This is an old project I rebuild for a VR headset like the Oculus Quest. Rendered in 8000 x 4000 per eye in record time on SheepIt RenderFarm, a distributed render service for free with limitations.

You can navigate with Firefox Reality from panorama to panorama with the controller and trigger pointing at the floating spheres. Keep in mind that this is a static stereo equirectangular image. You need to turn around in place but you have no real 3d space.
