NettetWe will build our approach around a bounding volume hierarchy (BVH), which is a commonly used acceleration structure in ray tracing (for example). A bounding volume hierarchy is essentially a hierarchical grouping of 3D objects, where each group is associated with a conservative bounding box.

NettetBounding volume hierarchies allow one to determine quickly if two objects are not in close proximity. The further apart the objects are, the less traversal the methods have to do and thus the less work in determining the proximity between the objects. Current bounding volume hierarchy methods use explicit bounding volumes like spheres, axis ... Nettetexample hierarchies of bounding volumes, that have to be computed in a preprocessing phase and that are strictly connected with the shape of the objects, which is a con-stant of the system. Generally speaking, the quality of a strategy that uses bounding volumes is inﬂuenced by two factors: how well the bounding volume approximates the ob-ject christina applegate younger years

"NettetWe propose a new massively parallel algorithm for constructing high-quality bounding volume hierarchies (BVHs) for ray tracing. The algorithm is based on modifying an existing BVH to improve its quality, and executes in linear time at a rate of almost 40M triangles/sec on NVIDIA GTX Titan.

Simplified models, besides their application to multiresolution rendering, can provide clues to the object’s shape. These clues help in the partitioning of the object’s model into …

A bounding volume hierarchy (BVH) is a tree structure on a set of geometric objects. All geometric objects, which form the leaf nodes of the tree, are wrapped in bounding volumes. These nodes are then grouped as small sets and enclosed within larger bounding volumes. These, in turn, are also grouped and … Se mer The choice of bounding volume is determined by a trade-off between two objectives. On the one hand, we would like to use bounding volumes that have a very simple shape. Thus, we need only a few bytes to store them, and Se mer There are three primary categories of tree construction methods: top-down, bottom-up, and insertion methods. Top-down methods proceed by partitioning the input set into two (or more) subsets, bounding them in the chosen bounding volume, then keep … Se mer • BVH in Javascript. • Dynamic BVH in C# • Intel Embree open source BVH library Se mer BVHs are often used in ray tracing to eliminate potential intersection candidates within a scene by omitting geometric objects located in … Se mer • Binary space partitioning, octree, k-d tree • R-tree, R+-tree, R*-tree and X-tree • M-tree • Scene graph Se mer Nettet3.
