Computational Hologram Generation Based on Unity 3D-Model

Unity has powerful 3D model processing capa-bilities, which makes it convenient to extract 3D models. In this paper, we propose a method to obtain a 3D point source model based on the Unity platform and connect it to the CGH for hologram generation. The method uses a Unity plug-in to extract the model and relies on the basic principles of computational hologram and Burch coding to generate a computational hologram of the 3D point source model. Particularly, this paper uses the control variable method to construct experiments with respect to different influence parameters, and then processes and analyzes the generated data, draws the influence rate curve, and finally draws the conclusion: Under the limited computational conditions, the time of generating hologram increases with the continuous expansion of each parameter. Model size and hologram size have the most pronounced effect on the time consumption. When the parameters are tiny, the computational hologram can be implemented directly, while when the parameters are large, the model data needs to be processed as a transition to implement the computational hologram.
