Hierarchical bounding volumes
Webapplications: bounding volume hierarchies and Lightcuts [23, 21]. In the next section, we briefly discuss some related work. Then we discuss general algorithms for agglomerative clustering in Sec-tion 3 and present our locally-ordered algorithm that is faster than traditional heap-based ones and easier to parallelize. Section 4 ap- WebAn overview of available visibility and occlusion culling methods. Unreal Engine provides methods of culling for visibility and occlusion. These culling methods are useful for optimizing game performance. Each method works to reduce the number of visible Actors in the Level by setting whether they should be drawn to the screen or not.

WebIn this paper, a collision detection optimization algorithm based on hybrid bounding volumes is presented to improve the real-time ability of bounding volumes collision detection. The algorithm combines the simplicity of AABB-AABB overlap test with the tightness of k-dops. Bounding volumes binary trees of the objects are designed as … WebOn BVH trees, each node has a bounding volume that encloses the bounding volumes of all its childrens. Those bounding volumes are often axis aligned to reduce the com …
Web9 de nov. de 1999 · This algorithm maintains the scene model in an octree, and a frame's Z-buffer as an image pyramid, which we call a Z-pyramid. The octree enables hierarchical culling of occluded regions of the scene, and the Z pyramid enables hierarchical Z-buffering of individual primitives and bounding volumes. http://www.ee.technion.ac.il/~ayellet/Ps/TSTD-06.pdf
