- pass-through: VR shows the real world through the VR headset cameras; no image from zmq or webrtc is displayed (even if enabled).
- fov: a small window in the center shows the robot's first-person view, while the surrounding area shows the real world.
- ego: a small window in the center shows the robot's first-person view, while the surrounding area shows the real world.
2. Enhanced Immersion
Adjusted the image plane height for immersive and fov modes to provide a more natural and comfortable VR experience
Adjusted the image plane height for immersive and ego modes to provide a more natural and comfortable VR experience
### V3.0 🏷️ brings updates:
1. Added `pass_through` interface to enable/disable the pass-through mode.
