file composed for this fields:
  x y z vx vy vz</p>
  
  <p>The first 3 parameters represents the location of the point in the space. The last 3 parameters are the components of the unit vector that represents a direction.</p>
  
  <p>I would like to display the point cloud and for each point display the arrow that indicates indicates a direction using (vx,vy,vz)</p>
  
  <p>I am sorry if it is a basic question, I recently started using paraview and I am a litle bit lost.</p>
