I'm running the following code on Windows 7 (both x86 and x64), and have noticed the following memory usages. I think this implies some memory leak in the render call to VTK. Can someone please let me know if they see this as well, and if so how to fix it.<div>
<br></div><div>Thanks</div><div><br></div><div>Here are my results<br>0 Renders -- 9.852 M<br>1 Render -- 29.28 M (I'm not sure if this jump is to be expected)<br>10 Renders -- 29.76 M<br>100 Renders -- 30.404 M<br>
