🌐 Introduction to Light Field

The concept of a light field, also known as a lightfield, has been gaining significant attention in recent years due to its potential to revolutionize the way we perceive and interact with visual information. A light field is a physical field that describes the amount of light flowing in every direction through every point in a three-dimensional space, as described in the work of Light Field Research and Optics and Photonics. The mathematical space of all possible light rays is given by the five-dimensional Plenoptic Function, and the magnitude of each ray is given by its Radiance. This concept has far-reaching implications for fields such as Computer Vision and Image Processing.

📸 The Plenoptic Function: A Mathematical Representation

The plenoptic function is a mathematical representation of the light field, which describes the distribution of light in a scene.
