Spatial Partitioning Representations

 it is used to describe interior properties, by partitioning the spatial region, containing an object into a set of small, non-overlapping, contiguous solids. e.g. 3D object as Octree representation. 

a solid is decomposed into a collection of adjoining, nonintersecting solids using spatial partitioning representations,. A quadtree is a representation format used to encode images. The fundamental idea behind the quadtree is that any image can be split into four quadrants. Each quadrant may again be split into four sub-quadrants, etc. In the quadtree, a parent node represents the image, while four child nodes, in a predetermined order, represent the four quadrants.

The following are different spatial partitioning techniques:

1.Cell Decomposition

2.Spatial Occupancy Enumeration

3.Quadtrees and Octrees

4.Binary space partitioning Trees
