"James Camerom screened 24 minutes of his highly-anticipated Avatar at the Cinema Expo in Amsterdam on Tuesday and scooper 'The Insider' witnessed the footage and sent us this exclusive report! The footage utilized the RealD XL Cinema System. The 3D presentation was on a 55-foot screen with nearly 10-foot Lamberts of light, delivering the largest and brightest 3D presentation at Cinema Expo.

I've just returned from a preview screening of James Cameron's hugely anticipated movie "Avatar" at the Cinema Expo in Amsterdam and I'm still feeling the after effects of this jaw-dropping experience"

Ray Kurzweil to Keynote This Year's SLCC

Here is extraordinary and transformational news: I just got word that Ray Kurzweil, the legendary inventor and futurist, will keynote this year's Second Life Community Convention in San Francisco, speaking on the benefits of virtual environments and virtual reality. "I think Ray Kurzweil’s speech will change the tone of this year's convention compared to previous ones," SLCC director Nexeus Fatale tells me, which is an epic understatement. Among the world's greatest technologists, Kurzweil has often spoke about Second Life in relation to the future of human society, in ways that stretch far beyond how we currently experience it.

Vuzix Announces World’s First Fashionable Sunglass-Style Video Eyewear with Revolutionary “See-Thru” Quantum Optics

Provides a 60-inch private video display complete with Virtual Reality and Augmented Reality capabilities and built-in noise-isolating earphones all in less than 3 ounces

Rochester, NY – January 5th, 2009 – Vuzix Corporation is thrilled to announce a ground-breaking addition to the video eyewear market: the Wrap 920AV. As the demand for mobile access to digital entertainment and information skyrockets, Vuzix has once again pushed the envelope. This portable big screen solution with Vuzix’ proprietary Quantum optics technology allows for a “see-thru” video experience in the form of a functional pair of sunglasses and is upgradeable with optional accessories.

The stylish Wrap 920AV functions with any media playing device with a video output and projects a virtual 60-inch screen, as viewed from 9-feet. The state-of-the-art lens technology also allows users for the first time to view 3D video content while seeing and interacting with the real world. This incredible blend of reality and computer generated content will transform the world of portable video while opening up the consumer to previously impossible “location aware” applications. An optional 6-Degree of Freedom tracking sensor and/or Stereo Camera Pair will enable users to upgrade their Wrap 920AV to experience virtual, augmented and mixed reality environments.

“The Wrap 920AV will not just change the portable video industry, but how consumers view and interact with information,” said Vuzix CEO Paul Travers. “From watching a Civil War video reproduction battle reenactment on the actual battleground to walking through the streets of New York City with an animated virtual tour guide, the possibilities are endless,” added Travers.

“As listed in 2008 at the Gartner Emerging Trends and Technologies Roadshow, Augmented Reality promises a paradigm shift in how consumers interact with news, entertainment and information,” said Vuzix Consumer Division Product Manager Ron Haidenger. “The Wrap 920AV is the first product at a consumer price point to deliver this game changing technology to the masses,” added Haidenger.

Additionally, Vuzix will be offering low cost optional prescription lens inserts to provide the perfect solution for consumers wearing prescription eyeglasses. A patent pending electronic Inter-Pupillary Distance system enables eye separation adjustment, ensuring that all users will have an optimal viewing experience. Amazingly, the entire system weighs less than 3 ounces.

The above is coming soon according to Vuzix but they just released is this:

The iWear AV230 XL+ delivers a virtual display equivalent to a 44-inch screen at a very affordable price.

With unmatched quality and performance, the iWear

Live Asset Updating - Torque 3D from GarageGames on Vimeo.In this video, GarageGames showcases the new Live Asset Updating functionality for Torque 3D.
Below clipped from: Ralph Koster's Website:

"Torque 3D looks to be challenging Unity for the 3d game in a plugin market; check out this feature on their home page:

Deploy any Torque 3D project from the World Editor to a web browser in seconds with our web publishing options. Torque 3D supports all major browsers and operating systems, including IE7, FF3, OS X and Chrome. Games perform at 100% native speed, with no performance cost, completely in your browser.

Both solutions, of course, require that the plugins that host the native client be widely deployed, which is the biggest challenge. The gap between something like Flash or Javascript, and something like this, is measured in the hundreds of millions of installs. Of course, what you get for the native renderers in the plugins is desktop quality graphics.
The push on the other side, of course, is to upgrade the graphics in a form basically native to the browser, so you don’t need a plugin at all, or if you do it’s one you already have (because you visited YouTube once)."

and fom the last comment by Brett Seyler of GarageGames

" I agree. No magic bullet exists yet, and I doubt one will appear in the next 12-18 months. I think this is an awkward, but promising transitional period for games one the web / games in the browser. The streaming problem is a big one to tackle technologically, but there are good solutions for that."

VR leaves the Cave - Again

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Fri, 26 Jun 2009 10:00:00 +0000

For 40 years Virtual Reality (VR) has not gone mainstream. In 1966: Ivan Sutherland invented the head-mounted display suggesting it was a window into a virtual world. VR has been a nich market used by those with R&D budgets, Intel, IBM, the Defense Industry and the NSF. It just never caught on and entered the mass market through at least 3 Gartner hype cycles and even product introductions. Yesturday 1989 - the Mattel Power Glove. Today - the Wii controller, Tomarrow - Microsoft Natal?.

Virtual Worlds or MMOG have been around as long, since the 80s.

Now the hype is Augmented Reality but remember it was 16 years ago, 1992: when Tom Caudell coined the phrase Augmented Reality while at Boeing helping workers assemble cables into aircraft. The idea has been there, even the technology and yes the Best programmers and scientists have been onboard, but........ That Killer App still illudes.

3D Conferencing System Allows for Virtual Light Saber Duels

Researchers at the University of Illinois at Urbana-Champaign and Intel have created a system that can support collaborative physical activities from different geographical locations.

“We can capture motions of the human body in real time and bring them together on a big screen,” says Ahsan Arefin, a doctoral student currently involved with the project.

The project called ‘Tele-immersive Environment for Everybody’ or TEEVE hooks up two off-the-shelf 3D cameras to a PC with a Firewire port. A gateway server at each site sends and receives the different video streams using standard compression techniques. A renderer is used to project the virtual interactions on a big screen monitor, creating a real-time virtual 3D effect. It’s like web conferencing, but with a virtual reality twist.
The idea has applications beyond gaming. It can be used in business, sports and medicine, says Arefin. An experiment by the University had two dancers from different locations dancing together on a large screen.
Arefin says TEEVE can work on PCs with high-end Intel processors.

“Our goal is to make the system portable and easily deployable because of its use of off-the-shelf components,” he says.

SnowGlobe & HTTP texture

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Thu, 25 Jun 2009 15:10:00 +0000

Clipped from the SL wiki
Objective of the http-texture Project

The initial idea of the project is to allow the viewer to point to any image file of any format anywhere on the internet, pull it using the http protocol and use it as a regular texture anywhere textures are used.
This involves a bunch of moving (and new) parts:

Using any file format as textures (instead of just j2c)
Pulling image files using HTTP (instead of UDP)
Getting resources from any host (instead of just the LL asset server)

This is a rather ambitious and wide ranging change. As of today (March 24th, 2009), the main plumbing has been implemented with the following caveats:

Only jpeg images are supported as another file format
Such images must be loaded at once (no progressive rendering yet)
Except for jpegs specified with an "http://" URLs, all other images are still using the old fashion protocol
There are still quite a bit of crashes here and there... Don't use such a build for your regular SL activities (search for bugs logged against http-texture branch in PJIRA for more info)
Quick Thoughts:

Imagine the implications:

Freeing up the LL servers from storing, retrieving, cashing, & sending textures/ OH and those nasty adult textures, we dont do them.
and
those pesky IP rights issues. take down notices.
and
Working in China. Iran, and Australia is easier if The Powers That Be can block your offensive textures and not our game, our product offering.
~woot~ I can hear the boardroom presentation of this now.

OH better yet

More $$ for "The Lab" as well.
New SaaS products..
Sell asset services, like land. Imagine all content creators becoming responsible for their own Rez times/level of service.
How about?
You can pay extra (a new Premium Content Creator account) to have LL serve/store assets for you
or
Don't pay up and content creators (IP owners) can always just get and pay for their own asset server(s).
Ballgame changed..... Pay for it to come out, not 10L to go in...

Maybe... We will see.

Into the Deep end of the Pool

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Thu, 25 Jun 2009 12:59:00 +0000

We have been exploring and talking to many people "outside the box" lately. Being that I am located in a US city that was once the Silicon Valley of the 60s, residents here have a hard understanding just how important it is to think outside the box.

Kodak just retired Kodachrome(tm) and If there ever was a poster child for those that can't think out of the box and see how technology can change a whole landscape this would be it.

We have been posting clips and snip on ~woot~ the past few days, most would not interest readers here who have a different focus, but there is one thing I will share...

Intel: The people with the worst graphics chips, giving a place to ATI and Nvidia is no sleeping giant, nor have they failed to date to capitalize on their research like another "High Tech" company from this city did after they invented Ethernet, the mouse & yes the desktop metaphor.

Intel acquired and now owns Havok, and acquired another group "Offset" and it's team, I believe in 2008, Since then, they have been making great progress on a game (still codenamed “Project Offset”).

Just "a game" maybe modest as I look at it:

It supports Collada, as do many games now, but it has simultaneous real time games editing and play (think Second Life) and yes they have just a few resources to make 3D work. Here is a link to their features page:

Out of the Box - Impressive 3D by Swedish Developers

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Mon, 22 Jun 2009 13:47:00 +0000

All the C3 products are based on high-resolution aerial photography with carefully calibrated cameras. For every picture, the cameras position and angle are calculated with extremely high precision, using an advanced navigation system. This is what enables C3 to give each pixel its geographical position with decimeter accuracy.

C3 Maps are calculated directly from images and is not dependent of any laser scanned data (LIDAR).

For rapid production scaling C3 have choosen to use a standard camera system that can be used inside standard aircrafts. With this approach C3 is contracting flight operator partners world wide to acquire the requested images. To clone a camera system for production in a specified area is manageable within 2 months and thus new areas can be captured rapildy.

The Start of a Better Sim

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Thu, 18 Jun 2009 17:32:00 +0000

Akira Sonoda accidentally discovers the CHANGED_ANIMATION event in Opensim, and fosters the first generation of lag-free animation overriders (AOs).

LSL open source AO's like ZHAO

"have one common flaw which is imposed by Second Life's design: They produce Lag! The reason: They have no clue when to change the animation! Therefore they do some polling triggered by a timer event in order to read the currently running animation which will be overridden depending on the configuration read from a configuration notecard.
But in OpenSimulator based grids this can be done much more elegant because thanks to Melanie, one of the developers, a new event is available is available in OpenSimulator, which tells the script when an animation has to be changed!"

via: MaxPing.org

Add changes like this to patches by Intel engineers working on OpenSim code and hopefully soon a region in OpenSim will support hundreds of avatars with much less lag then a similar sim in Second Life does.

Almost Soup - Teleporting Out of Second Life

JeanRicard.Broek@yahoo.com (JeanRicard Broek) — Fri, 12 Jun 2009 13:06:00 +0000

As you may know we believe OpenSim is stable enough to be an alternative to Second Life. Add to Open Sim RealXtend and Modrex technologies, the ability to import and view content from other programs like Google Sketchup using Ogre and you can see some key ingredients to the future of a new 3D Web being developed.

.. It is not soup yet?
... No.

I believe for the 3DWEB to take off faster then Twitter 4 primary ingredients are being chopped, diced and are now stewing.

Open standards & protocols with open source software services (Apache like servers) for the storage & transfer of real-time information of all types between servers and the viewer's PC, TV and cell phone. This includes being able to teleport between sites and view 3D content as easily as you just found and opened this blog page.
Easy import and exchange of content, be it music, a building design or avatar hair from multiple established creation tools, from Gimp and Blender to high end Autodesk products to Google's Sketchup. This will open a giant pipeline of content and draw talented creatives waiting just outside the current myopic game & media studios and virtual world walled gardens like Second Life.
The establishment of content markets of all type, from free like Google Warehouse, to auction sites like E-bay, to Checkout & pay catalogues like XStreet, Renerosity, Dell & Apple Apps.
Instant access & viewing, just like opening web page now. This may be a viewer that contains the browser, or 3D in the browser, or even better a replacement for the 30 year old Windows desktop metaphor. Maybe all of the above.

How close are we? Who is the best cook? I could give a rats ass, We are starving on crumbs.

We can smell the soup, taste the cooks spoonful, read recipes, but the soup is still cooking. So today I would like to point to two blog posts regarding Point 1 above - Teleporting - I will followup in the future with the other points... Take note, I do not promise not to eat the meal before it is served.

Worried CAD vendors

Google is 100% behind a 3D internet experience. A 3D enabled Chrome is now being advertised on the front page of Google, coincidental with the release of the O3D programming interface (Open 3D).

Every web designer and developer now needs to ask themselves “can I afford to ignore this?” or a more pertinent “how long have I got to exploit this before I’m left behind?”

Anyone who profits from CAD in any way, either as a user or seller, has a lot to be worried about right now. SketchUp is growing in its user base (and edu base) at an unprecedented level. I was recently at an Autodesk Revit training event where more of the audience questions revolved around SketchUp than the actual product we were there to learn about. And the industry is worried for one very simple reason. They’re starting to lose customer loyalty, and with it their market share. “If you can design a NASA space station with $400 SketchUp Pro, why can’t I use it for my project too?”

Introduction to 4D Research
by Martin Fischer @ http://www.stanford.edu/group/4D/

Traditional construction planning tools, such as bar charts and network diagrams, do not represent and communicate the spatial and temporal, or four-dimensional, aspects of construction schedules effectively. As a consequence, they do not allow project managers to create schedule alternatives rapidly to find the best way to build a particular design. Extending the traditional planning tools, visual 4D models combine 3D CAD models with construction activities to display the progression of construction over time.
