Smooth shading • Gouraud shading • Phong shading Recall that OpenGL handles only triangles. So the terms “polygon” and “polygonal” from here onward should be interpreted as “triangle” and “triangular”. 13 Gouraud shading and Phong shading are both smooth shading techniques.

WebApr 16, 2024 · Per-pixel lighting is also known as Phong shading (in contrast to per-vertex lighting, which is also known as Gouraud shading). This should not be confused with the Phong reflection model (also called Phong lighting), which computes the surface lighting by an ambient, a diffuse, and a specular term as discussed in Section “Specular Highlights”.
