Complete picture


Orthographic views of wire frame


Wireframe with perspective


Wireframe with hidden lines


Constant shading (ambient emission from each face)


Faceted shading (diffuse illumination calculated for each face)
Note Mach bands and polygonal silhouettes


Gouraud shading (diffuse illumination calculated at each vertex and interpolated across face)


Gouraud shading with specular highlights (adding specular illumination at each vertex and interpolating)


Phong shading (calculate normal at each vertex, interpolate across face, and calculate diffuse and specular illumination at each pixel)


Advanced illumination


Texture mapping


Bump mapping


Reflection mapping
