To display a 3D hologram, three things are usually required:

1. A hologram projector (also known as a holography pyramid or holography display), which makes the holographic 3D projection possible.
2. A 3D hologram that is projected straight into the room and displays the content (in our example, the whiskey that virtually flows into the glass).
3. A real object or product that is displayed by the hologram (in our example the glass).

Hologram projectors are available in various sizes, which are optimally adapted to suit various purposes and products. 3D holograms offer a wide variety of applications.
