Things about SL

#SL News 3 Week 42

Blake Sea and Le Tigre

You probably remember the region crossing problems sailors and pilots had with the previous Havok Physics Engine update. Putting different versions of Havok on adjacent regions creates problems. Havok was never designed for use across multiple versions of Havok. It’s use by Linden Lab™ is the only known use that encounters that problem. So, we will likely have crossing problems with each update of Havok.

With the addition of Pathfinding and possible other gaming features to Second Life™ we are likely going to see more updates of Havok, but fortunately, less crossing problems. ‘More’ is like a couple a year.

Region Organization

Some weeks ago the Lab tried placing adjacent regions in the same or adjacent servers, physically adjacent servers. This made what Oskar Linden described as a ‘MASSIVE improvement’ in performance. Now it is standard operating procedure to keep the regions and servers organized.

Mesh Deformer Update Week 42

by

Darien Caldwell is working on what I call the second phase of the Mesh Deformer. A bug in the Deformer has come up in that process. I suppose this is a minor bug… it is easy enough to work around. But, one does have to work around it and know about it. I talked with Darien in the Open Source user group meeting, which Oz Linden rescheduled then didn’t make it to. 😛

Darien has posted an explanation of the bug in STORM-1716, which anyone can see and most can post to. This is the comment:

Scripting & Server News Week 42

by

For the release candidate on Le Tigre we have some new information that comes from the wiki release notes just recently updated. Some of those are:

Havok Update

The Havok Physics Engine updates to version 2012.1 in the release candidate. In week 35 I reported that this version was coming. At the time we had just updated to 2010.x, I think. This update enables Havok’s terrain optimized that simplifies the physics shape of the terrain for improved performance. This feature can be disabled by region owners and estate managers with the Region Debug Console command “set optimize_terrain false“.

Havok Physics

Some are reporting vehicle crossing are slower.

llGetSimStats

llGetSimStats() has yet to show up in the Linden Scripting Language (LSL)  pages of the wiki. Fortunately the release notes say:

Currently, this function accepts only [[SIM_STAT_PCT_CHARS_STEPPED]] as its parameter, which returns the % of Pathfinding characters skipped each frame, averaged over the last minute.  The returned value corresponds to the “Characters Updated” stat in the viewer’s Statistics Bar.

New Info from the Firestorm Team

by

No not a viewer release. Jessica has posted on the Firestorm blog about what is going on with Firestorm and their development effort. See: Status update.

New Firestorm Region in OSGrid

In my Kokua article: Kokua Beta Status & Review, I wrote about the rates that developers were releasing versions of their viewers. Jessica is explaining their release philosophy and how that will be changing.

Included is a list of coming features in the next release. Some we have seen in preliminary versions in other TPV’s. I expect the Firestorm release to have features with more polish and improved user interface.

The Team is also focusing on stability. Firestorm is currently the most stable viewer used with Second Life™. Jessica says they have even more stability fixes.

#SL News 1 Week 42

by

This Tuesday we got a roll to the main channel. This is the package that was on Blue Steel. This is the code to improve performance for Large Groups. It is not the Large Group Editing changes that Baker has made. Those changes are in a package still stuck in QA.

It has been quite since the roll out. That usually means things are working as expected.

Sever-Scripting Meeting September 2012

Magnum

Is going to continue to run the same package it has had for the last couple of weeks. This is a package that adapts the simulator to the new hardware. It contains various configuration changes for the Denebian OS running in the region servers. I have no information whether this is identical to last week or some configuration settings are changing. Whatever the case, it is expected users won’t see any difference.
