Bounding Volume Hierarchy (BVH) is a popular ray tracing acceleration technique that uses a tree-based “acceleration structure” that contains multiple hierarchically-arranged bounding boxes (bounding volumes) that encompass or surround different amounts of scene geometry or primitives. Testing each ray against every primitive intersection in the scene is inefficient and …

Bounding Volumes. A bounding volume is for example an Axis-Aligned Bounding-Box (AABB), a generaal Bounding-Box not aligned with the major axes or a Bounding-Sphere. They differ in. how much memory they take (e.g. a sphere takes only 4 floats, AABB 6 floats) how good they enclose the object's geometry. how fast are the related computations ...
A Survey on Bounding Volume Hierarchies for Ray Tracing

Thus, scene primitives are commonly arranged in spatial data structures to accelerate the search. In the last two decades, the bounding volume hierarchy (BVH) has become the de facto standard acceleration data structure for ray tracing-based rendering algorithms in offline and recently also in real-time applications.

In the last two decades, the bounding volume hierarchy (BVH) has become the de facto standard acceleration data structure for ray tracing-based rendering algorithms in offline and recently also in real-time applications. In this report, we review the basic principles of bounding volume hierarchies as well as advanced state of the art methods with

Ray tracing was used for rendering at least as early as the classic work by Appel [1968], but was introduced in its modern form by Whitted [1980]. To speed up intersection, hand-constructed bound-ing volume hierarchies (BVHs) [Clark 1976] were the first spa-tial efficiency structure used for ray tracing [Rubin and Whitted 1980; Whitted 1980].

Ray Tracing acceleration structure to both build and perform the steps necessary to efficiently render dynamic scenes. Bounding Volume Hierarchy (BVH) is a commonly used acceleration structure, which aides in rendering complex scenes in 3D space using Ray Tracing by breaking the scene of triangles into a simple hierarchical structure.
How to sort and compare in a Bounding Volume Hierarchy
https://stackoverflow.com/questions/15013523/how-to-sort-and-compare-in-a-bounding-volume-hierarchy
The easiest to think about is to use the centroid of the bounding box. You could also sort by the min coordinate and separately by the max coordinate. You can sort by each axis as a preprocess. Then each iteration is a partitioning that involves choosing which axis to split on and where to split, and storing the start/end points in that axis's ...
