1. A method comprising:

  • receiving a 3D-data stream depicting a first participant and a live environment of the first participant;

    rendering a common virtual meeting space having a virtual window for display of the first participant;

    rendering a first perspective projection stream of the first participant and the live environment of the first participant from the received 3D-data stream from a first virtual viewpoint within the common virtual meeting space, the rendering the live environment of the first participant using depth cues derived from the received 3D-data stream to enable perspective changes as a function of changing viewpoint, wherein the changing viewpoint is altered by rotating a view about an axis perpendicular to a floor and approximately parallel to an axis of a viewpoint source; and

    a transmission unit configured to transmit the rendered first and second perspectives for display;

    displaying the rendered first perspective projection stream in the virtual window for the first virtual viewpoint;

    rendering a second perspective projection stream of the first participant and the live environment of the first participant from the received 3D-data stream from a second virtual viewpoint within the common virtual meeting space; and

    displaying the rendered second perspective projection stream in the virtual window for the second virtual viewpoint.
