But it's worth the trouble: Moving from a regular grid to a naïve kd-tree implementation almost doubled the speed. Moving from a simple heuristic to the SAH doubled the speed again. So let's have a look at the actual implementation of the kd-tree construction algorithm. Building a kd-tree generally looks like this, in pseudo-code:

Using the kd-tree acceleration structures. The method of using the kd-tree acceleration structures is illustrated in RayTraceKd.cpp. The kd-tree code is written with a very general interface so it can be used by a variety of applications. If you are just using the RayTrace software for ray tracing, you can just use the code in RayTraceKd.cpp.
Interactive k-D Tree GPU Raytracing - Stanford …
https://graphics.stanford.edu/papers/i3dkdtree/gpu-kd-i3d.pdf
A typical k-d tree traversal algorithm takes a k-d tree, a binary tree of axis aligned splitting planes that partition space, and a ray as input and returns the rst triangle the ray intersects. Traversal walks the ray through the tree so that it visits leaf nodes, …
On building fast kd-Trees for Ray Tracing, and on doing that in …
https://my.eng.utah.edu/~cs6965/papers/kdtree.pdf
Though all these techniques have their merits, kd-trees recently seem to establish themselves as the most widely used technique. In particular since the appearance of fast – and kd-tree-based – coher-ent packet tracing [30, 26] and frustum traversal [17] kd-trees are increasingly believed to be the “best known method” for fast ray ...

The ideas behind ray tracing (in its most basic form) are so simple, we would at first like to use it everywhere. But it's not used everywhere. Ray tracing has been used in production environment for off-line rendering for a few decades now. That is rendering that doesn't need to have finished the whole scene in less than a few milliseconds.

Acceleration Structures •BKM is to use a kD-tree (AA BSP) •Previous BKM was to use a uniform grid –Only scheme with comparable speed –Performance is not robust –No packet tracing algorithm •Other grids, octrees, etc…just use a kD-tree. •Don’t use bounding volume hierarchies.
Kd tree for triangle meshes is too slow - Stack Overflow
https://stackoverflow.com/questions/20019110/kd-tree-for-triangle-meshes-is-too-slow
When ray-tracing a bunny of 5500 triangles, there are a lot of leaf nodes of 1 triangle and the last leaf node still contains 762 triangles. Is there a better partitioning algorithm (because mine is just an implementation of a Kd tree for single points converted to surfaces), that balances the tree?
