Disclosed herein is a web-based videoconference system that allows for two-dimensional screen sharing within the virtual environment. In some embodiments, data specifying a three-dimensional virtual space. The three-dimensional virtual space comprises a plurality of participants and an avatar representing each of the plurality of participants. A presentation stream is received from a first client device of a first participant. The presentation stream is mapped onto a three-dimensional model of a presentation screen in the three-dimensional virtual space. A selection of the presentation screen is received from a second participant. A two-dimensional view of the presentation stream is rendered to the second participant.

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.

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 orientation in the three-dimensional virtual space is received. The position and orientation 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.

Disclosed herein is a web-based videoconference system that allows for video avatars to navigate within the virtual environment. The system has a presented mode that allows for a presentation stream to be texture mapped to a presenter screen situated within the virtual environment. The relative left-right sound is adjusted to provide sense of an avatar's position in a virtual space. The sound is further adjusted based on the area where the avatar is located and where the virtual camera is located. Video stream quality is adjusted based on relative position in a virtual space. Three-dimensional modeling is available inside the virtual video conferencing environment.

Disclosed herein is a web-based videoconference system that allows for multi-screen sharing. In some embodiments, data specifying a three-dimensional virtual space is received. The three-dimensional virtual space comprises a plurality of participants and an avatar representing each of the plurality of participants and three-dimensional models of a plurality of presentation screens. Multiple presentation streams may be shared on different presentation screens simultaneously.

Disclosed herein is a web-based videoconference system that allows for video avatars to navigate within a virtual environment. Various methods for efficient modeling, rendering, and shading are disclosed herein.
