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:
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.
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 ...
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 .
Cerbera odollam is known by a number of vernacular names, depending on the region. These include othalam (ഒതളം) in the Malayalam language used in Kerala, India; kattu arali (காட்டரளி) in the adjacent state of Tamil Nadu; dabur (ডাবুর) in Bengali; famentana, kisopo, samanta or tangena in Madagascar; and pong-pong, buta-buta, bintaro or nyan in Southeast Asia.
The plant also produces a small seedpod that starts out green, but then turns brown when fully matured. The seedpods usually have a length of 4–7 cm, and are 6–8 mm wide. The leaves which are one of the plant's key traits are made up of 10–20 pairs of long thin leaves that go down a stem. They come in pairs of 3–12.
