Recently, a "gameplay" recording of Duke Nukem 3D, published by Voxel Photonics, went viral on social media. The company is involved in creating real 3D volumetric displays that project physical 3D light images.
They demonstrated the capabilities of their technology using the classic shooter as an example:
Here's Duke Nukem 3D running in physical 3D space on a Voxel Photonics display. The game, published by 3D Realms and GT Interactive, ran on Ken Silverman's Build Engine.
The spectacle amazed many viewers. Players in the comments noted that Holoduke – a gadget from Duke Nukem 3D that projected an image of the main character and allowed players to deceive enemies – has now become a reality.
The unusual "gameplay" recording of Duke Nukem 3D can be viewed at the following link.
Voxel Photonics noted that, theoretically, other games running on the Build Engine could be launched. However, the display creators mentioned that "not all of them have mods for 3D assets," so in some cases, game elements would look like "2D billboards."
