Sometime, it just isn’t worth it. Such is my new view of tier, in the context of what matters to me with immersive 3D and GIS. For about six months I’ve continued my hold on some land in the classic Stanford sim of Second Life, without quite being able to work out the boundary changes to just barely squeeze in a 1:1 scale model of a single large building. Even if I had been able to get the parcel into the shape that I needed, I still would not be able to model the structure’s dome with a prim that naturally had the large radius required. Not everyone is trying to model a Frank Lloyd Wright public building; perhaps the land can be better used by someone else with an architectural focus.
I’m scaling back ownership this week to the tier-free 512 square meter level in Second Life. I’m also building up a freshly configured Ubuntu 9.04 Jaunty Jackalope 32-bit server (dual 3.4 GHz Xeon – 4 GB, HP DL360 G4) to do some more serious sort of work with OpenSim. In the past five months I’ve developed some terrain data that can handily provide 1-meter postings over more than 500 square miles. With that much to publish, I really need much, much more than 1/8 of a sim, even a suberbly cool sim like Stanford.

So if anyone reading this has use for a great 7520 (< 1/8 sim) mainland location in Second Life with over 40 meters of terrain sculptability, it’s available for L$20/square meter. Discount available for OpenSim community members or known GIS people. With the world’s economy as challenged as it seems to be, I’ve decided that it’s time to focus on where things matter most, and for me now that’s OpenSim more exclusively.
The terrain forge was fired up tonight, and the virtual dump truck made dozens of runs into immersive reality. Compared with OpenSim where terrain megaprims can be fine-tuned to the precise size requirement, in Second Life I must back-calculate the scale from actual terrain sculpties. Apparently my trusty Gene Replacement 40-meter spheres can be induced into 35.70-meter terrain blocks, using the method I developed for use in Level 2 OpenSim build of UC Berkeley. This version 0.9 of the terrain made some mis-calculations about the ultimate size of the top sections of each sculpted prim. Look for better scale control with version 0.91 soon!

There’s some progress on a couple of project fronts. I’ve started assembling some USGS terrain for a 1:10 scale Level 1 build that could involve more OpenSim regions than I’ve ever stood up on one machine before. Snapshot of progress is here, with a goal of 304 OpenSim regions for the model. I expect that the OpenSim server will be re-imaged and a new build attempted in the next couple of weeks.

The site design for the Marin Civic Center build in Second Life Stanford region is also moving along with its target 1/8 region (two SL acres) based on RL terrain and building at 1:1 scale Level 3 build. Progress sketch below:

A bit more can be reviewed by looking at the PDF of the same map here.cc_topo_20090211
Finally, a sky tag has been added to the space above the build. It is visible as a streak to anyone who visits SLURL.com by a mouse roll. The Stanford region now has a large “MARIN” visible in its upper reach, squarely in the middle of the ancient Second Life Outlands.

Only the four-story Administration building (wing), not the two-story Hall of Justice. I’m tired so I’ll let the shot speak for me.

To me, it’s mildly amazing to realize that F.Ll.Wright’s design fits so snugly in 1/8 of a Second Life region at 1:1.00 scale. The Civic Center Administration building is a Real-Life building that can be visited, providing an easy way to get a true RL immersive sense of its scale. Building at 1:1 scale in Second Life for the first time, this has been my first experience of transferring that awareness into the multi-region contigous space of the very beautiful Second Life. Sure, I’ve built large areas at 1:1 using draped LiDAR data, but to have a rather large single building (or at least its footprint for now) in context with existing builds that I’ve seen for months, well, at the moment SL seems larger than I’d thought. That shift in my perception of SL scale may be the contrast between flying (quite fast as it turns out) around 40 to 100 OpenSim regions versus walking around the site and knowing how long it takes to traverse the RL building.
Anyway, check out the build’s progress at secondlife://Stanford/100/235/30
