Sharing camera position, orientation, and target #15
Description
Activity
During the IIIF Annual Conference 2023 the week of June 5 2023, there was discussion of potential requirements and attributes for camera annotation items:
- Needs a "look-at" target, which could either be a 3D point selector or a painting annotation URI (for referencing a camera to a 3D model, label annotation, etc. as the look-at target), which determines the orientation/directionality of the camera view
- Needs a FOV property, defined as a floating point degree value similar to Three.js
- Needs a 3D position property
- Common camera specification properties like near limit, far limit, and aspect ratio are left to implementation and considered out of scope
- Specifying a camera is optional, and not necessary
- It should be possible to specify multiple cameras, to provide functionality for switching between views
- Currently unknown how shifts or transitions between cameras should be documented (CSS?), or if how camera view shifts are accomplished should be considered out of scope
As a museum digital exhibit visitor
I want to obtain a URL that loads the 3D scene at a particular viewpoint
So that I can share an interesting detail of an object with a friend
