• Updated and Added visuals to the examples listed below
• Added a WebAssembly html code sample in Read A PointSet and ITK/VTK Viewer reading in a vtk file fetched from external data cid

• Resources that were quite helpful in the comprehension of ITK process objects and data objects

The Architecture of Open Source Applications (Volume 2) ITK and of course the ITK Software Guide Books 1 & 2

For the Apply A Filter Only To A Specified Region Of An Image Example

I also spoofed a sequence diagram from architecture of open source applications (vol 2) ITK.
I was unsure that something like this would be more compelling for comparing input and output, rather than the simplified real-world data visuals.

The ITK/VTK Viewer implemented is just the default viewer, Kaibu provides the ability to run the example and edit the code. I should implement something of this before closing. Here is an example also of Sokol's visualization examples, perhaps a version of this would also be compelling to modify the existing cascading list page to display examples with existing images and/or itk/vtk viewers.

Should I make separate PR for work involved with setting up the ITK/VTK Viewer (with proper user interactivty) and then also updating the cascading list display?

@jph6366 thanks for the contribution.

No, ITK/VTK Viewer is no longer developed.

After infrastructure has been updated to fix builds, deployment, cascading list display, ITK-Wasm, there will be opportunities to contribute further.
