The Research on the ray tracing algorithms Base on GPU

Scientific visualization, computer 3-D (Three dimension) animation and virtual reality are the three major research directions in computer graphics, and the core technology is 3D realistic graphics. Propelled by the game industry; GPU (Graphics Processing Unit) performance rate is doubled per year. In order to achieve more realistic graphics effect, more and more complex operations are supported by CPU. GPU computing architecture beats the CPU in the cost and power consumption. In this paper, Current status of GPU and ray tracing algorithms are introduced, constructing 3-D scene on the division algorithm by KID-Tree is presented. Eventually, deficiencies are summarized; further research and improvement are pointed out.
