A voxel is a three-dimensional counterpart to a pixel.It represents a value on a regular grid in a three-dimensional space.Voxels are frequently used in the visualization and analysis of medical and scientific data (e.g. geographic information systems (GIS)). [1]

Voronoi polygons for a group of texels. In computer graphics, a texel, texture element, or texture pixel is the fundamental unit of a texture map. [1] Textures are represented by arrays of texels representing the texture space, just as other images are represented by arrays of pixels.
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.
UV-light and green-light patterns are aimed at the dye solution, which initiates photoactivation and thus creates the "on" voxel. The device is capable of displaying a minimal voxel size of 0.68 mm 3, with 200 μm resolution, and good stability over hundreds of on–off cycles.
This is the scale which MOROP has defined for O scale, because it is half the size of the 1:22.5 Scale G-gauge model railways made by German manufacturers. [citation needed] 1:43.5: 7.02 mm: Model railways (0) Exact O scale of 7 mm = 1 foot. 1:43: 7.088 mm: Die-cast cars: Still the most popular scale for die-cast cars worldwide, metric or ...
The geometry in solid modeling is fully described in 3‑D space; objects can be viewed from any angle. Solid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes .
Voxel Grid. In this filtering technique input space is sampled using a grid of 3D voxels to reduce the number of points. [40] For each voxel, a centroid is chosen as the representative of all points. There are two approaches, the selection of the voxel centroid or select the centroid of the points lying within the voxel.
