Abstract: In an aspect, a computer-implemented method allows for navigation in a three-dimensional (3D) virtual environment. In the method, data specifying a three-dimensional virtual space is received. A position and direction in the three-dimensional virtual space is received. The position and direction input by a first user and representing a first virtual camera used to render the three-dimensional virtual space to the first user. A video stream captured from a camera positioned to capture the first user is received. A second virtual camera is navigated according to an input of a second user.

Abstract: Disclosed herein are aspects for resituating virtual cameras and avatars in a virtual environment. An aspect begins by rendering the virtual environment, including a first avatar and a second avatar. The virtual environment is rendered on a first device, belonging to a first user, and from a perspective of a first virtual camera controlled by the first user. The first avatar represents the first user at a location of the first virtual camera. The second user views the virtual environment from a perspective of a second virtual camera at a location of the second avatar. The aspect proceeds by repositioning the first virtual camera and the first avatar to a first location and resituating the second avatar to a second location. The aspect concludes by sending a message instructing a second device, belonging to the second user, to resituate the second virtual camera to the second location.

The virtual environment is rendered on a first device, belonging to a first user, and from a perspective of a first virtual camera controlled by the first user. The first avatar represents the first user at a location of the first virtual camera. The second user views the virtual environment from a perspective of a second virtual camera at a location of the second avatar. The aspect then provides several operations from the perspective of the first virtual camera. First, the aspect continues by determining a new location for a perceived avatar relative to the first avatar. The perceived avatar corresponds to the second avatar. Then, the aspect concludes by resituating the perceived avatar to the new location.

Abstract: Disclosed herein is a web-based videoconference system that allows for video avatars to navigate within the three-dimensional virtual environment. The system and methods provided include those for: (1) using zones in a three-dimensional virtual environment for limiting audio and video, (2) access control using zones, (3) access control of the three-dimensional virtual environment itself, and (4) controlling user connections in a three dimensional virtual environment.
