Octree - Wikipedia
网页An octree is a tree data structure in which each internal node has exactly eight children. Octrees are most often used to partition a three-dimensional space by recursively subdividing it into eight octants.

网页2023年2月2日 · Octree is a tree data structure in which each internal node can have at most 8 children. Like Binary tree which divides the space into two segments, Octree divides the space into at most eight-part which is called as octanes. It is used to store the 3-D point which takes a large amount of space.

网页2014年1月20日 · So, as you've read, an octree is a special type of subdividing tree commonly used for objects in 3D space (or anything with 3 dimensions). Our enclosing region is going to be a three dimensional rectangle (commonly a cube).
网页OCTREE STRUCTURE Each node boundary can be described by a center point and a span. For convenience we also define three axis aligned dividing planes (YZ, XZ, XY). We’ll use these to quickly determine intersections between our ray and the nearest child volume. Node description

Quadtree and Octree - SpringerLink
网页2017年1月1日 · An octree is a spatial decomposition where the root of the tree is recursively divided by two in each coordinate direction until each cell holds at maximum a specified number of objects. The octree groups its objects hierarchically, which avoids the representation of empty portions of the space.
