The Phong specular computations start with computing the direction to the camera. Since we are working in camera space, we know that the camera is at the origin (0, 0, 0). The direction from point A to point B is the normalization of B - A.

What he did was place L at infinity and make the surface a perfect reflector (that always reflected the maximum specular light) towards the view (where ever it was).

WebJul 16, 1999 · THE PHONG SHADING MODEL The idea behind phong shading is to find the exact color value of each pixel. In its most common form, the phong shading model is as follows : 1) determine a normal vector at each vertex of a polygon, the same normal vector used in gouraud shading. 2) interpolate normal vectors along the edges of the polygon.
