In particular, kd-trees built with cost estimation functions such as a surface area heuristic (SAH) seem to be important for reaching high performance. Unfortunately, most algorithms for building such trees have a time complexity of O(N log 2 N), or even O(N 2). In this paper, we analyze the state of the art in building good kd-trees for ray tracing, and eventually …

ent packet tracing [30, 26] and frustum traversal [17] kd-trees are increasingly believed to be the “best known method” for fast ray tracing [20]. Both concepts become particularly interesting if the kd-tree is built to minimize the number of traversal and intersection steps, which today is usually done using a heuristic cost estimate, the Surface Area Heuristic (SAH) [13]. Kd-trees have …

In this paper, we analyze the state of the art in building good kd-trees for ray tracing, and eventually propose an algorithm that builds SAH kd-trees in O(N log N), the theoretical lower bound Though a large variety of efficiency structures for ray tracing exist, kd-trees today seem to slowly become the method of choice.

3. Fast construction of kd-trees Using high-quality kd-tree is essential for achieving interac-tive ray tracing performance. Therefore, the goal is building a kd-tree as fast as possible minimizing its quality degrada-tion. A typical kd-tree construction proceeds in a top-down fashion by recursively splitting a current node into two sub-
