[vtkusers] Actor depth problem

[KS Jothybasu]

Hi,

I am rendering a image with vtkimageviewer2 and adding a rectangle over
that. Even though I render the image first and add the rectangle to it the
rectangle over the image is nos visible. What could be the problem. Here is
my cutter code from which the rectangle is obtained froma cube.

See the pic attached.

 def AxialCutter(self,Object,SliceNo):
         cutPlane=vtk.vtkPlane()
         cutPlane.SetOrigin(0,0,SliceNo)
         cutPlane.SetNormal(0,0,1)

         cutter=vtk.vtkCutter()
         cutter.SetCutFunction(cutPlane)
         Color=Object.GetProperty().GetColor()
         cutter.SetInput(Object.GetMapper().GetInput())
         cutter.Update()

         cutMapper=vtk.vtkPolyDataMapper()
         cutMapper.ScalarVisibilityOn()
         cutMapper.SetInputConnection( cutter.GetOutputPort())

         color=Object.GetProperty().GetColor()

         planeActor=vtk.vtkActor()
         #planeActor.GetProperty().SetOpacity(0.5)
         planeActor.GetProperty().SetColor(color)
         planeActor.GetProperty().SetLineWidth(2)
         planeActor.GetProperty().SetAmbient(1)
         planeActor.GetProperty().SetDiffuse(0)
         planeActor.GetProperty().SetSpecular(0)
         planeActor.SetMapper(cutMapper)
         return planeActor

Thanks

Jothy
