The 3D Tiles format is to designed specifically for large scale 3D models rendering in WebGL, especially geo data. At the moment even a simplest untextured city scale data of few thousands buildings easily goes over multi gigabits, and the actual usage of RAM is twice of that. That's a lot better to display without crush as before 3D Tiles, but still a long way to go, Thank you.
