Paraview: How to draw arrow in a point cloud

I would like to know if paraview can manage this scenario:

I have a .txt file composed for this fields: x y z vx vy vz

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.

I would like to display the point cloud and for each point display the arrow that indicates indicates a direction using (vx,vy,vz)

I am sorry if it is a basic question, I recently started using paraview and I am a litle bit lost.

ParaView is the perfect tools for this task.

  • Open ParaView
  • Open File -> youFile.txt
  • change the "delimiter" to " "
  • set haveHeaders correctly if you have header or not in your file
  • Apply
  • Filters->TableToPoints
  • X -> x, Y -> y, Z -> z (considering your file has headers)
  • Apply
  • Filters->Calculator -> xv*iHat+yx*jHat+zv*kHat, Apply
  • Filters->Glyph
  • GlyphMode property-> All Point , Apply
  • Done !
