</div>Yes, but that was long ago, and a test was added at the end of<br>
/Filtering/Testing/Cxx/TestPointLocators.cxx that was supposed to check<br>
for this.<br>
<br>
Please confirm that you are using a reasonably new VTK.<br>
<br>
I can't remember if it was VTK or ITK where the last remaining issues<br>
with the KdTree seemed to only occur when the two points were almost<br>
exactly the same distance from the trial point, so close that the error<br>
could be from calculations being made in float verus double precision.<br>
<br>
Your test looks reasonable but I've been awake for way too long and<br>
can't give it a thorough look.<br>
