Systems and methods are described for virtual and augmented reality. A position of a first user and a position of a second user in a physical space are received, wherein the positions are derived from detected infrared light from a plurality of cameras. An image corresponding to the first user is rendered at a first virtual position in a display device associated with the second user, wherein the first virtual position is determined based at least in part on a position of the first user in the physical space and on a determined viewpoint of the second user. An image corresponding to the second user is rendered at a second virtual position in a display device associated with the first user, wherein the second virtual position is determined based at least in part on a position of the second user in the physical space and on a determined viewpoint of the first user.
