[vtkusers] Tr : Release Memory after rendering

[Mohamed Ben Reguiga]

Hello Japrin,
the method reduces the amount of the memory allocated but doesn't releases it completely.
I've tryide what following :
//delete the memory allocated for the reader : it's a vtkstructedPoints in my case
delete[]((unsignedchar*)reader->GetScalarPointer());reader->Delete();
//then I deallocate the tables created for computin gradiants et displaying the volume
//vlmMppr : vtkVolumeRayCastMapperif
if(vlmMppr->GetGradientEstimator() && vlmMppr->GetGradientEstimator()->GetGradientMagnitudes())delete[](vlmMppr->GetGradientEstimator()->GetGradientMagnitudes());
I know it's really a little bit uggly , but the method i'(m followin is the most efficient for memory release after rendering.
but never , all the memory was released.
tahnk you for your help. .

Hi,Mohamed Ben Reguiga:

I'm facing a similar problem.Could "void vtkActor::ReleaseGraphicsResources(vtkWindow *)" take effect?
