Phong interpolation

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. WebDec 1, 2010 · Zigzag-shaped object shaded with a traditional Phong normal interpolation (left) and with modulated consistent normals (right). All per-vertex shading normals are …
