WebMay 2, 2024 · In contrast, Phong shading is a per-fragment color computation. The vertex shader provides the normal and position data as out variables to the fragment shader. The fragment shader then interpolates these variables and computes the color. Here is an illustration of the Phong Shading: The Phong Shading vertex shader:
