Volumetric displays

Definition

Volumetric displays are three-dimensional visualization systems that allow users to view and interact with digital objects in a spatial manner, providing depth perception and perspective from multiple angles. These displays create a sense of volume and presence, unlike traditional 2D screens, by rendering images within a defined volume of space. This technology is essential for applications such as 3D imaging and holography, enabling more immersive and realistic experiences.
