Ray Tracing with the Single Slab Hierarchy

structure for ray tracing which offers favorable speed and very low memory consumption. The sin-gle slab hierarchy (SSH) is a binary object partition-ing scheme, resulting in a binary tree. Similar to BVHs a ray traverses this tree in a top-down fash-ion. If it does not intersect one of the nodes, the whole subtree can be skipped (see Sect. 3.4). In-

To compare and discuss the numerical characteristics of those methods, a semitransparent slab with variable spatial refractive index is taken as an example, and the reflectivity and the transmissivity of the slab are computed by the curved ray-tracing method, the multi-layer approach, and the discrete curved ray-tracing method, respectively.

A discrete curved ray-tracing method is developed to analyze the radiative transfer in one-dimensional absorbing–emitting semitransparent slab with variable spatial refractive index.

https://tavianator.com/2011/ray_box.html
The fastest method for performing ray/AABB intersections is the slab method . The idea is to treat the box as the space inside of three pairs of parallel planes. The ray is clipped by each pair of parallel planes, and if any portion of the ray remains, it intersected the box.

TLDR The advantage of this method is its capability to trace rays through a medium with random refractive distribution in an accurate way, and it is shown that for appropriate parameter settings this method can obtain great accuracy. 5 Radiative heat transfer in variable refractive index slab media using Pomraning–Eddington approximation

To fix the problem, we can replace the ray direction by the inverse of the ray direction: Vec3f invdir = 1 / ray.dir; if (invdir.x >= 0) { tmin = (min.x - r.orig.x) * invdir.x; tmax = (max.x - r.orig.x) * invdir.x; } else { tmin = (max.x - r.orig.x) * invdir.x; tmax = (min.x - r.orig.x) * invdir.x; }

Show activity on this post. Actually, I've ever read the algorithm described here: http://www.siggraph.org/education/materials/HyperGraph/raytrace/rtinter3.htm This algorithm can decide whether a ray hit the axis-aligned box. In the algorithm, it computes the intersection distance of the planes, that is: T1 = (boxmin - o) / d T2 = (boxmax - o) / d boxmin (xl,yl,zl) is the …
A Ray-Box Intersection Algorithm
https://www.jcgt.org/published/0007/03/04/paper-lowres.pdf
based ray intersection, on which modern high-performance ray-casting algorithms are built. For over a decade, the Kay and Kajiya [1986] slabs method has been the dominant algorithm, but the details of the code for implementing this algorithm have changed significantly. A variety of other methods have been used on the CPU.
