Dean Takahashi sent me an e-mail pointing to a piece he wrote on VentureBeat describing statements Wednesday by Intel's Chief Technical Officer Justin Rattner targeted at NVIDIA. CNET's own Brooke Crothers covered the same story and provides additional background here.

The technology at issue relates to 3D graphics for PCs. All current PC graphics chips use what's called polygon-order rendering. All of the polygons that make up the objects to be displayed are processed one at a time. The graphics chip figures out where each polygon should appear on the screen and how much of it will be visible or obstructed by other polygons.

Ray tracing achieves similar results by working through each pixel on the screen, firing off a "ray" (like a backward ray of light) that bounces off the polygons until it reaches a light source in the scene. Ray tracing produces natural lighting effects but takes a lot more work.

(That's the short version, anyway. For more details, you could dig up a copy of my 1997 book Beyond Conventional 3D. Alas, the book is long since out of print.)

Ray tracing is easily implemented in software on a general-purpose CPU, and indeed, most of the computer graphics you see in movies and TV commercials are generated this way, using rooms full of PCs or blade-server systems.

Naturally, Intel loves ray tracing, and there are people at Intel working to… Read more

Press Windows + R, then type "calc" and enter. That's how you can quickly bring up the calculator application on your Windows computer. This is also the reason many of us do not need a physical calculator around as there's always a PC nearby. But if you are going to have a calculator, here's one worth getting--the 10 Key Calculator created by U.K. designer Sam Hecht, as seen on Boing Boing.

It doesn't really have only 10 keys, but this calculator looks very much like your computer's numeric keypad. You no longer have … Read more

The legendary Museum of Modern Art in midtown Manhattan just got a bit more...modernized.

MoMA announced Monday that it has installed a museum-wide Wi-Fi network so that visitors can access a mobile Web site on handheld devices with HTML browsers, which basically means Apple's iPhone and iPod Touch. They can then load up audio tours and commentary; content is available in eight languages as well as in specialized versions for children, teenagers, and the visually impaired.

It's not clear whether the museum Wi-Fi will also let visitors access the Web as a whole, or just the internal … Read more

Update: This story has been corrected to reflect that the date of the public opening of the exhibit is May 10.

MOUNTAIN VIEW, Calif.--"Excuse me, Richard, we have a very large parcel."

With those words, spoken by John Shulver of London's Science Museum, a day of supreme geekery unfolded at the Computer History Museum here.

To be precise, the package in question was the delivery and installation of a difference engine, a brand new model of a 19th-century-era machine designed--but never actually built--by Charles Babbage. It was designed to be a mechanical calculator which can … Read more

On Thursday afternoon I was back at the Computer History Museum. The Honda Research Institute was hosting its tenth Technical Horizon Symposium and announcing this year's Honda Initiation Grant awards.

The grants are part of the Institute's efforts to stimulate collaborate research between Honda and the academic community. Since 1997, Honda says it has awarded 75 grants totalling "several million dollars" to universities in the US. This year, Honda received 300 proposals; it chose seven. This year's awards (listed here along with those of past years) cover research in safety, efficiency, emissions control, and user … Read more

I had a great time over the weekend at the 10th Vintage Computer Festival, which took place in the Computer History Museum in Mountain View, Calif.

In addition to the exhibits of vintage computers--including the largest collection of Radio Shack Pocket Computers I've ever seen--and the marketplace, where I managed to avoid buying any slide rules, Vectrix video games, or Cray supercomputer circuit boards--there were several notable presentations.

On Saturday, Tim McNerney spoke about his work to reimplement the Intel 4004 microprocessor, which led to a 130x-scale working model of the chip composed of individual transistors on a large … Read more

I've been to a lot of computer conferences over the last 30 years-- my first was the mainframe-oriented National Computer Conference in 1979, and I've probably been to 250 more since then-- but one of my favorites is also the smallest: the Vintage Computer Festival, hosted by Sellam Ismail.

Over the years at these conferences (a collection of my badges as of 1998 or so is shown here), and in my own life, I've seen and used an awful lot of computer hardware.

I'm surprised that some kinds of systems that were very popular in the … Read more

If you visit the National Museum of Singapore, you can get your very own Chinese Companion. Sorry, this one won't make moo eyes at you--instead, it speaks in an electronic voice and is programmed to give visitors access to videos and reading materials on the relevant artifacts and topics in the museum. The National Museum of Singapore claims it is the first and only museum in Southeast Asia, for now, to incorporate an interactive handheld companion to complement its exhibits.

The handheld personal guide, which was developed by Canadian firm GSM, is part of the Companion project which involved … Read more

Just when we were about to begin a self-imposed moratorium on highest-end turntables, along comes another one that we simply can't resist.

The luxury edition of the "AAS-Gabriel" from Switzerland's Da Vinci Audio Labs looks more like fine porcelain than a piece of entertainment equipment, accented with 24-karat gold plate. As for its technical performance, Technabob offers this explanation: "The turntable is designed to produce absolutely zero noise or vibration, and goes so far as to completely isolate the pick-up arm from the rest of the player."

Makes sense to us, though that's … Read more
