Phong algorithm
WebFeb 10, 2010 · Technically ray tracing really only determines visibility and distance. Recursively it can be used for reflections, refractions, and shadows (checking light source visibility). Stochastic ray tracing or photon mapping can simulate light scattering. Phong and Gouraud shading are reflection models applied to at a surface.

WebPhong is a very basic, but real looking light model for surfaces that has three parts: ambient, diffuse, and specular lighting. Ambient Lighting: Ambient lighting is the simplest of the three parts to understand and calculate. Ambient lighting is light that floods the scene and lights up the object evenly in all directions. WebPhong 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

WebPhong Shading A more accurate method for rendering a polygon surface is to interpolate the normal vector and then apply the illumination model to each surface point. This method developed by Phong Bui Tuong is called … WebEDIT: I misunderstood your question, so please disregard this answer. The Phong shading model assumes a surface normal $\mathbf{n}$ at the shading point $\mathbf{x}$ but it is independent of its type, so either the shading normal or the geometric normal will work.Moreover, this reflectance model requires an incoming and outgoing directions.
