Sažetak
Computer-generated holography is method of using numerical methods to simulate the physical processes underlying a real hologram’s optical recording and reconstruction ie. is the method of digitally generating holographic interference patterns. And as such, it represents substantial progress compared to classical holography. Since the desired wavefront is obtained using numerical methods, the real object becomes redundant and is replaced by a virtual 3D object created using 3D modeling tools. A major disadvantage of this approach is the absence of specialized software tools for computer-generated holograms and extremely high computer resource consumption, resulting in a very long time of computing. The paper presents a new method of computer generating hologram that uses dense point clouds as input object. The goal of this paper is to create a physically plausible computer model for generating holograms, with a large potential for calculation optimization and acceleration, as well as the integration of this model into simple hologram creation software. We made software that simulates wave optics using previously known physical model to generate a hologram with possibility of connection with commercial 3D tools via .obj documents. Considering that there is a problem of high consumption of computing resources and time we have incorporated in our software the possibility of a parallel calculation for the purpose of testing and designing further development of the software. For the purposes of realization of the software we made research on the physical model, and the obtained results made possible customization to optimize the computer generation of holograms.
