What is the visual significance of averaging the "area" normal, i.e, attaching triangle area to the magnitude if the normal? I noticed that when I normalize before averaging (i.e remove the effect of magnitude), then the per-vertex shading looks different than with weighed normals. What is the theoretical reason for weighing the normals by the triangle area?
