Hi Amit,
Phong, Gouraud, and Flat shading are three techniques used in rendering materials:
*Flat Shading:
Assigns a single color to each polygon, creating a flat appearance without smooth transitions.
Computationally less intensive, suitable for real-time rendering on low-powered devices or for stylized aesthetics.
*Gouraud Shading:
Interpolates vertex colors across polygons, resulting in smoother shading transitions.
Provides more realistic lighting effects compared to flat shading but may have interpolation artifacts, especially on curved surfaces.
Strikes a balance between visual quality and performance, commonly used in real-time graphics applications.
*Phong Shading:
Calculates surface normals at each pixel for smoother transitions and accurate lighting.
Offers higher visual fidelity, especially for highlights and reflections.
More computationally intensive than Gouraud shading, requiring greater processing power for real-time performance.
In summary, the choice between these shading models depends on the desired balance of visual quality and computational efficiency for a given application.
Hope this resolves your query.
