Abstract: Computing direct illumination from area light sources involving shadowing remains a perrenial and yet difficult problem in rendering. Illumination is formalized as the radiometric quantity of irradiance and is a function of surface position. This work investigates the irradiance surface function, and develops closed-form expressions for shadowed irradiance in polygonal and polyhedral environments illuminated by polygonal light sources. Using the mechanism of polyhedral splines, a closed-form... (Update)
