Understanding lights, light sources and surfaces by adding them to my Raytracer!

In our previous video we discussed about the very basics of Raytracing like the 3d coordinate system, the view port, scene to canvas mapping, very basic rendering of our scene to our canvas, representing light rays using vectors, intersection of light rays to the objects in the scene etc.
In this video we will add light sources to our scene and try to understand how the light coming from those sources affect our viewing of the objects depending on their surfaces. Different surfaces reflect light in different ways and that determine how they appear.
