A European Union program has helped several European partners to develop the Virtual Planet (or V-Planet) software, which will enable its users to browse and interact in three dimensions with any part of our planet, according to IST Results. "Using Vplanet Explorer, anyone can set off on a journey to discover new regions in 3D, rather than staring at a flat map and trying to picture its scenery," says Eric Martin, coordinator of the IST project. The software can also be used for technical simulations and has already been used by both Airbus and Boeing. It should be available this summer for about 10,000 euros (about $12K).

The project's software merges data from different sources into a single 3D database, using techniques such as filtering, correlation and specially developed 3D algorithms. The partners concentrated their work on surface areas and sub-metric resolution, taking advantage of improvements in pixel resolution in today's satellite data.
"The challenge is handling large volumes of geographic data on a standard computer," says Martin. By working on a PC with a standard graphics cards, it is possible to significantly reduce the cost of working with complex Geographic Information Systems (GIS). He adds: "Our project offers users a transition from GIS to 3D, especially as our software's open architecture enables interfacing with other software."

This one shows a "real-time inspection of a complex scene containing the St. Matthew 0.25mm dataset (373M triangles), the LLNL Richtmyer-Meshkov simulation isosurface (472M triangles), and full Boeing 777 CAD model (350M triangles). The image is approximated using 4M voxels and 595K triangles." It will be presented at SIGGRAPH 2005 in August.
This one shows a "real-time inspection of the full Boeing 777 CAD model (350M triangles). The image is approximated using 1M voxels and 3.4M triangles." It also will be presented at SIGGRAPH 2005 in August.
This one shows a "exploration of the whole planet Mars (2G triangles) reconstructed from Mars Orbiter Laser Altimeter 128 samples/degree data." This image, which has been published in August 2004, is the collective work of Paolo Cignoni, Fabio Ganovelli, Enrico Gobbetti, Fabio Marton, Federico Ponchio, and Roberto Scopigno.
As you can see, this software can be used for a large variety of applications. And, in addition to customers such as Airbus or Boeing, Vplanet Explorer was used on the inauguration day of the Viaduc de Millau in France, the world's highest bridge, for a public presentation, which combined a digital model of the terrain with data from the Spot 5 satellite and modeling of the bridge itself.
"Local people had resisted the bridge's construction, claming it would ruin the scenery," adds Martin. "Had they seen our presentation earlier, showing the bridge is not a visual disaster, they might have accepted the new edifice without hesitation."
For more information about this software, you can visit the V-Planet project page or this IST project fact sheet. The images above were extracted from these documents.
The complete project package, which includes separate modules for software installation or training, will go on sale this summer for a price of about 10,000 euros, which means it's not intended for personal use.

Famous quotes containing the words virtual, planet and/or explorer:
“Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
—Jean Baudrillard (b. 1929)
“It was not important that they survive.
What mattered was that they should bear
Some lineament or character,
Some affluence, if only half-perceived,
In the poverty of their words,
Of the planet of which they were part.”
—Wallace Stevens (1879–1955)
“Treading the soil of the moon, palpating its pebbles, tasting the panic and splendor of the event, feeling in the pit of one’s stomach the separation from terra ... these form the most romantic sensation an explorer has ever known ... this is the only thing I can say about the matter. The utilitarian results do not interest me.”
—Vladimir Nabokov (1899–1977)
