Volumetric display
A volumetric display is a display device that forms a visual representation of an object in three physical dimensions by making the light coming from it appear to exist physically in a volume of space. Volumetric displays can generate perspective correct content.
They also support multiple viewpoints.
Two companies that have made volumetric displays are Voxon and Actuality.
A basic example is an LED cube.
A volumetric display does not have to display data stored in a volumetric format. Volumetric formats take up much space, specifically dense uncompressed volumetric formats. Instead, a volumetric display can display polygonal graphics.
Types[edit]
Volumetric displays often use the persistence of vision effect, and project an image onto a moving rotating or otherwise oscillating target.
A volumetric display may be capable of reconstructing scenes with viewer-position-dependent effects if it has voxels with non-isotropic radiation profiles.
List of volumetric displays[edit]
This is a list of volumetric displays:
- Barry Blundell's volumetric cathode ray tube
- Voxon VX1
- Voxon VX2
- Voxiebox
- Actuality Perspecta
- Depthcube
- USC Volumetric Display[1]
- Vortex
- VVD
Near-eye volumetric display[edit]
A volumetric display can be shrunk down and built into a near-eye optical engine, with lensing to spread the focal range out a meter or more.
