I increase the ViewAngle parameter of vtkCamera.
Sure, you said it.

But It is different from issue I have.
I worry that a part or my actor disappear on Screen.
Not out of sight but in sight.(Screen = Window)
It happen 'Camera near Actor'.
the hiding is only not that there is Black plate front Actor.

Now I draw volume rendering object without MarchingCubes to Screen.
Is it bad ?
Now I use my vtkActor like vol.tcl or volSimple.tcl of vtkDemo.
It desen't happen in vol.tcl.

I think Something relation ClippingRange ....
I can't compose this problem ,
  I write(ren->GetActiveCamera()->SetClippingRange(1,1000);)
I can't write (renderer->ResetCameraClippingRange();)
 What this Method?,,,Isn't there it vtk 2.4 ?

I'm worried.
