[Rtk-users] Few questions about FirstReconstruction.cxx

[나윤호]

Hi everyone.

I am studying RTK with FirstReconstruction.cxx.

right now I am visualizing every step to understand it.
(visualize using view from itkwidgets)

and I have few questions about it.

first,
when I visualized ConstantImageSource I could see rectangular shape
by clicking X, Y, Z plane. but I couldn't see in 3d volume shape.
Is it a bug?

and second,
what is RayEllipsiodIntersectionImageFilter?
I visualized the output after constantimagesource
going through RayEllipsoidIntersectionImageFilter.
the shape was like a curved cylinder.
I also saw docs
<http://www.openrtk.org/Doxygen/classrtk_1_1RayEllipsoidIntersectionImageFilter.html>
but
I still don't get it.
someone give me an intuition please.

Best regards.

Yoonho.
