This Week in OpenSim Dev – week ending Saturday 5th December 2009 December 8, 2009

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

Hello everybody. This is a short summary of OpenSim development for the past week up until the end of last Saturday.  The letters in brackets after bug and feature points are the Git revision identifiers in which the work appears.  We only give the first 6 characters of each revision but this should be enough to identify it.

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.  At particular points in time 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 0.6.7 (released on 14th October 2009).

This week in OpenSim ( 4338f4 – 8d196d ).

General news

  • Testing continues on the ‘release candidate 1‘ stage for OpenSim 0.6.8.  This was branched from master on 23rd November 2009 though it will incorporate selected bug fixes from the master line.  If you’re familiar with OpenSim, are comfortable with building it from source code and would like to contribute to the release process then please follow the instructions on the mailing list and get testing!

Features & bug fixes

  • Adam implemented support for the upload of terrain files in the .bmp, .raw, .r32 and .r64 formats via the client’s estate tools (30fe88).
  • Teravus fixed a limitation where prims larger than 10 x 10 x 10 could not be physical.  To prevent “deep think” (where too many interacting collisions can cause the simulator to take hours to compute the physics for each frame), he also added a configurable maximum_mass_object setting in the [ODEPhysicsSettings] section of OpenSim.ini.  The default setting should be fine for most people (781db4).
  • StrawberryFride contributed a patch that allows terrain maps to be loaded directly from a URL on the console (e.g. terrain load http://myserver.org/terrains/myterrain.r32). (c0f3a4).
  • Melanie reduced viewer updates when linking and delinking prims.  This should make linking a little more efficient (1a6958).


  • No notable changes this week.
