What is the hypergrid?

The hypergrid is an extension to opensim that allows you to link your opensim to other opensims on the internet, and that supports seamless agent transfers among those opensims. It can be used both in standalone mode and in grid mode. The hypergrid is effectively supporting the emergence of a Web of virtual worlds.

The basic idea for the hypergrid is that region/grid administrations can place hyperlinks on their map to hypergrided regions run by others. Once those hyperlinks are established, users interact with those regions in exactly the same way as they interact with local regions. Specifically, users can choose to teleport there. Once the user reaches the region behind the hyperlink, she is automatically interacting with a different virtual world without having to logout from the world where she came from, and while still having access to her inventory.

The hypergrid started as a external project, but it is now included in the standard distribution of OpenSimulator.To run your OpenSimulator instance in hypergrid mode, please seeInstalling and Running Hypergrid.

Hypergrid Versions

• Hypergrid 2.0 - current Hypergrid with greater security controls for region operators
• Hypergrid 1.5 - past Hypergrid version with greater asset security and expanded services
• Hypergrid 1.0 - the original Hypergrid described below

Teleporting via the Hypergrid

The structure of a hypergrid link is similar to a web page link : [hop://]<hg-host>:<hg-port>[/<region-name>][/x/y]. Examples:

"hop://cc.opensimulator.org:8002/keynote 1""hop://grid.mydomain.com:9000"

The first example is the Hypergrid address of a region named "keynote 1" on the grid at cc.opensimulator.org that has port 8002.

The second example gives only the hg-host and port. In this case, the destination region is the default region setup for that grid, as specified in the [GridService] section of bin/Robust.HG.ini (for grid) or bin/config-include/StandaloneCommon.ini (for standalones).
