I've watched a bunch of different videos about Ray Tracing and Path Tracing and they all say that the rays fly out of the camera and reflect off the surface, the difference is that in Path Tracing many rays will reflect in random directions, while in Ray Tracing a single ray will reflect and fly directly to the light source. This raised a lot of questions in my mind, how do reflections, shadows, transparent materials, etc. work in Ray Tracing, but no one in their videos even thinks about it, they just reflect a ray once and that's it. I finally found this video that explained literally everything and answered all my questions, it's literally a diamond for me, thank you
This channel will absolutely age well...
hats off.
