Octree-R: an adaptive octree for efficient ray tracing Abstract: Ray tracing requires many ray-object intersection tests. A way of reducing the number of ray-object intersection tests is to subdivide the space occupied by objects into many nonoverlapping subregions, called voxels, and to construct an octree for the subdivided space.

In this paper, we propose the Octree-R, an octree-variant data structure for efficient ray tracing. The algorithm for constructing the Octree-R first estimates the num- ber of ray-object intersection tests. Then, it partitions the space along the plane that minimizes the estimated number of ray- object intersection tests.

The nal aspect of the Octree implementation is the ray-octree intersection that needs to be calculated in order to know which leaf nodes are pierced by a ray. This is done by taking the ray parametric function: r x(t) = p x + td x r y(t) = p y + td y r z(t) = p z + td z We know that an intersection has occured if there exists one t that satis es: x 0(o) r x(t) < x 1(o) y

Efficient intersection between rays and objects can be achieved by using acceleration structures such as octrees. The idea of an octree is to split the space into $8$ equal-sized octants (hence the name). The 2D variant of an octree is a quadtree. Analogous a binary tree can be considered to be the 1D variant of an octree and a quadtree.
