Phong reflection
WebWhile Phong shading is a per-pixel shading with normal interpolation, the Phong reflection model or the alternative Blinn–Phong shading model, though called differently, can be used at vertices and interpolated with Gouraud shading .

The other component is calculated via the equation from the Phong reflection model. Our ray tracer currently adds both components as in (1 - reflectivity) * color + reflectivity * trace (reflected_ray, depth + 1) where color is determined by the Phong equation.
