Such bounding boxes arise frequently in spatial subdivision problems, such as in ray tracing or collision detection. One common way to specify such a box is to provide two points Pmin = [ xmin ymin zmin] and Pmax = [ xmax ymax zmax ], as shown in Figure 11.61. Sign in to download full-size image Figure 11.61.

The technique of using spatial subdivision for accelerating ray tracing has gone on to be further developed by many researchers who have taken the approach to levels of sophistication I never dreamed of. The technique is also used, in one form or another, in many commercial products.

The ray-tracing method named BSS is based on two levels of spatial subdivision : The solid level spatial subdivision divides the whole transport space into hierarchical tree, in which every leaf node contains a limited amount of solids, to make the solids involved in a single ray tracing step few. The facet level spatial subdivision divides the bounding box of each solid …

However, my calculations are not accurate and for this I must use Ray tracing-spatial subdivision. Anyway, Is there any sample that uses this method in the samples? Is there a command or context related to Ray tracing-spatial subdivision? I know how to implement such a thing, but I was wondering if there was such a sample or context before that.

space subdivision for ray tracing. It begins with the basic geometry and alge bra of rays and planes, and then introduces the idea of a bounding volume. Next a description of the two major hierarchical data structures for ray tracing is given, with emphasis on space subdivision hierarchies. Finally, a survey of
