Moon Landing HOAX Debunked, Using Gaming Technology, page 1

Nvidia's New GPU Sinks Moon Landing Hoax Using Virtual Light

Using its new top-shelf graphics processing unit, Nvidia tackles one of the most persistent conspiracy theories in American history: the veracity of the 1969 to 1972 Apollo moon landings[

The first manned missions to Earth's satellite began in 1969 with Apollo 11. Just a few years later, conspiracies sprouted up claiming that potentially each of the six lunar landing crews and every one of the nine Apollo astronauts who walked on the moon had in fact participated in an elaborate ruse. To the conspiracists, it may never have happened -- or didn't happen like NASA said it did -- and oh by the way, we duped the Russians into losing the space race.

Voxel global illumination, however, proves them wrong, says Nvidia. The technique, which the new GTX 970 and 980 can tap into, lets developers use dynamic lighting that will bounce, diffuse and reflect in real-time with unprecedented fidelity when new objects are added to a scene. That makes it the perfect rendering tool to tackle moon landing hoaxes that often use as evidence for their claims lighting discrepancies with NASA photography.

The result is a near-perfect replication of the 1969 Apollo 11 landing site. Nvidia tackled some of the most persistent claims used to support a moon landing hoax, starting with the notion that astronaut Buzz Aldrin couldn't have been illuminated when descending the ladder to the moon's surface if he was hidden from the sun by the spacecraft.

There you have it.
Pretty difficult to argue this one, now that it's been reproduced digitally with extreme accuracy.
