What It Take To Create A Mind-Blowing Hologram Illusion

By Melissa Cole


If you are a 3D animator, you are probably familiar with the names like the 3ds Max and the Autodesk Maya. These are among several 3D modeling software that are the tools used to create the stunning visual effects that have taken alleviated 3D visual effects to the next level. The images can be stunning on the wall and TV projection, but the new hologram illusion has taken it to a completely new world.

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.

Holographic TV, what is it? Most people don't really know what holograms actually are or what they're capable of. Almost everybody knows princess Leia of Star Wars who talks as a free-floating hologram to her buddies. Even if I have to disappoint you: That's not possible, at least not in an easy way we could think of today. The problem is that light always needs, whether a source or something that reflects it, to find a way to your eyes.

It works by hiding the reality and only revealing the reflection of the real object to the audience. This means that the audience will not get to see the real person or object, but only the reflection of the person. The reflection is partly captured by the transparent surface while part of it passes through the same wall. This gives it a ghost-like object floating on a transparent wall.

This means that the real person or the real object is not seen by the audience, instead, only the reflection is visible on the transparent surface. Being transparent, not all the light is reflected, part of the light pass through to the surface behind it. This gives a display of the image of an object floating in space. It is the ghost-like images that has made this technology that special.

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.

This is as a result of the image projection onto the transparent film and a flat surface behind the transparent surface. This phenomenon make the 3D images appear as though they are floating objects on space between the transparent film and the surface behind it hence the stunning visual display that is associated with the technology.

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.
