[vtkusers] How to project a 2D shape of a 3D object on vtkImagePlaneWidget?

[Huanxiang Lu]

Hello everyone,

 

I am a newbie of vtk. Currently I use the vtkImagePlaneWidget to visualize
my vertebrae image and I put a 3D bounding box on the each vertebrae. The
thing that I want is to have a 2D projection of the 3D bounding box on my 2D
image plane in the vtkImagePlaneWidget. 

 

I tried to get the image plane as a vtkPlane object so that I can find the
intersection between the bounding box and the image plane. But it seems it's
impossible to get a vtkPlane object from the vtkImagePlaneWidget, because
there is no certain method. Is there anyone who can tell me how to realize
it?

 

Thank you very much!
