Blinn-Phong Shading is a popular shading model used in computer graphics to simulate the way light interacts with surfaces. It combines three components: ambient, diffuse, and specular reflections. The ambient component provides a base level of light, while the diffuse component simulates the scattering of light on rough surfaces. The specular component creates highlights, giving the appearance of shiny surfaces. This shading model is an extension of the Phong Shading model, improving the calculation of specular highlights by using a halfway vector between the light source and the viewer. This results in more realistic rendering of shiny surfaces, making it widely used in 3D graphics and game design.
