Flat shading does not look realistic: Gouraud shading is better. OpenGL uses scan-line interpolationto assign a colour at each point of a projected polygon as a weighted average of given vertex colours. Consider, for example, the projected polygon below, with four vertices c0, c1, c2, c3, c 0 c 2 c 5 c 3 c 4 c 1 c 6 Scan line Web- For flat shading OpenGL uses the normal associated with the first vertex of each polygon - For triangle strips OpenGL uses the normal of the 3rd vertex for the 1st polygon, 4th vertex for 2nd poly,…..
