A '''light field''' (also spelled '''lightfield''') is a fundamental concept in [[optics]] and [[computer graphics]] that describes the amount of [[light]] traveling in every direction through every point in [[space]].<ref name="LevoyHanrahan1996">Levoy, M., & Hanrahan, P.

Understanding and utilizing light fields is crucial for advancing [[virtual reality]] (VR) and [[augmented reality]] (AR) technologies, as it allows for the capture and reproduction of visual scenes with unprecedented realism, including effects like [[parallax]], [[reflection]]s, [[refraction]]s, and [[refocusing]] after capture, while also aiming to solve critical issues like the [[vergence-accommodation conflict]].<ref name="Ng2005">Ng, R.
