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.

Scanning is used for a wide variety of applications- everything from invention prototypes to artistic creations. A real-world object is scanned and then the data is converted to a three-dimensional digital object.

The scanning analyzes a real-world object for its data, measurements and properties and converts that into an on-screen experience in a three-dimensional, digitalized form. This process can be used for a range of different applications- anything from prototypes for inventions, machines or what have you, to artistic creations like sculptures, buildings or paintings.

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.

Reverse engineering also is something that is key when it comes to creating new products and improving on others. In a way that a high school science geek can certainly relate to, the method is simply taking this apart only to see how it works and creating one of your own. But you cannot use the same materials or inner workings of the original.

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 the end, both highly sophisticated processes are revolutionizing many fields of industry and creating a simple process that yields an incredible amount of data and shockingly accurate results.
