Out: Lecture Notes

Illumination Models

Adapted from Peter Stephenson
for CP2060 Graphics

The notes for these lectures were taken from the former CP2060 text by Foley & Van Dam et al - "Introduction to Computer Graphics", 1994.

The current text, by Hill, uses somewhat different conventions, but arrives at the same overall result - see chapter 8 - Rendering Faces for Visual Realism.

It is valid to see here the two different versions of the same material and to be able to equate them. (The Hill style is perhaps somewhat easier to follow (and to write)).

Check out this cool Java applet for lighting spheres! (later...)
You can adjust the values of the variables in the lighting equation and see the results. Change views, change scene, add attenuation...
