Enthusiast launched Doom on a volumetric voxel display

Weta Workshop graphics engineer James Brown has created a device in the shape of a ball that rotates and displays a flickering 3D image. The enthusiast was able to run Doom on it.

Brown used the Voxel version of Doom. In it, each point of the game object is assigned a position in 3D space, just like points on a volumetric display. The display itself is not 3D. “It’s like a holographic fan, but instead of rotating a 1D strip to produce a 2D image, it rotates a 2D panel to produce a 3D image,” the engineer explained.
