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 ...
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.
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).
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.
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 .
A volumetric print can be thought of as a reconstructed light field based on the scattering of light by distributed pigments in volume. Any three-dimensional scene can be volumetrically printed, although biological specimens and volumetrically X-rayed objects (i.e., CT scans) are thought to be particularly well suited to this type of imaging.
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 ...
- Volume rendering by high and low threshold for radiodensity. In scientific visualization , a maximum intensity projection ( MIP ) is a method for 3D data that projects in the visualization plane the voxels with maximum intensity that fall in the way of parallel rays traced from the viewpoint to the plane of projection.
