<div>Hi, Chuck...</div>
<div> </div>
<div>I am new in VTK... There is a way to use especific methods to Crystal Eyes in VTK? My goal is to make stereo images for Crystal Eyes. So, I display the same actor in two differents viewports, where each one has it owns camera... One camera I have to use the method Azimuth(5) to set the difference of the distance of the eyes... So, when I move the actor in one viewport, the other do not move together... I have to make this work! There is methods to Crystal Eyes already implemented???

On production applications the pair vtkOrientationMarkerWidget / vtkAxesActor was sufficient to me as I only needed a smaller viewport showing axes "perfectly alligned" with the object shown in the main viewport.
<br><br>It would be interesting to know if anybody on the list has had crash problems by sharing camera pointers among renderers.<br><span class="sg"><br> Luca</span>

<br>the same interaction on another renderer. We can listen on Interaction<br>events on the render window's interactor, but not quite sure how to<br>propagate it to the other renderers.<br><br>Mark<br><br><br>On Jan 9, 2008 8:52 AM, Sicilia Judice <
