WebMar 16, 2024 · Phong is one of those things that refuses to go away. It has been patched to work somewhat as a BRDF [1] and despite the fact we have physically based specular lobes that look much better we keep going back, I guess it is nostalgia, revisiting those good old days when a render required a real camera and building a cornell box out of plywood.
BRDFs can be measured directly from real objects using calibrated cameras and lightsources; however, many phenomenological and analytic models have been proposed including the Lambertian reflectance model frequently assumed in computer graphics.
