Lessons Learned from Implementing Light Field Camera Animation: Implications, Limitations, Potentials, and Future Research Efforts

Abstract

Among the novel 3D visualization technologies of our era, light field displays provide the complete 3D visual experience without the need for any personal viewing device. Due to the lack of such constraint, these displays may be viewed by any number of observers simultaneously, and the corresponding use case contexts may also involve a virtually unlimited numbers of users; any number that the valid viewing area of the display may accommodate. While many instances of the utilization of this technology operate with static contents, camera animation may also be relevant. While the topic of light field camera animation has already been addressed on an initial level, there are still numerous research efforts to be carried out. In this paper, we elaborate on the lessons learned from implementing light field camera animation. The paper discusses the associated implications, limitations, potentials, and future research efforts. Each of these areas are approached from the perspectives of use cases, visual content, and quality assessment, as well as capture and display hardware. Our work highlights the existing research gaps in the investigated topic, the severe issues related to visualization sharpness, and the lack of appropriate datasets, as well as the constraints due to which novel contents may be captured by virtual cameras instead of real capture systems.
