<p>Hi Jakob,</p>
<p>Yes, your assumption is correct. Although, many the filters in ITK are capable of streaming, in which case not all of the image buffer is allocated.</p>
<p>HTH,<br>
Matt</p>

Dear all,<br>
<br>
First I have to apologize my first post this morning which was sent as<br>
html by accident :( . Sorry!<br>
<br>
I am very new to ITK and have a probably very simple question I could<br>
not find a clear answer for using google and the standard<br>
documentation (I also skipped through the Doxygen documentation, but I<br>
was not able to dive into the code as deep as the answer to my<br>
question would require :( ).<br>
<br>
3D data typically requires large amounts of memory - in the orders of<br>
100MB - 1000MB . It is typically not a good idea to allocate data<br>
ranges that large as a single big chunk of memory. So I wonder: If I<br>
set up a large 3D image with ITK - is the memory split up internally<br>
(like volume slices or whatever)? Or does ITK try to do something like<br>
(probably a bit oversimplified, but it should make clear what I mean)<br>
:<br>
<br>
float *p = new p [1024*1024*1024];<br>
<br>
?<br>
<br>
Many thanks for clarification and best regards,<br>
Jakob<br>
