Ray Tracing Using k-D Tree
 Šilhavý, Miroslav ; Herout, Adam (referee) ; Havel, Jiří (advisor)
This thesis deals with ray tracing methods and their acceleration. It gives partial study and review of algorithms from classical ray shooting algorithm to recursive approach up to distributed ray tracing algorithm. Significant part of this thesis is devoted to BSP tree structure and its subclass of k-D tree, it shows simple algorithm for its construction and traversal. The rest of thesis is dealing with k-D tree construction techniques, which are based on the right choice of the splitting plane inside the every cell of k-D tree. The techniques upon the thesis is based on are space median, object median and relatively new cost model technique named SAH, otherwise as surface area heuristic. All three techniques are put into testing and performance comparison. In the conclusion the results of tests are reviewed, from where SAH is coming out as a winner.
