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 use of octrees for 3D computer graphics was pioneered by Donald Meagher at Rensselaer Polytechnic Institute, described in a 1980 report "Octree Encoding: A New Technique for the Representation, Manipulation and Display of Arbitrary 3-D Objects by Computer", [1] for which he holds a 1995 patent (with a 1984 priority date) "High-speed image generation of complex solid objects using octree ...
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.
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]

The tree and the cotton-like fluff obtained from its seed pods are commonly known in English as kapok, a Malay-derived name which originally applied to Bombax ceiba, a native of tropical Asia. [3] In Spanish-speaking countries the tree is commonly known as " ceiba " and in French-speaking countries as fromager .
Gomphocarpus physocarpus, commonly known as hairy balls, balloonplant, balloon cotton-bush, bishop's balls, nailhead, or swan plant, [2] is a species of plant in the family Apocynaceae, related to the milkweeds. The plant is native to southeast Africa, but it has been widely naturalized as it is often used as an ornamental plant.
If K = 1, a relaxed K-d tree is a binary search tree. As in a K-d tree, a relaxed K-d tree of size n induces a partition of the domain D into n+1 regions, each corresponding to a leaf in the K-d tree. The bounding box (or bounds array) of a node {x,j} is the region of the space delimited by the leaf in which x falls when it is inserted into the ...
