Getting Real World Terrains into OpenSim: A Tutorial by Brian A. White

This is recreation of a blog post by Brian A. White.  Brian’s blog went offline sometime in 2009, and recently it was suggested that someone republish this useful tutorial to make sure it can be found by search engines and does not someday completely vanish from the Internet.  So here it is.

Some of the links in this article are dead and not available in any existing archives.  I’ve left those in but crossed them out.  Fortunately these dead links are not critical to the tutorial, and I was able to update the other links that have changed since this article was written.  Brian, wherever you are, thank you again for writing this and I hope you are well.

OpenSimulator Community Conference 2013 – My Presentation and My Thanks to Everyone Involved

Attending the Opening Keynote Presentation

Attending the Opening Keynote Presentation

This past weekend I attended and spoke at the very first OpenSimulator Community Conference (OSCC13).  It was an amazing event full of outstanding presentations, great networking opportunities, and spectacular venues with tons of attendees.  It was also truly remarkable to see how far OpenSim has evolved and matured as a virtual world platform.

I’ve seen my fair share of online conferences, and this was the most professionally managed and engaging online conference I have ever attended.  To everyone involved in making this event a reality, thank you! 

And thank you all who attended my presentation.  I apologize for not having time to answer all your questions, but if you leave a comment on this blog post I will be very happy to reply.

Lastly, for those of you interested in me possibly restarting the Hypergrid Adventurers Club tours (I got a lot of positive feedback at the conference), be sure to join the HGAC mailing list and post that you’d like to attend a future tour.  If I see enough interest, I’ll definitely start them up again.

Please read on for my own presentation summary, video and downloadable slides.  You can also watch recordings of all the other presentations in the Conference Archives.

“Exploring the Interconnected: How Past Dreams evolve into Future Reality”

Join us to hear more about how dreams from the past can dramatically change and evolve into something completely new. In this presentation you will hear all about John’s initial experiences in Opensim while still working at Linden Lab, the creation and mangement of “Pathlandia,” initial explorations of the Hypergrid, and how it all fits in with what he remembers as Linden Lab’s original vision of an expanding Metaverse of self-hosted and interconnected virtual worlds.

ADDENDUM 9/10/2013: Be sure to read this blog post: “The Future of Conferences.” It’s an outstanding summary of the conference by Crista Lopes, the inventor of the Hypergrid and one of the conference’s main organizers.

Take care,
-John “Pathfinder” Lester

How to convert a prim-based object in Second Life or Opensim into a mesh object on your hard drive using the Singularity viewer

prim cube

ye olde prim

This is pretty cool.

The most recent version of the Singularity viewer (version 1.8.1) adds a particularly interesting feature:

  • Wavefront (.obj) and Collada (.dae) Export by Apelsin, Inusaito, and Latif Khalifa - Allows export of your creations into Blender, Unity3D and other modeling applications and game engines

This means you can now take a prim-based object from within Second Life or Opensim and export it to your hard drive as a mesh object (either .obj or .dae file format).

Heisenberg and Schrodinger are driving down the highway…

119710669026861758johnny_automatic_speeding_car.svg.hi

Heisenberg and Schrodinger are driving down the highway.  Suddenly, they see police lights in the rearview mirror.  After pulling over to the side of the road,  two policeman walk up to their car.

“Do you have any idea how fast you were going?” asks one officer.

“No,” says Heisenberg. “But I know precisely where I am.”

The policeman glares at him. “You were going 90 miles an hour, smartass.”

“Damn! Now I’m lost,” says Heisenberg, pulling out a map as Schrodinger starts to laugh.

The officer grows irate.

“Get out of the vehicle !” he yells, and begins searching the car while his partner pats down the two physicists.

After a thorough search of the vehicle, the officer returns to glower at the two scientists, now handcuffed and sitting on the curb.

“Did you guys know you had a dead cat in your trunk?”

Schrodinger sighs and rolls his eyes.

“We do now, idiot.”

How to create Avatar Sit locations on any object in a Jibe world in Unity3d

Here’s a short tutorial video that will show you how to create avatar sit locations on any object in your Jibe world.  It’s a very powerful and flexible system where you simply drag and drop sit locations onto anything in your multiuser Jibe world, allowing you to easily create collaborative meeting environments that encourage avatars to gather together in groups.

In this video, I also review how to avoid the accidental misuse of a script that could potentially cause your Avatar to fall through the floor.  Safety First!
