Analyze and describe requirements around annotation in a 3D environment

[JulieWinchester]

Taken from @azaroth42's IIIF/api#1992

Requirement: A document analyzing and describing the requirements around annotation precision in a 3d environment. For example, is a cube enough, or do the use cases require arbitrary volumes?

Rationale: Annotation is a core functionality of IIIF, and there aren't 3d annotation targeting specifications we can simply reference, thus knowing the requirements explicitly around annotation is very useful to set out in the right direction. This is needed for both comment annotations (look at this arm of the statue) and positioning models in the space (this statues goes here, that statue goes there).

This was discussed during the pre-TSG working group meeting on October 5th, with the general sentiment being that this document be short (1-2 pages). Content could include a short summary of some current existing solutions to this problem and the basic scope of any IIIF work to be done - i.e., what aspects of 3D annotation the IIIF 3D TSG might hope to address or would definitely not expect to address.

As the TSG group has now been certified, this document should be linked in this story (if it was created) and the story can probably be closed as either completed or not planned?
