Crashing Rezzable Alpha Open Sim Grid

Posted in Building with tags , , , , on February 17, 2009 by Wizzy

My marching orders are to try to crash Rezzable’s Alpha Open Sim Grid.  So I set about to do that with a passion once scripting was turned on on my two regions.  Somehow Foolish Frost fixed the script engine, commenting that Rezzable Open Sim doesn’t use the Xengine script engine.  In that case, I would expect this grid to behave differently from the Reaction Grid.  So far, all behavior seems very similar.

Next, I tried to “stretch” the object as large as I could, given the limitations of the Linden Lab viewer.  Initially I had a lot of problems getting the viewer to allow me to stretch.  It was acting kludgie and I think it might have had to do with the sim stats.  Check out the sim speed:

After I relogged, I was able to “stretch” (after the selection tool accepted all 2956 prims).  With the ten meter limit on prim size however, it didn’t stretch much.

After I stretched it to maximum, I moved it straight down to ground level.  This is easier said than done, because you’ve selected about 3,000 prims to move and the sim creaks and groans and complains.  It’s not done easily, let me just say that.

Remarkably, with almost 3,000 active scripts on the region, I was able to rez a prim and create and compile a script afterwards.  Only one anomaly was noticed – I couldn’t “take” a prim that I should have been able to.  Instead I had to delete it and then restore it.  This small anomaly might count toward “crashing” the sim, but so far Rezzable Alpha has been resistant to my banging on it.  Will continue to do so tomorrow.

Building on Wizzy sim @ Rezzable Open Sim

Posted in Building with tags , , , , on February 13, 2009 by Wizzy

RightAsRain Rimbaud gave me two regions to build on the Rezzable Open Sim.  I’ve been testing it out and it seems to be almost identical to the Reaction Grid.  I can get to the Rezzable grid direct using a new shortcut for the SL viewer, but I would really like to use the Hippo Open Sim viewer.  The main reason for this is that the viewer allows building 256 meter objects (provided the server code allows it.)  I actually was able to log in with the Hippo viewer once.  But not since then.

I did a little testing and found that scripts weren’t working on my Wizzy region.  This is consistent with the behavior I observed at Reaction Grid.  With Open Sim 0.6.1 the script engine keeps breaking and is unreliable.  The engine can’t seem to handle much of a load.  On Reaction grid it would slow down and break after I rezzed about 3000 objects with active scripts.  I selected and “Inactivated” the scripts, but even so the script engine broke down.  Some regions continue to work though.  The behavior is inconsistent.  This is the issue: http://opensimulator.org/mantis/view.php?id=2853

Also the LSL function ( llRemoveInventory(llGetScriptName());) that can be used to delete out the active scripts from the objects doesn’t work in Open Sim 0.6.1 or is not enabled.  This is a serious bug and if fixed could be a workaround for the major issue above.

I went to the Rezzable 5 region and found that scripts were working there.  So I rezzed a complex geometric object (Compound 5 Octahedra) and added a rotation script, then copied it and rezzed it on Wizzy.  And there it is now.

MiniMap Reveals Symmetry

Posted in Building with tags , , , , , on February 7, 2009 by Wizzy

I rezzed only the vertices of the new “Concentric Circles” rotation of the E8 Polytope on the new Soror sim at Reaction Grid.  Then stretched the vertices out to fill the sim.

The scale is so big (200 meters in diameter) that my computer had a hard time rendering them so that I can see the symmetries.  I was looking for that axis that reveals the concentric circles.

By accident, I happened to look at the mini map.  Lo and behold, there is the symmetry.  The order is revealed from the seeming chaos:

Not Possible in Second Life – NPISL

Posted in Building with tags , , , , , , on February 6, 2009 by Wizzy

G2 Proto gave me four regions on the Reaction Open Sim Grid to build and display my E8 Polytopes.  So I rezzed the newest E8  “Concentric Circles”  on the Wizzy sim and the older E8  “4_21 Gossett”   on the Xeno sim next door.  I stretched them so that they almost fill a whole sim each.

This is not possible in Second Life due to the stretch limitation of ten meters.  The circular base under the E8 in the photo above is 200 meters in diameter.

This is the way the four sims appear on the Open Sim map.  Obviously, there’s a problem with the rendering program, but it gives you an idea of the scale.

Reaction Grid (http://reactiongrid.com) seems to have a working relationship with Intel and Microsoft.  According to G2 Proto, Intel has developed a strategy to increase the concurrent avatars on an Open Sim to 150.  If true, this would be the long-awaited solution to the laggy sim.  And he says that Microsoft is bringing their Open Sims to the Reaction Grid.  This may mean some good traffic to see the E8 Polytope works that I have done in collaboration with Desdemona Enfield.

Go and check it out and set your draw distance to 512.  I recommend downloading the Hippo Open Sim viewer (from http://reactiongrid.com).  Then you will have to add the Reaction Grid to the list of Grids.
