A volumetric display device is a display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via ...
In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired by a CT , MRI , or MicroCT scanner .
Volumetric capture or volumetric video is a technique that captures a three-dimensional space, such as a location or performance. [1] This type of volumography acquires data that can be viewed on flat screens as well as using 3D displays and VR headset .
Filming of the tornado sequence from Steven Spielberg's The Fabelmans (2022) on the StageCraft Volume at Manhattan Beach Studios (top) and the finished scene (below).. While shooting the film Rogue One (2016), cinematographer Greig Fraser encountered multiple issues which inspired the idea to use large LED screens as a component of the set.
Instead, rendering systems infer the position of a voxel based upon its position relative to other voxels (i.e., its position in the data structure that makes up a single volumetric image). Some volumetric displays use voxels to describe their resolution. For example, a cubic volumetric display might be able to show 512×512×512 (or about 134 ...
A volumetric haptic display (VHD) is similar to a (visual) volumetric display, but informs touch instead of vision. A VHD projects a touch-based representation of a surface onto a 3D volumetric space. Users can feel the projected surface(s), usually with their hands. The display is otherwise not detectable, and offers no visual feedback.

Each sheet in the volumetric stack is printed with a color slice of a digital 3D model, placed in a vacuum chamber, and then injected with a fluid matching the index of refraction of the sheet material. [3] Volumetric printing has been called "Hologram 2.0" by a company marketing the technology.
