OpenSim and Second Life GIS Retrospective – in the works

Published by under SL In General

Next week I plan to be on a panel at the Virtual Edge Summit 2010 in Santa Clara on Monday 22 Feb. Inspired by the style of a presentation by State of California GIO Mike Byrne at last month’s BAAMA.org educational session, I will try to prepare an Ignite-inspired talk for Virtual Edge. Since the virtual environment space almost demands it, I will use a film rather than a slide stack to structure my speaking.

The film is mostly cut, and a draft is uploaded in HD – for your perusal. If you want to hear my words try to keep pace with the film, consider attending Virtual Edge Summit, either in person or through one of its virtual channels. Hope to see you there!

If you have the bandwidth, please view the film in HD–I spent most of the past weekend cutting original FRAPS takes at full resolution so that the presentation could stand up to 1080p HD.

OpenSim: and now, a word from the Founder [Second Life]

Many thanks to Singularity U, director Matt Rutherford, and to Randall Hand who brought it to my attention After chatting at SLCC 2009 this past summer, I appreciate the immediacy of this lecture. OpenSim is discussed around minute 37 (video is available at 720p HD, and is just over 51 minutes long.)
Discussion of augmented reality, and mirror world creation in Second Life and virtual world simulators, just after minute 44.

It’s hard for me to listen to the entire talk just one time and retain the best explanations – but clear and current they are. In a virtual environment, immersed in near-infinite possibilities, Rosedale may no longer be guiding the Second Life ship, but I believe he remains the compass needle

A visit to ScienceSim Geography regions – OpenSim with turbo boost

I don’t have much to say about these regions that hasn’t been written already, and my views have been less aesthetic than Shenlei’s.
But in the interest of boosting the bandwidth by which I can share OpenSim, I’ve invested in a much newer Adobe Premiere Elements than I’d been using for the past five or so years. It’s a gas to have it multi-thread while rendering, and I have direct-to-FLV write. Trying to share as much of the motion and fidelity via YouTube as I possibly can, I’ve crafted a video resolution that is a multiple of my Hippo / SL viewer screen. The FRAPS video direct to AVI (sorry, it’s Win XP) is 1600 x 1140 @ 10 fps. Yup, those are video frames. In the interest of surviving an upload, I’ve rendered them highly time-compressed, with output at 1515 x 1080 @ 15 fps. As of tonight there’s no sound, no intertitles, just the rushes.
oops, if I read the YouTube Instructions for best formats, I should have trimmed the width to 1440, which is a multiple of 16.
Also, I have more direct upload options now with Premiere 8 than I had with my (recently demised) copy Premiere 1.0. Go Figure ;^)

While the Windows box grinds out the video print, I’m over here on Ubuntu blogging in a tab of 64-bit Chrome 4.0.249.43 and it is fine & fast.

For these videos, I visited ScienceSim Geography22_44 region and set the view to wide angle, then sat up at about 500 meters and watched the regions rez their terrain. For some folks, it will rank right up there with watching lead-based paint dry. For geography folks I’m hoping that these few minutes of sped-up video will convey, by dogged repetition, the primacy of regions in the provision of virtual environment simulators.

By the way, I’ve got a task: I need to find a better buzz word for the GIS community. I’ve been advised by some serious and well-intentioned (not to mention well-informed) folk that terms like “virtual” and “immersive” are actually boring to GIS’ers. So I’ll need to think about how to convey the concepts of “Mirror World”, “Multiuser Virtual Environment”, “Immersive Connected Experience”, “Third-Person Virtual World”, and related concepts into a catchy moniker. Hopefully, one that is not presently trademarked, either!

I’m trying to remain serious about this, but some of the options are treacherous. Geography in Social Media has a possibly awkward acronym; maybe it can be saved in recognizable form as “GIS for Social Media” or “Geography for Social Media”: GFSM
The term “3D Map with Me” is terse, slightly ambiguous

Here is the video chopped as it was when uploaded with 1515 x 1080 resolution. Problem with that is that by not preserving dimensions at a multiple of 16, and saving my viewer’s aspect ratio rather than the (standard since 16mm film) 4:3 aspect, my upload is clobbered into something perhaps suitable for a smartphone. So please consider this the Smartphone Version of last night’s rushes:

Then, once again with feeling, or at least with a little more rest, there is what I hope to be an HD-friendly moving vision of OpenSim, as it appears on the ScienceSim Geography regions. Yes! After it ripened on the YouTube servers for a few hours, I now see all the higher-res versions available. At 1440 x 1080, this is pretty close to what I see on my screen with a live Hippo viewer.

And after a day’s cogitation: anyone care to comment on the term: “Social Immersive Media GIS” as a moniker? Oops — I used “immersive” 8^(

Taking a break from OpenSim modeling, in planetarium

Published by under SL In General

The work on Point Reyes Station has more LiDAR data on tap, but this evening I’m taking a solar sauna in the Kepler planetarium. It’s a captivating display for both young and older eyes.

not all planetariums can be enjoyed from the center

A large planetarium has our solar system displayed dynamically
