<DIV>the problem I'm facing is that when I close the <FONT size=2>QVTKWidget</FONT>, the memory allocated for rendering the volume and not the memory allocated for the reader , still not released even I delete all the actors, Mappers and the vtkVolume itself.</DIV>
<DIV>How can I find the Memory that VTK allocate for rendering the volume or how can I free it ?</DIV>
<DIV> </DIV>
<DIV>this is how I proceed in just before closing the <FONT size=2>QVTKWidget</FONT>:</DIV>
<DIV> </DIV>
<DIV><FONT color=#0000ff size=2>
<P>delete</FONT><FONT size=2> []((</FONT><FONT color=#0000ff size=2>unsigned</FONT><FONT size=2> </FONT><FONT color=#0000ff size=2>char</FONT><FONT size=2> *)data2->GetScalarPointer());// data2 is a vtkStructredPoints *</P>
<P>data2->Delete();// this is the only way I found to release the memoryu allocated for the reader.</P>
<P> </P><FONT size=2>
<P>rndr3D->RemoveVolume(vlm);//rndr3D is vtkRendrer*</P>
<P></FONT><FONT color=#008000 size=2><FONT color=#000000>vlm->Delete(); //vlm is the vtkVolume*</FONT></P></FONT><FONT size=2>
<P>rndr3D->Delete();</P>
