Computer-generated hologram (CGH) is hologram in which interference fringe is computed by a computer, and the CG data must be converted into a point cloud for CGH computation. Our group proposed a point cloud generation method using photon maps (PM method), which can generate realistic point clouds by using photons, which are light particles, but it takes a lot of time to generate point clouds. However, it took a long time to generate the point cloud, and a method using Unity was proposed (U2Dat), which enabled fast and realistic point cloud generation, but had problems in representing reflections and refractions, which were possible with the PM method. In this research, ray tracing is introduced to the point cloud generation method using Unity, and the point cloud is moved by reflection and refraction to generate a fast and realistic point cloud. The realism of CG data is also improved by modifying the Unity rendering environment. |
