Bounding Volume Hierarchy (BVH) is a popular ray tracing acceleration technique that uses a tree-based “acceleration structure” that contains multiple …
Interactive k-D Tree GPU Raytracing - Stanford University
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, …
k-d Trees For Raytracing - TU Wien
https://www.cg.tuwien.ac.at/studentwork/VisFoSe98/jiri/index.htm
The depth of tree can be (in general case) decreased using so-called relaxed k-d (r-k-d) trees ( Slide 6 ) which allow the discriminants (partitioning plane orientations) be arbitrary. In case of r-k-d trees, the depth is usually less (Slides 7 and 8 ), so such a structure is used for raytracing purposes instead of the originally proposed one.
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.
The Ray Tree - Computer Graphics at Stanford University
https://graphics.stanford.edu/~cek/rayshade/doc/guide/section2_4_5.html
The Ray Tree. When ray tracing a scene, reflected or transmitted rays may strike other reflective or transparent objects. Further reflected or transmitted rays will be spawned, and so on. Taken together, such a family of rays is termed the ray tree. Care must be taken to control the depth of this tree: If it is allowed to grow too deeply, one ...
Ray Tracing Complex Objects Using Octrees - Swarthmore …

tree- each node having exactly 8 children save for the leaf nodes. This way of organizing space will allow our ray tracer to run more quickly as we may divide each object in the scene into "nodes" and instead of linearly searching for hits on objects we may instead narrow searches down to a few "pierced" nodes.
KD tree optimization for path tracing - GitHub
https://github.com/reddeupenn/kdtreePathTracerOptimization
in Solution Explorer right-click on kdtreePathTracerOptimization select Set as StartUp Project. Ctrl+F5 builds and runs the code. You will not see anything initially because you need to supply a scene file and / or an obj file. There are 2 ways of doing this, either in the command line like so:
raytracing - Kd tree for triangle meshes is too slow - Stack …
https://stackoverflow.com/questions/20019110/kd-tree-for-triangle-meshes-is-too-slow
The probability of intersection of the ray with subtree - is proportional to the surface area of the bounding box of that subtree. But, if leaf-subtree contains lots of triangles - it means that we have to traverse them all. So, the main idea of SAH is to minimize both: surface areas of subtrees and number of polygons inside of them.
Review: Kd-tree Traversal Algorithms for Ray Tracing
https://dcgi.fel.cvut.cz/home/havran/ARTICLES/cgf2011.pdf
A kd-tree [Ben75] is one of the hierarchical data struc- tures often used for ray tracing algorithms. It is a special case of a BSP tree [FKN80], recursively partitioning space with planes that are perpendicular to the axes of a coordi- nate system. Every inner node of the tree has a defined split- ting plane, which creates two separate half-spaces.
Megascans Trees are now in early access - quixel.com
https://quixel.com/blog/2021/12/15/megascans-trees-are-now-in-early-access
Megascans Trees are now in early access. Today we’re introducing the long-awaited early access of ‘Megascans Trees’, a brand new asset type unlike any we’ve released before. Far from being ‘just another type of foliage’, our first pack, available on the Unreal Engine Marketplace for free, is the culmination of extensive research ...
