Plenoptic Function

The Plenoptic Function is a concept in imaging and vision that represents all the visual information available in a scene from every possible viewpoint and for every possible direction of light. Imagine a complete 3D snapshot of the world around us, capturing how light interacts with objects at different angles and distances. This function captures details like color, brightness, and depth, allowing for an understanding of how we perceive scenes. Essentially, it’s a comprehensive way to describe how light travels and interacts in any environment, which is crucial for fields like photography, computer graphics, and virtual reality.
