Kajiya’s rendering equation (1986) unifies all light transport: [ L_o(p, \omega_o) = L_e(p, \omega_o) + \int_\Omega f_r(p, \omega_i, \omega_o) , L_i(p, \omega_i) , \cos\theta_i , d\omega_i ] where (L_e) is emitted radiance. This is a Fredholm integral equation of the second kind.
Physically based rendering requires precise measurement of light. 6.4400 computer graphics
Start by explaining that computer graphics isn't just about video games or movies. It’s about simulating the physical world through light and geometry. Mention that 6.4400 is the "bread and butter" introductory course at MIT for anyone wanting to understand how images are actually built from scratch. 2. The Core Pillars of the Course \omega_o) = L_e(p
