WebGouraud surface shading was developed in the 1970s by Henri Gouraud. It is the interpolation technique. Intensity levels are calculated at each vertex and interpolated across the surface. Intensity values for each polygon are matched with the values of adjacent polygons along the common edges. This eliminates the intensity discontinuities that ... WebThe following is Phong Shading and Gouraud Shading for light positon (20,0,20) and n = 100: The default value is [0,1,0].
