Merits -Phong shading or Normal Vector Interpolation Shading
Hence by finding intensities at various points across the edge we determine the intensity that is varying across the edge among two vertex points and is not uniform like in Gouraud Shading, providing much good effect. Thus we can say as the normal vector interpolation by Phong shading is better to intensity interpolation method as in Gourand Shading since it largly reduces the mach bands.
A triangle is having the vertices A(0,0) B(1,2) and C (5,2).Magnify the triangle to thrice it''s size while keeping C(5,2) fixed
Local Illumination Model - Polygon Rendering In this only light that is directly reflected by a light source through a surface to our eyes is observed. No explanation is taken
Advantages of Scan line Algorithm: This time and always we are working along with one-dimensional array as: x[0...x_max] for color not a 2D-array like in Z-buffer algorithm.
