WebbPhong Illumination Model • Calculate color for arbitrary point on surface • Basic inputs are material properties and l, n, v: l = vector to light source n = surface normal v = vector to viewer r = reflection of l at p (determined by l and n) Basic Calculation • Calculate each primary color separately • Start with global ambient light WebbSharp drop of intensity values on the polygon surface cannot be displayed. Phong Shading :-Phong shading, also known as normal-vector interpolation shading, interpolates the surface normal vector N, instead of the intensity. By performing following steps we can display polygon surface using Phong shading. 1.
