Researchers at Purdue have published some research on using pulsed near-infrared lasers to create 3D scans of arterial structures, allowing detailed scans without requiring cuts.
The laser generates molecular “overtone” vibrations, or wavelengths that are not absorbed by the blood. The pulsed laser causes tissue to heat and expand locally, generating pressure waves at the ultrasound frequency that can be picked up with a device called a transducer.
Our last selection of this week kicks off with a look at the Oil age, with three infographics from Post Carbon Institute, Wondermark and UNEP. Then, Online Schools approaches the issue of the increasing cost of fueling our cars, and, last but not least, JESS3‘s take on the future of solar energy.
One week from today, Dr. Martin Banks of the Visual Space Perception Laboratory of UC Berkeley will be hosting a free webinary on user issues in 3D Displays. He’s got a wide range of issues to discuss that are relevant to everyone from 3d production to human vision experts.
A variety of user issues.
The temporal protocols used in stereo 3D and how they affect perceived flicker, motion artifacts, and depth distortions
Head roll, vertical eye movements, and visual discomfort
Visual-vestibular conflict and nausea
Vergence-accommodation conflict
Vergence: the inward or outward turning movement of the eyes in convergence or divergence;
Accommodation: the focusing of the eyes to make the image on the retinas sharp.
Vergence and accommodation in natural viewing; coupling
Vergence and accommodation in stereo displays
Optometric measures of discomfort
Evidence that vergence-accommodation conflict with stereo displays causes discomfort: blurry vision, tired eyes, and headache
The effect of viewing distance
The effect of the direction of the conflict (content in front of the screen or behind?)
Maintaining comfort in different viewing situations
Relating these findings to current practice

Fans of Daffy Duck, Elmer Fudd, and Tweety Bird are in for a treat as the late Mel Blanc will voice a new trio of cartoon shorts in fabulous 3D airing in theaters soon.
The three new shorts are all directed by Matthew O’Callaghan and executive produced by WBA’s Sam Register (The Looney Tunes Show, Teen Titans, Ben 10). The producers are Spike Brandt (The Looney Tunes Show, Duck Dodgers) and Tony Cervone (The Looney Tunes Show, Duck Dodgers).
First first short, “Daffy Duck’s Rhapsody” features Daffy Duck and Elmer Fudd, and is scheduled to release November 18th before Happy Feet 2. After that is a Sylvester the Cat & Tweety Bird comic, and later a new Wile. E. Coyote cartoon. Sadly, no Bugs Bunny.
AMD’s newest promotional video shows CATIA through their benchmark suite “CATBench” on a new AMD FirePro V7900 with GeometryBoost and the NVidia Quadro 4000. The results are startling.
The CATbench benchmark uses a number of different models ranging in size from an engine block to an entire nuclear submarine assembly. It performs a set number of pans, zooms and rotations in shaded plus edges graphics mode.
The video speaks for itself – basically a 2:1 performance advantage for the V7900 overall. Where the difference is really apparent is with the complex large models. That is in part GeometryBoost in action.
The Quadro does a good job of keeping up until the final test of an extremely tessellated model, where the Quadro really lags.
Now, there are many many questions about these benchmarks and I wish I had a FirePro to repeat them with (*hint hint*, anyone from AMD reading?) Issues like Screen Resolution and possible configuration options in CATIA itself could be impacting the results. Also, I’ld like to see a higher-end Quadro put through the test (Like the Quadro 5000), but does show that GeometryBoost is a huge benefit to the FirePro line.
The latest issue of Scientific Computing World has a nice 3-page article on Scientific Visualization, based on some classes and tutorials at recent events. They start off with a typical SciVis pipeline (Kudos to them for actually including “postprocess” after Render, so many groups stop at Render), and discuss several commercial and freely available package ranging from IDL to VTK.
If you’re already a SciVis guru then you probably won’t get much from it, but it’s a great article for scientists or newcomers to see what’s available.
OnLive is really scoring big at E3 this week, demonstrating their wares to show off some truly impressive gaming. One demonstration in particular really shows of what could be the future of gaming: Accessing “the cloud” for massive resources to view on your iPad.
OnLive even has a bluetooth controller they’ll make available, which should bring a more console-like experience for iPad users instead of having to use the touchscreen. Imagine pairing this with up with your HDTV via HDMI using the bluetooth controller, and you begin get a real sense of how truly awesome this could be.
Tiago’s latest contribution over at InspiredMag is now online, pulling together a nice list of infographics for World Environment Day.
June is traditionally a month dedicated to the Envionment. The 5th is the World Environment Day, and all over the world a number of initiatives occur, reminding us how dependant we are of Nature,and how much can we do, both as individuals and as a collective force.
Today we bring several infographic videos, from the many available on Visual Loop, that have in common the focus on the main environmental issues affecting the world. Hope they serve both as an alert and as an inspiration!
Continuing our series about the Environment, today we’ll be focusing on transportation, starting with Well Home‘s energy efficiency of movement and with the state of telecommuting in the U.S, provided by The Energy Collective. Crips Green brings in the Light Rail transportation for dummies infographic, and to close, a couple of visual representations of the Electric Cars, from Coda Automative and Green Liter.
Earlier today (2:41AM EDT), the sun kicked up a massive solar flare, and luckily NASA’s Solar Dynamics Observatory caught the whole thing on film.
NASA’s Solar Dynamics Observatory spacecraft caught high-definition video of the flare in different wavelengths. The event registered as a Class M-2 solar flare, which is a medium-class sun storm that should not pose a danger to satellites or infrastructure on Earth.
The images are beautiful, but tomorrow this could wreak a little havoc when the resulting magnetic wave hits earth.
