Can 3D visualisation be used as a basis for the in-vehicle navigation experience? Yes, it can!


Check out the video for proof:
• Built with Qt 6.5 + Qt Quick 3D
• Runs on Qualcomm SA8155P board + Android Automotive OS

But wouldn’t this be a problem: automotive systems are constrained in performance while running 3D as it’s plenty of data to be processed with the high quality satellite imagery & elevation information?
Not at all.
Our demo shows that the 3D rendering runs at 60+ FPS on current reference automotive boards.



While working with the Qt 6.5 & VR, we asked ourselves: Is it possible to become fully immersed in the car HMI? The answer, as it turns out, is “Yes.”

It might sound like science fiction, but we’ve done exactly that with the use of Qt Quick 3D XR (preview available; thanks to Qt for making it public!) and the Varjo XR-3 headset. We’ve transported ourselves “into” the HMI with our recent 3D-map navigation concept designed to experience route planning from a first-person perspective. The 3D map with satellite imagery and destination selection are now shown in virtual reality, while hand controllers are used to interact with the HMI.

Now, we’re working on enabling the full XR with pass-through capabilities so that our own hands are seen in 3D and controllers are no longer needed for HMI interaction.
