WebThe Phong reflection model is basically a simplified method of deciding the shade of a specific point on a 3D surface. It doesn't take into account second-order reflections often found in raytraced or diffuse rendering. To compensate an extra ambient lighting term is added to the scene that is rendered. 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. There are three factors on which lightning effect depends on: Light Source : Light source is the light emitting source. There are three types of light sources: WebThe lighting model used is the Blinn-Phong model, which is a simplification of the Phong model. We shall take a peek at the Phong model since it makes it easier to understand the Blinn-Phong model.
