Lambertian Surface Appears equally bright from all viewing directions Reflects all light without absorbing Matte surface,no "shiny"spots Brightness of the surface as seen from camera is linearly correlated to the amount of light falling on the surface Here we will discuss only Lambertian surfaces under point-source illuminationLambertian Surface ▪ Appears equally bright from all viewing directions ▪ Reflects all light without absorbing ▪ Matte surface, no “shiny” spots ▪ Brightness of the surface as seen from camera is linearly correlated to the amount of light falling on the surface Here we will discuss only n Lambertian surfaces under point-source illumination
