For many scenes, we can assume the air is transparent so that the radiance is consistent along the ray. | For many scenes, we can assume the air is transparent so that the radiance is consistent along the ray. | ||
In these situations, light fields can be reduced to 4D functions defined only on rays in some enclosed scene. | In these situations, light fields can be reduced to 4D functions defined only on rays in some enclosed scene. | ||
You can create a 4D parameterization using a two plane parameterization, typically represented as <math>(s,t,u,v)</math> or a (plane, angle) parameterization to define each ray. | You can create a 4D parameterization using a two plane parameterization, typically represented as <math>(s,t,u,v)</math>, or a (plane, angle) parameterization to define each ray. | ||
