NDI AR Camera App “ZIGCAM” was released!
Amazing useful technology, as it is with all things ZIG! Easy to get going.
It is great that you get all the AR transform data in as NDI metadata that gets turned into a big table with the XML DAT (if you leave the XML DAT as its default settings, otherwise the parsing doesn’t look like fun).
The 3D reconstruction (as point cloud) using RBG and depth is good too.
It would be good to have the metadata in JSON too, I’m not sure if that’s a limitation of NDI metadata.
And interesting how you are splicing the depth data with the RGB image in two ways.
NDI metadata must be XML, or, you can send TouchDesigner DAT tables via NDI metadata. So no JSON directly (unless you sneak raw text in as tables and convert back to text).
Thank you Greg.
Yes. NDI’s metadata must be XML.
I am concerned about the data size of the XML.
All of this is because numbers are also treated as strings.
I’m not sure if I should deal with it or not, because it’s a very dirty way of embedding information directly in images, and there is no defined way to do it.

Hiya,
I would like to know where can I get the tutorial on how to use the ZIGCAM with Touchdesigner?
Many thanks.

There is one here in english: Instancing Scene with iOS Face Tracking & TouchDesigner Tutorial - YouTube
And an introduction here in Japanese by @toyoshi himself: Introduction to ZIGCAM - YouTube
You can use Youtube’s auto-translate subtitles to get the main ideas.
