Flat, Gourand and Phong shading:
They differ in the moment, when they compute the surface normals for lighting. Which shader is defining the final normal to be used for lighting computation?
Flat shading: Vertex Shader
Gouraud shading: Vertex Shader
Phong shading: Tessellation Shader
Flat, Gourand, Phong shading:
Similar to the question before, which shader is the last one to have an influence on the color to be applied to the pixel later on?
Flat shading: vertex shader
Gouraud: Tessellation Shader
Phong: Fragment Shader
