Holograms, either optically acquired or simulated numerically from 3D datasets, such as point clouds, have
special rendering requirements for display. Evaluating the quality of hologram generation techniques is not
straightforward, since high-quality holographic display technologies are still immature, In this paper we present
a framework for three-dimensional rendering of colour computer-generated holograms (CGHs) acquired from
point-clouds, on high-end light field displays. This allows for the rendering of holographic content with horizontal
parallax and wide viewing angle. We deploy prior work, namely a fast CGH method that inherently handles
occlusion problems to acquire high quality colour holograms from point clouds. Our experiments showed that
rendering holograms with the proposed framework provides 3D effect with depth disparity and horizontal-only
with wide viewing angle. Therefore, it allows for the evaluation of CGH techniques regarding functional properties
such as depth cues and efficient occlusion handling.
