In my VTK-based application, I have three intersecting (initially perpendicular) vtkImagePlaneWidgets. Is there an easy way to compute the intersection point between these three planes in VTK?<br>
Searching the archives, I found that similar questions were asked in the past, but I was unable to find a clean and satisfactory answer.</p>
<p dir="ltr">I can compute the intersection point by myself if necessary, but if VTK offers a simpler alternative, then I will go for it!</p>
<p dir="ltr">Thanks in advance for your comments.<br>
Best regards,</p>
