[vtkusers] Problem freeing memory

[Gennady Khokhorin]

Cameron,
I experienced the same problem in the past and ended up with smart
pointers:
{

    vtkSmartPointer<...> myObj = vtkSmartPointer<...>::New();

}

My guess some vtk items creates silently child objects down the
hierarchy tree.

 

Happy programming!

Gennady

Subject: [vtkusers] Problem freeing memory


Hi,

I'm currently trying to free the memory taken up by my DICOM loading
function (vtkDICOMImageReader). The problem is that I call Delete on
everything that I've instantiated, but the ~700MB still remains in the
RAM.

The vtkVolume that I read the object into is global, so I've got a
button that removes it from the renderer and then deletes it, like so...

   this->pvtkRenderer->RemoveActor(this->volume);
  this->pvtkRenderer->RemoveAllViewProps();            //for good
measure :)
  this->volume->Delete();


What else would I have to do? I've called Delete on everything in the
load function, and I've deleted the volume object itself..... so.... I
don't know.

I realise that the Delete funtion only decreases the counter for that
object, but all i'm doing is loading in a DICOM object and deleting
it.... so nothing else should be using it.

Maybe there is a Cleanup function or something??



Thanks,
Cameron.
