Despite the popularity of third-party viewers such as Phoenix (formerly Emerald) and the disastrous design and usability problems of Linden Viewer 2.0, it has now become clear that Viewer 1.x is dying a slow death. The final release 1.5.2.818 of the Phoenix viewer is out, to be replaced by a new Firestorm viewer based on the 2.0 codebase, and there are similar plans for Imprudence to be replaced by the new Kokua viewer (whose name, I’m afraid, does not strike me as nearly as memorable – what’s wrong with Phoenix 2.0 and Imprudence 2.0 for names, rather than changing them just when they start to get well-known?)
This is, of course, a demonstration that the world of OpenSim grids, so dependent on the Linden codebase, is still very much semi-detached from development in SL, and interoperability will always remain a core issue.
One reason for this is mesh, coming soon (but we’re still not sure when) to a simulator near you. Look out, OpenSim and ModRex! Despite the latter’s support for mesh being far older than the Linden effort, ported back from RealXtend‘s version of the OpenSim codebase to a region module for OpenSim, it has never caught on. Although OpenSim developers seem to be working on mesh, it’s no longer clear if ModRex is the main plank of this effort. It still only works in standalone mode, not in grid mode. The pace of development on ModRex seems still to be incredibly slow, after an initial burst of activity, and it’s blog and web presence remains embryonic and dated.
The 1.x codebase can support some newer backported features such as Display Names (which is not likely to be complex code) but it will be increasingly difficult, and most likely impossible, to continue developing viewers that work for both OpenSim and SL without embracing the viewer 2.0 codebase. Incidentally, Display Names will not work on OpenSim, but apparently will on Aurora based-grids (see below). Hopefully, however, the terrible viewer design will be completely ignored. Even the developer of Kirsten’s viewer, which rather slavishly avoids any affront to Linden Lab by providing direct support for OpenSim (which is a simple matter of using the open source grid manager code from the Hippo viewer), has been critical of the Viewer 2.0 design. I should say, in Kirsten’s defence, that it is not completely impossible to use the present version of the viewer with OpenSim.
Meanwhile, new forks of the OpenSim server codebase are appearing, notably Aurora, which provides a great deal of core functionality that users have been crying out for. The new Kokua Viewer (a separate project loosely associated with Aurora, previously known as Imprudence) will support some of these extra features. At present, things like profiles, groups, search and web interfaces have to be hacked together once per upgrade, and database changes leave all of these side projects struggling to keep up with the OpenSim codebase.
OpenSim developers, after their huge success with Hypergrid, have managed to undo their own work by fracturing the community into no less than three mutually incompatible and often unreliable versions of what is the most fundamental part of the open metaverse. At present, Hypergrid is barely working at all, and it is a major victory to teleport off one’s own servers. Yesterday I finally managed to reach OSGrid (though it’s misconfigured locally, so that one cannot leave) using a test grid running Aurora, although I cannot do so with any revision of OpenSim 0.7.1-dev on which it is based. Admittedly the latter is development code, but many grids are already running it, including OSGrid. People were astonished to see someone arrive from the outside: one said it had been a year since they had known it to be working! Obviously, some of the unreliability is down to local server configurations, which is an operational problem. But why keep breaking Hypergrid with every new release? Why does it have to be so hard? This is no way to help grow the open source metaverse.
It seems that the OpenSim developers do not seem to see the hypergrid as a priority even though it is what makes people compare OpenSim grids to the Web and its rich competitor SL to the once-mighty AOL. At present, documentation and communication about OpenSim remain amateur and patchy. Of course, the developers make the blinkered ideological claim that they are NOT a competitor to SL, but such claims are often made by those who are manifestly failing to capitalise on their obvious strategic advantages. However talented the OpenSim developers are, they are terrible salesmen. And they are convincing nobody. Their user base certainly is competing with SL, even if they personally, as developers, are not. Remember, the user is queen – or even king!
Get it together again! All this fine work needs a bit more coordination, no?
