WebBlinn–Phong is the default shading model used in OpenGLand Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixelvalues between vertices are interpolated by Gouraud shadingby default, rather than the more computationally-expensive Phong … WebMay 11, 2024 · For Phong shading, you do want to keep the normalize on the end; that's the key thing that makes Phong different from Gouraud shading. But also, normalize isn't part of the usual definition of "lerp" (linear interpolation), so I would keep it out of the lerp function, and move the normalize to the Phong shading function where you call lerp.

Web2. 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. The difference will be clear in the coming slides.
