Accurate analytic approximations for real-time specular area lighting
I3D, pp. 113-120, 2016.
We introduce analytic approximations for accurate real-time rendering of specular surfaces lit by area light sources. Our solution leverages the Irradiance Tensors developed by Arvo for the rendering of Phong surfaces lit by a polygonal light source. Using a reformulation of the 1D boundary edge integral, we develop a general framework fo...More
