The problem with the traditional technique of texturing the inside of a sphere with a 360 equirectangular image or video to form a background in a virtual scene is that it looks like a painting of reality when viewed in a VR headset. What’s missing is a sense of depth. The Samsung 360 Round looks like it could solve that problem by live streaming a 3D 360 feed with 4096 x 2048 resolution per eye. Hopefully this would mean that the background would merge better with virtual objects in the foreground.
The downside is the cost ($10,500!) and the PC requirements for live streaming – a couple of GTX 1080 Tis (total about $1500) and an i7-6950X CPU (around $1500) makes for a pretty expensive setup. And I am not sure if I understand this correctly but you might need two PCs with that setup. Yikes.
