WebMar 24, 2024 · You're interpolating the normal as a varying variable, so the fragment shader should receive the correct per-pixel normal. The only explanation (I can think of) of the fact that you're having the result as on your left image is that every fragment on a given face ultimately receives the same normal. You can confirm it with a fragment shader like: WebJan 25, 2024 · The most known ones are the Gouraud lighting model and the Blinn-Phong. The Gouraud lighting model is just the Phong model applied to vertex of a polygon (instead of pixels) and using linear interpolation to calculate the color of the points between the pixels.
