Ray Tracing Complex Objects Using Octrees - Swarthmore …
https://www.cs.swarthmore.edu/~jcarste1/pdfs/octree.pdf
Ideally a ray will enter one octree root, determine which child it hit, then which child of that child it hit, and so on. The higher depth to which we de ne our tree, the more nodes there will be and thus the program will theoretically run faster and faster as depth increases.

Here's what it looks like when I stop at the root bounds, without using the DDA to traverse the tree: /* find which leaf, if any, the ray intersects. Returns transparency (Color (0,0,0,0)) if no intersection was found. TestValue is a shader constant parameter passed from the caller which is used to dynamically adjust the number of loops the ...

The problem of selecting the correct octant while using the commonly available floating-point arithmetic is also addressed in a ray tracing environment. Comparisons of this approach with the method given by Samet 17 are carried out in a variety of cases involving millions of voxels. The improvement ranged from 32% to 62% in terms of execution time.

Ray tracing[19] is an image rendering technique that models light as particles moving in the scene. In this paper we focus on the use of hierarchical data structures such as the octree to speed up the determi- nation of the objects that are intersected by rays em- …
Octree-R: an adaptive octree for efficient ray tracing
https://ieeexplore.ieee.org/abstract/document/485621/
Ray tracing requires many ray-object intersection tests. A way of reducing the number of ray-object intersection tests is to subdivide the space occupied by objects into many nonoverlapping subregions, called voxels, and to construct an octree for the subdivided space. We propose the Octree-R, an octree-variant data structure for efficient ray tracing. The algorithm for …

For general ray tracing, octrees lack the nonrecursive traversal of grids, or ability of kd-trees and BVHs to adapt to overlapping polygonal scene geometry. Volume rendering, however, guarantees regularly-spaced, non-overlapping voxels, which are directly used to …
4, Octree-R: An Adaptive Octree for Efficient Ray Tracing
https://dblab.kaist.ac.kr/Prof/pdf/Whang1995.pdf
In this paper, we propose the Octree-R, an octree-variant data structure for efficient ray tracing. The algorithm for constructing the Octree-R first estimates the num- ber of ray-object intersection tests. Then, it partitions the space along the plane that minimizes the estimated number of ray- object intersection tests.
