WebPhong is a very basic, but real looking light model for surfaces that has three parts: ambient, diffuse, and specular lighting. Ambient Lighting: Ambient lighting is the simplest of the three parts to understand and calculate. Ambient lighting is light that floods the scene and lights up the object evenly in all directions.

WebNorthwestern Computer Science WebMar 9, 2024 · What Does Phong Shading Mean? Phong shading is a specific type of shading technique in 3-D computer graphics that is useful for smoothing out multi-surface shapes and creating more sophisticated computer-modeled images. Experts refer to the technique as “interpolation,” where Phong shading visualizes a smoother surface for a 3-D model.
