Perphaps you can invert the second transform. Concatenate with the first and see how far away from identity you are ?<br><br><div class="gmail_quote">On Tue, Feb 24, 2009 at 7:51 AM, Oscar Esteban Sanz-Dranguet <span dir="ltr"><<a href="mailto:oesteban@die.upm.es">oesteban@die.upm.es</a>></span> wrote:<br>

Hi all,<br>
<br>
I want to sum to tranformations in order to know if the result is equal
to a third one. I was guessing if simply operating over <a href="http://www.itk.org/Doxygen38/html/classitk_1_1Array.html" target="_blank">itk::Optimizer::ParametersType</a>
will do the work.<br>
<br>
Specificly I have to compare three Rigid3DTransform, so I thought to
compare the three versors and the three translations.<br>
<br>
Is that the correct way to resolve the problem?<br>
<br>
Thank you all in advance,<br>
<br>
Oscar Esteban<br>
