<div>Hi</div>
<div>I'm using three vtkImagePlaneWidgets for MPR and want to show the users which side of the plane they're looking at by introducing arrows in the middle of each plane. I'm using a cone and a cylinder to create each arrow, so I rotate them to point towards the plane. I can initially orient them correctly, and with the X and Y planes, this is sufficient, as I have them constrained to their axes. However, I am allowing the user to rotate the Z plane freely and cannot get the arrows to follow. I'm not sure if it makes more sense to do this during the creation of the arrow or by rotating it at the end. Any suggestions?

<div>Thanks,</div>
