In this paper we use a bounding volume hierarchy (BVH) [Ru- bin and Whitted 1980] to interactively ray trace a particular type of dynamic scene:deformable scenes. A deformable scene is …

While the best reported frame rates for static geometric models have been achieved using carefully constructed kd-trees, this article shows that bounding volume hierarchies (BVHs) can be used to efficiently ray trace large static models.More importantly, the BVH can be used to ray trace deformable models (sets of triangles whose positions change over time) with little loss …

Third, packets of rays are traced together through the BVH allowing rapid hierarchy descent for packets that hit bounding volumes, and rapid exits for packets that fully miss. A BVH-based ray tracer is described with performance on deformable models comparable to that previously available only for static models. Keyphrases

Looking at recent projects on ray tracing software packages [3,4], the current baseline of acceleration structure for static scenes seems to be the bounding volume hierarchy (BVH) constructed with ...

This restriction is due to the static nature of the acceleration structures used. While the best reported frame rates for static geometric models have been achieved using carefully constructed kd-trees, this article shows that bounding volume hierarchies (BVHs) can be used to efficiently ray trace large static models.

Third, and most importantly, packets of rays are traced together through the BVH using a novel integrated packet-frustum traversal scheme. This traversal scheme elegantly combines the advantages of both packet traversal and frustum traversal and allows for rapid hierarchy descent for packets that hit bounding volumes as well as rapid exits for packets that miss.

The most significant deficiency of most of today's interactive ray tracers is that they are restricted to static walkthroughs. This restriction is due to the static nature of the acceleration struc...

Ray-tracing with Bounding Volume Hierarchies. When naively raytracing (with triangle primitives), for n rays and m triangles there are mn intersection tests, as every ray must check for intersection with every triangle in the scene (ignoring triangle culling). This cost can be reduced with a spatial partitioning data structure, which groups primitives that are close together.
