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.

Why is it that interpolating normals produces a more realistic results, while interpolating the colors directly does not?

WebApr 7, 2024 · An empirical model for calculating the specular reflection range, invented by the Phong Bui Tuong is also known as Phong specular reflection model. This model sets the intensity of specular reflection directly proportional to the cosns(∅). The range of angle ∅ can lie between 0 ≤ ∅ ≤ 1. Where ns is a specular reflection parameter ... WebPhong Shading: A more accurate interpolation based approach for rendering a polygon was developed by Phong Bui Tuong. Basically the Phong surface rendering model is also called as normal-vector interpolation rendering. It interpolates normal vectors instead of intensity values. To render a polygon, Phong surface rendering proceeds as follows:
