We hope that the proposed ideas will provide other researchers and develop-
ers with tools to tackle problems of area lights and further extend the concept.
In future, we hope that area-based lighting will become the de facto standard
in modern video games, providing unified, predictable lighting solutions supple-
menting physically based material reflectance models.
