Lecture 13: Global Illumination & Path Tracing (24)

A question about the psuedo code: I’m a little bit confused by what exactly is "intersect(x, wi)" returning, and why it should be passed into the radiance function? I thought that here x is equivalent to the P the previous side, and shouldn't L directly take in (P, -wi) instead of (intersect(P, wi), -wi)?

Is it possible that the calculated L is zero, as in it didn't hit a light source?
