Phong reflection model - HandWiki

WebOne of the most common reflection models is the Phong model. [13] The Phong model assumes that the intensity of each pixel is the sum of the intensity due to diffuse, specular, and ambient lighting. [16] This model takes into account the location of a viewer to determine specular light using the angle of light reflecting off an object. [17] WebThe above is the implementation of the Phong lighting model in Unity, and there is another implementation method of high light reflection - the Blinn lighting model, which does not use the reflection direction, but introduces a new vector h. The Blinn model calculates the specular reflection formula as follows: fixed4 ...

WebIn the Cook-Torrance specular reflection model shown in Equation (10), the geometrical attenuation coefficient (G) is regarded as a constant 1 because it has little effect, as described above. Also, the normal distribution function (D), normal vector (N), illumination vector (L), and line-of-sight vector (V) are known, and π is a constant. ...
