<br>Hi all,<br><br>I am new to VTK. I have a volume to be displayed and annotated in such a way that user can scroll through the MPRs along x-axis. This means that as the user hits a key (or moves a slider in QT/fltk), a slice is displayed that is obtained by rotating yz plane along x axis by some step angle. Also, user should be allowed to draw a curve/spline on the display slice.
<br><br>I am not sure what is the best way to implement it. I am exploring vtkImagePlaneWidget for the purpose but I cannot figure out how to restrict it to display only the front side of the slices and disable user interactions (spin/rotate). Another option I thought of is to use vtkImageViewer2 by extracting the oblique slice and then displaying it in the image viewer. The problem is that then I have to handle the transformation of the clicked points to the image volume coordinate system.
<br><br>Please help me to find the best way to implement this.<br><br>Thanks,<br>-Uday<br><br>
