Ray Tracing with the BSP Tree
https://www.sci.utah.edu/publications/ize08/BSP_RT08.pdf
In ray tracing, we are notawareofasinglehigh-performanceraytracerthatusesarbitrarily oriented planes. Instead, ray tracers typically use kd-trees, which are a restricted type of BSP tree in which only axis-aligned splitting planes are allowed1. Kd-trees provide storage and computation advantages but do not conform as well to scene geometry.

There are two basic modules in a BSP tree intersection code. The first module builds the tree by recursively cutting the bounding box of all objects along a median spatial plane. The second module tracks a ray through the leaf nodes of the BSP tree checking for intersections. The BSP tree is built by InitBinTree ( ) and Subdivide ( ).
Ray Tracing with the BSP Tree
https://www.sci.utah.edu/~wald/Publications/2008///BSP/download//bsp.pdf
The resulting data structure is called a binary space partitioning tree or BSP tree. The flexibility to place splitting planes where they are most ef-fective allows BSP trees to adapt very well even to complex scenes and highly uneven scene distributions, usually making them highly effective. For a polygonal scene, a BSP tree can, for example ...

Ray tracing with the BSP tree Abstract: One of the most fundamental concepts in computer graphics is binary space subdivision. In its purest form, this concept leads to binary space partitioning trees (BSP trees) with arbitrarily oriented space partitioning planes. In practice, however, most algorithms use kd-trees-a special case of BSP trees ...

Within the field of computer graphics, it has applications in hidden surface removal and ray tracing. A BSP tree is a recursive sub-division of space that treats each line segment (or polygon, in 3D) as a cutting plane which is used to categorize all remaining objects in the space as either being in “front” or in “back” of that plane.

In collision detection or ray tracing, a scene can be divided up into some primitives on which collision or ray intersection tests are straightforward. Generation The canonical implementation of a BSP tree is for rendering polygons (that are double-sided, that is, without back-face culling) with the help of the painter's algorithm.

The BSP tree is built by InitBinTree() andSubdivide(), RayTreeIn- tersect() is the actual tree walking traversal of the BSP tree following a ray. These are the key functions necessary to implement the algorithm. Subdivide( ) builds the BSP tree by subdividing along the midpoint of the current node’s bounding volume.
Ray tracing with BSP and Rope trees
https://old.cescg.org/CESCG-2000/JKrivanek/index.html
Ray tracing is a widely used rendering technique for producing realistic images that simulate specular surfaces. It requires testing of many rays to determine intersection with objects. A way of reducing the computational cost of ray tracing is to minimize the occurence of one basic operation, the ray-object intersection test.
