It's 5 pages long, but has some interesting tidbits in terms of advancing graphics technology.

I'm so stoked to see this movie.
p.s.: Can someone translate this: bidirectional reflectance distribution function
into english please? hehe.

If the dojo fight in The Matrix was a kung fu sonata, the Burly Brawl is a symphony. Neo tears the sign from the ground and wields it as a kendo sword, vaulting pole, and battering ram. A woman walking by can't believe what she's seeing; suddenly her body is hijacked, she drops her grocery bag, and another Smith charges into the fray. Whole battalions of Smiths arrive, mount assaults, attack in waves, scatter, regroup, and head back for more. (At ESC, one massive pile-on was dubbed the "Did someone drop a quarter?" shot.) In the thick of it, Neo is dancing, chucking black-tied bodies skyward, pivoting around the signpost, and using shoulders as stepping-stones over the raging river of whup-ass.
Fans will wear out their remotes replaying the scene on DVD, but what they won't see, even riding the Pause button, is a transition that happens early on. When Neo and Agent Smith walk into the courtyard, they are the real Reeves and Weaving. But by the time the melee is in full effect, everyone and everything on the screen is computer-generated - including the perspective of the camera itself, steering at 2,000 miles per hour and screaming through arcs that would tear any physical camera apart.
The standard way of simulating the world in CG is to build it from the inside out, by assembling forms out of polygons and applying computer-simulated textures and lighting. The ESC team took a radically different path, loading as much of the real world as possible into the computer first, building from the outside in. This approach, known as image-based rendering, is transforming the effects industry.
Then Reeves and Weaving each sat down on a stage in front of five Sony HDW-900 video cameras. The massive datastreams from these cameras - one gigabyte a second - were treated like holy water; even the cameras' color-correction software was disabled to prevent any loss of data.
How deep did the rabbit hole go? A cast of each actor's head was sent to a company called Arius 3D, makers of ultrahigh-resolution scanners employed in 1999 to archive the works of Michelangelo. The Arius scanner is accurate down to 25 microns - the diameter of a mold spore. To get the clothing simulations just right, ESC sent swatches of Reeves' black cassock and Weaving's jacket to a company called Surface Optics, which builds devices to measure a property of light called the bidirectional reflectance distribution function. Surface Optics happened to have one machine on hand scheduled to ship to Lockheed Martin a month later, where it was to be assigned to its usual task: evaluating the reflectivity of paint on stealth bombers.
The ability to create photorealistic virtual human beings raises unsettling questions, especially in conjunction with the means to cut-and-paste them into any landscape. These questions troubled Gaeta himself so much that, a few years ago, he wrote a letter alerting President Clinton to the fact that such technology could be used for purposes of mass deception. (The letter was never answered.)
As it happens, one group deeply interested in the new breed of hyperrealistic CG is the military. Darpa is fast-tracking image-based rendering and lighting for use in immersive battle simulations. In 1999, the US Army launched the Institute for Creative Technologies at USC, where Paul Debevec - Borshukov's former mentor at Berkeley - is now the head of graphics R&D.
Gaeta recognizes the paradox. "You have these paranoid films about the Matrix depicting how people are put in a mental prison by misusing this technology, and you have the military constructing something like the actual Matrix. Or maybe our technology will become the actual Matrix, and we have inadvertently spilled the vial of green shit out onto the planet."
