Benchmarking results indicate that when used with axis-aligned bounding parallelepipeds, this method of ray tracing is one of the fastest known. A hierarchical search structure for ray tracing based on k-d trees is introduced that can handle the variety of surfaces commonly used in computer graphics and is one of the fastest known.

ent packet tracing [30, 26] and frustum traversal [17] kd-trees are increasingly believed to be the “best known method” for fast ray tracing [20]. Both concepts become particularly interesting if the kd-tree is built to minimize the number of traversal and intersection steps, which today is usually done using a heuristic cost estimate, the Surface Area Heuristic (SAH) [13]. Kd-trees have …

Kd-Tree Based Fast Ray Tracing for RCS Prediction
https://www.jpier.org/PIER/pier.php?paper=08011305
Abstract. Ray tracing is of great use for computational electromagnetics, such as the well-known shooting and bouncing ray (SBR) method. In this paper, the kd-tree data structure, coupled with the mailbox technique, is proposed to accelerate the ray tracing in the SBR. The kd-tree is highly effective in handling the irregularly distribution of patches of the target, while the repeatedly …

1. 3. In a 3 dimensional kD tree, the split-axis is X, Y, or Z. The split-plane is the actual plane used to split the children. It is always perpendicular to an axis, with some given displacement from the origin. – Tavian Barnes. Apr 22, 2013 at 19:13.

k-d Trees For Raytracing

k-d tree , as proposed by Bentley is a structure for fast searching in multidimensional spaces. Just for better interpretation, in case of raytracing, the space to be searched in is mostly 2 or 3 dimensional Euclidean Space ( Slide 5 ).

3. Fast construction of kd-trees Using high-quality kd-tree is essential for achieving interac-tive ray tracing performance. Therefore, the goal is building a kd-tree as fast as possible minimizing its quality degrada-tion. A typical kd-tree construction proceeds in a top-down fashion by recursively splitting a current node into two sub-
