Hollywood's 3D Scanning and Military Reverse Engineering

By Dayna Fields

Reverse engineering has done wonders for many industries- everything from food safety to the military. Likewise, 3D scanning has revolutionized the creative process for Hollywood and filmmakers all over the world.

One would agree with the amazing strides that have been taken, thanks to the help of these two amazing techniques and technologies.

A Hollywood filmmaker may want to scan in a plastered version of someone's face, which would lend the tools necessary to create a fictional character. A very high powered (and expensive) laser beam shoot over an object and converts all the data to the computer program, where the image will appear.

How the method works is with a very high powered (and expensive) laser beam, which shoots over an object as many times that the artist or engineer believes is necessary. For example, in Hollywood animation, an artist may want to scan in a plastered version of someone's face that he/she can stretch and sculpt into a fictional animated creation.

After the scan is completed, an immense amount of data is transferred to the computer. Incredible detail allows for incredible and organic realism, which every artist yearns for. Plus, the image offers 360 degrees of viewing. In the end, artists can stretch, sculpt, paint or mold whatever they want in order to create the creature of their desire with relative ease.

Reverse engineering is something that every science geek can relate to because it is really nothing more than taking things apart to see how they work and then trying to build your own. The trick is that you can't use any materials or methods from the original work.

During the Cold War, for example, the Soviets saw three American B-29 bombers that were forced to land in the USSR. Not having anything similar to the B-29, they confiscated an example, took it apart and within a few years they had an almost exact replica- with a Soviet spin on it, of course. They dubbed the weapon the Tu-4.

In conclusion, both processes and technologies produced incredible amounts of data and insights, as well as shockingly impressive and accurate results.
