<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I have a performance problem when I use vtkExtractSelectedIds with including the containing cells. I was studying the code and found a strange for-loop in the block below (vtkExtractSelectedIds.cxx v5.10, line 870). The
loop variable j is used both in the 1<sup>st</sup> for-loop and in the 3<sup>rd</sup> for-loop. The first for-loop’s j value is never used, but it gets reset to a low value every time the if-statement above the 3<sup>rd</sup> for-loop is true. I suspect this
is not intended.<o:p></o:p></span></p>
