Electrum Spiral @ Caerleon Art Collective

Posted in Building with tags , , , , , on April 11, 2009 by Wizzy

I’m working on this new thing.  It started out as a sketch on graph paper in RL.  Then I turned it into a 3 foot by 3 foot painting:

Then I rendered it in prims in SL in 2D.

Then I turned it into 3D in SL.

Soror Nishi asks if I could put some steps up to the fractal.

At the suggestion of Desdemona Enfield, I knocked out some of the cubes and this is the result:

We put those cubes back in and it starts to look like a twisted Mondrian painting:

I asked Xenophile Neurocam if he knew anything about this fractal.  Because it’s definitely not the Golden Spiral.  It’s not derived from a Golden Rectangle and it doesn’t encode the Golden Ratio or the Fibonacci Series.

My good friend Xeno is so smart.  He said look into something called the “Pythagoras Tree.”

Bingo!  Discovered by Albert E. Bosman (1891-1961), a dutch mathematics teacher, in 1942.

This version is different from all other variations I’ve seen of the Pythagoras Tree, so I’m calling it an “Electrum Spiral” because it’s definitely not the Golden Spiral.  Electrum is an alchemical mixture of Gold and Silver and the other five classical metals.

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.

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.
