High-quality holographic video generation requires both high computational resources and time therefore, algorithms that can generate holographic videos efficiently will be soon in demand for dynamic holographic 3D displays. In this work, we present an algorithm that uses a motion compensation scheme - based on rotational transformation of wavefields [Appl. Opt. 47, D110 (2008)], to generate efficiently holographic frames. The effects of motions to the wavefield is analyzed, while video generation examples are provided to support our theory. We report acceleration of 10 times with regard to the ray tracing method, that can be further improved by parallelization of the computations, with a trade-off of energy loss of 10%.
