Phong shading improves upon Gouraud shading and provides a better approximation of the shading of a smooth surface. Phong shading assumes a smoothly varying surface normal vector. The Phong interpolation method works better than Gouraud shading when applied to a reflection model with small specular highlights such as the Phong reflection model. The most serious problem with Gouraud shading occurs when specular highlights are found in t… churches in scottsville kyWebFigure 3.42 shows the progression: (a) traditional Phong shading; (b) using their shading model with highlights and a cool-to-warm hue shift; (c) adding edge lines and highlights; … development of the ungp

"WebThe Phong shading can also include a Fresnel term in order to heavily favor rim lighting cases as opposed to general specular highlights. Under very bright lights, the specular rim highlights are often bright enough to bloom out in a dramatic fashion as a result of the Source engine's normal HDR post-processing.

The following image shows this graphically: L is the vector from the light to the vertex being shaded. N is the normal vector, and Eye is the vector from the vertex to the eye, or camera.

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.
