The most complete representation is the 7D plenoptic function, P(x, y, z, θ, φ, λ, t), describing the radiance of light at any 3D point (x,y,z), in any direction (θ, φ), for any wavelength (λ), at any time (t).<ref name="AdelsonBergen1991"/> For many applications, this is overly complex and contains redundant information (for example light doesn't typically change along a straight ray in free | The most complete representation is the 7D plenoptic function, P(x, y, z, θ, φ, λ, t), describing the radiance of light at any 3D point (x,y,z), in any direction (θ, φ), for any wavelength (λ), at any time (t).<ref name="AdelsonBergen1991"/> For many applications, this is overly complex and contains redundant information (for example light doesn't typically change along a straight ray in free space, radiance invariance, unless wavelength or time are critical).<ref name="WikiLF"/> | ||
