Hi, <br> I am new to vtk and I am trying to draw a freehand path with vtkImageTracerWidget on loaded vtkImageData. I set the View Properties for imagetracer from my vtkImageViewer2's image actor as follow<br><br> m_imageTracerWidget->SetViewProp( m_imageViewer2->GetImageActor( ) );<br>
<br> The imageTracerWidget can be drawn correctly in front of background image for the first half of total slices of volume. For example, if the total number of slices is 100, the tracerWidget was drawn in front of the slices for slice 0 to 50 but it was drawn behind the slice for slice number 51 to 99.<br>
Please kindly provide me how to solve this issue for vtkImageTracerWidget.<br><br>Thanks and regards,<br>Thiha<br>
