What It Take To Create A Mind-Blowing Hologram Illusion

By Melissa Cole


The popularity of the 3D TVs and projection is gaining popularity by the day, in fact, the concept of 3D movies is no longer new. Many of us have experienced this amazing technology. Unknown to many, the technology is quickly evolving, we are moving from 3D displays to the next big thing. This is the hologram illusion.

The animators deploy the principles of Pepper's Ghost technology, a technology that gives them the ability to protect a holographic visual and ghost-like images. However, the new animators are able to deviate from the original Pepper's Ghost technology by using the display to create a depth illusion.

In order to create a depth illusion, the image has to be projected through a transparent film surface and then into a flat surface behind it. While the film surface reflects some of the light, the rest goes through and is reflected by the flat surface behind the transparent film surface. Consequently, the result is an illusion of the 3D image appearing as a floating object between the spaces. This stunning visual display is what we call hologram.

The transparent surface may be a glass or a transparent film. Either way, the film used as the surface is specifically aligned to be able to give the desired illusion. A reflection of an item, object or a person gets displayed on the transparent surface with the help of a special lighting effect.

In order to create the 3D holographic images, there are equipment that has to be put together and coordinated by experts. The most common equipment you are likely to find in the arrangement include the HD projectors, the 3D modelling software, the media players, and the transparent film surface treated with specific chemicals.

Right now a team of the University of Arizona managed to take holographic pictures of a moving object and could update the picture every two seconds. That's still far away from 24 pictures per second, which makes a floating movie.

When the Microsoft Kinect is used to capture the holographic images, the result can be amazing. That already sounds good, but the quality is far from being OK. Actually, the quality doesn't matter right now. Currently, the main objective revolves around creating a technology that captures and displays the holograms in real time. This can later on be followed by an improvement in quality.

Today, the companies are adopting this technology as the new age in advertising. The holographic projection specialists are now on high demand for these types of advertising and other forms of 3D displays. The content is the 3D modelling which means that only the imagination and budget is the only possible limitation to the storyboard displays. By creating the objects in 3D, an endless series of wind blowing animations can be obtained. At the heart of it all is the 3D modelling software.
