Creating The Amazing 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.

Slowly 3-D is also coming to general home entertainment systems. The standard technology works with shutter glasses you have to wear, to make a 3-D effect visible. There are also already a few trials from some companies to make the 3-dimensional effects possible without glasses. The problem is that this plus in comfort is a minus in quality and viewing angle. As the development continues, the next big thing is already with us here, this is the holographic 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.

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.

In addition to the transparent film surface, there is a flat surface behind the transparent surface to reflect the light that goes through the surface. This gives the 3D images an appearance of a floating object between space. This is the source if the stunning visual display normally associated with the hologram display.

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.

You can Google the two projects I wrote about and you'll probably find a few videos which show you of what I am talking. You'll not see the holographic effect, of course, because it's a normal video.
