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.
