Shading with area lights adds a great deal of realism to CG renders. However, it requires solving spherical equations that make it challenging for real-time rendering. In this project, we develop a new spherical distribution that allows us to shade physically based materials with polygonal lights in real-time.

and in “2 min. papers” (supposedly tested with/on Unity?)
Will we see it in Blender?
