Hi Sebastien,<br>
<br>
I tried your code. But the JVM Carsh is done while starting the app.
(JVM crash occurred While I press the button named "Dicom Multi
Planner Reconstruction (2D)" in main form).<br>
<br>
Here with I attached the java crash report. Any suggestion?<br>
<br>
Thanks,<br><font color="#888888">

Thanks for your suggestions. But that too not solve my
problem. If possible please send the whole code you
corrected.<br>
<br>
I have one more question that the same code works great in
windows and Mac. The problem is only with linux. Is there
any specific reason for that?<br>

<div>after some digging on what was going on with your
code, I've figured out that the memory leak you were
facing while using the VTK garbage collector was
mainly due to Java who keep a reference to any
graphical components that have been shown at some
point.</div>
<div><br>
</div>
<div>And in your case, your graphical frame keep a
reference to all your VTK objects (readers, filters,
renderers...). And because of that, VTK could never
release them.</div>
<div><br>
</div>
<div>In order to solve your specific issue you have to
have some code like that in
your WindowClosed listener:</div>
<div><br>
</div>
<div>
<div>private void
formWindowClosed(java.awt.event.WindowEvent evt) {</div>
<div> this.myVtkObjectA = null;</div>
<div> // [...] </div>
<div> this.myVtkObjectZ = null;</div>
<div><br>
</div>
<div> // but also remove the content of you
renderer that will keep</div>
<div> // the whole pipeline alive in the C++
layer if not cleared</div>
<div> </div>
<div> this.myVtkPanel.RemoveAllViewProps();</div>
<div>
this.myVtkPanel.GetRenderer().RemoveAllLights();</div>
<div>
this.myVtkPanel.GetRenderWindow().RemoveRenderer(this.myVtkPanel.GetRenderer());</div>
<div>}</div>
</div>
<div><br>
</div>
<div>As you may see for vtkPanel we have a similar
issue where its internal component won't be
released, and for now in order to reduce the memory
leak you need to execute the lines that I've put
above with "myVtkPanel". </div>
<div><br>
</div>
<div>But in a near future, we will add a Delete()
method on the vtkPanel to fully release its internal
objects so the code block could be reduced to
: this.myVtkPanel.Delete();</div>
<div><br>
</div>
<div>Moreover, Jeff and I are working of documenting
the Java part of VTK and providing some tools to
help identifying the cause of memory leak in Java as
well as improving the concurrency
support/management. So if some community member has
Java/VTK testing code that produce error/crash
because of concurrency or memory leak that could be
used as test, please send them to us so we can make
sure that the improvement that we are making will
solve your issue.</div>

I developed a simple
application that loads
a list of dicom images
and construct them as
3D. It works fine. I
call VTK from my Java
Application. If I
press a button from
main window, then the
VTK output will load
in another Jframe
window. Once I close
the output window the
VTK should release all
the memory. But i
doesn't do that. It
will be released only
when I close my main
application. </font></font></font></font></font><font color="black" face="arial" size="2"><font color="black" face="arial" size="2"><font color="black" face="arial" size="2"><font color="black" face="arial" size="2"><font><font color="black" face="arial" size="2">(Please

My Requirement is
while I close the 3D
window The VTK
memory should be
released. <br>
