[vtkusers] Please Help: Problem to display 2D image in volumeusing vtkActor/vtkPlaneSource

[Thomas - Kuiran Chen]

Hi Andre,

For that question, unfortunately, I didn't get any reply from the VTK group.  Seems like not too much people are interested in that particular appliation, :-).

So I finally I got my own solution to it after trying numerious methods.  My solution was not using the vtkPlaneSource because the transform for it never got right.  Instead, I converted the 2D image from vtkImageData to the vtkPolyData and created another vtkActor specific for that image, then displayed it with the proper transform.  

It worked fine for me.  I think vtkPlaneSource  is supposed (or designed) to be a ideal and elegant way to handle this, but somehow it has bugs.

Are you also working on displaying a 2D ultrasound slice inside a ultrasound volume?

Hope it helps and Good Luck!

Hi Thomas,

On the internet I found a post of you with the above subject.  It is 
exactly the same problem I am facing at the moment. Did you receive any 
usefull comments on your post and did that help you to do the 
visualisation? If so, please could you send me those solutions?

Thank you in advance,
