Dynamic bounding volume tree
WebExperiments show that for deforming triangle meshes the reconstruction time of the bounding volume hierarchies per frame can be reduced by an order of magnitude compared to previous approaches, which also results in a signican t speed-up in the total rendering time for many types of dynamically changing scenes. In this paper, we … WebJun 1, 2015 · A bounding volume is a common method to simplify object representation by using the composition of geometrical shapes that enclose the object; it encapsulates complex objects by means of simple volumes and it is widely useful in collision detection applications and ray tracing for rendering algorithms. A bounding volume is a common …

WebBounding volume hierarchies. BVHs are trees that store a closed bounding volume at each node. In addition, each internal node has references to child nodes, and each leaf node also stores a list of ge-ometric primitives. The bounding volume is guaranteed to enclose the bounding volumes of all its descendants. Each geometric prim- WebNov 5, 2014 · The BVH tackles this issue differently, because it does not use splitting planes. Instead a volume is subdivided by defining two potentially overlapping …
WebThis idea of bounding volumes seems similar to the dynamic bounding volume tree (a data structure similar to the quad tree) used in the broad phase of collision detection. The dbvt tree organizes bounding volumes hierarchically by managing to maintain the size of each bounding volume to be the same. Once a bounding box is too large, it ...

WebMay 5, 2011 · Abstract. We present an efficient algorithm for building an adaptive bounding volume hierarchy (BVH) in linear time on commodity graphics hardware using CUDA. BVHs are widely used as an acceleration data structure to quickly ray trace animated polygonal scenes. We accelerate the construction process with auxiliary grids that help us build …
WebJul 1, 2011 · Recent developments have produced several techniques for interactive ray tracing of dynamic scenes. In particular, bounding volume hierarchies (BVHs) are efficient acceleration structures that ... gpu temperature checkerWebA bounding interval hierarchy (BIH) is a partitioning data structure similar to that of bounding volume hierarchies or kd-trees.Bounding interval hierarchies can be used in high performance (or real-time) ray tracing and may be especially useful for dynamic scenes.
