Lighting
•Lambertian
(diffuse) surfaces
–Radiant
intensity has cosine fall off with respect to angle
–Radiance is constant with respect to angle
–Reason: the projected unit area ALSO gets smaller
as a cosine fall off!
–Fatt x I x Kd x (N • L)
N
V
I µ length = cos(t)
Radiance intensity: intensity/solid angle
