[vtkusers] Delete actor and release memory

[Nicolas Rannou]

Hi all,

I would like to delete/remove actors from my rendering window to free
memory.
The issue is that the memory usage doesn't decrease after removing/deleting
the actors.

>From my understanding, both following pseudo-codes should use the same
amount of memory.
But,
The first one uses: 15 Mb for 1000 spheres:
The second uses: 90 Mb for 1000 spheres:

How should I proceed in the 2nd case, to get back to the "original" memory
usage without actor?

Thanks,


Nicolas

//Create a sphere

//Create sphere

// mapper
vtkMapper* mapper ...
mapper->SetInput( sphere->GetOutput() )

// actor
vtkActor* actor...
actor->SetMapper(mapper)
mapper->Delete()

// Add and remove actor
renderer->AddActor(actor)
renderer->RemoveActor(actor)

// Delete actor
actor->Delete()
