[ITK-users] Conical or Solid Angle Iterator

Discussion:

Hello,

I am looking for a conical or solid angle iterator. I found something
similar to what I wanted in an older thread (see below). Does anyone know
of something that could help?

Thanks in advance,
Sarthak

Hi
It is already called in itkSetMacro(),
so if you change the filter parameters
using
e.g. SetMacro( Sigma, float );
The code generated by this macro
will set the new value and call
Modified().

Thanks, Will,
We want to store an indeterminant number of image feature objects such

as core atoms in a given block of physical space 10-20 voxels on a side for
analysis and spatial clustering. The blocks are in a regular isotropic
lattice, and we want clever

iterators that can sample ellipsoids, solid angles, etc. We have all

this stuff written in my VIA package, but not yet in ITK standards. We
don't want to duplicate what's available already in ITK.

Hi George-
Yes, but since I don't know what you're trying to do, I can't say
that this is the best way given what's there. Could you enlighten me?
Will
Dear Will,
Is there anything that would prevent us from making an itkImage whose

pixel type is a linked list? Damion Shelton (at Pitt) and I are working on
putting "core atoms" into the itk format, and this would be a very cool
approach to doing that.

Thanks,
George

Hi Sarthak,

the closest thing to a solid angle iterator is line iterator
<https://itk.org/Doxygen/html/classitk_1_1LineIterator.html>. You could
start from that and create a solid angle iterator. If you do so, it would
be good if you submitted <https://itk.org/Wiki/ITK/Git/Develop> the patch
to add it to ITK.

DÅŸenan

Hi Dzenan,

Thanks for the input. I will try to get this implemented and will submit it
if I am successful.

Cheers,
S
