What is the difference of Glue when compared with video conference services?

Standard video conference services are limited to video and audio feed as well as watching documents on screen.
Glue is fully 3D spatial and Glue meetings take place in full 3D virtual meeting rooms/spaces. In the shared virtual meeting room/space the spatial presence and audio helps in team communications as for example multiple overlapping and simultaneous voices don’t cause confusions common to video conferencing between larger teams.

Shared common meeting rooms/spaces also have lots of free space for sharing and using more materials, presentations and screens than possible in video conference or even real world meeting rooms.
