Volumetric displays are one of several kinds of 3D displays. Other types are stereoscopes, view-sequential displays, [2] electro-holographic displays, [3] "two view" displays, [4] [5] and panoramagrams. Although first postulated in 1912, and a staple of science fiction, volumetric displays are not widely used in everyday life. There are ...
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 .
This is an example of a regular volumetric grid, with each volume element, or voxel represented by a single value that is obtained by sampling the immediate area surrounding the voxel. To render a 2D projection of the 3D data set, one first needs to define a camera in space relative to the volume.
Worms 4: Mayhem uses a voxel-based engine to simulate land deformation similar to the older 2D Worms games. Luanti (previously Minetest) is a moddable sandbox video game that uses voxels to store terrain data, but does not use voxel rendering techniques. Instead, it uses polygon rendering to display each voxel as a cubic "block"
I disagree. "Occlusion-capable volumetric displays" are not volumetric displays. They are better classified as "light field displays" instead. They display a series of "views" (just like other light field displays), rather than display a series of "slices" (like normal swept-volume volumetric displays).
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire ...
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.
The technique of volume ray casting can be derived directly from the rendering equation.It provides results of very high quality rendering. Volume ray casting is classified as an image-based volume rendering technique, as the computation emanates from the output image and not the input volume data, as is the case with object-based techniques.
