WebPhong shading Lambertian shading in the fragment shader •Shade (v.): determine color of a pixel •Shader (n.): a program that runs on GPU •Shading model (reflection or illumination model): light interaction model that determines a pixel's color •Shading algorithm (interpolation technique): when in which shader is the reflection model WebDec 2, 2024 · For Phong, the normals are interpolated first and the shading is evaluated per pixel. Also note there's a bit of an overloaded term between the Phong Lighting/Reflection model and Phong Interpolation, Per-pixel shading which is what you're referring to here. Given these 3 shading types, the next logical step is actually normal maps shading.
