WebSpecular lighting: sets a specular highlight the closer the viewer is looking at the reflection of a light source on a surface. Based on the viewer's direction, the light's direction and a shininess value that sets the amount of scattering of the highlight. Phong shading: the Phong lighting model applied in the fragment shader. WebMay 22, 2024 · Illumination model, also known as Shading model or Lightning model, is used to calculate the intensity of light that is reflected at a given point on surface.

WebJul 18, 2015 · 2. The equation is a consequence of the symmetry of the reflection of the light about the normal: We know from the law of reflection that the angle between R and N is the same as the one between L and N. Therefore it's also clear that: R•N = L•N (assume all are unit vectors) From symmetry, it's also evident that.
