Abstract: PURPOSE: A KD tree creation method using a hardware and apparatus thereof are provided to support dynamically a video by creating a KD tree for a acceleration structure. CONSTITUTION: A cost calculation unit(310) reads triangle data from a memory by referencing the index of list data and searches the minimum cost location of a current node based on the triangle data. A left and right classification unit(320) classifies a right direction and a left direction based on the location. In case the cost calculation unit does not search the minimum cost location, a tree creation unit(330) creates an internal node based on a pop operation about a stack and creates a leaf node.
