VirtualGeography – the newsletter
|G’Day… and Welcome to VirtualGeography
|Welcome to another free VirtualGeography from VizMAP Pty Ltd.
In the immortal words of Al Pacino in Scent of a Woman, "Ooh Aah".
The Federal Government’s "dark side" has been keeping us busy during winter here at VizMAP. Them, and the Queensland Government. Not to mention the Queensland Spatial Conference on the Gold Coast 17-19th July (http://www.qsc2008.com.au/). VizMAP hosted a workshop, "Behind the Scenes" (what a great title!) and presented a paper, "Case Studies in 3D Visualisation". A good time was had by all, particularly at the Casablanca themed conference dinner.

If you didn’t already know, VirtualGeography is a collection of interesting snippets from all over the shop, dealing with industry issues concerning the computer based visualisation of geography and a few other associated (or otherwise) interesting bits and pieces. You are receiving this either because you subscribed to VirtualGeography or you have had recent dealings with VizMAP Pty Ltd. If you do not wish to receive further installments of VirtualGeography, just click on the unsubscribe link at the bottom of this e-mail.
A new VirtualGeography is pushed out every now and then when we’ve collated enough interesting bits and pieces, which shouldn’t be too big a drain on your mailbox if you’re not already subscribed (of course it won’t be a drain on your mailbox if you ARE subscribed, either ). The regularity of the distribution may vary depending on what else is going on at VizMAP at the time. If you know of anyone who might like to get VirtualGeography, feel free to forward this to them and ask them to subscribe. By the way, subscription and unsubscription details are at the bottom (click here).
So, g’day to all you enthusiasts requiring to visualise and simulate both urban and rural geographic information (GIS), cartography, photogrammetry, remote sensing, digital elevation modelling (DEM) and general mapping.
By the spelling of "Visualisation" you may have already guessed that we’re not US based – that’s a good thing, or at least not a bad thing. This comes to you from Mooloolaba on the Sunshine Coast of Queensland, Australia, where it’s beautiful one day and perfect the next. As a postscript to that, you can have a look at the Mooloolaba beach, now, 800m from where I sit as I write this, here.
The link between visualisation and mapping may seem a little esoteric if this is your first encounter with this sort of stuff, but let me tell you, the bond is significant… but enough of that: on with the show… I hope you like it. Any feedback you might have is highly appreciated. E-mail me here to make your comments.

|The Industry’s Two Cents Worth…
|TerraSim Releases TerraTools Version 3.5
|Pittsburgh, PA – TerraSim has released Version 3.5 of TerraTools® Core, its 3D geospatial database construction product supporting correlated visual and constructive simulation systems. TerraTools supports up to eight parallel processing threads on a single multi-core Windows workstation, making it the most cost effective COTS database construction toolkit. TerraTools Core contains over 50 major feature enhancements and represents a significant increase in speed, usability, and functionality. We have added new TerraTools nodes to support enhanced building interior generation and other Urban Details™ construction as an integral part of basic TerraTools geospatial data processing. This includes new middle-eastern regional models and textures added to our extensive library of over 500 unique models and 1200 appearance textures. TerraTools 3.5 is being shipped to all TerraSim customers as a no cost upgrade under their annual maintenance and support agreement.
TerraTools 3.5 supports separately priced export options as plug-ins to TerraTools Core, including OneSAF, JCATS, CTDB, MÄK VR-Forces and OpenFlight, allowing customers to configure systems at cost-effective price points.
OneSAF export supports OOS version 2.0 as well as versions 1.1 and 1.5 for international customers and compatibility with ongoing exercises. OneSAF Ultra High Resolution Buildings (UHRB) produced by ARA’s U2MG building generator or imported from the TerraTools UHRB model library are fully supported including automated placement and building diagnostics.
In addition to producing the most polygon efficient generation of OneSAF terrain databases (OTF), TerraTools’ flexible scripting tracks all versions of the OneSAF Environmental Data Model (EDM). Advanced user diagnostic support and multi-cell export support results in a highly reliable and robust export capability for large area database construction.
For users with legacy OneSAF Testbed (OTB) requirements, TerraTools CTDB export continues to support GCS database construction and multi-cell GCS export as well as modeling of complex building (MES) structures.
JCATS users can choose between integrated TIN or vector features on gridded terrain representations in JCATS format 7.1.5 or recently released JCATS format 8.0. Enhancements for our OpenFlight and MetaFlight export support multi-textures, lightpoints, and large area database format. Our plug-in for BAE Systems SOCETSET GXP has been updated to support version 5.2.

|Hardcore Stuff (hardware bits)…
|Beyond Graphics – The Present and Future of GP-GPU
|It wasn’t so long ago that 3D graphics cards were only expected to deliver higher frames-per-second in your favorite 3D games. Sure, the graphics companies fought over some image quality issues like the internal color processing precision and the quality of anti-aliasing or anisotropic filtering, but even that was targeted at game performance and quality. Of course, there have been graphics cards for years now designed for the professional 3D market—CAD/CAM, industrial design, folks like that. Still, it’s all 3D rendering of some form or another.
The first hint of graphics cards doing something "more than 3D" was with the introduction of video acceleration. It started out simple, with partial decoding of MPEG video, moving gradually into full acceleration of the MPEG2 used in DVDs, and today is quite robust. Modern graphics cards accelerate much of the decoding steps required for sophisticated codecs like VC-1 and H.264 (both used in Blu-ray movies), along with de-interlacing, noise reduction, dynamic contrast control, and more. Much of this work is done in dedicated video hardware on the GPU.
The release of DirectX 10, with unified vertex/pixel/geometry shaders and stream-out functions brought with it a class of hardware that is more flexible, and more easily able to handle other computing tasks. Research into using the powerful parallel processing of GPUs has been going on for years. They call it "GP-GPU," for general-purpose computing on a GPU, and it’s about ready for the mainstream.

|Street View Arrives
||from Asian Survey & Mapping
|Google released Street View imagery of Japan and Australia on 5 August. A user can select a point on a road, and then view the scene in any direction. The imagery was derived from a 360 degree camera system.
The coverage of Japan is limited to the Tokyo-Yokahama-Chiba metropolis and Osaka on Honshu, and to Sendai, Sapporo and Hakodate on Hokkaido.
Coverage in Australia is the most complete of any country. It covers all the cities and much of the sparsely populated interior. Street View was introduced into five US cities in May. It is also available along the Tour de France route.
Google has not announced any plans for coverage in other countries in the region. However, it is facing legal challenges in Canada and the UK, because of privacy concerns, and may raise issues among security authorities in other countries.
Go to maps.google.com and press the Street View tag.

|VizMAP recently created a visualisation of one of, if not THE best walking trek on the planet – the Annapurna Circuit in Nepal. This from WikiTravel:
17 to 21 days long, this trek takes you through distinct sceneries of rivers, flora, fauna and above all – mountains. The trek goes counter-clockwise and reaches its summit in Thorung La (pass) at the height of 5416m, or more than 16,000 feet. The route goes past the following mountains: Manaslu (an 8,000-plus meter peak), Langtang Himal, Annapurna II and IV, Annapurna III and Gangapurna, and, of course, Annapurna I and Dhaulagiri — passing through the world’s deepest gorge in between those two 8,000-plus meter peaks. Poon Hill, at the end of the trek, affords views of those two mountains, as well as South Annapurna and Macchupucchre, the "Fishtail Mountain." The trek also goes through Buddhist villages and Hindu holy sites, most notably the village of Muktinath, a holy site for both Buddhists and Hindus.

|Computer-generated Images: Hollywood Hair Will Be Captured At Last
||from Science Daily
|ScienceDaily (Aug. 13, 2008) — University of California, San Diego today announced a new method for accurately capturing the shape and appearance of a person’s hairstyle. The results closely match the real hairstyles and can be used for animation.
Imagine avatars of your favorite actors wandering through 3D virtual worlds with hair that looks almost exactly like it does in real life. This level of realism for animated hairstyles is one step closer to the silver screen, thanks to new research being presented at SIGGRAPH, one of the most competitive computer graphics conferences in the world. The breakthrough is a collaboration between researchers at UC San Diego, Adobe Systems Incorporated (Nasdaq: ADBE) and the Massachusetts Institute of Technology.
The computer graphics researchers captured the shape and appearance of hairstyles of real people using multiple cameras, light sources and projectors. The computer scientists then created algorithms to “fill in the blanks” and generate photo-realistic images of the hairstyles from new angles and new lighting situations.
Adobe researcher and SIGGRAPH paper author Sylvain Paris explained that replicating hairstyles for every possible angle and then getting individual strands of hair to realistically shine in the sun and blow in the wind would be extremely difficult and time consuming for digital artists to do manually.
“We want to give movie and video game makers the tools necessary to animate actors and have their hair look and behave as it would in the real world,” said UC San Diego computer science professor Matthias Zwicker, also a SIGGRAPH paper author.
