[Insight-users] Bug or error in Docu

[Lodron, Gerald]

Hi,

I found it in The ITK Software Guide Second Edition Updated for ITK version 2.4 (which is the last guide i found on web) on page 405 on table 8.13. I am quite new to ITK so I have to learn from anything. Does anybody know when a new guide comes out?

Best regards

Hi Gerald,

You may not be looking at the correct documentation page.

Here is what I find in the Doxygen page of the Similarity3DTranform:

http://public.kitware.com/Insight/Doxygen/html/classitk_1_1Similarity3DTransform.html


"The serialization of the optimizable parameters is an array of 7
elements. The first 3 elements are the components of the versor
representation of 3D rotation. The next 3 parameters defines the
translation in each dimension. The last parameter defines the
isotropic scaling."


The documentation of the CenteredTransformInitializer

http://public.kitware.com/Insight/Doxygen/html/classitk_1_1CenteredTransformInitializer.html

does not mention parameters.



    Please let us know where you found the text that you posted,


         Thanks,


                Luis

The strange thing is that all parameters except the last is 0, the last one is 1. That means that the scaling is 0 and the translation in z is 1 (referring to the doku)?
