Hi all,

I am rendering a Ct image using vtkRenderer, now I want to add a circle over
the image. Suppose if I set the radius of the circle to 5cm it should cover
5cm on the image as well.

How to seup the coordinate system properly?

I tried using Renderer.ViewToWorld(), my app hangs!

Thanks

Jothy
