OpenSim Development

Today the Open Simulator group announced the formation of Overte Foundation, a 501c(3) entity that allows tax free donations from the USA. The foundation will hold the rights to the code that makes up the simulator, the server side of many virtual worlds. It appears the main purpose is to clean up licensing issues and head off future problems. But, what does this do for the OpenSim user? To understand we need to know a bit about the Open Simulator Project and what is changing.

One change is a uniform license is being created for those contributing code to the project labeled; Contributor’s License Agreement (CLA). Quoting the Foundation, “Under this agreement, each OpenSimulator developer, including the core developers, will continue to retain copyright over their code but will also grant an explicit copyright license over their contributions to the Overte Foundation.

The current licensing is BSD, which does not require an author to state they have all necessary rights to contribute code to the Open Simulator Project. The CLA changes that. Nor does BSD grant a right to distribute the code to an explicit entity. The new licensing will deal with that too.

OpenSim and LIBOMV

In OpenSim grids it is common to need to move things we have built from grid to grid. LIBOMV ( libopenmetaverse ) is a new tool for doing just that. It is a DOS Command Line (text commands and no in-world view) type program. So, you may want to look at Astra Viewer for a viewer … Read more

OpenSim Astra Viewer Review

Astra Viewer
Astra Viewer

The main developer of Astra Viewer is Siana Gearz. (See comments for a correction) Posting in SLUniverse’s forum Siana wrote:

Oh and never mind my fork of Astra, forget it, it’s for private OpenSim/AuroraSim installation only, It’s a special purpose version of Imprudence.

Siana was writing in a thread about the Singularity Viewer to answer someone question about Astra. If you have questions about Astra, contact Siana.

So, Astra is not a Second Life Viewer or at least not intended for use on the SL Grids.

For OpenSim Use

If you are playing or working on OpenSim then download a copy of Astra. Astra Viewer Download (broken) Update: Astra Viewer Download (from Google 11/2011) which eventually leads to a Singularity Viewer download.

USE: Astra Viewer Download (1.6.0.2) – See: Astra Viewer 1.6.0.2 Download Review

The web site is mostly empty. Update: 11/2011 the site is gone.

OSGrid Update Week 7

Some time Tuesday we should get a new version of the server software. Several things have been fixed. One big one is; throttling, the ability to evenly split up bandwidth usage. That prevents a visitor with a fast Internet connection and high viewer settings from taking a disproportionate amount of the available bandwidth, which lags other visitors. A common problem for home based regions.

One must update their INI files to use throttling. The actual lines that need to be in the opensim.ini file can be found here.

There has been a teleport problem causing crashes. Tuesday’s release should correct that problem. This has been an annoyance for some time. I look forward to having my teleport units working again.

OSGrid Update Week 4

OSGrid has been upgrading the backside of the grid. My regions have been offline most of 2011’s weeks 3 & 4 as the database converts to a new format. The latest release of the simulator software has some changes. These are the ones I found interesting.

Terrain Files

The sim software can now handle terrain files made using Terragen. Once the grid is back up I’ll be checking out the new file type as it imports and exports Terragen (.ter) format. Also, this list of supported files types for terrain files was updated. Hopefully it will be easier to work with terrain in Photoshop and L3DT. Thanks Kevin Cozens.

Editing Terrain or Raw Files with Photoshop

Photoshop
Camera Raw Open

I needed to edit a terrain file for one of my regions in OpenSim. Trying to smooth the terrain with the terrain editing tools in viewers just was not working. Whether one is targeting OpenSim or Second Life it is the same process. Photoshop is where the challenge is, getting a terrain.raw  or terrain.r32 file open in Photoshop. This article shares the information I found and avoids a lot of the link rot that has set in on this subject.

Terrain and Camera

When searching Google one quickly realizes there is more than one type of RAW file. RAW files are used for images files created by many scientific applications… and especially digital cameras. When searching for terrain tutorials on Google use the negative term –camera (minus sign/dash and a word) to exclude information about camera raw files.
