In computer science, a k-d tree (short for k-dimensional tree) is a space-partitioning data structure for organizing points in a k-dimensional space. K-dimensional is that which concerns exactly k orthogonal axes or a space of any number of dimensions. [1] k-d trees are a useful data structure for several applications, such as:
The bottom level of the octree consists of leaf nodes that accrue color data not represented in the tree; these nodes initially contain single bits. If much more than the desired number of palette colors are entered into the octree, its size can be continually reduced by seeking out a bottom-level node and averaging its bit data up into a leaf ...
Buddleja globosa, also known as the orange-ball-tree, [1] orange ball buddleja, and matico, is a species of flowering plant endemic to Chile and Argentina, where it grows in dry and moist forest, from sea level to 2,000 m. [2] The species was first described and named by Hope in 1782. [3]
There's a tree in your backyard that produces spiked round balls, and you have no idea what it is. We can help you identify it, and explain the purpose of those odd seed pods it drops.
Tabernaemontana donnell-smithii is an evergreen tree in the dogbane family Apocynaceae commonly known as the horse balls tree. In Spanish, it is huevos de caballo, cojones de burro, cojón de mico, or cojotón. The name, huevos de caballo, comes from the oval shape of the tree's hanging fruit. [2] It is native to Mexico and Central America.

In computer science, a K-D-B-tree (k-dimensional B-tree) is a tree data structure for subdividing a k-dimensional search space. The aim of the K-D-B-tree is to provide the search efficiency of a balanced k-d tree , while providing the block-oriented storage of a B-tree for optimizing external memory accesses.
There are also several octree types that differ by their leaf node's properties. Each leaf node can hold a single point or a list of point indices, or it does not store any point information. The library can be also used for detection of spatial changes between multiple unorganized point clouds by recursive comparison of octet tree structures.
