"For Phong shading, the surrounding vertex normals are interpolated for each pixel and the pixel is then illuminated with the interpolated normal.

a) Calculate the interpolated normal at the three middle points. The normal can be interpolated component-wise like the vertex color, but the normal must always be scaled back to length 1.

b) Calculate the color at point M under Phong shading.

c) What color would be produced at the three middle points under Gouraud shading?"

Lichtfarbe =(1,1,1) Ambiente Lichtfarbe =(0,0,0) Keine Attenuation gesetzt, d.h. die Entfernung zur Lichtquelle spielt keine Rolle
