[vtkusers] vtkArrowSource rotation issue

[Markus Ott]

Hi,

i have a problem rotating vtkArrowSource. A instantiated arrowSource
points from [0, 0, 0] to [1, 0, 0] with it's origin at [0, 0, 0]. If i
want to rotate this thing to [1, 1, 1] what is the correct way to do
this rotation?

Obviously I need a rotation of 45 degrees around the y and the z axis.
Doing this via my actor works for each axis perfectly but putting it all
together the arrow doesn't point to the desired location:

actor.RotateWXYZ(45, 0, 0, 1);
actor.RotateWXYZ(45, 0, 1, 0);

What is the right way of doing this? I just don't get it!

Thanks so far.
