Intel expects the rise of 'the 3D web' to transform the way people use the internet, with virtual worlds such as Second Life being deployed in the medicine and wider business sectors.
Chief Technology Officer Justin Rattner said in his last-day keynote address at the IDF (Intel Developer Forum) in San Francisco that this trend would provide a boost to his company by placing high demands on computer processors.
"This may be the killer app of killer apps," Rattner told reporters after they keynote. "As people demand a more immersive, more realistic experience, they're just going to push the computing demands to unprecedented levels."
The pressure on central and graphics processors has already soared as internet use has expanded from traditional web pages to applications such as Google Maps, Google Earth, multiplayer online role-playing games and Second Life. Going from surfing the traditional web to traversing Second Life can increase CPU load by three times and graphics processing load by 20 times, Rattner said.
Servers need to work harder, too. A server that could support 2,500 concurrent players of the online game World of Warcraft, for example, could only support 160 Second Life participants, Rattner said.
Rattner's keynote was colourful and entertaining for an IDF presentation, full of animation and simulations, but he outlined how much farther this richer experience has to go. For example, the kind of realism people expect from movies requires shadows and reflections that move with objects in a scene, he said. Daniel Pohl, a research scientist at Intel, demonstrated high-definition environments in the game Quake that included those elements and others. They demanded nearly all the processing power of a server with dual quad-core Intel x5365 chips.
In medicine, doctors are aiming to allow surgery on virtual patients. With current technology they can simulate cutting a rectangular patch of skin and opening it up in real time, but it would take far more processing power to do the same with a curved piece of skin or a cleft palate, according to Joseph Teran, a UCLA (University of California, Los Angeles) assistant professor who participated in the keynote.
Other challenges for making the 3D web a reality include user interface and standardisation, Rattner said. Tasks that take computer artists hours, such as creating shadows or reflections, need to be automated so that the average person can create user-generated content in an elaborate online world. Humans also need a better interface with the online world, Rattner said. He demonstrated the SpaceNavigator from Logitech's 3DConnexion division, which can be pushed and pulled to interact with a virtual environment, and Novint Technologies' Falcon, a three-dimensional game controller with force feedback. In addition, the mostly proprietary world of virtual worlds needs to embrace common standards so that, for example, avatars from one world can enter another, Rattner said.
