The Spirit Portal uses live 3D depth tracking cameras, projection mapping, and a holographic dry mist screen to create a free-floating image of patrons’ auras, mirroring their movements and actions in the real world.
3D Motion Capture
3D depth cameras are used to create a digital 3D version of each patron in real-time and track them as they approach and pass through the portal. After digital manipulation of the captured data, the resulting images are projected and mapped onto a holographic dry mist screen.
The holographic dry mist screen works on the principle of refraction, similar to a rainbow. Images are projected onto an ultra-fine water mist which refracts the light toward individual patrons, creating the illusion of a hologram. The screen utilizes a high-pressure misting system and specialized nozzles to create water droplets nearly 100 times smaller than the width of a human hair. This causes the droplets to evaporate just before touching the patron’s skin, allowing them to remain completely dry while also producing a “cooling” sensation.
