Light fields are a concept in computer graphics and imaging that refer to the capture and representation of all the light rays in a given scene or space. This includes not only the intensity of light at each point in space, but also the direction and color of the light rays. By capturing and manipulating light fields, researchers are able to create more realistic and immersive visual experiences, such as in virtual reality environments or 3D displays. Light fields have applications in fields such as photography, computer vision, and augmented reality.
