A fast animation generation system for computer­generated hologram using ray-tracing method

CGH is a technique that simulates the recording of holography. Although CGH has a lot of advantages, it also has many disadvantages, such as a long computation time and difficulty in generating animation. In this research, we introduce an animation system for CGH that can realize the complex movements of multiple objects with a fast calculation method. The experiments demonstrate the effectiveness and high-speed calculation of the animation system.
