Recently there have been multiple users noticing NDOF (space-navigator) isn't working as they would expect.
- T60768: 3D Connexion Space Mouse Pro doesn't works in Blender 2.8 (win32)
- Bf-committers: 3d connexion support
It seems most other software (including Space-navgator driver demo) works differently to Blender's defaults, making it seem as if something is broken.
This design task is collect these differences and update Blender to fit typical NDOF useage for other 3D software,
or - if there are good reasons to keep Blender working as-is, to support these features as preferences.
This list is based on user feedback may need updating, add comments if it misses anything.
- Constraining Motion
Blender: doesn't allow panning by default, instead modifier keys need to be pressed to pan for example.
Other Software: doesn't constrain motion, similar to always being in walk-mode (without having to enter/exit walk mode).
Open Topic: Would we orbit around the center of view (as with MMB orbit), or the view-point origin (as with walk mode). I'd assume we would default to orbiting around the view center.
- Orbit Origin
Blender: Orbits around the view center.
Other Software: orbits the selection center.
Note: Is this the case for most/all other 3D software with NDOF support?
- Ability to transform objects
Blender just doesn't support this at the moment, adding it to this list for completeness.
