Spatial-Occupancy Enumeration:

This is a special case of cell-decomposition in which the solid is decomposed in identical cells arranged in a fixed regular grid. These cells are frequently called voxels (volume elements), in analogy to pixels. The most common cell type is the cube, and the representation of space like a regular array of cubes is called as cuberile. While representing an object by using spatial-occupancy enumeration, only we control the presence or absence of a single cell at each of the position in the grid. To represent an object, we require only deciding which cells are occupied cells. It is simple to find out whether a cell is inside or outside of the solid and finding whether two objects are adjacent is simple as well. It is frequently utilized in biomedical applications to represent volumetric data attained from source such as computerized axial tomography (CAT) scans.
