Display a 3D model, specifying position, orientation, and scale

[edsilv]

As an Online Exhibit Curator

I want to display a single 3D model, specifying the initial position, rotation, and scale

So that I can draw attention to a particular point of interest

This user story partly includes what one can already accomplishe with IIIF Presentation API 3.0 - using a "model" annotation type to display a single 3D model in a IIIF viewing experience. Specifically, it's currently possible to place a single 3D model in a single 3D space. What is currently not possible is to use the IIIF manifest to specify the initial position, orientation, and scale of the model, but this is crucial in order to correctly indicate and demonstrate the model.
