* 1. an ''external''- or ''file URI'' fully replaces the current scene and assumes `pos=0,0,0&rot=0,0,0` by default (unless specified)
|
|
*
|
|
* 2. navigation should not happen when queries (`q=`) are present in local url: queries will apply (`pos=`, `rot=` e.g.) to the targeted object(s) instead.
|
|
*
|
|
* 3. navigation should not happen ''immediately'' when user is more than 2 meter away from the portal/object containing the href (to prevent accidental navigation e.g.)
|
|
*
|
|
* 4. URL navigation should always be reflected in the client (in case of javascript: see [[here|https://github.com/coderofsalvation/xrfragment/blob/dev/src/3rd/three/navigator.js]] for an example navigator).
|
|
*
|
|
* 5. In XR mode, the navigator back/forward-buttons should be always visible (using a wearable e.g., see [[here|https://github.com/coderofsalvation/xrfragment/blob/dev/example/aframe/sandbox/index.html#L26-L29]] for an example wearable)
