Moving and rotating OARs [UPDATED]

[Update 20091216: ZOE v 0.1 has been released. You’ll find a manual and the download link here.]

…and some filtering too

Opensim Archives (OARs) are nowadays the standard tool to share and interchange full Opensim regions. Justin Clark-Casey, the core Opensim developer in charge of OARs, has lately added merge functionality to the loading of OARs. This means that you can merge (i.e., add) the contents of an OAR file to an existing region, without deleting its contents. This opens a plethora of interesting possibilities, but it also is the source of a lot of new problems. What if I’m very interested in merging an OAR with one of my existing regions, but I’d prefer the new contents to be placed differently from their original position? For example, I can be given an airboxed level at 1000 meters, but I might want to put it at 2000 m (for example, because I already have contents at 1000 m). Or I might be interested in an OAR with (say) some nice palace and gardens, but it’s located in the NE corner of the sim and I’d like to install it in the SW part of the sim.

At present, the “load oar” command does not allow for this kind of transformations. Indeed, it’s debatable whether Opensim should include code for this kind of application at all, or whether such manipulations should better be handled offline.

0705 - ZOE- A test run

In this article I present a very simple (and highly experimental) OAR manipulation tool called ZOE (for Zonja’s Oar Editor :-)) that implements some very basic forms of filtering, relocation and rotation for OARs as a whole.
