WebThey show a full implementation of the Blinn-Phong reflection equation being applied in three different ways. The first is flat shading - one color is used for one whole primitive (triangle). The second is Gouraud shading - reflection is only calculated at the vertices, and colors are interpolated. WebAnother subtle difference between Phong and Blinn-Phong shading is that the angle between the halfway vector and the surface normal is often shorter than the angle between the view and reflection vector. As a …

WebShading with reflection Let I(P, d) be the intensity seen along a ray. Then: I(P, d) = I direct + I reflected where I direct is computed from the Blinn-Phong model, plus shadow attenuation I reflected = k r I (Q, R) Typically, we set k r = k s. (k r is a color value.) 18 Reflection Law of reflection: i = r R is co-planar with d and N. 19
