The CRG Virtual Environment (CVE)

CVE is a distributed multi-user virtual reality system, current features of which include:

networking based on IP multicasting;
support for the new extended spatial model of interaction, including third parties, regions and abstractions;
multiple users communicating via a combination of 3D graphics, real-time packet audio and text;
extensible object oriented (class-based) developers API.

The current version of the CRG Virtual Environment (CVE) is also referred to as MASSIVE-2 in some papers.

Availability

We expect to make a developers version available (initially for SGIs only) around the middle of February 1997. A port to Windows NT 4 is expected around April 1997. This will be to allow other researchers and interested parties to try out the system and build their own applications (on a non-commercial basis).
