WebbA polygon surface is rendered using Phong shading by carrying out the following steps: Determine the average unit normal vector at each polygon vertex. Linearly & interpolate … Webb26 juli 2024 · The Phong reflection model is an empirical (so based on observations) local illumination model. Let's see how we is it composed. In real world light is modeled by its spectrum, and each surface by its reflectance spectrum. In computer graphics often an approximation based on RGB triplets is used:
