[vtkusers] VTK slow to display 300 vtkArrowSource in real-time

[Olivier Ameline]

Hello, 

Thanks for your replies.

Indeed, I use too much actors and vtkGlyph3D or vtkGlyph3DMapper seems to be
the solution to my problem.
However, I don't see very well how to use it.

Which class to use to compute the array of positions/orientations ?

How to tell that one column gives the positions of the arrow source and the
other gives the orientation ?
