This week in OpenSim Dev – week ending Saturday 9th October 2010 October 11, 2010

Posted by justincc in opensim, opensim-dev, opensim-news, secondlife, twiod, virtual-environments, virtual-worlds.

Hello everybody.  This is a summary of the last week of development in OpenSimulator.  Except where otherwise specified, the changes described here appear only in OpenSim’s cutting edge Git ‘master’ branch. Please do not attempt to use code taken directly from ‘master’ in any production environment.  Sometimes this in-development code may not work or may even cause data corruption. If you are not a developer or tester, please treat this summary instead as a preview of what will be coming up in the next release. The latest official release is OpenSim (released on Saturday 11th September 2010).

The letters and numbers in brackets after some entries tell you the latest git commit to which they apply.

This week in OpenSim ( ab4be3f – cf61cf7 ).

General news

  • None this week.

Features & bug fixes

  • Melanie ported the Warp3D map tile renderer from omfOS.  This produces main map tiles of higher quality than the current rendered.  However, it is still considered experimental.  If you want to try it then set MapImageModule = Warp3DImageModule in the [Startup] section of OpenSim.ini (cb6e403).
  • Latif Khalifa contributed a patch that stops texture download failing if the viewer requests a packet with just a single byte (0dd4071).


  • No news items this week.

I am interested in hearing some more about Warp3d. I have googled it extensively but cant find out anything at all about it.

Does this mean that at last the map in opensim will show a reasonably correct arial view of the grid like the one in SL? Or is it the same map image as now, with incorrect prim shapes/sizes/colours, only sharper?

LOL… I want to know how excited to get about this.

Any info or pointers to info about this would be much appreciated. If anyone has a screen shot of it in use that would also be great.

Hi, I am researching for my Phd thesis and for that i really need to have the new opensim 0.7.1, because i need, among others, the media on a prim feature. Can you tell me when is it going to be released?

4. justincc - October 11, 2010

@Ener – I was on holiday and it was good :). Too good really – now I could do with another one!

@Bob – You’re right, the Warp3D library is pretty obscure. Here are some pictures from smxy which show the comparison between that renderer and the existing one.


I’ve heard that image generation still suffers from memory leakage but I can’t confirm this.

@Carlos – I’m afraid that I can’t give a timeline for a 0.7.1 release. However, I would expect it to happen before year end.

Warp3D is a C# .NET port of idx3d by Peter Walser. After some searching, I managed to locate him and jhurliman got him to re-license it under apache2.

with Warp3DImageModule, leave maptiles off, or else you will get an error. Warp3DImageModule can’t write JPG2K files (maybe fixed in later git repository)…
